I had a thesis two months ago that you could detect predictors with insider knowledge and ride their coat tails and spent some amount of time staring at the data and running some ML algos to detect them. I learned some things about the market during this time, but did not succeed in my detection algorithm.
* Polymarket is a bit more transparent with who placed what bet, so it's a good place to go to study winners.
* The most consistent Polymarket winner I saw was placing 95%+ odds many, many times a day.
* Most markets will have a surprisingly small liquidity, so if your edge is just 5% you won't make as much as a 5% edge in the stock market could make you. This is good in that it keeps the biggest fish out, but some big players seem to be using strategies based on holding the most chips.
* Paper trading in Polymarket/Kalshi is very different than paper trading in the stock market, because even a few grand in Polymarket/Kalshi can have a big impact in how other "traders" interact with you. The traditional paper trade validation -> unleash the bot strategy doesn't work. You need to real trade with real money and scale up while watching how the market responds.
EDIT: Bonus learning -- yes the market runs by getting fish into the system. That's why Kalshi is advertising so much, it attracts suckers for the professional to win from, all while Kalshi takes a percentage.
I used to play penny stocks for fun and it was a blast to be doing $3000 trades and be responsible for 30% of the volume for the day. You can learn a lot about how markets work if you adopt a penny stock, particularly the kind that trades in a wide range where you can buy in at 0.03 and figure "I'll sell when it hits 0.12" and sooner or later it does... then falls back down to 0.02.
This is interesting to me. I never had any enjoyment from traditional gambling when I dabbled in it. But I like the idea of being an expert on a little-known company and experiencng the response of my actions. Of course, it would be "for entertainment purposes only."
You can "trade the news" with penny stocks (this is basically just buying when people first start talking about it then selling when more people are talking about it), but like you say, the liquidity is soooooo low that you have to be really careful if you plan to sell more than a few hundred dollars.
Generally, you're going to lose money - so don't do it.
Like any kind of gambling you have to do it with money you can't afford to lose and if you want exposure to stocks it is hard to say that you shouldn't have a big chunk of your savings in something like $QQQ or $VOO.
Myself I was working on finance-adjacent stuff at the time and thought it had educational value. I did OK trading my favorite penny stock but I've had my share of financial misadventures, like I just had to buy $XIV because I wanted to see what happened and... I did.
I used to work for a sports betting company that identified individuals who were a little too good. The key is to remember that they are addicts and will bet on events regardless of if they have insider knowledge or not, so you have to account for this and not only identify the individuals with insider knowledge, but also what events they have that knowledge about and what they don't.
every casino's business model is about get-in-the-door appeal in order to fish out a handful of very lucrative whales. polymarket included. so no they're not really comparable.
The only winners are the market makers and the ones initiating insider trading. You'll always be on the wrong is of the liquidity when trying to ride alongside scammers.

I am unfamiliar with working with such signal-to-noise ratios.
* I only had the example trades in the news as 100% confirmed positive trades.

Just following up on these types of trades didn't provide a very big edge, as the nature of the trade adjusts the payout percentage.
> In Polymarket you can just spin up a new account. If an account spins up, makes a $50k bet and wins
You'd probably want to use some form of bayesian ranking, like say add 1k of total bets and 500 in total winnings to the raw scores.
But your bigger problem is just that people spinning up new accounts may be doing it to avoid your tracking. The kind of person with lots of evidence that they're good should be smart enough to know about copycat traders. The evilest among them might use a small bet to lure copycats and then trade against them in alts.

But what evidence is there that anyone is "good"? The fact that I am an insider to one event does not make me an insider to all events. If I were an insider to many events, I would probably have better ways to profit off of them. Placing a big bet is something I would do if I knew one thing.
This is the trap of modern society. Think about what you're doing: instead of anything productive, you thought a good use of your time was sitting there staring at numbers, hoping to find a pattern to make money off of people; who in their own right are using insider information to game a system; which itself is set up to capitalize off the fact that the larger economy has failed, and now all that's left is to just make money off of guessing.

I would recommend you look into Bullshit Jobs by David Graeber, where he makes an argument that 50% of American jobs are not only not-productive, but actually harmful. Your argument isn't taken to its logical conclusion yet.
I'm well aware of "Bullshit Jobs", but that's more support for my conclusion that the modern economy has failed. Why do we have people doing bullshit jobs rather than something else? My argument is taken to its logical conclusion plenty of places in this economy, it's just not evenly distributed -- just look at the minimum wage being $7/hr juxtaposed next to an extra value mean being $12. That's a failed economy, sorry.
There's a lot I could unpack here, but I'm just going to pull on the string I find most interesting. "Why do we have people doing bullshit jobs rather than something else?"
There honestly isn't that much else left to do. Most of us in the western world are incredibly well fed, well housed, well transported, well educated, well defended, and well cared for(health/dental). Sure, all of that could be better and/or cheaper, but by historical standards we are doing incredibly well. We're engaging in all of these activities with only a fraction of the people that were spent on it in the past, and the people that are working directly in these fields are more productive than ever.
We're talking care of our societal needs with fewer people than ever before. What exactly do you expect the rest of us to do with our time and how will it be anything other than bullshit?
No, there's toooons of work to do. It sounds like you and yours are doing fine. My community is hungry, sick, lacks access to education, faces striking illiteracy, are not only not defended by but are actively attacked by local police and security forces.
> What exactly do you expect the rest of us to do with our time and how will it be anything other than bullshit?
Well there's a national childcare crisis going on where childcare costs more than a mortgage. There's also an education crisis going on where education costs more than people make in 10 years. There's a housing crisis going on where people can't into homes and are becoming forever renters. There's a healthcare crisis going on where people cannot actually afford to go to the doctor or have to ration their medications to get the care they need -- even with insurance. So my proposal would be to take people a way from doing bullshit jobs and get them into those professions to help out with those various crises.
There are so many problems in the world, you really can't think of anything that would be helped by someone well educated and motivated to work on any of those problems?
People going hungry, unhoused, traumatized, the Earth's warming, there's cancer. Getting funding for those things is also hard, but that's also a job!
We should be happy to live in a world where a significant fraction of people can conclude that "doing something productive" is not a hard requirement for survival.
I did blame the system, I said it's the trap of modern society. The only reason hx8 fell into this trap was because they thought it would be profitable, that's not a moral failing on the part of the poster.
Finance has always been the largest sector on the planet through every economic environment you have been alive for, I don't really understand why there is a current of this community that acts so divorced from its perpetual and all encompassing existence their whole lives
Despite you being an individual, you reflect an aberration of sentiment here that makes no sense
For example, the larger economy hasn't failed, another view is that this is price discovery of a mispriced agent in the market. A wage worker whose actual productivity isn't valued accurately, and a market based solution has been developed that allows for closer accuracy. More profits to the insider and the copy trader, their available capital and liquidity is derived from their utility to the employment sector and their potential profits with that capital and liquidity is derived from the event's actual utility to the market.
Additionally, the productivity of all agents isn't known, you don't know what they were doing with their time before and it likely was suboptimal already - as in doomscrolling on social media or vegetating on the couch.
Finally, you have no way of quantifying if those lazy things were suboptimal uses of time, or if a completely active other activity was suboptimal or optimal, as this goes into relative utility and schools of ethics.
It's only a matter of time until Social Security starts to fail, right after we've paid all the boomers their full benefits (and just in time for me to be eligible), and then they'll have to implement "austerity measures." After that, groceries, gas, housing, health "care," and higher education will have fully broken the middle class (it's already broken me, and I have a good job and a paid-off house), and the economy (sans imaginary AI investment bullshit) will be exposed as failing. AI (such as it is) will hammer entry level jobs, and tax revenues will be impacted by this. At the same time, we're going to have to start some sort of menial UBI, but with what money, I have no idea. Service on the national debt just surpassed military spending last year. When the shit hits the fan in another 10 years, the country will have to either go to war to reset the accounting ledgers, or actually put themselves on a budget. Which do you think will happen?
Given the numbers and rates we can see at present, all economic activity right now is a process of moving deck chairs on the Titanic. Sure, it hasn't failed, but it is an absolute certainly that it WILL. It's just a question of WHEN, and it's relatively soon. We have no adults in Washington. It's clear they're ALL just trying "get theirs" before it all comes crashing down.
When social security "fails" (which I would define as not paying out 100% of its defined benefits), the payment structure will be changed and that's the end of it.
If paying for basic living expenses and higher education for your kids has "broken you", then you either didn't have the good job you thought you did or you aren't making very sound financial decisions (or both). Given that you own a paid off house, I suspect the actual issue is a complete lack of perspective on your part as to how well you have it.
In short, the economy is not failing, you're just a doomer.
Everything you described is future liquidity and who has it, but whether that’s the economy or enough of it to make a statement is unclear to me
And you wrote this all as a reaction to people trading on prediction markets? Markets that show velocity of transactions in a new, novel and growing way, which is the goal of our economies - to discourage hoarding in favor of transactions
Being a permabear doomer has nothing to do with the existence of prediction markets and other people’s participation in them
This whole prediction market space seems like a 2026 version of ball and cup game betting. Most of the people participating fail to understand that they (and their pointless bets up for harvesting) are the product here.
My intuition is that it is a lot like sports betting: many laypeople bet for what they hope will happen, rather than trying to beat the market earnestly.
The winners, as you point out, are the house and those with insider knowledge.
I realize I'm an N of 1, but I've participated in prediction markets since 2019 and am just above 5 figures in profit. Not life-changing money, but it certainly doesn't hurt.
I'm pretty conservative in my predictions and just think there is a lot of free money on these sites. Maybe that just supports the sentiments of this article and most of the negative comments on this post.
There are certainly cases where I got run over by the steamroller picking up nickels, but in general that's few and far between. A good example is getting trump losing the 2020 election at 90% after the election in November. If you find those types of markets and compound the earnings it's a pretty nice savings account.
I've also been burned by insider trading and vague rule interpretations but at this point, you chalk it up to the nature of prediction markets. I now try to stay away from markets that are more manipulative (e.g. mention markets).
I don't understand the hostility to prediction markets. There are definitely hedging opportunities and we're all adults.
Have you heard of the Sucker Effect? Your gains come solely from the those who made the wrong bet. There is no inherent value generation in the prediction markets unlike the stock markets. Yes, there is money to be made, but at a net loss to the society, so many would not consider these bets "opportunities" but rather "gambling".
There is no value generation in trading stocks either beyond IPO, as stocks are then simply second-hand markets and can be completely irrational. The main value is just like the lottery : entertainment, excitment.
There is value beyond IPO- companies continue to sell ("issue") shares on the public market as a way of generating cash. They also buy back shares when with excess cash, usually when the market value is low but sometimes, irrationally IMO, when it is high. They also use this as an incentive-backed compensation pool. The relative value of these is debatable, but I don't think it is correct that post-IPO public shares are just traded between third-parties making short-term bets. Happy to be corrected.
Define "net loss to the society." Society is just a group of individuals. If my counter-party was a democratic aide hedging that they wouldn't have a job come January, was it a real loss for them? The money I've earned on prediction markets has certainly allowed me to spend more money in the economy. What if a trump supporter watching the market saw what a longshot it was and decided not to go to the Capitol on January 6th?
The value generation is for passive observers: it is theoretically more informative to be told that there is a y% chance of x from someone with a financial incentive to be right.
(also, we allow plenty of zero and negative sum interactions in society. I don't know why this is special.)
I think the problem with prediction markets is the ease of people changing the outcome and profiting on it from others expense.
It’s worse than insider trading as it’s betting that Kyle’s mom will bomb Gaza and then making it happen.
Any societal good from knowing is outweighed by the injustice.
If there was any regulation by government or the markets themselves then it would be better. Betting in things you can’t affect like the weather or earthquakes or elections or whatever is actually pretty useful for awareness.
I understand the hostility to them getting into sports betting since that seems to trigger a particular unhealthy impulse in young men but your anger should be first directed at the companies that are 100% sports betting (DraftKings and their ilk). I don't think the normal things prediction markets do subject young men to the same temptations.
Prediction markets are nothing more than gambling. Most people who gamble end up losing. If it were otherwise, running a gambling operation wouldn't be the enormously profitable endeavor that it is.
I ran the earliest predictions market online at the reboot of The Industry Standard.
Prediction markets fatally suffer from two
Problems.
1) large sharks making huge bets at the end (destroying any signal from earlier bets)
2) inside information on poorly written bets.
The solution is -parlay- edit: parimutuel style payouts but that destroys popularity (you are paid out at closing odds not at your time of bet odds spread to sell position).
I thought the entire point of prediction markets was to attract insiders with a way to turn their knowledge into cash. Doesn't that imply that everybody else is going to be net negative?
That's why death pools were supposed to be equivalent to assassination markets. Somebody would kill the person to win.
The only way (I would think) to make money if you're not an insider is to take advantage of the fact that most people believe in the Law of Averages and consistently err to moderation, so they overestimate small chances and underestimate large chances. Just bet with the crowd when the crowd (and reason) is overwhelmingly on one side. That depends on the vig being low enough not to obliterate that little bit of expected profit, though.
Everytime someone loses money on a bad bet in a prediction market, it's an opportunity for them to learn something about ~~counter-party risk~~ adverse selection. You could easily make the argument that the more people are losing in prediction markets, the more learning is happening.
Counterparty risk would be more like the betting site going belly-up and not getting money out despite having a profitable trade. This is just regular risk.
Not only that, huge UMA tokens holders can also rig some bets on a technicality without much effort, especially since big UMA token holders seems to know each others. If you bet against Zelansky wearing a suit to meet Trump, and that by all account, he seemed to be wearing a suit, but you don't want to loose the bet, the "Oracle"/UMA holders can decide that it wasn't, in fact, a suit, and your bet will win.
I don't see how regulating authorities could truly decipher the distinction between incompetence and pyramid hype fraud / shell company money laundering schemes at scale.
The twisted thing about it is that the surface logic of putting a hit on someone via prediction market involves betting that they'll stay alive. How innocuous looking.
> On Kalshi, too, losers vastly outnumber winners. Spokeswoman Elisabeth Diana said there are 2.9 unprofitable users for each profitable one based on data from the past month
So 25% of users are profitable? That's vastly more than on financial sites - stocks/futures/forex/options trading where only 5% of bettors are profitable.
> vastly more than on financial sites - stocks/futures/forex/options trading where only 5% of bettors are profitable
Source? I'm not doubting that there are products and forums where 95% of traders lose money. But that's far from representative for most financial-market participants.
10 year old paper on forex trading. 85% of losers here.
> The average trader is in the dataset for almost exactly six months (181 days). This is the amount of time between a trader’s first and last trade. About 25% of traders leave the sample within the first 46 days, while 50% of traders exit the sample within 155 days. Of the 181 days on average between open and close, traders are actively trading on an average of 50 of those days. The average trader has an equal-weighted return per trade of -0.035%, and very few traders quit while ahead. That traders have such small average returns per trade is not surprising given that the median trade is open for only 16 minutes, as can
be seen from Panel B. Only 16.2% of traders are profitable upon exiting the sample.
It's the same loss percentage for stocks day trading. The loses do not come mainly from the zero sum/fees, they come from the lack of alpha.
> Depending on the source, only around 3% to 20% of day traders make money. But that 20% estimate probably has as much to do with the time period studied—the dotcom bubble. It's hard to know for sure, but it's probably fair to say that up to 95% of day traders lose money.
The Investoperia article cites three sources for that claim, the second which claims one third [1].
One fifth to one third is more in line with what I expected. It’s also a range materially higher than 5%. Broadly speaking, you’ll see 90/10 to 95/5 in zero-sum markets like FX and derivatives, and 80/20 to 70/30 for capital markets.
All those other markets are vastly bigger in scale and trade in trillions on a daily basis so it's an irrelevant comparison. Also the expectation is that the majority of that 25% are insiders. So you're comparing catching fish in a barrel where 25% of the participants hooked the fish prior to you getting a turn vs fishing in the open ocean (so 5% is pretty good with additional voting rights/tax benefits).
People keep saying they provide the market with information, and that's the benefit of allowing the insider trading, but no one has pointed out how in any way society has benefitted from the insider trading instances so far...
The answer is pretty obvious, right? It doesn’t reliably deliver on that promise, and in the meantime they rake billions on unregulated gambling with near zero institutional exposure.
For sure I agree, but was of course severely downvoted every time I asked how anyone besides the inside trader benefit. Aaaand now I'm being downvoted again.
It's useful for things like elections, where though popular media might push one line of thought primarily, the markets will adjust to be closer to the reality. Pretty visible in the 2024 elections where if you followed mainstream media at all, you probably wouldn't realize the markets had Trump at a 60% chance to win just before the election.
But for so many things, there's just too many sources of insider info. Reality television especially, the last couple seasons of Survivor have been clearly leaked if you look at a prediction market. And since all of production knows, and obviously all the players know, someone tells their family members, and all of a sudden you have a few hundred people who know for sure who will win.
The 2024 prediction market had like several large bettors on the Trump side https://www.bloomberg.com/news/features/2024-10-25/polymarke.... The Harris side had no equivalent counter-whales. So the ~60% Trump prediction was not really reflecting reality, more-so individual conviction. A more retail-only market would likely have priced it closer to 52–55% Trump, which matches with what the pollsters and mainstream media said.
>It's useful for things like elections, where though popular media might push one line of thought primarily, the markets will adjust to be closer to the reality.

How did that number more greatly reflect reality than the polls?

Pretty visible in the 2024 elections where if you followed mainstream media at all, you probably wouldn't realize the markets had Trump at a 60% chance to win just before the election.
But what exactly is the use of that? And as another example from the 2024 elections, every media outlet was pushing the validity of some stupid Iowa poll that only insiders even knew about, and was obviously just a random survivor that happened to get a few things right in a row. The prediction of a Harris landslide entirely flipped the odds in the prediction markets; if you had insider knowledge about that poll, you would have been able to make a fortune. If you had helped market that poll, you could have made a fortune.
The problem with prediction markets as predictors I think is that that they assume there will be a lot of insiders, rather than a very few. It gets confused with normal price discovery in a large, diverse and competitive market. Instead, prediction markets just match the (opinion) x (perceived trustworthiness) of the media landscape. If anything, insiders have a motivation to push the markets to be more inaccurate. They want to bet against them.
edit: but to restate my initial question - what's the use of polls that converge to the correct answer about 10 seconds before the actual votes come in? I asked the same thing when people were lusting over Nate Silver, and I still haven't gotten an answer. I understand using polls to guide your election expenditures; I do not understand the intense interest in them among spectators, or when the election is already mostly run.

I'm not a gambler, but when I consider it I think the worst thing that could happen to me would be to win a substantial but not life-changing amount of money. I think that's where most people get hooked. They get lucky once (or a few times), then get completely sucked in trying to replicate that success.

This is like saying that "Supersize me" is free publicity for MacDonalds.
No such thing as bad publicity? I would bet that McDonalds saw an uptick in sales after the release of SSM.

No, there's toooons of work to do. It sounds like you and yours are doing fine. My community is hungry, sick, lacks access to education, faces striking illiteracy, are not only not defended by but are actively attacked by local police and security forces.
> What exactly do you expect the rest of us to do with our time and how will it be anything other than bullshit?
Well there's a national childcare crisis going on where childcare costs more than a mortgage. There's also an education crisis going on where education costs more than people make in 10 years. There's a housing crisis going on where people can't into homes and are becoming forever renters. There's a healthcare crisis going on where people cannot actually afford to go to the doctor or have to ration their medications to get the care they need -- even with insurance. So my proposal would be to take people a way from doing bullshit jobs and get them into those professions to help out with those various crises.
> There honestly isn't that much else left to do.
There are so many problems in the world, you really can't think of anything that would be helped by someone well educated and motivated to work on any of those problems?
People going hungry, unhoused, traumatized, the Earth's warming, there's cancer. Getting funding for those things is also hard, but that's also a job!
We should be happy to live in a world where a significant fraction of people can conclude that "doing something productive" is not a hard requirement for survival.
True, but hx8 isn't to blame here and was simply trying an interesting experiment. Blame the system instead.
I did blame the system, I said it's the trap of modern society. The only reason hx8 fell into this trap was because they thought it would be profitable, that's not a moral failing on the part of the poster.
The real trap of modernity is treating "productivity" as some sort of quasi-religious moral imperative.
Finance has always been the largest sector on the planet through every economic environment you have been alive for, I don't really understand why there is a current of this community that acts so divorced from its perpetual and all encompassing existence their whole lives
Despite you being an individual, you reflect an aberration of sentiment here that makes no sense
For example, the larger economy hasn't failed, another view is that this is price discovery of a mispriced agent in the market. A wage worker whose actual productivity isn't valued accurately, and a market based solution has been developed that allows for closer accuracy. More profits to the insider and the copy trader, their available capital and liquidity is derived from their utility to the employment sector and their potential profits with that capital and liquidity is derived from the event's actual utility to the market.
Additionally, the productivity of all agents isn't known, you don't know what they were doing with their time before and it likely was suboptimal already - as in doomscrolling on social media or vegetating on the couch.
Finally, you have no way of quantifying if those lazy things were suboptimal uses of time, or if a completely active other activity was suboptimal or optimal, as this goes into relative utility and schools of ethics.
> the larger economy hasn't failed
It's only a matter of time until Social Security starts to fail, right after we've paid all the boomers their full benefits (and just in time for me to be eligible), and then they'll have to implement "austerity measures." After that, groceries, gas, housing, health "care," and higher education will have fully broken the middle class (it's already broken me, and I have a good job and a paid-off house), and the economy (sans imaginary AI investment bullshit) will be exposed as failing. AI (such as it is) will hammer entry level jobs, and tax revenues will be impacted by this. At the same time, we're going to have to start some sort of menial UBI, but with what money, I have no idea. Service on the national debt just surpassed military spending last year. When the shit hits the fan in another 10 years, the country will have to either go to war to reset the accounting ledgers, or actually put themselves on a budget. Which do you think will happen?
Given the numbers and rates we can see at present, all economic activity right now is a process of moving deck chairs on the Titanic. Sure, it hasn't failed, but it is an absolute certainly that it WILL. It's just a question of WHEN, and it's relatively soon. We have no adults in Washington. It's clear they're ALL just trying "get theirs" before it all comes crashing down.
Social security will fail slowly by reducing its payout a little at a time.
It can’t really fail all at once unless the US government dissolves. And people have been losing money on that bet for 250 years.
Luckily, if someone thinks the USG will actually fail, it’s really easy to trade on that possibility.
When social security "fails" (which I would define as not paying out 100% of its defined benefits), the payment structure will be changed and that's the end of it.
If paying for basic living expenses and higher education for your kids has "broken you", then you either didn't have the good job you thought you did or you aren't making very sound financial decisions (or both). Given that you own a paid off house, I suspect the actual issue is a complete lack of perspective on your part as to how well you have it.
In short, the economy is not failing, you're just a doomer.
Everything you described is future liquidity and who has it, but whether that’s the economy or enough of it to make a statement is unclear to me
And you wrote this all as a reaction to people trading on prediction markets? Markets that show velocity of transactions in a new, novel and growing way, which is the goal of our economies - to discourage hoarding in favor of transactions
Being a permabear doomer has nothing to do with the existence of prediction markets and other people’s participation in them
This whole prediction market space seems like a 2026 version of ball and cup game betting. Most of the people participating fail to understand that they (and their pointless bets up for harvesting) are the product here.
My intuition is that it is a lot like sports betting: many laypeople bet for what they hope will happen, rather than trying to beat the market earnestly.
The winners, as you point out, are the house and those with insider knowledge.
It’s extremely like sports betting, because the vast majority of their volume is sports betting.
... like a horse that is held back for a while and comes in at 23-1.a
I realize I'm an N of 1, but I've participated in prediction markets since 2019 and am just above 5 figures in profit. Not life-changing money, but it certainly doesn't hurt.
I'm pretty conservative in my predictions and just think there is a lot of free money on these sites. Maybe that just supports the sentiments of this article and most of the negative comments on this post.
There are certainly cases where I got run over by the steamroller picking up nickels, but in general that's few and far between. A good example is getting trump losing the 2020 election at 90% after the election in November. If you find those types of markets and compound the earnings it's a pretty nice savings account.
I've also been burned by insider trading and vague rule interpretations but at this point, you chalk it up to the nature of prediction markets. I now try to stay away from markets that are more manipulative (e.g. mention markets).
I don't understand the hostility to prediction markets. There are definitely hedging opportunities and we're all adults.
Have you heard of the Sucker Effect? Your gains come solely from the those who made the wrong bet. There is no inherent value generation in the prediction markets unlike the stock markets. Yes, there is money to be made, but at a net loss to the society, so many would not consider these bets "opportunities" but rather "gambling".
There is no value generation in trading stocks either beyond IPO, as stocks are then simply second-hand markets and can be completely irrational. The main value is just like the lottery : entertainment, excitment.
There is value beyond IPO- companies continue to sell ("issue") shares on the public market as a way of generating cash. They also buy back shares when with excess cash, usually when the market value is low but sometimes, irrationally IMO, when it is high. They also use this as an incentive-backed compensation pool. The relative value of these is debatable, but I don't think it is correct that post-IPO public shares are just traded between third-parties making short-term bets. Happy to be corrected.
There is strong signal that companies then listen to and act on. The market serves (whether you like it or not) as the final board of executives.
Define "net loss to the society." Society is just a group of individuals. If my counter-party was a democratic aide hedging that they wouldn't have a job come January, was it a real loss for them? The money I've earned on prediction markets has certainly allowed me to spend more money in the economy. What if a trump supporter watching the market saw what a longshot it was and decided not to go to the Capitol on January 6th?
The value generation is for passive observers: it is theoretically more informative to be told that there is a y% chance of x from someone with a financial incentive to be right.
(also, we allow plenty of zero and negative sum interactions in society. I don't know why this is special.)
This one is regulated as a commodities derivative rather than gambling

I think the problem with prediction markets is the ease of people changing the outcome and profiting on it from others expense.
It’s worse than insider trading as it’s betting that Kyle’s mom will bomb Gaza and then making it happen.
Any societal good from knowing is outweighed by the injustice.
If there was any regulation by government or the markets themselves then it would be better. Betting in things you can’t affect like the weather or earthquakes or elections or whatever is actually pretty useful for awareness.
> Betting in things you can’t affect like the weather
get a hairdryer and you too can control the weather
I understand the hostility to them getting into sports betting since that seems to trigger a particular unhealthy impulse in young men but your anger should be first directed at the companies that are 100% sports betting (DraftKings and their ilk). I don't think the normal things prediction markets do subject young men to the same temptations.

Prediction markets are nothing more than gambling. Most people who gamble end up losing. If it were otherwise, running a gambling operation wouldn't be the enormously profitable endeavor that it is.
Unregulated gambling, mind you. Huge difference.
I feel that way about what the stock market has become, too.

I ran the earliest predictions market online at the reboot of The Industry Standard.
Prediction markets fatally suffer from two Problems.
1) large sharks making huge bets at the end (destroying any signal from earlier bets)
2) inside information on poorly written bets.
The solution is -parlay- edit: parimutuel style payouts but that destroys popularity (you are paid out at closing odds not at your time of bet odds spread to sell position).
"The solution is parlay style payouts"
I think you mean parimutuel payouts?

I thought the entire point of prediction markets was to attract insiders with a way to turn their knowledge into cash. Doesn't that imply that everybody else is going to be net negative?
That's why death pools were supposed to be equivalent to assassination markets. Somebody would kill the person to win.
The only way (I would think) to make money if you're not an insider is to take advantage of the fact that most people believe in the Law of Averages and consistently err to moderation, so they overestimate small chances and underestimate large chances. Just bet with the crowd when the crowd (and reason) is overwhelmingly on one side. That depends on the vig being low enough not to obliterate that little bit of expected profit, though.
Everytime someone loses money on a bad bet in a prediction market, it's an opportunity for them to learn something about ~~counter-party risk~~ adverse selection. You could easily make the argument that the more people are losing in prediction markets, the more learning is happening.
Every time a drug addict uses, they’re actually learning about biology and the sociology of addiction.
Counterparty risk would be more like the betting site going belly-up and not getting money out despite having a profitable trade. This is just regular risk.
You're right, but I was confusing counterparty risk and adverse selection.
Betting venues can make money on transaction volume rather than holding an edge against their customers on the actual bets.
only if such venues are Parimutuel.
If by "sharks" you mean "inside traders" then yes.
I took it to be like a pool shark. https://en.wikipedia.org/wiki/Glossary_of_cue_sports_terms#s...
Yes, that'd be the grammatically correct use. But Insider trading has been rampant on the "prediction markets". In short, it's a scam, because gambling is always a scam. https://fortune.com/2026/04/26/prediction-markets-insider-tr...
Not only that, huge UMA tokens holders can also rig some bets on a technicality without much effort, especially since big UMA token holders seems to know each others. If you bet against Zelansky wearing a suit to meet Trump, and that by all account, he seemed to be wearing a suit, but you don't want to loose the bet, the "Oracle"/UMA holders can decide that it wasn't, in fact, a suit, and your bet will win.
What's the difference between penny stocks and prediction markets?
The authorities heavily regulate penny stocks since Boiler rooms.
I don't see how regulating authorities could truly decipher the distinction between incompetence and pyramid hype fraud / shell company money laundering schemes at scale.
SEC cares about penny stocks a little bit.
I can't put a hit out in someone I don't like by buying penny stocks, but I can by placing a prediction market bet.
The twisted thing about it is that the surface logic of putting a hit on someone via prediction market involves betting that they'll stay alive. How innocuous looking.
So, the same as NFT's and Memecoin from the same people...
Prediction markets are astrology for the boys.
Astrology is magical thinking and fraud so it checks out.
Astrology is more of a cost centre than a gambling venue, unless you consider choosing a life partner based on the stars.
> On Kalshi, too, losers vastly outnumber winners. Spokeswoman Elisabeth Diana said there are 2.9 unprofitable users for each profitable one based on data from the past month
So 25% of users are profitable? That's vastly more than on financial sites - stocks/futures/forex/options trading where only 5% of bettors are profitable.
Are you confusing beating the market with being profitable?
The majority of active traders won't beat the market (e.g. the S&P 500). That doesn't mean they aren't profitable.
> vastly more than on financial sites - stocks/futures/forex/options trading where only 5% of bettors are profitable
Source? I'm not doubting that there are products and forums where 95% of traders lose money. But that's far from representative for most financial-market participants.
10 year old paper on forex trading. 85% of losers here.
> The average trader is in the dataset for almost exactly six months (181 days). This is the amount of time between a trader’s first and last trade. About 25% of traders leave the sample within the first 46 days, while 50% of traders exit the sample within 155 days. Of the 181 days on average between open and close, traders are actively trading on an average of 50 of those days. The average trader has an equal-weighted return per trade of -0.035%, and very few traders quit while ahead. That traders have such small average returns per trade is not surprising given that the median trade is open for only 16 minutes, as can be seen from Panel B. Only 16.2% of traders are profitable upon exiting the sample.

It's well known in the industry that about 90% of traders drop before 1 year.
> But that's far from representative for most financial-market participants.
I specifically mentioned "bettors" - day traders/speculators, not long time investors. Two different segments.
> specifically mentioned "bettors" - day traders/speculators, not long time investors
Forex is zero sum before fees and negative sum after. It’s distinct from capital markets. I wouldn’t extrapolate losses from FX.
It's the same loss percentage for stocks day trading. The loses do not come mainly from the zero sum/fees, they come from the lack of alpha.
> Depending on the source, only around 3% to 20% of day traders make money. But that 20% estimate probably has as much to do with the time period studied—the dotcom bubble. It's hard to know for sure, but it's probably fair to say that up to 95% of day traders lose money.
https://www.investopedia.com/articles/active-trading/053115/...
> same loss percentage for stocks day trading
The Investoperia article cites three sources for that claim, the second which claims one third [1].
One fifth to one third is more in line with what I expected. It’s also a range materially higher than 5%. Broadly speaking, you’ll see 90/10 to 95/5 in zero-sum markets like FX and derivatives, and 80/20 to 70/30 for capital markets.
[1] https://www.tandfonline.com/doi/abs/10.2469/faj.v59.n6.2578?...
All those other markets are vastly bigger in scale and trade in trillions on a daily basis so it's an irrelevant comparison. Also the expectation is that the majority of that 25% are insiders. So you're comparing catching fish in a barrel where 25% of the participants hooked the fish prior to you getting a turn vs fishing in the open ocean (so 5% is pretty good with additional voting rights/tax benefits).

People keep saying they provide the market with information, and that's the benefit of allowing the insider trading, but no one has pointed out how in any way society has benefitted from the insider trading instances so far...
The answer is pretty obvious, right? It doesn’t reliably deliver on that promise, and in the meantime they rake billions on unregulated gambling with near zero institutional exposure.
For sure I agree, but was of course severely downvoted every time I asked how anyone besides the inside trader benefit. Aaaand now I'm being downvoted again.
It provides information that's not accurate.
It's useful for things like elections, where though popular media might push one line of thought primarily, the markets will adjust to be closer to the reality. Pretty visible in the 2024 elections where if you followed mainstream media at all, you probably wouldn't realize the markets had Trump at a 60% chance to win just before the election.
But for so many things, there's just too many sources of insider info. Reality television especially, the last couple seasons of Survivor have been clearly leaked if you look at a prediction market. And since all of production knows, and obviously all the players know, someone tells their family members, and all of a sudden you have a few hundred people who know for sure who will win.
The 2024 prediction market had like several large bettors on the Trump side https://www.bloomberg.com/news/features/2024-10-25/polymarke.... The Harris side had no equivalent counter-whales. So the ~60% Trump prediction was not really reflecting reality, more-so individual conviction. A more retail-only market would likely have priced it closer to 52–55% Trump, which matches with what the pollsters and mainstream media said.
>It's useful for things like elections, where though popular media might push one line of thought primarily, the markets will adjust to be closer to the reality.

How did that number more greatly reflect reality than the polls?

But what exactly is the use of that? And as another example from the 2024 elections, every media outlet was pushing the validity of some stupid Iowa poll that only insiders even knew about, and was obviously just a random survivor that happened to get a few things right in a row. The prediction of a Harris landslide entirely flipped the odds in the prediction markets; if you had insider knowledge about that poll, you would have been able to make a fortune. If you had helped market that poll, you could have made a fortune.
The problem with prediction markets as predictors I think is that that they assume there will be a lot of insiders, rather than a very few. It gets confused with normal price discovery in a large, diverse and competitive market. Instead, prediction markets just match the (opinion) x (perceived trustworthiness) of the media landscape. If anything, insiders have a motivation to push the markets to be more inaccurate. They want to bet against them.
edit: but to restate my initial question - what's the use of polls that converge to the correct answer about 10 seconds before the actual votes come in? I asked the same thing when people were lusting over Nate Silver, and I still haven't gotten an answer. I understand using polls to guide your election expenditures; I do not understand the intense interest in them among spectators, or when the election is already mostly run.

> At first, it worked. Pederson turned about $2,000 into close to $8,000 by betting on daily snowfall totals in Detroit
I'm not a gambler, but when I consider it I think the worst thing that could happen to me would be to win a substantial but not life-changing amount of money. I think that's where most people get hooked. They get lucky once (or a few times), then get completely sucked in trying to replicate that success.
That particular set of circumstances is the ruin of many a lottery winner.
