The question answers itself.
Also -- hedging is generally not done based on material non-public information, but rather to guard against known risks. Joe the farmer sells a bunch of wheat futures when he plants his wheat, not because he thinks the price will go down, but rather because if it does he goes bankrupt and he'd prefer to accept a known rate-of-return now.
But it’s more accurate to say participants can trade on lawfully obtained material nonpublic information absent some independent duty not to use it, which is much narrower than saying insider trading is generally legal.
If you make a hedging trade while having material knowledge that you withhold from the counterparty… well, that sounds like it could be edging towards fraud. Like taking out life insurance while hiding a medical condition.
But sure, it’s not against the law to do business with a sucker, so there’s degrees here.
Not that this excuses some of the absurd stuff that goes on on the online betting platforms...

They don't have much to say about Kalshi other than "unlike real mainstream journalism, there’s no accountability". Which isn't saying much, because nobody is claiming prediction markets are a type of journalism.
James Surowiecki wrote an entire book essentially saying otherwise.
Claiming that something is a better way to learn about the world is NOT the same as claiming it is using a specific method, or part of a specific tradition.
I’m open to being convinced, but if you’re claiming mainstream media has no accountability, I think you need to substantiate that.
I realize there are information bubbles on the internet where this is accepted as truth, but unexamined. Nonsense is everywhere on the internet. I’d be curious how you’d substantiate this.

It's always corrosive to society in a way other vices really aren't. Money is a massive influence and incentive, and in gambling you can artificially increase the possible incentive size with long shot bets.
The best part of how gambling makes everything shit is that gambling addicts will ruin the sanctity of everything that claims authenticity for just a few actual dollars of "profit", after you ignore all the money they've lost by betting, which addicts tend to do.
Assholes who insist betting on things are the best and totally great for the world somehow will harm a sports event that ten thousand people have paid a hundred dollars to enjoy just to earn a hundred bucks themselves.

I think most people have experienced what Michael Chrichton called Gel Mann Amnesia - the idea that newspapers feel accurate except about topics you know about.
Whenever I read about topics I know about: such as my employer, a political topic I am particular familiar with, etc - the reporting is usually off in what MC called a "wet streets cause rain" kind of way.
I haven't seen any accountability for this kind of reporting. If a newspaper wrote that someone was born in 1980 but it was actually 1985 they may correct that but the broader theme of articles being inherently misleading to reality is rampant and I suspect significantly worse than when MC conceptualized this problem.
That's to say I am not sure there's a practical standard to which a random times writer is held that kalshi isn't to. If anything I think kalshi is more clearly presented as "a bet" vs "the truth" so I don't understand the meat of the grievance.
In 2018, the US Supreme Court said the federal law preventing it was illegal.
https://en.wikipedia.org/wiki/Murphy_v._National_Collegiate_...
It was banned by the federal government in 1992 by an act of Congress (with bipartisan consensus and signed into law by a Republican president). The supreme court vote overturning it was also 7-2, with 2 of those 7 appointed by a Democrat president.
Not exactly. The law was weird, and that's why it was overturned. It didn't make sports betting illegal federally, instead it prevented states from "authorizing" it, which the petitioners argued was an unconstitutional intrusion into the lawmaking ability of states in that it prevented them from repealing laws against sports betting that they had previously passed.
The full ruling is at https://www.supremecourt.gov/opinions/17pdf/16-476_dbfi.pdf, and the last paragraph sums it up: "Congress can regulate sports gambling directly, but if it elects not to do so, each State is free to act on its own".
The SCOTUS ruling didn't legalize sports betting; states chose to do that themselves once they were no longer prevented from doing so. Congress could ban it nationwide today, and probably they should.
Trump Jr. just pumped 300 million into Polymarket and also has a stake in Kalshi so, i'm not sure who thinks the DOJ will really do anything. this is fentanyl on the phone but there will have to be a few examples like some low-levels House members or state senators alongside sports casualites

To me, the rules on how large a media conglomerate could get being changed in favor of allowing the conglomerate to grow even larger did some heavy lifting. Journalism publishers no longer have to compete since their all owned by the same limited number of owners.

Why should I pay for someone else's bus route?
Despite my libertarian leanings I have to acknowledge that sports betting is a disaster for people with low impulse control, and while in theory prediction markets are useful for aggregating knowledge, in reality they've been taken over by degenerate gamblers and fraudsters.
Unions are for improving worker conditions such as getting the right pay, and right working environment.
They want to "run" the company themselves. Some might argue they are for keeping their current working env without Kalshi.
They are not the ones who has to bear the financial responsibilities of the company. They can shove it and just move on.
When the company does poorly, who ends up hurting more? Is it the workers that get laid off, the executives that get another bonus, or the owner that remains a billionaire?
> A partnership between The Times (for The Athletic) and Kalshi would also provide validation that their prediction market data should be taken seriously as an indicator of the future. Facts prove otherwise.
They could have objected to the partnership on any number of valid grounds, like the fact that predicting the outcome of sporting events provides no valid benefit and can only ever be gambling, or that the integration is probably going to be pretty lame and provide no benefit to the reader.
Instead, they felt compelled to make a trivially false claim, the claim that prediction markets do not accurately predict the future. It's trivial to prove that this claim is false, because if it were true, it would be very easy for anyone to make a huge amount of money on prediction markets.
It's even more telling why they made this claim, to avoid "providing validation". Not because of any harms caused by sports gambling addiction, but because it could provide a tiny piece of political ammunition to a product that has been slotted into the opposing political tribe. Reading this statement, one gets the impression that they would be completely OK with sports gambling on The Athletic, as long as it was provided by a more traditional casino-style bookie operation.
I'm guessing that anyone in the room when this statement was written who even brought up the question of the facts could be safely sidelined and ostracized by the union as being insufficiently loyal to their political position.
Not only are you seeing the advertisements for these platforms and their betting apps, you're having a coordinated focus on actively pushing it in a myriad of other ways as well.
Modern gambling isn't you talking to a bookie and putting down $100 on your favorite team. That should still be legal. Phone apps which learn your behavior, your favorite teams, the offers you are likely to accept, the time of day that you're most likely to make a bet, etc etc and use that to barrage you with notifications, "free" plays, high paying parlays with horrible odds, should not be.
Society bears the downsides of gambling and gambling addiction, while the casinos gather all of the upside.

> NHS gambling clinics have experienced a rise of 130% in referrals in a year, leading to a large increase in the number of support locations.
Seems like the UK is also experiencing a large increase in problems from modern gambling systems.
The problem with the stock market is when there aren't enough new companies going public to soak up the spigot of all the capital that people want to invest, leading average P/E ratios to increase over time. There is too much money chasing too few earnings. When the underlying fundamentals don't match up, then all that investors are doing is speculating that someone else will be the bigger fool and buy from them at an even more unreasonable price - and that is a gamble.
I'm not intimately familiar with prediction markets (I avoid gambling), but can you explain how this is the case? If the market unpredictably incorrect, then shouldn't it be difficult / impossible to predict precisely which bets will be wrong in a way that would allow you to profit from them?
Ultimately isn't it the case that all they're doing (at least from a prediction point of view) is aggregating (better or worse informed) guesses? Excepting outright corruption / insider trading of course. This might tell you a great deal about what the set of users of a given prediction market expect as an outcome for a given prediction, but it doesn't tell you anything about the future itself. Any more than the stock market (fails to) tell us to pull out money out the day before a crash.
Now, say that you somehow knew that this coin wasn't a fair coin, and instead was weighted 55% to fall on heads, 45% tails. Then, you would be happy buying these contracts for 50 cents -- given the contract pays out $1 if the coin lands on heads, and you know there's a 55% chance of heads, the expected price for the contract is 55 cents, and you make 5 cents in expectancy.
So, if you had information about the "fair value" of this contract, telling you that the price should be 55 cents, you'd be incentivized to buy the contract at prices below 55 cents. If the contract was trading at any price other than 55 cents, then, from your perspective, the price would be incorrect. And if the price is incorrect, then you'd be able to make money trading: buying for prices below 55 cents and selling at prices above 55 cents. And finally, as a result of your trading, you'd provide one-sided demand to the market, pushing the price closer to the actual correct price.
From this simple mechanism, wherein everyone who has information is incentivized to make money on their information by trading, prices start getting pushed to accurately reflect the aggregate of the information that everyone possesses! So in markets, there is a profit incentive to provide information, and this makes prices more accurate.
Finally, I think a common misconception is that prediction markets are sometimes wrong, as events priced at low probabilities sometimes happen. For example, in the 2024 election, Trump was trading at probabilities below 50%, but he still won! However, this is conflating present information about the future with future results. Given the earlier example about the biased 55% coin -- before we flip the coin, the best thing we can possibly say about the future really just is that there's a 55% chance of heads and 45% chance of tails. If we then flip the coin and it lands on tails, that doesn't mean we were incorrect -- it was just the best statement about the future that we could have possibly made.
Prediction markets -- or really any price system -- aggregate the best available information about the future. If you can confidently state that they are wrong -- that their best available information about the future is inaccurate -- then you should be trading and making money.
Does that clear things up a bit for you? It's a longer response, but I think it might address some of the confusion that you (or anyone else) might have regarding what people actually mean when they say that these prices predict the future.
Isn’t that what’s actually happening though? Traders are making real money from bad predictions?

Even taking your nitpick a little bit seriously, behold:
> Retail prediction market traders pick winners 51.3% of the time yet lose money; automated traders achieve coin-flip accuracy yet earn $133 million.
The entire enterprise exists to move money from gamblers to companies. The externalities (suicide, social degradation) of this transaction is bourne by society.
Your whole comment misses the point of the sport. It is not effective to look for the most accurate or rhetorically tested point, the goal is to rally as large a group around a point that dosent make them look like hypocrites, or materially clashes with how they present their identity in other parts of their lives.
This point being mealy mouthed is by design.

> Now, say that you somehow knew that this coin wasn't a fair coin
So insider trading?
I appreciate the verbose response, but the original comment implied that prediction markets literally predict the future... Which as you've stated they do not.
I'd contest the idea that they aggregate the best information too. Since they seem highly amenable to manipulation, the metagame of convincing the market that a given future is more or less likely seems more profitable.
Confidently stating a given markets prediction is wrong would involve accurately predicting the future... If one could do that consistently, a prediction market would be unnecessary to accruing wealth and power.
I read mainstream news, but I don't know what you're referring to.
It's not like they are perfect, but I do see accountability when they screw up.
> Kalshi handed him equity worth roughly $300,000 when he joined as a strategic adviser in early 2025. ... Kalshi granted him the stake when the company was valued at under $2 billion — less than a tenth of its $22 billion valuation in a funding round last month ...
Um, how does a $300K stake at an "under $2 billion" valuation become "worth billions" with a 10-50x valuation increase?
(Disclaimer: I'm not defending the Trump family in any way, the administration has been absurdly and blatantly corrupt.)
Open the watchduty app and start looking into how many fires are currently arson suspected/apprehended and how this is the largest national wildfire year we've ever had.
The Dick and Cleetus methheads doing this stuff aren't the brightest and most well informed tech risk takers out there. Most of them will get caught and never get a dime, who the hell knows how why or else they're causing fires, the FBI isn't investigating anyone. They don't tell us WHY an arson occurred. Who knows how many of these apps exist in other markets, etc. The last global wildfire article I saw said either 86 or 96 arsons were arrested. I can't remember if it was France or in Africa.
This is THE strangest wildfire year anyone has had and the news is nowhere.

Even if that is true, UK gambling really is not a force for good, quite the opposite. And becoming worse as it moves from a betting shop on the high street into a betting app in a persons pocket.
As a tangent, it reminds me a bit of cryptocurrency: in the earliest days the interested parties have a mix of intellectual (can it be done? How can it be done?) and some idealistic (this technology will have utility, like reducing spam or libertarianism for crypto, or giving us a more accurate and precise understanding of the world for prediction markets) values. Of course, as both are directly financial, the third value is that one stands to get rich off of the technology. This third value might be adequately communally suppressed in the beginning, but the force of money gradually makes this third value the only one that matters, and both technologies become net-negatives on humanity.
Easiest way to know its just valueless
Might be something the populace is just too dumb to have - the people seem to overwhelmingly prefer their events to be pretty much games of chance (BTC price up/down at 15 minute intervals) or sports.
I figure Kalshi and Polymarket for dead before too long, if only because the "traditional" sportsbooks seem to have much better "government relations".
Sounds like the enlightened citizens of the UK aren't either?
> Health service figures show that from April to September 2024, 1,914 people were treated at NHS gambling clinics. This compares to the previous financial year when a total of 1,389 patients were cared for. In 2022-23 this number was 1,013, and in 2020-21 it was 775 patients.
I get that you're probably trying to make a point that it's bad for everyone in general, but the US is on a completely different level of societal corruption from all of this.
I guess I should just stick to really deep thoughts like "America is not the UK and its citizens are not capable of regulating themselves in the face of this sort of exploitation", with absolutely nothing other than vibes that it's true. Because of course Americans are dumb.

Let's for a moment say you're right, and prediction markets do have a flaw (that if someone wants to spend a lot of money making an outcome look more/less likely), that's an imperfection vs the many biases in other information sources.
tl;dr prediction markets financially penalise providing misleading information, whereas traditional media profit from misleading information
Short term trading, however ...
Maybe we should just put limits on how short one can own a stock (?)
But do I want the prices to be as efficient as possible?
But i think one of the prediction markets more important uses is to enable insider trading for the current administration.
All of the above is completely independent from what Congress can or cannot do.
Sophisticated investors would never be on the other side of the trade. Add to that bigger spreads and unsophisticated market participants get fleeced. As they wouldn't want to get fleeced they would hire an intermediary to do trades for them - a stock broker who again charges commission.
We already had that: spreads were bigger, prices were less efficient. The main victims were retail/naive investors and the main beneficiaries would be big institutions, brokers and sophisticated investors.
Current system benefits:
-retail/unsophisticated investors
-vanishingly small group of the best/fastest/most sophisticated traders
Who lost:
-big institutions, banks, stock brokers
-investing wannabes who no longer get access to easy money from retail/naive buyers
You seem to assume there is a pool of sharks that prey on pure souls without fast connection. It's not the case at all. Most HFTs lose money without exchange incentives which are provided because exchanges understand liquidity and low spreads are good for other participants. The pool of people who make money out of spreads/inefficient prices is way lower than it used to be as well.
The best possible world would have efficient prices every nano-second coming from god himself. Having a group of very sophisticated market makers is the second best we can have - at least if you care about normal investors who don't have resources to process all the information themselves.
Making a sudden event that happened on the other side of the world reflect in the local market price at almost the speed of light is far more meaningful work than going around shooting dark-skinned people.
Imagine news broke that makes a company worth 15% less. Naive investors isn't aware of it and makes their bid on the market. They look at a recent price, make some offer and buys the shares now worth 15% less while bankers who were able to process the information just made a killing. This is even worse in "slow exchanges" where participants need to come-up with bid price themselves because recent transaction price is not a relevant indicator of fair value.
Also considering that these traders will use their $100k in ways that my $1 will become worth even less. For example by buying all the housing in my neighborhood and thereby increasing my rent.
Electronic trading doesn't need to go away. The trade itself might take some time instead of being functionally instant, but that's fine.
