Soldier won $410K in Polymarket bets on timing of Maduro capture, US alleges

CNBC wrote that when “a reporter noted there have been other allegations of insider trading on prediction markets about the Iran war, Trump said, ‘You know the whole world, unfortunately, has become somewhat of a casino.’” Trump also said that he is “not happy with any of that stuff.”

….so you’ll be refunding everyone who lost money on your stupid meme coins, right?

Short answer is it isn't. It would have been nice if the article put "insider trading" in quotes. I get they were using it illustratively but there is no prediction market specific insider trading laws. He was charged with illegally using/disclosing classified material.

Misuse of classified materials is illegal even outside of prediction market. More than one person has disclosed classified materials in order to win arguments on warthunder (a video game). That is just as illegal although dumber.

i'm pretty ok with prediction markets in principle, but this is starting to move my needle away. i guess i was naive to assume that people wouldn't try to bet (and essentially leak) national security information for profit.

Polymarket user magamyman made $515k betting on the initial US strike on Iran, 71 minutes before it happened:

And in the commodities markets:

EDIT to not place blame on commenter

Anyway, if there's money to be made, someone will try to make it. Especially easy money like this requiring practically zero effort.

It seems to me that in addition to the insider trading/fraud financial aspects of this story, there's also a classified information/national security issue. . .

If people notice that that a specific account is making very specific bets about military action, and they notice that account usually wins those bets, then looking at the bets that account makes might tell you advance information about secret military operations. . .

'to have any utility requires "insider trading"'

You are conflating public and private information.

What makes it an efficient market is the public information. The participants who are better at making decisions on partial information produce more accurate predictions.

Decisions made on private information are a market failure and are inefficient.
Wasting a large proportion of the nation's resources on financial engineering (aka glorified gambling) is a big part of the reason why the US is falling behind China in the real world.

More on topic, anyone who bets on unregulated markets like this that are obviously vulnerable to insider trading is an idiot and deserves all the losses they're hopefully getting.
ALSO: Traders on these markets are starting to try to corrupt real world things like journalism and government officials.

I came across this story a few weeks back, about gamblers on Polymarket trying to threaten/bribe an Israeli journalist to change their reporting so that they could win their bets.

I'm not even going to bother commenting on what a scumbag Trump is.

More interesting here is an ongoing major, unplanned, undebated expansion of government. Consider for a moment the purpose of regulation of the financial markets. Initially they were not meaningfully regulated. Cornering the market was an obvious goal of all cutthroat merchants and early industrialists. It was only with successive disasters that had wide social impact the 1933 act came along trying to (and by and large succeeding) seriously regulate these matters.

I bring this up because human law reacts to social needs, not theoretical, mathematical law.

I think explaining away responses to the conduct that caused the Great Depression are more than "social needs." They are economic needs, too.

What need is actually served by regulating prediction markets? I feel similarly about regulating casinos (or relatively benign drugs like pot and alcohol). Crypto, too. If we had the widespread drama that ensued in the Great Depression, toothy laws similar to 1933 would obviously be warranted. But, at least so far, we have not in the case of prediction markets and crypto generally. The War on Drugs really hurt the country, but you can hardly blame drugs for that. We did that to ourselves with the law.

Need 1 is that these bets reveal plans. The size and timing indicates inside information; interested parties could watch the markets for indicators that, for example, they are going to be attacked, and respond accordingly. That endangers actions and people.

Need 2 is that the people involved have huge financial incentives to ensure particular outcomes. In this case he bet on success, but it doesn't have to go that way. In sports betting, there are numerous examples of people throwing games because of those financial incentives. If it's not just a game but people's actual lives and livelihoods riding on the outcome, then gambling significantly decreases the chance of the best outcome.

What has happened is a few fools have gambled away their money or ruined their lives chasing other addictions. If you think law can really stop that, I got a bridge to sell you. The best law can do is slow down the chaos and keep it from being an all-consuming epidemic as in the Great Depression (and earlier episodes, especially the 1890s).

Laws don't stop crime. We have laws against murder and theft, and they have failed to stop murders and thefts from occurring. But no one is stupid enough to claim that means we should get rid of those laws.

Laws shift the risk profile against a given activity. They therefore reduce the desirability of engaging in that activity, and reduce the frequency. They make examples of violators to discourage future violations. They take violators out of the system (i.e., imprison them) to prevent repeats.

Arguing that our inability to achieve 100% of anything means that we should take no action is a sure way to achieve nothing in your life, and the sooner you set aside that way of looking at the world, the better off you will be.

We didn't have any debate as a society on whether prediction markets should be regulated. We just watched government assert that people betting inside information is illegal. I don't think it is or should be -- either prediction markets are illegal casinos (and sure, maybe they're completely illegal then), or really, I don't care much about what happens on them. I feel similarly on crypto. I feel similarly about relatively benign drugs, and less so about catastrophic ones like crack or fentanyl.

Crypto and prediction markets should probably be banned entirely, as China did with crypto (to really no one's harm). But short of that? Fools will find a way to lose their money. I certainly don't want to pay taxes to help fools drink poison more safely. That's a pointless exercise, if it is not a national emergency.

as an aside, anyone interested in the topic of insider trading should subscribe to Matt Levine on Bloomberg. You don't have to pay to do that. He humorously teaches what amounts to a postgrad class in the lore and legal tussles of insider trading, among other things.

Casinos have a lot of issues, and certainly contribute to destroying the lives of gambling addicts, but they don't provide incentives to screw up other things. Winning or losing a poker hand doesn't get soldiers killed, it doesn't damage the economy. So, yes, a prediction market is gambling, but it also does additional harm.

Crypto, of course, also does tons of additional harm, and should be evaluated in the same light.

If I were a betting man, I’d be on poly market betting Trump would respect the grift with a stern don’t do it again and pardon him. But maybe the man only does things that benefit him.
What are the odds that other senior administration officials were on the opposite side of this wager?

Not every use of words needs to be legally precise. It's trading on a prediction market based on information that is secret, i.e., inside information. The underlying principle here is the same as insider trading. Whether it meets the legal definition is of questionable relevance.

That said, if you actually read the CFTC filing:

B. Section 4c(a)(3)-(4) of the Commodity Exchange Act
17. The Act also seeks to deter and prevent the misuse of nonpublic government information to trade in commodities and derivatives markets for personal gain. Toward that end, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 expanded the Act’s prohibitions on insider trading to apply not only to the misuse of information by CFTC personnel, self-regulatory organizations, and exchanges, but also to the misuse of nonpublic government information by any person. In seeking and implementing those amendments, codified in Section 4c(a)(3)-(4) of the Act, Congress affirmed its intent to ban government employees and agents from insider trading using nonpublic government information, and all persons from insider trading using nonpublic information misappropriated from a government source.


It may actually meet the legal definition, too.

Funny how emphasis goes in the newstitles...

Most play on the "Soldier charged for betting" tune, then a few "...using classified info". Kudos to Ars for stating this correctly...

I find the idiocy of taking the risk of leaking info that can get your people killed by taking bets that make hostile entities' ability to put two and two together to be orders of magnitude higher than the betting itself.

Genuinely curious - can this even qualify as insider trading?
The guy used information about an upcoming military action, but no result of that action was guaranteed.

Are boxers that are overwhelmingly favorites prohibited from betting on themselves winning? This stuff has always been quite foggy to me. An imaginary boxer shouldn't be prohibited from betting on therself just because they feel in great shape, would they?
As others have pointed out this isn't technically insider trading because he's not trading regulated securities. However, I just want to add that insider trading doesn't require you to have information about something that's guaranteed to happen. It just requires you to use information that's not publicly available. If your company is about to be bought at a significant premium and you find out about it before it's publicly announced, you can't buy a bunch of stock. Even if the deal falls through, you'd still be guilty of insider trading.

As for the boxing part, I think gambling on one's own matches is prohibited in any sport by the regulating body. It could also be illegal, but that will depend on the laws of the venue and athletes.

That's what surprised me. How is the DOJ charging and active duty military member with anything? Isn't he subject to the Uniformed Code of Military Justice (UCMJ) first? After his court martial and sentencing to a military prison/work camp, THEN the DOJ can have him.

I don't think this is right. He was charged with commodities fraud and sued by the CFTC, which is exactly how you'd expect an insider trading case to be charged. US insider trading law isn't really based on fairness, it's based on theft. That's why the charges take care to point out that he had "a duty of trust and confidence to maintain the confidentiality" of the info. You're allowed to trade commodities based on your own information (and we've decided to regulate these things as commodities futures for some reason). It would be absurd if an oil refinery wasn't allowed to buy oil futures based because they knew how much oil they planned to process next month, but it's not ok for the refinery's employees to use their employer's private plans to front-run them because they're under an NDA.

So yes he's in trouble for revealing classified info, which is a crime by itself, but he was also charged with insider trading because that information belonged to the government and he had a duty not to reveal it by trading. There's no charge called "insider trading," it's considered a subtype of commodities or securities fraud.

I wonder if he might be charged both by DoJ and Court Martial?

DoJ might be charging the civilian crimes he's alleged to have committed while DoD might prosecute violations of UCMJ? The same underlying facts might violate both military and civiilian law?

I've seen stories before of soldiers prosecuted under civilian law for crimes that were fundamentally civilian in nature, even though they happened to be members of the military. In this case, the alleged acts seem like they could violate both sets of laws?

What does a prediction market do that causes additional harm? Or crypto, frankly? It causes the people who took the wrong side of a bet (or tried to not be the greater fool) to lose money, but that's exactly what happens in a casino, too. So what else is going on that I don't see?

n.b. The reason stock market insider trading is different is the ability when manipulating markets to cause a stampede and wipe out whole swathes of totally unrelated people, but that isn't remotely true about bets in a prediction market, or a racetrack, or a casino.
The current prediction markets allow betting on almost anything and so create a huge surface area for manipulation. That manipulation is concerning as, to use the Israeli journalist story mentioned by an earlier commentator as an example, it encourages threats or violence against others to swing the bet.

Say I had a friend in the Israeli army, I might pay him to fire a shell into Lebanon, after claiming to come under sniper fire, while setting up a bet “Isreal to strike Lebanon on day X.” $50,000 for him, $200,000 for me. Shame about the people whose house he hit.

Traditional betting markets could have the same problem and prediction markets could be run more responsibly, so it’s not the prediction market concept that’s the problem: it’s the implementation.

prediction markets in principle aren't any different than the stock market or a futures market.

asking people to put a price on the information they know or on their expectations is a useful signal, either in markets, or societally.
Buying a stock is a absolutely not the same thing as gambling on a prediction market.

Pretty sure both of you in that example would be prosecutable for conspiracy to commit murder, so the existing laws cover the specific scenario you imagine just fine. The laws the AGs are trying to use aren't remotely related to such scenarios.
The issue isn't that there isn't a law to cover that crime. It's that it incentivizes committing that crime.

any details on how they found him?
my understanding is that access to Poly is very restricted inside the US (without a VPN?) and transactions are typically linked to crypto accounts?

I know such things are not 100% private, but he probably jumped through a few hoops to hide his identity
Polymarket came back to the US in late 2025 (guess why).

In theory his "bet" is closer to what Polymarket and Kalshi claim they are for. He made a "bet" on whether his life could be at risk, kind of like shorting the market.

Somewhere in China a spy is sitting at his desk, wondering why he spent long nights day after day for 30 years learning how to predict US military operations and decisions, when now you just need to look for suspicious bets on a public betting market.

And if you really want to get funky, do some light hacking to tie the prediction market IDs to real people. Figure out who the insiders are so when you see them bet, you've got gold-plated intel.

Everyone I know in the military/DoD and adjacent industries immediately knew it was an insider, someone with clearance and eyes on shit they should not be talking about, making those bets. It's not at all surprising.
And he did it with +/- 2 years left before getting his 20. Looks like he got nabbed by the DOJ and not military police, but I'd expect he'll be drummed out of the Army prior to getting any retirement benefits. Good riddance to bad rubbish.

Haven't we (as humans) been through this whole game a few times already?

Like remembering back to history classes, I thought that when insurance as a financial tool was first introduced, people quickly turned it into a gambling thing. Doing things like taking out insurance policies on the outcome of sports, or on when other people would die. Which quickly turned into society destroying rot as people tried to increase the odds of their insurance bet winning. Resulting in insurance becoming regulated to prevent its use as a gambling loophole.
