Pentagon Warns Military Bets Can Expose Secret Operations

The Pentagon prediction market directive warns of leaks but leaves war betting, platform incentives and Washington's military power largely unchallenged.

On October 20, Defense Secretary Pete Hegseth warned US military personnel against using secret information to bet on military operations. A wager on a strike date, he said, might alert an adversary before the military acted. It was an admission from the institution planning those strikes: confidential knowledge can become private wealth and a public signal.

The memorandum, reported October 22, names Polymarket and Kalshi. It covers classified and other nonpublic information, even trades placed through another person. But it neither bans every wager on war nor creates a new offence. It leaves the market for military outcomes largely untouched.

Hegseth has identified a danger to Pentagon secrecy while leaving the wider trade largely intact. That is too narrow a definition of accountability for a business built around the decisions of a military superpower.

The Pentagon's Concern Begins With Its Own Secrecy

Hegseth warns that foreign intelligence services can read trading patterns for clues about targets and timing. He also warns that personal bets can distort military judgment. A logistician betting on a strike date or an analyst trading on an operational result has a financial stake in decisions they may influence. Those conflicts were apparent long before October.

Federal restrictions already barred personnel from exploiting confidential information for gain. The memo names prediction markets and threatens discipline or prosecution under existing law. It does not decide whether military-outcome contracts should exist, what screening platforms owe the public, or how privileged outsiders are covered.

The Washington Post reported that the memo left unclear its application to contractors with classified access. In a defence system reliant on contractors and intelligence partners, that gap demands an answer. The Pentagon cannot call leaks a threat while leaving the scope of its response unclear.

Hegseth centres American secrecy, combat effectiveness and troop safety. But the people near the targets, the sovereignty of countries subjected to US force and the public asked to accept these operations also have interests. Making a raid harder for an adversary to anticipate does not answer those questions.

A Soldier's Alleged Profit Is Not the Whole Scandal

The most prominent case arose from the January US operation that captured Venezuelan President Nicolás Maduro. In April, federal prosecutors charged Army Master Sgt. Gannon Ken Van Dyke, alleging that he used information obtained through his participation in planning and executing the mission to trade before the operation became public.

The CFTC complaint alleges that he operated the Polymarket account known as Burdensome-Mix and spent approximately $32,538 on the principal Maduro contract, generating more than $404,000 in profit. Van Dyke has pleaded not guilty. His lawyers challenged the legal basis of the charges at an October 7 hearing, and the judge did not rule at that hearing. His alleged use of classified information remains an accusation, not a conviction.

If prosecutors establish their case, it would be a grave abuse of military access. But focusing only on the accused soldier excuses too many others. The American state authorized the operation, a private platform made its outcome tradable and regulators have yet to resolve the market that grew around such events. Who placed the bet is only part of the story.

Nor is there evidence that Van Dyke’s alleged trades actually alerted Venezuelan authorities. The Pentagon is describing a danger that trading can create. It does not need a proven intelligence compromise to justify examining the incentives built into these markets.

The Platforms Sell the Opportunity to Speculate

Polymarket said it flagged suspicious activity related to the Maduro trades, passed information to authorities and cooperated with the Justice Department. The department acknowledged that cooperation. Reporting a suspected abuse is preferable to ignoring it. It does not answer why contracts on the removal of a foreign president were available for purchase before a military operation, or why detection after trading can be presented as an adequate safeguard.

Transaction transparency cannot identify the person behind every wallet or their access to classified briefings. A price can reflect public analysis, reckless speculation, manipulation or privileged information; a chart does not distinguish among them. When an informed trader moves a market, publicity may spread the information rather than contain it.

Polymarket and Kalshi are not interchangeable, and Hegseth naming both does not mean both listed the same military contracts. But their shared business proposition is that more outcomes can be turned into financial positions. AP reported that Kalshi disciplined congressional candidates who bet on their own elections. Those were different contracts and different people, but the underlying incentive problem was similar: people with privileged access or direct influence over an event should not hold private financial stakes in its result.

The firms have obligations beyond helping prosecutors identify suspicious winners. They decide which events to turn into markets. A company cannot claim to be an innocent observer of the risks created by contracts it chooses to offer.

Speculators Can Amplify a Leak Without Knowing Its Source

The problem is larger than a handful of spectacular wagers. In August, the Anti-Corruption Data Collective identified 152 Polymarket wallets in military-related markets that matched its pattern for potentially informed, highly successful long-shot traders. The accounts had collectively earned more than $8 million. The findings are indicators warranting investigation, not proof that all 152 wallet holders were military insiders or acted unlawfully.

Researchers also found that larger traders and automated accounts appeared to follow some of those positions. That creates an additional danger. The first bettor need not broadcast a military briefing directly. Other speculators can chase a move, increase its visibility and turn one possible informational advantage into a signal observed by thousands of people, including foreign intelligence services.

Not every trader is an insider. But buyers can still be criticized for treating war, assassination threats and forced political removals as opportunities for a return. Speculation places private financial stakes on events whose costs fall on people who never agreed to the wager.

Regulators Already Knew the Problem

The CFTC is not arriving at these questions for the first time. In June 2026, it proposed rules for determining whether event contracts involving war, terrorism, assassination, gaming or unlawful conduct violate the public interest. Its proposal recognized national-security risks, information leakage and incentives to profit from violence. The regulator therefore has a documented understanding of the dangers Hegseth is now describing.

Its Federal Register proposal even judged war-related contracts highly likely to fail a public-interest test. Yet the proposed contract-by-contract review concerns event contracts listed or cleared through CFTC-registered entities, not the unregistered platform on which the CFTC says Van Dyke allegedly traded. Regulators and lawmakers must answer how the same dangers will be addressed beyond that registered-market framework, instead of leaving them to case-by-case enforcement after the fact. A prosecution months later cannot withdraw a price signal already broadcast.

There is also reason to demand scrutiny of enforcement itself. On October 22, Reuters reported that the CFTC was investigating suspicious trading around the US war in Iran, while acknowledging questions about surveillance and enforcement inside the agency. The regulator said its investigation was ongoing. Neither a pending investigation nor a proposed rule should be mistaken for proof that public safeguards are working.

Washington Wages the Wars Others Bet On

The Pentagon’s account makes the insider wager sound like a distraction from a legitimate military mission. But the market exists because political and military leaders can make consequential decisions in secrecy: whether to launch an attack, remove a leader or escalate a confrontation. People with access to those decisions possess an advantage not available to the people who may be bombed, displaced or governed under the consequences.

That hierarchy does not begin with Polymarket. It begins with the concentration of military power. The platforms put a direct price on it, the speculators chase the price and the regulator attempts to police conduct at the edges. The Pentagon’s new order is concerned that the transaction could give enemies too much warning. It says much less about the public kept in the dark or the foreign population whose future becomes the subject of a trade.

Calling the outcome a prediction does not remove its political character. A contract can settle cleanly on a date while the raid, its legal basis and its human costs remain deeply contested. The distinction between making a correct prediction and endorsing a military intervention does not absolve a business of responsibility for choosing violence as an object of speculation.

An Order Is Not Accountability

An enforceable ban on insider trading is necessary. It is not enough. The Pentagon should account for access controls, contractors and enforcement within its own institutions. Market operators should explain why they list contracts where the strongest information may come from secret state action. The CFTC and lawmakers should confront whether some bets on war and political violence should be tradable at all, rather than limiting their response to investigations after payouts occur.

Hegseth’s warning leaves much intact. Washington can plan operations in secret, businesses can develop markets around political events, and traders can hunt informational advantages. The clearest prohibition targets the government employee who tries to cash in on knowledge acquired at work.

If Washington objects only when the bettor threatens operational secrecy, it has not resolved the public-interest problem. It has defended the state’s monopoly over knowledge of its own use of force while leaving the conversion of that force into a market largely unquestioned. The people who bear the consequences of war deserve more than an assurance that its planners will not gamble on the timing.
