Researchers say 152 crypto wallets won about $8 million betting on U.S.-linked military events, raising alarms that war plans may be leaking into a gambling market.
Story Highlights
- Analysis flagged 152 Polymarket wallets with unusually strong wins in military markets, totaling about $8 million.
- The flagged bets focused on large wagers on low-odds outcomes, a pattern consistent with privileged knowledge.
- A recent U.S. criminal case proves at least one trader used classified military information for profit.
- Polymarket says it bans insider trading and has referred suspicious wallets to authorities.
What the New Research Claims
On August 20, researchers reported that 152 Polymarket wallets made about $8 million profit from markets tied to U.S. military or defense events. Multiple outlets echoed the core numbers, citing an extremely high win rate on these wallets. The analysis leaned on a long-shot screen: large bets, at least $2,500, placed on outcomes priced at 35 percent or less, that later paid out at surprising rates. The clustered success suggests more than luck, according to summaries of the findings.
Reporters said some military-linked contracts showed win rates above fifty percent among the flagged set, far beyond normal chance for long-shot wagers. The accounts were not publicly identified. The research did not provide a direct link to named insiders or leak sources. Still, the pattern points to timely, confident trades placed before sensitive events became public. That timing is what troubles both security experts and market watchers who fear that a betting venue can become a channel for monetizing secrets.
Why This Hits a Nerve in Washington
An earlier criminal case shows the risk is real. In April, the Department of Justice charged an Army Master Sergeant with using classified information to profit on Polymarket, allegedly earning more than $400,000 from trades tied to military operations. That case gives a concrete example of the very behavior the August study suspects at scale. It also raises tougher questions: if one person did this, how many others tried, and did internal safeguards inside government actually work?
Members of Congress were already asking questions before the new report. In April, Representative Vindman demanded Polymarket turn over records on bets linked to U.S. actions in Venezuela and Iran. The letter cited concern that people could profit from war decisions and that market signals might even tip off foreign adversaries. Those worries cut across party lines: no one wants battle plans, covert strikes, or hostage rescues becoming an odds game for fast money.
What Polymarket Says It Is Doing
Polymarket says it does not allow insider trading and will identify those who try. The company says it monitors suspicious activity, has strict controls, and has referred dozens of wallets to authorities. It also says it updated its rules to bar trades based on stolen confidential information or illegal tips, and to block people who can influence an event from betting on it. Company leaders argue crypto rails make activity transparent and traceable for investigators.
Those steps show that platform cooperation can help. In public statements, Polymarket pointed to its role in referrals that led to insider-trading charges, reinforcing its claim that bad actors leave footprints on-chain. Still, the August findings suggest detection after the fact may not be enough when the subject is war. Once a strike happens, the money is already made, and the signal may have been broadcast to anyone watching the odds screen.
How to Read the Evidence Without the Hype
The new analysis is strong on patterns but stops short of proof. The research highlights odd success rates, size, and timing. It does not yet tie wallets to named people, military units, or a leak chain. The accounts could reflect coordinated groups or algorithms rather than many independent insiders. That gap matters for any legal case. Unusual wins on long-shot bets raise suspicion, but they are not, by themselves, a legal standard for insider trading.
Polymarket faces fresh insider-trading scrutiny after ACDC flagged 152 wallets that allegedly made $8M betting on U.S. military markets.
The wallets reportedly had a 97.2% win rate on long-shot defense bets, raising new concerns around prediction markets.

Broader studies of prediction markets find repeated pockets of “informed” trading across many topics, not only war. One Harvard-linked review screened thousands of markets and flagged many wallet-market pairs with higher-than-normal win rates, adding context for why these claims keep surfacing even when hard proof is rare. That backdrop suggests two truths can coexist: some traders are just skilled at reading open sources fast, and a smaller set may be exploiting nonpublic information.
Why This Matters Beyond Crypto
When people can profit from military action, trust erodes. Families with loved ones in uniform see a game that rewards whispers over duty. Taxpayers see a system where insiders get richer while they shoulder the risk. Both conservatives and liberals share a basic ask: stop leaks, punish cheats, and keep war decisions away from gamblers. Congress, regulators, and the Pentagon can start by tracing the flagged wallets, matching timestamps to events, and reporting what they find to the public.
