Polymarket Insider Trading Scandal And Prediction Market Legislation
Six newly created wallets profited roughly $1 million on Polymarket by betting that the United States would strike Iran before February 28, 2026 — with most positions opened just hours before explosions were reported in Tehran. Blockchain analytics firm Bubblemaps flagged the accounts after detecting a pattern that combined fresh funding, precise date selection, and near-perfect timing. The incident has reignited a broader political fight over whether prediction markets are information aggregators or vehicles for laundering classified intelligence into cash.
The Trade That Raised Alarms
The most striking position involved a wallet that converted roughly $61,000 into more than $493,000 by purchasing 560,680 “yes” shares at approximately $0.108 each on the contract “US strikes Iran by February 28, 2026?” Another account, “Planktonbets,” spread $173,907 in gains across seven separate contracts, suggesting repeated attempts to nail the exact strike date. “Dicedicedice” cleared $119,964 on a single bet, a 400% return. “Neodbs” posted the best percentage performance at 900%, turning $9,884 into roughly $89,000. Two further wallets added $66,436 and $45,556. All six have since liquidated completely.
A separate wallet, “Roeyha2026,” was funded just eleven hours before the bombing began. It wagered $50,000 that a US strike would occur before March 1 and netted nearly $100,000. Lookonchain published the on-chain data publicly, and the resulting debate among market analysts has been blunt: either someone got extraordinarily lucky, or classified information moved from a government channel to a crypto wallet.
Bubblemaps CEO Nicolas Vaiman acknowledged the limits of on-chain evidence. “It’s almost impossible to be 100% certain in these cases, but given the size of the bets, the freshly funded wallets, and the timing, it felt convincing enough to share,” he said. That caveat has not slowed the speculation. One widely shared social media post alleged that someone within Defense Secretary Pete Hegseth’s inner circle was leaking Department of War data.

Not everyone was positioned correctly. A trader identified as “anoin123” had spent months accumulating over $2 million in profits by consistently fading the strike probability. When US and Israeli forces carried out Operation Epic Fury on February 28, those contracts collapsed instantly. Blockchain data from Lookonchain shows the account swung from $2 million in gains to a $4.5 million deficit in under 24 hours, a total drawdown exceeding $6.5 million. It is a brutal reminder that conviction and capital are not the same thing as information.
Legislators Move Fast
The political response came quickly. Senator Chris Murphy announced plans on February 27 to introduce legislation banning prediction markets he described as “corrupt and destabilizing.” Congressman Ritchie Torres has separately advanced a more targeted bill that would prohibit federal employees and elected officials from trading on prediction market contracts tied to government actions.
Industry pushback was immediate. Kalshi co-founder Tarek Mansour pointed out that regulated domestic platforms are already prohibited by the CFTC from listing war, assassination, or terrorism contracts. Polymarket, the platform at the center of the scandal, operates offshore. Mansour’s argument is structurally sound: Murphy’s legislation would restrict compliant exchanges while doing little to reach the platforms where the alleged misconduct actually occurred.
A Pattern, Not an Anomaly
This is not an isolated incident. In January, a fresh wallet wagered $32,000 on Venezuelan President Nicolás Maduro’s removal at seven cents a share and collected more than $400,000 before the announcement went public. Israeli prosecutors have already charged an IDF reservist and a civilian for allegedly using classified military intelligence to trade Polymarket contracts tied to Israel’s June 2025 strikes on Iran.
The aggregate betting volume across all “US strikes Iran” contracts exceeded $529 million since December 2025. The February 28 contract alone drew roughly $90 million. When markets that large exist around events controlled by a small number of decision-makers, the incentive to exploit information asymmetry is obvious. The question regulators cannot yet answer is how to close that gap without dismantling the legitimate price-discovery function that makes these platforms worth defending in the first place.
