Polymarket Iran War Bets Hit $529 Million as Insider Trading Allegations Mount
$529 Million Wagered on When Bombs Would Fall
As US and Israeli airstrikes hit Iran on February 28, 2026, traders on Polymarket — the crypto prediction platform — were cashing in. The “US strikes Iran by...?” contract, live since December 22, 2025, accumulated $529 million in total trading volume, making it one of the largest single markets Polymarket has ever hosted. The February 28 date alone attracted $89.6 million in volume.
Anyone who bought “yes” shares on the specific strike date before bombs fell collected on a binary bet about when the US military would attack another country. The shares were trading at just 10-18 cents — implying a 10-18% probability — when the suspicious purchases were made.
Six Accounts, $1.2 Million in Suspicious Profits
Blockchain analytics firm Bubblemaps identified six wallets that collectively netted approximately $1.2 million in profit by betting on a US strike on Iran by February 28. All six accounts were created in February 2026. Most wallets were funded within 24 hours of the attack. They bet specifically on the February 28 contract, purchased “yes” shares hours before the military operation, and had no other activity.
The largest single wallet turned roughly $61,000 into over $493,000 in profit — an 812% return — by purchasing 560,680 “yes” shares at $0.108 each. All six wallets now show $0 in positions, indicating they fully exited after collecting.
Israel Already Making Arrests
This isn’t just speculation about insider trading — it’s already being prosecuted. Israeli authorities arrested several people and indicted two — a civilian and a military reservist — for using classified military information to place Polymarket bets about the timing of Israel’s strikes. They were charged with bribery and obstruction of justice. Israeli authorities said the bets pose “a real security risk to IDF operations and to the security of the state.”
This is the first publicly known instance of people being accused of leveraging military secrets to place prediction market bets. It demonstrates a concrete national security risk: military personnel with classified information now have financial incentives to leak operational details.
Polymarket’s Defiant Response
Polymarket CEO Shayne Coplan has previously defended informed traders, telling CBS News that insiders “having an edge on the market is a good thing” because it accelerates price discovery. The platform added an editorial note to its Middle East markets, calling prediction markets “particularly invaluable in gut-wrenching times like today.”
Congress is moving to regulate. Rep. Ritchie Torres introduced the Public Integrity in Financial Prediction Markets Act, and six Democratic senators urged the CFTC to “categorically prohibit any contract that resolves upon or closely correlates to an individual’s death.” Rival platform Kalshi, which is CFTC-regulated, does not allow betting on wars, terrorism, or assassinations.
The Ethics Question No One Can Ignore
The Verge captured it best: “Everything is gambling now, even human suffering.” Polymarket rapidly spun up additional markets after strikes began, including “Khamenei out as Supreme Leader by March 31?” (which resolved to 100% after his death was confirmed, with one trader making $757,000) and “Will the Iranian regime fall by June 30?” at 54%.
The platform’s aggressive defense reveals a fundamental clash between crypto’s “financialize everything” ethos and traditional ethical boundaries around profiting from violence. The informational value of prediction markets is real. But when a trader loses $6 million betting against strikes, and others profit from classified intelligence, the question is no longer theoretical: should there be limits on what can be turned into a financial instrument?
