On February 28, 2026, joint military strikes by the U.S. and Israel against targets in Iran triggered massive financial shifts on the decentralized prediction platform Polymarket. The event underscores the high-stakes nature of geopolitical betting, resulting in a multi-million dollar wipeout for one prominent trader while netting significant gains for others.
The most notable loss came from a user operating under the pseudonym "anoin123," who suffered a total wipeout of approximately $6.5 million. This trader had systematically placed large wagers betting against the likelihood that President Donald Trump would greenlight a direct military intervention. When munitions hit Tehran and other Iranian cities, those contracts became worthless.
Conversely, some users capitalized on the escalation. A trader known as "Vivaldi007" realized a profit of $385,000 after betting on a joint attack since early February. More controversially, a new wallet titled "Roeyha2026" was funded just 11 hours before the strikes began. The anonymous user wagered $50,000 that a strike would occur before March 1, nearly doubling their money. This specific timing has sparked intense debate and speculation regarding potential insider trading involving classified military intelligence.
The event has fueled political pressure to regulate prediction markets. While the Trump administration has generally fostered a pro-crypto environment, lawmakers like Senator Chris Murphy are now pushing for legislative frameworks to curb these platforms, citing concerns over the commodification of war and the risk of defense insiders profiting from military actions.
