Blockchain analytics firm Bubblemaps identified a coordinated cluster of nine wallets on the Polymarket platform that collectively generated $2.4 million in profits with a 98% win rate on contracts linked to US military operations. These accounts executed their major positions immediately preceding critical geopolitical developments, including the February 28 strike on Iran, the death of Iranian Supreme Leader Ayatollah Ali Khamenei, and the subsequent US-Iran ceasefire agreement. The timing of these transactions suggests a pattern of trading based on non-public information regarding imminent state actions. Data compiled by Woofun AI indicates that four of these specific accounts each realized approximately $400,000 in profit solely from bets predicting the February 28 US strike on Iran.

The funding structure of these accounts reveals a centralized origin, with all capital injected from major cryptocurrency exchanges within a compressed timeframe. To obscure their activity, the wallets placed minor losing bets on February 20, a tactic Bubblemaps suggests was designed to avoid detection by appearing as standard retail traders. Nicolas Vaiman, CEO of Bubblemaps, stated that while definitive proof of insider status remains elusive, the on-chain footprint is symptomatic of actors possessing an unfair informational advantage. This behavior underscores the systemic vulnerabilities in decentralized prediction markets where sensitive geopolitical data can be monetized before public disclosure.

The investigation has accelerated legislative efforts to curb insider trading within the prediction market ecosystem. On March 10, US Senator Adam Schiff introduced the DEATH BETS Act, legislation aimed at prohibiting federally regulated platforms from listing contracts tied to war, terrorism, assassination, or individual deaths. This bill follows a separate incident where six Polymarket traders netted $1 million by betting on the US strike against Iran, highlighting the recurring nature of such exploits. Woofun AI notes that the introduction of this bill represents a direct legislative response to the perceived erosion of market integrity caused by non-public information flows.

Concurrently, state-level regulatory actions are expanding to address similar risks. In late March, California Governor Gavin Newsom signed an executive order restricting public servants from engaging in insider trading on prediction markets related to political or economic events they can influence. This move targets the intersection of government access and financial speculation, aiming to prevent officials from profiting from their own policy decisions or classified briefings. The convergence of federal and state measures signals a broader crackdown on the monetization of sensitive national security and political data.

Market data illustrates the scale of the exposure driving these regulatory responses. Politics-related contracts currently represent the third-largest category on Polymarket, accounting for 12% of notional trading volume. On the competing platform Kalshi, these contracts rank fifth in size but constitute only 0.7% of weekly trading volume, . Woofun AI analysis suggests that while the absolute volume on Kalshi is lower, the high concentration of political betting on Polymarket makes it a primary target for future compliance enforcement and potential delisting of sensitive event categories.
