Bubblemaps flags nine Polymarket wallets with 98% win rate on Iran military contracts
Blockchain analytics firm Bubblemaps identified a cluster of nine linked wallets on crypto prediction market Polymarket that earned $2.4 million with a 98% win rate on contracts tied to U.S. military operations against Iran, according to reports published Monday, May 19, 2026. Sen. Elissa Slotkin separately noted that more than 150 Polymarket accounts placed bets predicting a U.S. strike hours before military action began. Bubblemaps, which visualizes on-chain wallet connections, flagged the coordinated activity but did not identify the operators. The findings follow earlier scrutiny from a 60 Minutes investigation and add to questions about surveillance gaps on the platform.
Polymarket must now defend against five concurrent federal and journalistic probes into the same wallet cluster. Any confirmation that its surveillance systems missed nine linked accounts trading ahead of a military strike could force immediate KYC upgrades before the House votes on Senate-passed account-exclusion legislation.
Becomes the third major investigation this week of suspected insider trading on Polymarket military contracts, after parallel CBS and NYT probes already put the platform under federal scrutiny.
