Reuters probe flags 152 Polymarket wallets for possible military insider trading
A research report identified 152 Polymarket wallets that reaped $8 million trading military and defense markets, with subsequent trades by large accounts and bots appearing to copy the suspicious bets before military action. The finding, published August 20, raises concerns that insider signals on the CFTC-regulated platform may be leaking to sophisticated followers. Research firm ACDC conducted the analysis. Polymarket settles wagers on a public blockchain, making betting patterns visible while trader identities remain anonymous.
The 152-wallet pattern turns suspicion into measurable signal. Bots and whales copied the suspicious bets before military action, which means possible insider knowledge did not stay secret; it propagated through Polymarket's transparent order book to traders with no clearance. For Polymarket, the problem is now twofold: proving it can police leaks it cannot see, and explaining why a CFTC-regulated venue became a broadcast system for national-security information.
Kalshi has already moved controls upstream in response to similar risks. Democratic lawmakers in California and Nevada pressed the CFTC to tighten oversight this week. A mandate for pre-trade screening or retroactive wallet tracing would force Polymarket to rebuild its surveillance infrastructure. Traders in defense markets face contract voiding if investigations accelerate. The Reuters wallet study strengthens the political case for intervention.
The Reuters wallet study joins the Israeli Air Force major arrest and the earlier U.S. soldier prosecution as the third major military-trading revelation this quarter, cementing national-security contracts as the prediction-markets industry's highest regulatory liability.
