Study flags 152 anonymous Polymarket wallets for possible trades tied to advance military information
New research from the Anti-Corruption Data Collective, or ACDC, says at least 152 anonymous wallets on Polymarket may have traded on advance knowledge related to U.S. military and defense events, generating about $8 million in profit with an average win rate of 97.2%. The group said it screened settled Polymarket markets for what it described as low-probability, high-value wagers: trades worth at least $2,500 within one hour on outcomes priced at 35% or lower. That process identified 556 wallets with unusual patterns, including 152 linked to military and defense markets. ACDC referred to these wallets as “Orcas,” describing them as addresses that appear suddenly, place bets on unlikely outcomes, win at unusually high rates, and then exit with profits. The researchers said blockchain data alone cannot identify the people behind the wallets or verify where any information came from, so the findings do not by themselves prove insider trading. The report lands as regulators keep a close watch on prediction-market abuse. The CFTC has already brought separate cases this year involving alleged use of confidential information in Polymarket trading.
