Recently, six wallets on Polymarket made precise positions before the U.S. attacked Iran and profited $1.2 million, then continued betting on Iranian nuclear facilities, and later coordinated $100,000 in bets predicting a U.S.-Iran ceasefire. This series of trades has triggered market concerns about information advantages and highlighted a trust crisis in prediction markets. Changes in market participants' behavior reflect worries about informed trading, and the contradiction between transparency and anonymity makes accountability difficult to trace.
