Polymarket users report unauthorized asset withdrawals in suspected frontend attack

  • —Trader Car lost about $800,000, with all positions sold off
  • —Another user reported losses of roughly $200,000
  • —Users received unauthorized withdrawal signature requests on the site
  • —A June 2026 frontend phishing attack drained $2.94 million from users
Why it matters: A second frontend compromise at Polymarket undermines confidence in the largest prediction market and risks an outflow of liquidity.
