Blockchain investigator ZachXBT has flagged a suspected security breach on Polymarket, the leading decentralized prediction market platform. Over $520,000 was drained from two smart contracts on the Polygon blockchain, according to on-chain data shared by ZachXBT.
Polymarket developers confirmed the issue on X, stating it was a private key compromise of an internal operations wallet, not a broader smart contract exploit. They assured users that funds and market resolutions remain safe. Polygon Labs CTO Mudit Gupta echoed this, saying, "Polymarket contracts are safe. User funds are safe."
