Polymarket states that the security incident reported by ZachXBT was due to an internal operations wallet private key leak, and that user funds and market settlements are secure.

According to ChainCatcher, Polymarket staff member Shantikiran Chanal posted on X platform stating that they have taken note of a security report related to reward distribution, and that user funds and market settlements are in a safe state. The investigation points to a private key leak in a wallet used for internal operations, rather than an issue with contracts or core infrastructure. More updates will be released subsequently.
