Polymarket trading halted after vendor compromise; impacted users will be 'made whole'

Polymarket halted trading on its international platform for nearly an hour due to a third-party vendor compromise, with unconfirmed reports of user wallet drains totaling approximately $2.65 million in cryptocurrency. The company stated it will fully reimburse all affected traders and referred the incident to law enforcement; the U.S.-based platform was not affected. Polymarket, valued at $21 billion after a $1 billion investment led by Donald Trump Jr. in September, continues to face scrutiny over insider trading threats on its platform.
