Polymarket halts trading after hack causes unauthorized withdrawals on its international platform

Polymarket's international prediction market platform experienced an outage after a third-party data provider was hacked, leading to unauthorized withdrawals from user wallets. The company paused trading on the platform, fixed the issue, and plans to refund affected users. It has also reported the incident to U.K. law enforcement, as the third-party provider operates there. The domestic platform remained operational, and trading is set to resume soon, just before the U.S. midterm elections when trading volumes are expected to rise.
