Polymarket Hack Totals $3.1M as Platform Vows Full Refunds
A security breach at prediction market platform Polymarket has grown to $3.1 million, with the company pledging to make affected users whole.
Polymarket, one of the most prominent decentralized prediction market platforms in the crypto space, has confirmed that a security exploit has resulted in losses totaling $3.1 million — a figure that was revised upward in the days following the initial disclosure.

The incident serves as a reminder that prediction markets, despite their innovative structure, carry the same custodial and smart-contract risks that have defined crypto's ongoing security challenge.
