Polymarket Plans $3.9M Refunds After Compromised Monitoring Script
The prediction market traced an October 29 incident to a third-party monitoring script and now says refunds, including losses from a trading pause, total $3.9 million.
Polymarket has outlined a $3.9 million refund program following an incident on October 29 that it attributes to a compromised third-party monitoring script, according to the platform's October 30 update.
The figure covers user losses connected to the disruption, including those arising from a pause in trading that accompanied the incident.
What the disclosure covers
- The incident date is October 29; the refund total was published in an October 30 update.
- Polymarket identifies a compromised monitoring script supplied by a third party as the cause.
- Refunds are set at $3.9 million and extend to losses tied to the trading halt.
The disclosure frames the problem as originating outside Polymarket's own code, pointing to the risks platforms carry when they rely on external tooling for operational monitoring. The update did not, in the details provided, specify a timeline for distributing the funds.
Prediction markets have grown quickly in volume and visibility, and incidents that force a trading halt put pressure on operators to document both the cause and the remedy. Polymarket's publication of a concrete refund total gives users a stated benchmark, though the practical test will be how quickly and completely those amounts reach affected accounts.
