Polymarket Denies Data Breach Claim After Hacker Alleges 300K+ Records Compromised

GateNews
Prediction MarketSecurity Incidents
According to Polymarket's official statement, the prediction market platform has denied recent allegations that it suffered a data breach, saying the information being circulated involves public API endpoints and on-chain blockchain data. A hacker using the pseudonym "xorcat" claimed to have obtained more than 300,000 records, including approximately 10,000 user profiles with names and wallet addresses. Polymarket stated that its infrastructure is built around transparency, and the dataset was compiled from publicly accessible sources rather than from any internal system compromise, describing the breach claims as "complete and utter nonsense." Security researchers have echoed this view, suggesting the data was scraped from public sources rather than extracted through unauthorized access.
