Predict.fun Promises Full Refunds Following 400,000 USDT Wallet Breach

The BNB Chain prediction market confirmed the security breach on October 27, noting that only a small number of users were impacted by the unauthorized activity. While the company has taken the external documentation site offline to prevent further exposure, it has not provided a specific timeline for restoring access to the portal. The firm stated that its preliminary findings point to an exploit within the third-party infrastructure, though it has yet to detail the specific technical vector used to bypass wallet security.

Following the incident, the platform committed to a full post-mortem report to be released once investigators have finalized their review. This breach mirrors similar challenges in the prediction market sector, such as the June incident at Polymarket where a vendor compromise allowed attackers to inject malicious scripts into the frontend. Predict.fun, which launched in December 2025 and has since facilitated over $1.8 billion in trading volume, maintains that it will cover all losses directly resulting from the current exploit.
