Bybit claims new fraud system stopped $300M of risky withdrawals in Q4 2025

Bybit says most of the $300 million “saved” came from users backing out after real-time warnings, highlighting how exchanges are shifting from recovery to preemptive fraud stops.

Bybit said it blocked or disrupted more than $300 million worth of suspected scam-related withdrawals in the fourth quarter of 2025 after rolling out an AI-assisted risk monitoring system designed to flag malicious transactions before funds leave the exchange.

In a company blog post, Bybit said its system flagged about $500 million in withdrawal requests during the quarter and that more than 4,000 users were “protected” after the platform issued real-time risk alerts or blocked transactions outright.

Bybit’s head of group risk control, David Zong, told Cointelegraph that much of the $300 million total reflects withdrawals users voluntarily cancelled after seeing warnings, meaning the funds remained in their accounts rather than requiring clawbacks or reimbursement.
