How Bitget Lost $15B: What It Means for DeFi Users

Bitget, one of the largest centralized derivatives exchanges by open interest, confirmed on September 25, 2026 that approximately $387.5 million in customer assets was transferred to attacker-controlled addresses following a hot wallet breach identified the previous day, while circulating claims of a $15 billion loss remain unsupported by any primary source, on-chain record, or independent forensic report reviewed at publication time. The $15 billion figure circulating across social media does not correspond to any confirmed loss, balance-sheet shortfall, or customer deposit gap identified in Bitget’s official incident disclosures or in blockchain-analysis reports from TRM Labs, SlowMist, or Mandiant.
