OKX recorded approximately $445 million in net inflows over a 24-hour period, positioning it as the top performer among tracked cryptocurrency exchanges. This surge occurred concurrently with significant capital flight from Binance, which registered net outflows exceeding $7 billion. The shift in liquidity follows Binance’s reopening of withdrawals on Sunday at 6:00 a.m. UTC, after suspending them late Thursday due to a $6.3 billion hack, described as the largest in cryptocurrency history.
Data from DefiLlama indicates that Bybit followed OKX with $112 million in net inflows, while Gate and Bitget recorded $91 million and $54 million, respectively. Despite the massive outflow, Binance retained about $127.9 billion in wallets, more than four times the $29 billion held by OKX, the second-largest exchange by this metric. Binance reported that it had replenished approximately 95% of the affected assets by Sunday, up from 90% on Saturday, using its corporate treasury, the Secure Asset Fund for Users (SAFU), and portions of its futures insurance fund. The remaining 5% consists of less liquid tokens currently being acquired through market and over-the-counter transactions.
Binance stated that about $3 billion in stolen assets frozen by industry partners remains separate from its replacement funds. The exchange committed to absorbing losses without passing them to customers and published a new reserves snapshot on Sunday, with an updated proof-of-reserves report expected Monday. In token markets, OKX’s OKB rose 1.4% to near $113, while Binance’s BNB gained 0.3% to about $708.
The divergence in flow patterns between OKX and Binance highlights how immediate operational responses to security breaches influence short-term trader sentiment. While Binance maintains a dominant share of total assets under management, the rapid migration of $445 million into OKX suggests that traders are actively hedging against perceived counterparty risk or seeking alternative venues during periods of uncertainty. This behavior underscores the fragility of trust in centralized exchanges, where even substantial financial buffers like SAFU do not entirely prevent capital flight following high-profile incidents.
From a regulatory and compliance perspective, the speed at which Binance restored withdrawals and replenished assets sets a precedent for crisis management in the crypto sector. However, the reliance on internal funds and frozen external assets raises questions about long-term sustainability if similar attacks recur. Market participants will likely scrutinize the upcoming proof-of-reserves reports closely, as transparency becomes the primary mechanism for rebuilding confidence after such a significant breach.
