FTX CEO Sam Bankman-Fried has appealed for a $2 billion to $4 billion cash injection from OKX on Monday morning just prior to the announcement of the now collapsed acquisition mooted by arch rival Binance, said a senior executive at OKX. The CEO of the troubled exchange had presented "a lot of urgency" in seeking that amount of cash injection during a call on November 8, as this would have helped FTX survive a short-term liquidity crisis, said Lennix Lai, director of financial markets at OKX.
