“We are putting together a solution together with FTX to initiate a pathway forward,” Mr. Sun said on Twitter on Wednesday night. He did not respond to a request for comment.
Scrutiny of Mr. Bankman-Fried is growing in Washington. For several months, the S.E.C. had been asking the company to voluntarily turn over information. Now it’s pursuing an investigation into FTX’s collapse, two people familiar with the matter said. The Commodity Futures Trading Commission is also looking into the crisis. And federal prosecutors in Manhattan have started an inquiry, a person briefed on it said.
One issue that the federal authorities are examining is whether FTX misused customer funds to prop up Alameda. The two companies are technically separate, but they have close financial ties: Both were founded by Mr. Bankman-Fried, and Alameda conducts trades on FTX’s platform.
“The recent collapse of FTX is a loud warning bell that cryptocurrencies can fail,” Senator Sherrod Brown, the Ohio Democrat who leads the Senate’s banking committee, said in a statement. “It is crucial that our financial watchdogs look into what led to FTX’s collapse so we can fully understand the misconduct and abuses that took place.”
The collapse of FTX has also shaken its employees, some of whom say they feel betrayed. Many received their salaries through deposits into their FTX accounts, meaning the implosion of the company could drain their savings, a person familiar with the matter said.
In the memo to employees, Mr. Bankman-Fried apologized for the chaos. “Ultimately it’s my responsibility to make sure the right things happen,” he said.
He said that two executives, Ryne Miller and Zach Dexter, were handling day-to-day operations at the firm’s U.S. arm, and that Constance Wang, the firm’s chief operating officer, was involved in the fund-raising efforts.
Mr. Bankman-Fried, in a somewhat unusual move, also took to Twitter on Thursday morning to post a mea culpa of sorts, in which he said, “I’m sorry” and “should have done better.” In a series of posts, he said he could not communicate more with customers and investors because his “hands were tied during the duration of the possible Binance deal.”
A lawyer for Mr. Bankman-Fried at the law firm Paul Weiss did not return a request for comment.
