His arrest is the first concrete move by regulators to hold individuals accountable for the multibillion-dollar implosion of FTX last month.

Sam Bankman-Fried is expected to be extradited to the United States.

FTX founder Sam Bankman-Fried was arrested by Bahamian authorities Monday evening after the United States Attorney for the Southern District of New York shared a sealed indictment with the Bahamian government, setting the stage for extradition and U.S. trial for the onetime crypto billionaire at the heart of the cryptocurrency exchange's collapse.

His arrest is the first concrete move by regulators to hold individuals accountable for the multibillion-dollar implosion of FTX last month.

Before his arrest was announced, Bankman-Fried had been expected to testify virtually before the House Financial Services Committee on Tuesday, but his attorneys told CNBC that he will not appear. Rep. Maxine Waters, D-Calif., who oversees that committee, said she was "surprised" at his arrest and disappointed that Congress would not be able to hear from him on Tuesday.
