Sam Bankman-Fried, founder of now-bankrupt crypto exchange FTX, is expected to appear in court in the Bahamas on Monday and agree to be extradited to the United States, where he faces fraud charges.

Bankman-Fried initially said he would fight extradition after his arrest a week ago in the Bahamas, where he lives and FTX is based. He was denied bail and remanded to the Caribbean nation's Fox Hill prison.

Reuters reported first on Saturday that Bankman-Fried would return to court to reverse his decision.

The 30-year-old crypto mogul rode a boom in the value of Bitcoin and other digital assets to become a billionaire several times over and an influential political donor in the United States, until FTX collapsed in early November after a wave of withdrawals. The exchange declared bankruptcy on Nov. 11.

Federal prosecutors in Manhattan said Bankman-Fried stole billions of dollars in FTX customer deposits to plug losses at his crypto hedge fund, Alameda Research. They accuse Bankman-Fried of misleading lenders and investors, conspiring to launder money, and violating U.S. campaign finance laws.

Bankman-Fried has acknowledged risk management failures at FTX but said he does not believe he has criminal liability.

Upon being extradited to the United States, Bankman-Fried would be required to appear before a judge in Manhattan within two days, though the hearing would likely take place quickly. He would be asked to enter a plea, and the judge would make a determination on bail.

Prosecutors are expected to argue that Bankman-Fried is a flight risk and should remain in custody because of the large sums of money involved in the case and the unclear location of those funds.

Bankman-Fried would likely be held at the Metropolitan Detention Center in Brooklyn, though due to overcrowding there some federal defendants are being held at jails just outside New York City, said Zachary Margulis-Ohnuma, a New York defense lawyer at ZMO Law PLLC who is not involved in the case.

It was not immediately clear what prompted Bankman-Fried to change his mind on extradition. In a 2021 report, the U.S. State Department described "harsh" conditions at the Fox Hill correctional facility where Bankman-Fried was being held, with overcrowding, rodent infestation and prisoners using buckets as toilets. Bahamas authorities say conditions have since improved.

Bankman-Fried had been remanded to the prison on Tuesday after Chief Magistrate JoyAnn Ferguson-Pratt rejected his request to remain at home while awaiting a hearing on his extradition.

In the United States it is highly unusual for judges to deny bail to defendants accused of non-violent financial crimes, though they typically demand steep dollar amounts and impose onerous monitoring conditions.

High-profile defendants including Ponzi schemer Bernard Madoff, Theranos founder Elizabeth Holmes, and Enron executives Jeffrey Skilling and Kenneth Lay were all granted bail before trial.

Damian Williams, the top federal prosecutor in Manhattan, last week described the collapse of FTX as one of the "biggest financial frauds in American history." He has said the office's investigation is ongoing, and called on people with knowledge of wrongdoing at FTX or Alameda to cooperate.

Any trial of Bankman-Fried is likely more than a year away, legal experts told Reuters.
