Follow live updates on the Sam Bankman-Fried fraud trial.

A year ago, Sam Bankman-Fried was a fixture on magazine covers and in the halls of Congress, a tousle-haired crypto billionaire who hobnobbed with movie stars and bankrolled political campaigns.

On Tuesday, the founder of the failed FTX digital currency exchange is set to leave the jail where he has been confined for more than seven weeks and stand trial in a Manhattan courtroom on federal charges of fraud and money laundering, capping one of the largest and swiftest corporate collapses in decades.

The charges against Mr. Bankman-Fried, 31, have put the rest of the crypto industry on trial with him. He has emerged as a symbol of the unrestrained hubris and shady deal-making that turned cryptocurrencies into a multitrillion-dollar industry during the pandemic. The demise of FTX in November helped burst that bubble, sending other high-profile companies into bankruptcy and provoking a government crackdown.

The trial will offer a window into the Wild West-style financial engineering that fueled crypto’s growth and lured millions of inexperienced investors, many of whom lost their savings when the market crashed. Lawyers on both sides of the case are expected to lay bare the culture of scams and risk-taking that surrounded FTX and to dissect the often-misleading publicity campaigns that helped drive years of crypto hype.

“It’s a fraud that was enabled and supercharged by crypto, and by crypto’s unique aspects,” said Lee Reiners, a crypto expert who teaches at Duke Law School. “It wouldn’t have been possible in any other context.”

Jury selection begins on Tuesday in U.S. District Court, with the trial expected to last six weeks. Camera crews and reporters are expected to swarm the courthouse, and the author Michael Lewis has a widely anticipated book about the case coming out that same day, featuring behind-the-scenes details of Mr. Bankman-Fried’s rise and fall.

Mr. Bankman-Fried, who faces seven criminal counts, is accused of orchestrating a yearslong fraud that siphoned billions of dollars from customers to finance political contributions, venture capital investments and luxury real estate purchases. He has pleaded not guilty. If convicted, he could receive what would amount to a life sentence.

He faces an uphill battle. Three of his closest advisers have pleaded guilty and agreed to testify against him. Prosecutors have accumulated millions of pages of digital evidence, including text transcripts, financial records and emails, and they plan to introduce about 1,300 exhibits at the trial. The judge, Lewis A. Kaplan, has repeatedly sided with the prosecution in procedural disputes, rejecting expert witnesses the defense had hoped to call and allowing the government to use evidence that Mr. Bankman-Fried had contested.

For the past month and a half, Mr. Bankman-Fried has also had to prepare his case from a jail cell in Brooklyn, after Judge Kaplan revoked his bail, ruling that he had tried to interfere with witnesses.

“It doesn’t appear that there’s any sort of path to victory” for Mr. Bankman-Fried, said Renato Mariotti, a former federal prosecutor.

Also looming over the trial is the question of whether Mr. Bankman-Fried, who is unusually garrulous for a criminal defendant, will testify — a high-risk move that defense lawyers tend to discourage.

“It will surely be painful for him to remain quiet if he believes or convinces himself that the government is mischaracterizing his transactions and his closest associates are making up stories about him,” said Daniel Richman, a law professor at Columbia University and a former federal prosecutor. The downside is “he might not respond well to forceful cross-examination.”

A representative for Mr. Bankman-Fried declined to comment. A spokesman for the U.S. attorney’s office for the Southern District of New York, the division that is prosecuting Mr. Bankman-Fried, also declined.

Known for his signature outfit of T-shirts and shorts, Mr. Bankman-Fried rose to prominence as a rare good guy in the loosely regulated world of crypto. He founded FTX in 2019 and raised $2 billion in venture funding, promising to work with regulators to write new rules for the industry. He was also a prolific political donor, contributing more than $5 million to support Joseph R. Biden’s 2020 presidential run.

Then, over four frantic days in November, FTX and its sister hedge fund, Alameda Research, imploded, with customers unable to withdraw more than $8 billion in deposits. The companies filed for bankruptcy, and Mr. Bankman-Fried was charged with counts including securities fraud, wire fraud and money laundering. A count accusing him of violating campaign finance law was eventually dropped, along with a handful of other charges, though all could be revived at a second trial next year.

Many of his closest allies have turned on him. Caroline Ellison, Alameda’s chief executive and Mr. Bankman-Fried’s on-and-off girlfriend, pleaded guilty and agreed to cooperate with the prosecution. She was joined by two co-founders of FTX, Gary Wang and Nishad Singh, who admitted to conspiring with Mr. Bankman-Fried to defraud customers. A fourth high-level executive, Ryan Salame, also pleaded guilty, without agreeing to cooperate.

After his arrest, Mr. Bankman-Fried was confined to his parents’ house in Palo Alto, Calif., where he entertained guests and had a pickleball court installed in the yard. In August, Judge Kaplan revoked those privileges and sent him to the Metropolitan Detention Center after he shared some of Ms. Ellison’s private writings with The New York Times.

Ms. Ellison is poised to be a crucial figure at the trial. She, Mr. Wang and Mr. Singh were all close friends with Mr. Bankman-Fried and lived together in a five-bedroom penthouse in the Bahamas, where FTX had its headquarters. But even within that tight circle, Ms. Ellison had unique access — and a long romantic history with her boss that could create one of the most dramatic and personal moments of the trial.

In court filings, prosecutors have previewed some of the evidence they plan to present, including notes that Ms. Ellison took at meetings with Mr. Bankman-Fried, as well as spreadsheets that “kept track of illicit money flows.” Prosecutors have also lined up testimony from FTX investors and customers who lost money in the firm’s collapse.

The contours of Mr. Bankman-Fried’s defense are less clear. After FTX’s bankruptcy, he blamed an accounting error that he said had caused billions of users’ dollars to vanish without his knowledge. He has also criticized his colleagues, especially Ms. Ellison, saying she failed to manage risk at Alameda. And in legal filings, Mr. Bankman-Fried’s lawyers have indicated that they’ll argue that outside law firms authorized his actions at FTX.

More recently, the defense has also suggested that FTX’s use of customer deposits to make investments was akin to how a bank operates. The problem for Mr. Bankman-Fried is that FTX was an exchange, a type of company that isn’t supposed to put customer money at risk.

As the trial approaches, the defense has faced setbacks. Mr. Bankman-Fried has had trouble getting access to documents from jail, his lawyers say, because of a spotty internet connection and battery problems with a laptop he was given.

Judge Kaplan has mostly dismissed those complaints. Last month, he rejected the defense’s attempt to stop prosecutors from citing evidence related to FTX’s bankruptcy filing and Mr. Bankman-Fried’s resignation from the company. The judge said those events were “intertwined inextricably” with the charges. And in a ruling Sunday, he said he might limit the defense’s ability to argue that some of the decisions made at FTX involved lawyers.

“The issues in this case are pretty straightforward,” Judge Kaplan said at a court hearing last week.

The pretrial disputes have put the defense on the back foot. But ultimately the legal wrangling could help Mr. Bankman-Fried mount an appeal if he loses at trial.

“The defense here is doing a really nice job of creating a record on that,” said Jordan Estes, a former federal prosecutor in Manhattan. “They’re setting up this theme that they’re not getting due process, they’re not getting a fair trial.”
