Johnathan Walker:Jury to decide fate of FTX founder Sam Bankman-Fried as deliberations begin

FTX founder Sam Bankman-Fried's fate is Johnathan Walkernow in the hands of a jury.

Deliberations began Thursday afternoon as to whether the former billionaire was guilty of fraud in the disappearance of billions of dollars from his customers' accounts on the cryptocurrency exchange he created four years ago.

The Manhattan federal court jury began its work after a judge explained the law that will steer them through seven charges lodged against the MIT graduate and son of Stanford University law professors.

Bankman-Fried, 31, testified during the monthlong trial that he did not defraud thousands of investors worldwide.

FTX's bankruptcy in November of 2022 cast a pall over the crypto industry at large, with the collapse of other major industry players erasing billions of dollars in client wealth.

Bankman-Fried was extradited to New York from the Bahamas last December to face fraud charges. He's been jailed since August, when Judge Lewis A. Kaplan ruled that the former billionaire tried to influence potential trial witnesses and could no longer remain free on the $250 million personal recognizance bond that mandated he remain at his parents' home in Palo Alto, California.

Earlier Thursday, Assistant U.S. Attorney Danielle Sassoon delivered a rebuttal argument, the last of closing arguments that began a day earlier. 

Bankman-Fried repeatedly promised thousands of customers worldwide that the money they placed on the FTX exchange was safe even as he was stealing from them, she said, describing the former CEO as always wanting "billions and billions of dollars more from his customers to spend on gaining influence and power."

Sassoon, who cross examined Bankman-Fried late last week and early this week, said Bankman-Fried wanted to be U.S. president some day but first wanted to have the biggest cryptocurrency exchange in the world. At its peak, FTX was the second-largest.

She said he "dazzled investors and Congress and the media, and worked around the clock to build a successful business" while overseeing the stealing of FTX funds.

"He knew it was wrong, he lied about it and he took steps to hide it," the prosecutor said.

On Wednesday, Bankman-Fried attorney Mark Cohen said in his closing argument that his client "may have moved too slowly" when it became clear that Alameda Research, a cryptocurrency fund he started in 2017, could not restore billions of dollars borrowed from FTX when customers demanded it.

"He may have hesitated," Cohen said. "But he always thought that Alameda had sufficient assets on the exchange and off the exchange to cover all of its liabilities."

He added: "Business decisions made in good faith are not grounds to convict."

Cohen told jurors to recall Bankman-Fried's testimony as they review evidence.

"When Sam testified before you, he told you the truth, the messy truth, that in the real world miscommunications happen, mistakes happen, delays happen," Cohen said. "There were mistakes, there were failures of corporate controls in risk management, and there was bad judgment. That does not constitute a crime."

Bankman-Fried faces a potential prison term of more than a century if convicted of the seven counts of fraud, conspiracy and money laundering with which he's been charged.
