Caroline Ellison, whose testimony helped convict Sam Bankman-Fried, faces her own sentencing

New York, CNN — A year ago, Caroline Ellison was preparing to testify against her former boss and ex-boyfriend in one of the biggest fraud trials in US history. On Tuesday, she’ll learn whether her own gamble — cooperating with prosecutors in the hopes of staying out of prison — will pay off.

A quick recap:

  • FTX was a buzzy, celebrity-backed startup that allowed people to buy and sell digital assets.
  • It collapsed in November 2022, when customers pulled their funds en masse amid rumors about FTX’s unusually close ties to its founder’s crypto hedge fund, Alameda Research.
  • Ellison, who ran Alameda, pleaded guilty to seven federal counts of fraud and conspiracy shortly after FTX’s collapse. She was one of several company insiders to turn against Sam Bankman-Fried, who founded both firms, and pinpoint him as the leader of a scheme to defraud investors and steal $8 billion from FTX customer funds.
  • Bankman-Fried, who pleaded not guilty, was convicted and sentenced to 25 years in prison. He filed his appeal last week.

Ellison’s testimony at Bankman-Fried’s trial last fall was crucial.
