I think that would be an uphill battle. The money that flowed to Caroline looked like: a base salary of $200,000 a year, semiannual bonuses of up to $20 million, a de minimis equity stake in FTX, and no equity in Alameda. I don’t know what SBF’s salary or bonuses (if any) looked like, but he had a controlling stake in FTX, 90% of Alameda, and borrowed from his companies several times for hundreds of millions at a time. Caroline was nominally the CEO of Alameda but she clearly was not the one in charge of the corporate empire, and if she was masterminding the fraud she did a very poor job of monetizing it.
It’s also not strictly he-said/she-said; there were at least two other executives who knew what was going on, both of whom implicated Sam as the mastermind.
