Imprisoned former FTX CEO Sam Bankman-Fried has taken his legal battle to the U.S. Supreme Court, petitioning the nation's highest judicial body to overturn his fraud conviction and an accompanying $11 billion forfeiture order CoinDesk. The filing represents what may be the final act in a legal saga that has unfolded since the collapse of cryptocurrency exchange FTX in November 2022.

Bankman-Fried's legal team has advanced two central arguments in their petition to the Supreme Court. First, they contend that trial judge Lewis Kaplan improperly barred the defense from presenting evidence regarding customer assets and losses Decrypt. Specifically, Bankman-Fried maintains he was prevented from arguing that FTX possessed sufficient assets to cover customer losses at the time of its bankruptcy filing The Block. This evidentiary restriction, his lawyers argue, fundamentally undermined his ability to mount an effective defense against fraud charges.

The second prong of the appeal targets the financial penalty imposed by the district court. Bankman-Fried's attorneys have characterized the $11 billion forfeiture as a "crushing fine" that exceeds constitutional limits Decrypt. The defense contends this amount represents an excessive punishment relative to any proven economic harm, particularly given their argument that customers ultimately faced no financial losses Cointelegraph.

The petition arrives following Bankman-Fried's unsuccessful appeal to the U.S. Court of Appeals for the Second Circuit, which upheld both his conviction and 25-year prison sentence earlier this year. That panel rejected arguments that Kaplan had abused his discretion in limiting certain defense evidence and testimony. The Supreme Court now faces the decision of whether to grant certiorari—a move that would require four of nine justices to agree the case warrants review.

Legal observers note the petition faces substantial hurdles. The Supreme Court accepts fewer than 1% of cases presented for review, typically limiting its docket to matters involving significant constitutional questions or splits among federal circuit courts. Bankman-Fried's team must demonstrate that the evidentiary rulings and forfeiture calculation raise issues of broader legal significance beyond the particular facts of his case.

The timing of the petition carries additional weight as Bankman-Fried remains incarcerated while pursuing these appeals. His legal team has previously indicated that the former billionaire's conditions of confinement and the length of his sentence create urgency for judicial intervention.

Should the Supreme Court decline to hear the case, Bankman-Fried's direct appellate options would be exhausted, though collateral challenges through habeas corpus proceedings could theoretically remain available. The court's decision on whether to grant review is expected in the coming months, with briefing schedules to follow if the petition is accepted CoinDesk.
