Federal prosecutors have raised serious questions about the authenticity of a letter submitted by convicted FTX founder Sam Bankman-Fried from prison, introducing a new complication in his bid for a new trial. The letter, filed on March 16, 2025, with Judge Lewis A. Kaplan of the Southern District of New York, was intended to support arguments for a retrial but contained multiple irregularities that have sparked a legal firestorm.
Prosecutors identified three primary discrepancies. First, tracking information showed the letter was shipped via FedEx from Palo Alto or Menlo Park, California—hundreds of miles from the Metropolitan Detention Center in Brooklyn where Bankman-Fried is incarcerated. Second, the letter mislabeled the federal detention facility as a state institution. Third, it featured a typed "/s/" designation instead of an actual handwritten signature.
These findings violate Federal Bureau of Prisons regulations, which explicitly prohibit inmates from using private carriers like FedEx for outgoing mail, mandating use of the United States Postal Service through approved prison systems for security, screening, and chain-of-custody purposes. Prosecutors stated these discrepancies provide "reason to doubt" the letter was sent by Bankman-Fried himself, though they stopped short of directly accusing the defendant or his associates of fabricating the document.
The development adds an unusual wrinkle to Bankman-Fried's post-conviction fight. The former crypto mogul, sentenced to 25 years in March 2024 for fraud and conspiracy related to the collapse of the FTX exchange, has repeatedly argued he did not receive a fair trial. He has pointed to what he claims is new evidence, including the later recovery of customer funds through the FTX bankruptcy process. However, appellate judges have previously signaled skepticism toward this argument, emphasizing the case turned on how customer funds were used and represented at the time, not whether creditors were later made whole.
The authenticity challenge directly impacts the new trial request, as judges must evaluate the credibility of all submitted materials. Legal experts note the burden now falls on Bankman-Fried's legal team to demonstrate the letter's legitimate origin. Judge Kaplan has several options, including holding an evidentiary hearing or requesting additional documentation before considering the letter's content.
