Sam Trabucco

Trial testimony described Trabucco as an Alameda trader who became co-CEO with Caroline Ellison in 2021. Ellison placed him at a discussion about financing the purchase of Binance's FTX stake and in a Signal discussion concerning payments made in connection with unfreezing Alameda accounts in China. A related chat containing his comment about whether an employee's father had reported them was admitted as Government Exhibit 1631; the court instructed the jury that the possible-bribe evidence did not concern a charged crime and could be considered only for limited purposes.

Other testimony and exhibits connected Trabucco to Alameda trading and risk discussions. Bankman-Fried said Trabucco participated in the Vertex trading chat and remained on a later hedging thread, though he was then commenting little and was effectively out of the picture. Cross-examination also introduced a January 2022 chat with Trabucco and Ellison about OXY and MAPS purchases; Bankman-Fried disputed that his messages constituted trading directions.
