Sam Trabucco

John Samuel Trabucco is an American business executive. He was co-CEO of Alameda Research, a defunct quantitative trading firm founded by Sam Bankman-Fried before FTX. Caroline Ellison was Alameda's other co-CEO. Trabucco stepped down from Alameda in August 2022, leaving Ellison as sole CEO until its bankruptcy along with FTX three months later.

Early life and education Trabucco attended a Mount Holyoke College math camp in 2010 where he met Sam Bankman-Fried. Trabucco received his bachelor's in mathematics and computer science from Massachusetts Institute of Technology (MIT). There he also served as president of the undergrad math association and reconnected with Bankman-Fried.

Career After graduation, he worked for Susquehanna International Group, a quantitative trading firm. He joined Alameda Research in March 2019, and officially became the co-CEO in October 2021 along with Caroline Ellison. Alameda Research purchased a 52-foot yacht for Trabucco, who named it Soak My Deck.

In 2024, court filings in the FTX bankruptcy proceedings revealed that Trabucco had reached a settlement with U.S. authorities, agreeing to forfeit assets worth approximately $80 million, including two San Francisco apartments, a yacht, and claims against FTX. He also agreed to transfer rights to about $70 million in claims against the exchange. FTX debtors stated that they believed they had strong claims against Trabucco but opted to settle to avoid costly and time-consuming litigation.
