Nicolas Roos

Served as an Assistant United States Attorney for the prosecution, examining government witnesses and delivering the government's closing argument. His examination work included portions of Gary Wang's direct testimony on Days 3 and 4 and redirect on Day 5, portions of Zac Prince's direct testimony on Days 7 and 8 and redirect on Day 8, portions of Nishad Singh's direct testimony on Day 9 and redirect on Day 10, and Peter Douglas Easton's redirect on Day 11.

In the Day 18 closing, Roos organized the government's case around two asserted means by which Alameda used FTX customer assets: undisclosed account privileges on the exchange and customer fiat deposits routed to Alameda bank accounts. He cited code records, spreadsheets, metadata, financial tracing, public statements, and witness testimony to argue that Bankman-Fried knew about the multibillion-dollar shortfall, continued spending customer assets, concealed the situation, and sent misleading assurances during the November withdrawal crisis.

Roos connected that evidence to the seven charged offenses involving FTX customers, Alameda lenders, FTX investors, commodities fraud, and money laundering. He contrasted Bankman-Fried's public claims and trial testimony with the government's evidence, rebutted the defense theories of good faith, eventual repayment, and spot margin, acknowledged the government's burden of proof and the controlling role of the court's instructions, and requested guilty verdicts on every count. These were arguments presented to the jury rather than court findings.
