The U.S. Marshals Service sold Anthropic shares forfeited by former FTX executives Caroline Ellison and Nishad Singh in 2025, converting their combined roughly $50 million 2022 Series B investment into a major federal forfeiture tied to the exchange’s collapse. Ellison invested about $10 million through a Simple Agreement for Future Equity in March 2022 that became Series B preferred stock, and Singh invested about $40 million; a federal judge finalized Ellison’s forfeiture in February 2025 and Singh’s in April after both pleaded guilty and cooperated against Sam Bankman-Fried. Business Insider, citing a person familiar with the matter, reported the Marshals sold the blocks to investors already on Anthropic’s capitalization table, without confirming the price, buyers, or exact date. Outside estimates put 2025 sale proceeds at roughly $250 million to $1.1 billion, while PitchBook and UCLA analysts have valued the same forfeited stake at about $2.62 billion to $5.03 billion on more recent private-market pricing after Anthropic’s valuation climbed from $61.5 billion in March 2025 toward $380 billion in early 2026 and a $965 billion Series H round in May 2026, when the company said annualized revenue had exceeded $47 billion. Anthropic confidentially submitted a draft IPO registration days after that financing. As of the end of June 2026, none of the Marshals Anthropic proceeds had been identified in the FTX bankruptcy estate, which reported $638 million from Justice Department-controlled assets in 2025—nearly all from Robinhood shares—and expects about $400 million more from the government without naming the Anthropic sale. The Justice Department says victim compensation is a priority and keeps disposal details confidential. The estate separately sold most of FTX’s own former Anthropic position in 2024 for about $1.3 billion.
