Question
How much is FTX's old Anthropic stake worth now?
Short answer: About $43.4B as of 2026-11-02. FTX's old block is 445,392,400 Anthropic shares, 2.5% of the company by the share count in its S-1 (Oct 26, 2026), at the pre-IPO price of $97.51 a share. The FTX bankruptcy estate sold the shares in 2024 for $1.34B.
