SBF's $500M Anthropic stake would be worth ~$37B at expected IPO price

Per the FT, SBF's Alameda Research Ventures bought nearly 14% of Anthropic in 2021 at a $4B valuation, investing $500M that helped the lab hire researchers and train its first models. After FTX collapsed and SBF was convicted of fraud, the bankruptcy estate sold the stake in 2024 for about $1.3B — it would now be worth roughly $37B at next week's expected IPO price.
A similar story with Anysphere (Cursor): Alameda put $200K into its April 2022 pre-seed round for 5%, and the estate sold it for the same $200K in 2023. At Anysphere's $60B valuation, that 5% would be worth about $3B.
