What SBF's Anthropic investment would be worth today

By · Published by Everything Blog

In short

Major media outlets including Forbes and The Wall Street Journal mistakenly applied FTX's 2024 ownership stake of 7.8% to 8% to subsequent valuation increases.

The Wall Street Journal, Forbes and Benzinga all multiplied FTX's 2024 stake (7.8% to 8%) by a later valuation. Anthropic kept issuing shares, so the stake kept shrinking.1 Nobody did it on purpose. Dilution is easy to miss.
