Anthropic
His old Anthropic stake
Short answer (2026-10-26): FTX's former Anthropic stake is 445,392,400 shares after the 10-for-1 split, 2.5% of Anthropic's roughly 17.78B fully diluted shares per its S-1 ↗ (Oct 26, 2026). At the pre-IPO price of $105.71 a share that is about $47.1B. The bankruptcy estate sold the shares in 2024 for $1.34B to 38 buyers. Widely cited figures of $75B to $80B used an outdated 7.8% stake.
In 2021 FTX put $500M into a small AI lab. The bankruptcy estate sold every share in 2024 for $1.34B. By the share count in Anthropic's S-1, those shares are now 445,392,400 shares, 2.5% of the company. At the pre-IPO price on 2026-10-26 that is $47.08B. Read the S-1 ↗

The math, step by step
- 2021: FTX invests $500M. It converts into 44,539,240 Series B shares at $11.23. Purchaser schedules ↗ list the exact count.
- 2024: the estate sells all of them at $30.0045 a share, the same price as Anthropic's own Series D that season: $884M in April, $452M in June.
- Sept 17, 2026: Anthropic splits its stock 10-for-1. The block becomes 445,392,400 shares. The dollar value doesn't change.
- Oct 26, 2026: the S-1 ↗ counts about 17.78B shares fully diluted. 445.4M of 17.78B is 2.5%.
- Today: 2.5% times the live pre-IPO valuation. Every $100B of Anthropic market value adds about $2.5B to the block.
| FTX's old block at | Per share | The block |
|---|---|---|
| FTX's entry, 2021 | $1.12 | $0.50B |
| Estate sale, 2024 | $3.00 | $1.34B |
| Series H round, May 2026 | $58.90 | $26.2B |
| Pre-IPO market, 2026-10-26 | $105.71 | $47.1B |
| If the IPO values it at $2T | $112.46 | $50.1B |
Per-share prices are after the split. Why the headlines said $75B to $80B: they multiplied the 2024 stake (7.8%) by a later valuation, but Anthropic kept issuing shares. See all 9 articles.
