Shares changed hands at around $30 each. The stake was spread across 38 buyers.
The largest single block, worth $500 million, went to ATIC Third International Investment, an entity linked to Abu Dhabi’s Mubadala.
On paper, the estate did well. Turning $500 million into approximately $1.34 billion delivered a profit of around $800 million.
By the time of the sale, though, FTX’s slice had shrunk. Its initial holding of about 13.56% after the investment had been diluted to roughly 7.84% to 8% of Anthropic’s shares as the AI company raised more money.
Anthropic’s march toward a trillion-dollar listing
Anthropic is gearing up to list on Nasdaq under the ticker ANT, with the debut projected for around November 19.
According to the company’s updated S-1 filing, it plans to price shares between $70 and $78. At the top of that range, the offering would imply a fully diluted valuation of approximately $1.4 trillion.
The IPO also comes with a concurrent $26 billion placement to firms including Google and Nvidia.
The listing follows a funding round in May 2026 that valued Anthropic at $965 billion.
After a 10-for-1 stock split, the position amounts to approximately 445.4 million shares, roughly 2.5% of Anthropic’s fully diluted share count.
Depending on where the stock ultimately prices and trades, that stake is now valued somewhere between $30 billion and $45 billion.
What this means
For FTX creditors, the gap between approximately $1.34 billion and a possible $30 billion or more is wide enough to sting.
The 38 purchasers, led by the Mubadala-linked ATIC Third International Investment, bought at around $30 per share and are now holding a position that the IPO math values many times higher.
A fully diluted valuation of up to $1.4 trillion would put the company in rarefied territory. The S-1 range is a target, not a guarantee, and IPO pricing can shift with market conditions right up to the listing date.
The key dates to watch are the final pricing and the projected November 19 debut.
