FTX Anthropic Sale Raised $1.34 Billion; Stake Could Top $30 Billion

$1.34 billion was the cash outcome. FTX sold its Anthropic stake to 38 buyers. The same position could now carry a paper value of roughly $30 billion to $45 billion.

The shares changed hands at around $30 each. ATIC Third International Investment took the largest block, worth $500 million. The entity is linked to Abu Dhabi’s Mubadala and led the purchasing group.

The sale generated about $800 million in profit for FTX’s estate. The buyers’ collective position now sits far above FTX’s realized proceeds. That gap is where the story matters for creditors.

The comparison sets cash already received against a much larger prospective value. It does not change the $1.34 billion in sale proceeds. It does change how the conversion looks against the later valuation.

How dilution reshaped the sold position

FTX’s ownership had already shrunk. The estate held about 13.56% after investing in Anthropic. Later fundraising diluted that interest to roughly 7.84%–8%.

The current share count reflects a 10-for-1 stock split. The position covers about 445.4 million Anthropic shares. That equals roughly 2.5% of the fully diluted share count.

The buyers paid for the diluted ownership. They did not buy FTX’s original 13.56% stake. The S-1 still assigns their smaller holding a much larger valuation.

That lower percentage reflects Anthropic’s repeated capital raises before the sale, and it remains the relevant measure once the stock split is applied. The block buyers’ exposure is tied to the company whose shares they now hold, not the estate’s historic ownership percentage.

What Anthropic’s filing says about the IPO

Anthropic’s updated S-1 sets an IPO range of $70 to $78 per share. The company expects to debut around November 19. Nasdaq would list the shares under the ticker ANT.

At the top of that range, the offering implies a fully diluted Anthropic valuation of approximately $1.4 trillion, the reference point for the position’s estimated public value. That figure anchors the $30 billion-to-$45 billion estimate for the buyers’ holding.

The S-1 also outlines a concurrent $26 billion placement. Firms including Google and Nvidia would participate. The allocation would sit alongside the public offering.

The listing follows a May 2026 funding round. That round valued Anthropic at $965 billion, according to the updated filing. The proposed IPO introduces a higher public-market reference point.

The range remains a target, not a guarantee. IPO pricing can shift through listing day. Market conditions may move the final terms away from the S-1 range.

What changes for FTX creditors?

The practical distinction is simple. FTX realized $1.34 billion in cash. The buyers now hold a position that Anthropic’s IPO math values many times higher.

That difference creates no new cash for creditors after the sale. It changes the context for assessing the conversion. It also places a far larger prospective value beside the amount already realized.

No creditor payout timetable accompanies the reported figures. The $30 billion-to-$45 billion value remains a prospective mark. It depends on final pricing and trading after the debut.

The market structure is changing too. Private blocks changed hands at roughly $30 each. A Nasdaq listing would put the shares into public trading, replacing private block prices with a public quote.

Final pricing is the first concrete test. The projected November 19 debut is next, as the holding moves from private blocks to a listed equity with a public-market valuation.
