Anthropic Seeks Record $88.5 Billion for Public Market Debut

Anthropic is seeking up to $88.5 billion in a planned IPO and concurrent private placement, potentially the largest-ever fundraise tied to a public-market debut.

The San Francisco AI company submitted an updated S-1 on Tuesday, disclosing a proposed $70 to $78 share-price range, an offering size and a fully diluted valuation of up to $1.4 trillion.

How large could the IPO be?

Anthropic plans to sell just over 800 million shares at $70 to $78 each in the IPO. At the high end, the company would raise about $62.5 billion, making the deal the second-largest IPO behind SpaceX’s $75 billion offering, according to the filing and Crunchbase’s comparison.

The filing’s footnote puts the total offering at 825 million shares. Selling shareholders hold 23.6 million of those shares, leaving just over 800 million for Anthropic to sell.

How much comes from the private placement?

Anthropic expects to raise another $26 billion through a private placement scheduled to close immediately after the IPO. AMD, Broadcom, Google, Micron Technology, Microsoft, Nvidia and TSMC are named investors in the transaction.

Together, the IPO and placement could produce $88.5 billion in proceeds and set a record for capital tied to a public-market debut. Anthropic expects to use the capital for expensive expansion and infrastructure investment, according to the offering documents.

The company expects to make its Nasdaq debut later this month under the ticker symbol ANT. The structure places the public-market valuation test and a planned $26 billion corporate capital raise around the same listing.

Why did valuation expectations fall?

A MarketScreener report said investors had been forecasting a valuation closer to $2 trillion. The updated filing’s $1.4 trillion ceiling sits below that earlier expectation, which MarketScreener linked to concerns about slowing revenue growth.

At the maximum, Anthropic would rank behind only SpaceX’s June debut by valuation among public-market debuts, according to Crunchbase. The lower target narrows investor expectations without displacing the company from the top two.

How fast has Anthropic grown?

Anthropic updated its financial disclosures for results through September 2026. Revenue reached $33.2 billion for the first nine months, up from $2.5 billion in the same period a year earlier.

Anthropic says it has “the fastest enterprise adoption of any technology in history.” It says revenue rose from zero at commercial launch in the first quarter of 2023 to $17 billion in the three months ended Sept. 30, 2026.

The disclosure gives investors two tests at the IPO: the durability of revenue growth and the gap between operating improvement and the wider net loss. Both bear directly on the proposed $1.4 trillion valuation.

How large are the losses?

Anthropic remains unprofitable, according to the updated disclosures. It reported an operating loss of $1.3 billion for the first nine months, down from $5.2 billion a year earlier, while its net loss widened to $104 billion from $25.1 billion.

The disclosed figures pair a narrower operating loss with a much wider net loss. That divergence becomes a central issue for investors weighing a $1.4 trillion valuation against current losses.

What has to happen next?

The proposed $70 to $78 range is the next concrete test for the valuation. A sale near the high end would put the IPO near $62.5 billion, while the $26 billion placement would bring the combined target to $88.5 billion.

Anthropic must convert those plans into a completed IPO and placement while investors assess $33.2 billion in nine-month revenue against a $104 billion net loss. The coming debut will show whether public investors will fund Anthropic’s expansion at the scale implied by its filing.
