Anthropic’s November listing hangs on a filing deadline as Wall Street looks to it to steady the AI trade

Anthropic is preparing to go public, and time is running out for it to file the paperwork needed for a listing in November^1,3. Jay Ritter, who leads the University of Florida’s IPO Initiative, said Anthropic still has some time if it wants to go public on that schedule¹.

The company will likely release its official offering statement, or S-1, any day now⁴. Wall Street is urging both Anthropic and OpenAI to complete their listings this year “before things get crazy”⁴. The Anthropic offering is expected to seek a $2 trillion valuation².

A report on a leaked version of the prospectus put Anthropic’s revenue at $16.3 billion, its net loss at $80.7 billion and its compute pledges at $750 billion⁷. Other coverage said investors are waiting for a filing on $600 billion of infrastructure commitments⁶. The two figures for the company’s commitments differ, and neither has been confirmed by a public filing^6,7.

Why it matters to investors

The listing would be a direct test of public-market appetite for an AI lab at a time when the AI trade is under strain. One commentary urged Anthropic to get on with its listing to soothe the AI trade². OpenAI has cut its valuation target amid investor hesitation, a contrast drawn in coverage of both companies’ plans⁶.

Early backers stand to gain. Coatue first backed Anthropic in 2025 at a $183 billion valuation and co-led the AI lab’s last two funding rounds⁵. A $2 trillion valuation would be more than ten times that earlier mark^2,5.

Questions about what buyers would own are part of the debate. Investors are weighing the company’s valuation, its ties to cloud hyperscalers and its unique governance³. Elon Musk’s companies get the benefit of the doubt from markets, but that may not be the case for Dario Amodei’s Anthropic⁸.

What to watch

The S-1 is the next marker. Its release will show the company’s revenue, losses and commitments in official form, and settle the gap between the $600 billion and $750 billion figures in circulation^4,6,7.

Timing is the second marker. Whether Anthropic files in time for a November listing will show how much weight it gives to the window that Wall Street wants it to use this year^1,4.

The reported loss is the third. A net loss of $80.7 billion, if confirmed, would put the price that buyers pay for growth at the centre of the offering^3,7. The report on the leak also described an expanding public-sector footprint for the company⁷.
