What happened

Key facts

  • Anthropic filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission for a proposed initial public offering.
  • The proposed offering is for Anthropic Class A common stock.
  • Anthropic has not determined how many shares it will offer.
  • Anthropic has not set a price range for the proposed offering.

The brief

Anthropic filed an S-1 registration statement with the U.S. Securities and Exchange Commission, setting out plans to list its Class A common stock on Nasdaq under the ticker ANT. The filing gives investors a view of the company’s financial position, governance structure and large commitments for computing resources as it prepares for a public offering.

Anthropic reported a net loss of $80.7 billion on revenue of $16.3 billion in the first half of the year. Those figures appear in the filing and give the prospectus a stark financial dimension alongside its account of the company’s business and planned listing.

The filing describes the company behind Claude; The Verge characterized the IPO plan as a bid to reach the public markets before OpenAI. The prospectus outlines five classes of common stock: A, F, E, T and N. Class F shares hold 50.1% of the company’s total voting power, while Class N holders are primarily strategic business partners.

Long-Term Benefit Trust and Founder LLC are named among shareholders with stakes above 5%. The structure therefore distinguishes economic ownership from voting influence, with the filing assigning a majority of voting power to Class F. The filing also details substantial agreements for computing capacity.

Anthropic’s commitments include $44.9 billion with Microsoft through 2033, at least $114.5 billion with Google through 2033, and $110 billion with Amazon over ten years.

It further describes a planned arrangement with SpaceX involving about $3.1 billion per month for access to Nvidia GPUs once all planned capacity is delivered, with the total potentially reaching $120.5 billion by 2029. The stated figures describe commitments and planned capacity, rather than a single immediate payment.

The Verge reported that Anthropic co-founder and chief executive Dario Amodei received nearly $18 million in compensation in 2025, mostly through stock and option awards.

That executive-pay detail sits alongside the filing’s disclosures of large infrastructure commitments and substantial first-half losses, giving prospective investors several distinct financial measures to assess. The market backdrop differs across the coverage.

India Today said volatility had led several companies to postpone planned listings, while the filing’s scale of compute commitments underscores the financial demands associated with Anthropic’s operations. Zee Business also reported that rival OpenAI had delayed its plan to go public in 2026, presenting Anthropic’s filing in contrast to that rival’s timing.

Zee Business reported a separate public-good commitment: Anthropic said a fund would initially receive 5% of its shares, subject to stockholder approval.

The company said that, combined with existing pledges from its co-founders and employees, roughly 20% of its shares would be dedicated to the public good, with possible additional contributions if specified valuation milestones are reached.

The filing’s governance provisions, financial disclosures and planned listing now place those commitments before investors as part of the company’s proposed move to public markets.

Why it matters

  • The filing moves Anthropic toward a public offering, but prospective investors cannot yet estimate its price, size or the ownership stake they could buy: the company has not set a price range or share count. Until those terms are disclosed, investors and analysts will have limited grounds to value the offering or assess how much capital it could raise.

What to watch next

  • Whether Anthropic proceeds with its stated Nasdaq listing under ticker ANT.
  • Whether stockholders approve the fund’s initial 5% share allocation.
  • Whether Anthropic makes further public-good contributions if it reaches the specified valuation milestones.
  • How the planned SpaceX capacity delivery affects the stated commitment, which could total $120.5 billion by 2029.

In September 2023, Amazon announced an investment of up to $4 billion and a cloud-computing partnership with Anthropic; in November, the companies expanded that arrangement, with Amazon committing a further $2.75 billion.
