Anthropic publicly files IPO registration statement and plans to list on Nasdaq under ticker ANT
On October 26, 2026, Anthropic publicly filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission, planning to conduct an initial public offering of Class A common stock and apply to list on Nasdaq Global Select Market under the ticker ANT. The company issued an announcement on its website the same day confirming the above arrangements, while the number of shares to be issued and the price range remain undetermined. This public filing came after its confidential draft S-1 was filed on June 1, 2026.
The S-1 filing shows that Anthropic plans for the company and existing shareholders to jointly sell Class A common stock, with Goldman Sachs and Morgan Stanley among the lead underwriters. The filing also discloses its Public Benefit Corporation structure and governance arrangements related to the Long-Term Benefit Trust, and the entity of the co-founders will hold majority voting power through Class F shares.
Making the S-1 public is a procedural step that formally launches the roadshow and pricing process and must be completed at least 15 days before the roadshow. The market had previously widely reported its target valuation range and revenue growth data, but this is the first officially accessible registration document.

This public S-1 moves Anthropic from the confidential draft stage to a state that all investors can review, directly changing its capital path: from relying on private financing and large customer prepayments to public-market pricing and ongoing disclosure. In terms of governance, the founders’ voting power lockup and the long-term benefit trust arrangement continue its safety-first positioning, but also limit the control of ordinary shareholders, following a path similar to other dual-class technology companies. The capital concentration effect is becoming more evident — the underwriting lineup and the scale of the previously leaked computing contracts show that its financing capacity now depends heavily on continued cooperation from a small number of infrastructure suppliers and large cloud providers.
Cognitive laws
When a confidential draft becomes a public registration statement, pricing power moves from a limited group of informed investors to the entire market.
When locked voting rights and a public-benefit statement appear together, the safety narrative itself becomes a valuation constraint.
Once the 15-day pre-roadshow window opens, all previously leaked figures must be subject to the final revisions in the formal filing.
