Anthropic, the AI safety firm, filed a confidential draft S‑1 with the SEC today, signaling a potential IPO. The filing opens a path to public markets once the regulator clears the paperwork. Market timing and pricing will still hinge on conditions, leaving the exact share count and offer price undecided for investors soon.

The move follows Anthropic’s recent $65 B Series H raise, valuing the company at $965 B post‑money. That funding round, led by Altimeter, Dragoneer, Greenoaks and Sequoia, underscored investor confidence in its Claude model line, now upgraded to Opus 4.8 with stronger coding and agentic performance across enterprise applications and research in Europe and North America today and growth.

Beyond the IPO, Anthropic is expanding its footprint with a new Milan office, the sixth in Europe, to support Italian enterprises and research labs. The studio will host developers and AI safety teams, reinforcing the company’s strategy to blend commercial deployment with rigorous safety experimentation across borders for global customers and regulators in 2026 and beyond.

Regulators will review the filing under Rule 135 of the Securities Act, ensuring the disclosure is complete before any sale. Until approval, the document remains confidential, and no public offer will take place. Stakeholders await the SEC’s decision, which will determine whether Anthropic can monetize its advanced AI platform for investors and shareholders in 2026.
