Anthropic IPO plans moved into public view on October 26, 2026, as the Claude developer unveiled its US listing filing and details of its leadership and governance. The company is targeting a mid-November debut, but the offering remains proposed and its registration statement has not yet become effective.

Key Takeaways

  • Anthropic intends to list Class A common stock on Nasdaq under the symbol ANT.
  • The offering’s share count and price range have not yet been determined.
  • The leadership includes former OpenAI executives, alongside recruits from finance, cloud infrastructure and enterprise software.

Anthropic IPO terms remain unfinished

Anthropic’s announcement of its proposed Class A share offering confirms that it filed a Form S-1 with the US Securities and Exchange Commission and intends to list on the Nasdaq Global Select Market under ANT.

The number of shares and proposed price range remain undetermined. The company also said the registration statement had not yet become effective, meaning the securities cannot be sold and offers to buy cannot be accepted before effectiveness.

The targeted mid-November listing is therefore a planned timetable, not a completed or guaranteed market debut.

Founders lead research as newer executives broaden operations

Anthropic’s founding team remains central to its leadership. CEO Dario Amodei previously served as OpenAI’s vice president of research, while president and board chair Daniela Amodei was OpenAI’s vice president of safety and policy and earlier led risk operations at Stripe.

Other co-founders oversee scientific research, compute, policy, interpretability and architecture. Their backgrounds include work on GPT-3, AI research at OpenAI and Google, and academic physics.

More recent appointments span finance, infrastructure and commercial operations. Chief financial officer Krishna Rao joined in 2024 after serving as CFO of Fanatics Commerce. Chief technology officer Rahul Patil joined in 2025 following senior roles at Stripe and Oracle. Chief commercial officer Paul Smith also joined in 2025, having been a special adviser at ServiceNow.

Board directors and trustees have separate roles

Beyond Daniela Amodei, board members include former Microsoft CFO Chris Liddell, Novartis CEO Vas Narasimhan, Spark Capital general partner Yasmin Razavi and Netflix co-founder Reed Hastings.

The filing also identifies a separate group of Long-Term Benefit Trust trustees who balance Anthropic’s goals as a public benefit corporation. They include trust chair Neil Buddy Shah, Richard Fontaine, Christopher Stubbs and former Federal Reserve chair Ben Bernanke. These trustees are listed separately from the company’s board directors.

Next milestone

The next regulatory milestone is effectiveness of the registration statement; the offering’s share count and price range also remain to be determined.
