Is Anthropic publicly traded? Can I buy Anthropic stock?
Not yet. Anthropic is still a private company. It published its S-1 on October 26, 2026 and has applied to list on Nasdaq under the ticker ANT, but no shares trade until the IPO is priced, and no price or date has been set. Until then you can only get exposure indirectly, via public proxies like Amazon (AMZN) and Alphabet (GOOGL), or through accredited-investor secondary markets.
What is Anthropic's valuation?
Anthropic was valued at $965B post-money after its $65 billion Series H round closed on May 28, 2026. That makes it one of the most valuable private companies in the world, ahead of OpenAI's last reported valuation.
What is Anthropic's market cap?
Anthropic is private, so it has no public market cap. That figure only exists once a company's shares trade on an exchange. The closest equivalent is its most recent post-money valuation of $965B post-money, set by the $65B Series H in May 2026. Treat it as the nearest available proxy rather than a true market capitalization; a real market cap will only exist after an IPO.
How much revenue does Anthropic make?
Anthropic's annualized revenue run-rate reached about $65B (End Jul 2026), up from roughly $9B at the end of 2025, driven by enterprise adoption of Claude and Claude Code.
When will Anthropic IPO?
Anthropic has not set a date. Its public S-1, filed on October 26, 2026 after confidential review from June 1, 2026, leaves the price and the date blank, and an amended filing with third-quarter results and a price range has to come first. Reported timing: Roadshow from the week of November 9; trading before Thanksgiving (November 26). Anthropic has not confirmed it.
