Anthropic stock & IPO, answered

No. Anthropic is a private company. It filed a confidential draft S-1 with the SEC on June 1, 2026, the first formal step toward an IPO, but no shares trade publicly and no ticker has been assigned. Reports put the listing on Nasdaq in November 2026; Anthropic has not confirmed a date.

Not directly. Until the IPO, exposure through an ordinary brokerage account is indirect: listed backers such as Amazon (AMZN) and Alphabet (GOOGL), which own sizeable stakes. Accredited or professional investors can sometimes buy pre-IPO shares on secondary platforms. Our how to buy guide covers both routes.

Anthropic has not announced a date. It filed confidentially on June 1, 2026, and reports in September 2026 said the listing had moved to November 2026. The next public milestone is the public S-1, which has to appear at least 15 days before the company starts marketing its shares.

Unknown. A ticker is usually revealed in the public S-1 or shortly before pricing. We'll update the site the moment one is confirmed.

Possibly, but in small amounts at best. Most shares in a large IPO go to institutional investors; individuals get access only through brokers that receive an allocation, which depends on the country and the broker. Once trading starts, anyone with a broker that offers the exchange can buy at the market price.

Anthropic was valued at $965B post-money after its $65B Series H closed on May 28, 2026, making it the most valuable private AI company in the world. In March 2025, its Series E valued it at $61.5 billion.

Anthropic has no market cap because it is private: a market capitalization only exists once shares trade on an exchange. The nearest equivalent is its latest post-money valuation of $965B post-money. That is a negotiated round price, not a live market value, so treat it as the closest proxy rather than a true market cap.

Anthropic's annualized revenue run-rate was about $65B at its latest reading (End Jul 2026), up from about $9B (End 2025 (est.)). Run-rate annualizes a recent month rather than adding up a year, so it can run ahead of recognized revenue. The public S-1 will show audited quarterly revenue for the first time.

By selling access to its Claude models. Developers and software companies pay per token through the API and the big cloud platforms, individuals and teams pay monthly subscriptions, and large organizations sign enterprise agreements. Business customers bring in the large majority of revenue, and Claude Code, its coding agent, is its fastest-growing product.

Not yet on a GAAP basis. Figures from its draft prospectus, reported by Reuters in September 2026, show an operating loss of about $8 billion in 2025 and a net loss of about $42 billion, most of it a non-cash accounting charge. As revenue surged in 2026, Anthropic was reported to expect a second straight quarter of adjusted operating profit, a measure that leaves out costs such as stock-based compensation. The public S-1 will confirm the figures.

Its founders and employees, strategic backers led by Amazon and Alphabet, and a long list of investment funds. The exact split has never been published. No single shareholder controls the company: an independent Long-Term Benefit Trust elects a majority of the board, and neither Amazon nor Google has a board seat.

Amazon and Alphabet are the largest strategic backers, followed by Microsoft, Nvidia and AMD. The Series H was led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, and earlier rounds were led by firms including GIC, Coatue, ICONIQ, Fidelity, Lightspeed and Spark Capital.

Neither has published a current figure. Court documents in 2025 put Google's stake at about 14%, capped at 15% and without voting rights. Amazon has never disclosed its percentage. The S-1 should list every holder above 5%.

Amazon (AMZN) and Alphabet (GOOGL) are the closest, because they own the largest stakes and supply much of Anthropic's computing power. Microsoft, Nvidia and AMD have smaller investments and sell Anthropic chips or cloud capacity. In every case Anthropic is a small part of a much larger company, so these are diluted bets on it.

Only in limited ways. Shares occasionally change hands on secondary marketplaces and through special-purpose vehicles, usually restricted to accredited or professional investors, with high minimums and fees. Private companies usually limit who can buy their shares, so be wary of any offer that promises easy access.

Seven former OpenAI researchers founded it in 2021: Dario Amodei, the chief executive, Daniela Amodei, the president, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Chris Olah. It is based in San Francisco.

Claude is Anthropic's family of AI models and the assistant built on them. It comes in tiers (Haiku, Sonnet, Opus and Fable) and is used through the Claude apps, the Claude Code coding agent, and the API, which other companies build into their own products.

An independent body set up in 2023 whose trustees have no financial stake in Anthropic. It holds a special class of shares that lets it elect directors, and since April 2026 its appointees have been a majority of the board. Anthropic is a public benefit corporation, and the Trust is meant to keep that public benefit in view as the company grows.

On the latest figures, Anthropic is valued at $965B against OpenAI's $852B, and its run-rate revenue of $65B compares with about $40B for OpenAI. That puts Anthropic at about 15 times revenue versus about 21 times for OpenAI. OpenAI has far more consumer users through ChatGPT; Anthropic earns most of its money from businesses.

The cost of compute and the multi-year capacity it has committed to, price competition from OpenAI, Google and open-weight models, dependence on a few large API customers, a dispute with the Pentagon that has split the courts, and lawsuits over training data. The public S-1 will set out the risks in Anthropic's own words.
