Anthropic IPO: How to buy Anthropic shares
Anthropic, the startup behind AI assistant Claude, has filed to go public. The IPO is expected to be bigger then SpaceX, which would make it the largest public-offering in history. Here's how Australians can invest when it lists.
What's the latest on Anthropic's IPO?
On October 26, Anthropic publicly filed its S-1 form with the U.S. Securities and Exchange Commission (SEC) to list on the Nasdaq.
According to Reuters, the company is targeting a more than US$2T valuation in a late November IPO, which would make it the largest-ever public offering.
The number of shares and the IPO price haven’t been set yet. Both are usually confirmed in the days just before a company lists.
According to the filing, Anthropic has applied to list Class A shares under the ticker $ANT, with Goldman Sachs and Morgan Stanley leading a syndicate of 22 underwriters. We’ll keep updating this guide as the details firm up.
What does Anthropic do?
Anthropic is an artificial intelligence company best known for developing Claude, a family of advanced AI language models designed to be safer, more controllable and more reliable than competitors.
The company focuses heavily on ‘constitutional AI’ – an approach that uses a set of rules to guide model behaviour toward safer outputs. Its customers include enterprises across tech, finance, consulting and customer support, and it is widely seen as one of OpenAI’s strongest competitors.
What’s the Anthropic IPO date?
There’s no confirmed IPO date yet. Now that the S-1 is public, a listing typically follows a few weeks after the SEC signs off. It’s expected the company will list on Wall St in late November 2026, just ahead of the U.S. midterm elections.
What’s the expected Anthropic IPO share price?
Anthropic said the number of shares to be offered and the price have not yet been set. This information likely won’t be made public until very close to the listing date.
That said, recent private-market valuations give some sense of scale (see ‘Anthropic valuation’ below).
Anthropic valuation
Anthropic is still private, so there’s no market valuation until it lists. What we do have is its last funding round and, for the first time, audited accounts.
The most recent raise was about US$65B across May and June 2026, valuing the firm near US$965B.
We also have some revenue and loss details. Revenue has gone from US$41M in 2023 to US$4.59B in 2025, growth of 1,088% in that year alone. It made US$16.29B in the first half of 2026, up 1,300% on the same period last year.
It’s still losing money on paper, with a net loss of US$41.97B in 2025 and US$80.75B in the first half of 2026. Most of that is a non-cash accounting charge rather than operating costs. Anthropic posted US$974M of operating income in the June 2026 quarter, its first operating profit.
Valuation timeline
- May 2026: Raised $65B, valuing the company at US$965B post-funding.
- March 2025: Raised capital at post-money valuation of US$61.5 billion.
- February 2026: Raised US$30B at a US$380B post-money valuation.
- November 2025: Valuation rumoured to be ~US$350B following investments from Nvidia (US$10B) and Microsoft (US$5B).
What is the ticker symbol for Anthropic?
According to the S-1 filing in October, Anthropic's ticker symbol is $ANT.

Can you buy Anthropic pre IPO?
In general, no – not as a typical retail investor. Anthropic remains private, and pre-IPO shares are only available through private markets / secondary marketplaces or to accredited investors.
Some private-market platforms may list bids or offers, but these tend to be illiquid, often risky, and are not the same as publicly traded stock.

More about Anthropic
Anthropic is a U.S.-based artificial intelligence company founded in 2021 by former OpenAI researchers, including siblings Dario and Daniela Amodei. The firm is best known for Claude, a family of large language models built using its “constitutional AI” approach, which aims to make AI systems more reliable, steerable and safer to deploy. Anthropic focuses on enterprise and developer use cases, offering tools for tasks like coding, customer support, knowledge work and data analysis.
With backing from mega tech firms, Anthropic has rapidly grown into one of the most valuable private AI companies in the world, with its models used by businesses across sectors such as tech, finance, consulting and government.
Anthropic’s model range runs across four classes: Mythos (including Fable), Opus, Sonnet and Haiku. Mythos is the most capable and is restricted to vetted organisations working in cybersecurity and life sciences, while Fable is the version available to everyone. Claude Opus 5.5, released in September 2026, is the workhorse for reasoning-heavy enterprise and developer work, and cut the cost of completing a task by around 40% compared with Opus 5.
Who owns Anthropic?
Anthropic was founded in 2021 by seven former OpenAI researchers, led by siblings Dario and Daniela Amodei. As of 2025, Anthropic is backed by major investors including Google, Nvidia, Microsoft and Amazon, who each have large stakes in the startup.
Who are Anthropic’s competitors?
Anthropic is frequently compared with other major players in generative AI, most notably OpenAI. Other competitors include large tech firms deploying their own AI models, smaller AI startups targeting enterprise AI services, and cloud/AI infrastructure providers.

How will Anthropic perform going public?
If Anthropic does go public, it’s likely to attract significant investor interest. The company has grown into one of the most valuable private AI labs in the world, backed by Amazon, Google, Microsoft and Nvidia, and demand for AI infrastructure is strong. That combination typically supports a high-profile IPO.
However, early trading could be volatile. Private-market valuations don’t always translate smoothly to public markets, especially when a company is still investing heavily in growth and not yet profitable. Investors will also be watching how Anthropic’s technology and customer base stack up against competitors like OpenAI and Google, and whether it can maintain momentum in a rapidly evolving field.
In short, Anthropic could debut strongly, but its long-term performance will depend on execution and its ability to stay competitive in the AI race.
