Anthropic IPO: How to buy Anthropic shares
Anthropic, a rival to OpenAI and the startup behind the next-generation AI assistant Claude, could be preparing to go public. Backed by tech heavyweights including Amazon and Google, the US AI lab has seen its valuation surge into the tens of billions. With demand for AI infrastructure exploding and competitors like OpenAI shaping global markets, one question keeps coming up for Australian investors: when will Anthropic go public, and how can you buy shares when it does?
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 official IPO date as Anthropic has not filed to go public with the SEC. However, the company appears to be in early talks with lawyers to list on Wall St as early as 2026, according to the Financial Times.
A company spokesperson reportedly told the FT that no firm decisions had been made about the timing of an IPO, if it does happen.
What’s the expected Anthropic IPO share price?
The expected Anthropic IPO share price is unknown and won’t be set until the company files for an offering and works with underwriters. That said, recent private-market valuations give some sense of scale (see ‘Anthropic valuation’ below).
Anthropic valuation
Because Anthropic is not publicly traded we don’t have an exact market valuation for the company, however recent investment rounds give us an estimate.
Anthropic’s most recent valuation is around US$350B, according to unnamed sources speaking to CNBC in November, 2025. That’s a huge jump from its US$183B valuation in September, though at this stage it’s not been officially confirmed.
We also have an idea of Anthropic’s projected revenue. Its run rate revenue as of August 2025 was just over US$5B, up from around US$1B at the start of the year. This makes it one of the fastest growing firms in history.
Valuation timeline
- March 2025: Raised capital at post-money valuation of US$61.5 billion.
- September 2025: Raised US$13B in Series F – valuation jumped to US$183 billion.
- 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?
There’s no ticker symbol yet as Anthropic remains private. We’ll update this guide when the company announces a listing symbol.

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.
Claude’s latest flagship model, Claude Opus 4.5, is positioned as Anthropic’s most capable system to date, designed for demanding enterprise and developer workloads such as large-scale software engineering, complex “agentic” workflows and long-context reasoning. It delivers big improvements in coding and tool use, topping leading benchmarks for code generation and debugging while remaining more token-efficient than many rival reasoning models.
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.
