Buying Anthropic stock: What investors need to know about the IPO and how you can participate in the AI market today

Updated June 16, 2026

Claude writes, analyzes, codes, and answers questions in seconds. That is exactly why many investors are now looking for Anthropic stock. The honest answer first: As of June 2026, Anthropic is a private company; there is currently no publicly traded stock. However, the IPO is in motion, which makes the questions of access, valuation, and risk particularly relevant right now.

Can you buy Anthropic stock yet?

No, you cannot currently buy Anthropic stock on the stock exchange. Anthropic is a private company. Therefore, as of June 2026, there is no official stock price, WKN, or ISIN for retail investors that would allow you to add Anthropic directly to your portfolio.

If you encounter a supposed Anthropic stock price online, it is most likely referring to estimates, secondary market prices, or reports on company valuation. This is different from a publicly traded stock price that you can buy or sell through your brokerage account.

The search is understandable, nonetheless. With Claude, Anthropic is one of the AI companies that many people now experience in their daily lives: when writing, analyzing documents, or programming. When you use a product, the investor question quickly arises: Can I invest in the company behind it?

Currently, the answer is: not directly through an Anthropic stock yet.

When will Anthropic go public? IPO status

As of June 16, 2026, an official date for the Anthropic IPO has not yet been set. However, it is known that on June 1, 2026, Anthropic confidentially filed an IPO registration, known as a draft S-1, with the US Securities and Exchange Commission (SEC). This makes Anthropic the first major AI lab to take this step.

Confidential filing means the company is starting the formal IPO process without making the documents fully public immediately. For you, this is an important signal because the process is becoming more concrete. At the same time, it does not yet result in a guaranteed date, a guaranteed valuation, or the ability to buy the stock on an exchange today.

The timing remains open. Anthropic and OpenAI are in a race to be the first major AI IPO. This market window is exactly what makes it so interesting: AI companies are growing rapidly, require enormous sums for computing power and research, and the capital market is trying to translate these expectations into valuations.

An IPO makes a private company visible. However, it does not automatically make it predictable.

How much is Anthropic worth? Valuation and revenue

At the end of May 2026, following a $65 billion Series H funding round, Anthropic was valued at approximately $965 billion post-money. Investors in this round include Altimeter, Dragoneer, Greenoaks, and Sequoia, among others.

The rise has been exceptionally fast: in March 2025, the valuation was around $61.5 billion, in February 2026 it was around $380 billion, and by the end of May 2026, it reached approximately $965 billion. This puts Anthropic ahead of OpenAI, which was valued at approximately $852 billion as of June 2026.

These figures reveal two things at once. First, the market has a great deal of confidence in Anthropic. Second, expectations are incredibly high. In private valuations, a small number of professional investors negotiate shares in a company, often with specific contractual terms. This differs from a stock market price, which is continuously determined by many buyers and sellers.

When it comes to revenue, a serious assessment remains intentionally qualitative: Anthropic is growing rapidly, but it is also investing heavily in research, product development, and computing infrastructure. This is crucial for AI labs, as every improved model requires talent, data, chips, and data centers. Growth can look impressive while capital expenditure simultaneously rises massively.

For you, this means: the valuation is a signal, but it does not replace your own risk assessment. Anyone looking only at the big number is missing the second half of the story.

Is there a Claude stock?

No, there is no Claude stock. Claude is the AI model family from Anthropic, which is the product many users are familiar with. The company behind it is Anthropic.

If Anthropic goes public, the company Anthropic would be listed. There would then be an Anthropic stock, not a separate IPO for Claude. This confusion is understandable, as products are often better known than the corporate structure behind them. It is similar with OpenAI: many people know ChatGPT, but it is the company that would count on the stock market.

The practical point is simple: anyone searching for a Claude AI stock is ultimately looking for Anthropic. And as of June 2026, Anthropic is still private.

Anthropic or OpenAI? The race in the AI market

Anthropic and OpenAI represent two of the most visible private AI companies in the world. Both are private, both are confidentially preparing for an IPO, and both shape the question of how investors can participate in the AI market before the companies are freely tradable on the stock exchange.

In terms of valuation, as of June 2026, Anthropic is ahead with approximately $965 billion compared to OpenAI's approximately $852 billion. OpenAI, however, has enormous reach in the daily lives of many users with ChatGPT. Anthropic scores with Claude, strong momentum, and a valuation that has risen sharply in a short period.

For investors, the comparison is important because it shifts the focus of the search. It is not just about which stock becomes tradable first. It is about whether you can participate in the private AI market before an IPO at all, through which channel that happens, and what risk you are taking on.

Can I participate in the AI market before the IPO?

You cannot currently invest directly in Anthropic via NAO. This is the clear distinction that is important: as of June 2026, Anthropic is not investable via NAO.

The ARK Venture Fund in the US does include Anthropic. However, this fund is not investable for EU citizens, so it is not a practical access route for most readers in Germany, Austria, and Switzerland. Accessible via NAO is the ARK Private Innovation ELTIF, which pursues a similar strategy. This ELTIF does not currently contain Anthropic, and there is no guarantee that Anthropic will be included in the future. Current holdings include OpenAI at approximately 26.5%, SpaceX, and Databricks, among others.

So, for those who want to participate in the AI market before the IPO, the ARK Private Innovation ELTIF offers a regulated way to do so via OpenAI. This is not a purchase of Anthropic stock and not direct individual stock ownership, but rather a fund investment in private innovation companies. You can find more about access via ARK here: ARK via NAO. If you are generally interested in pre-IPO companies, you might also find the article on SpaceX stock before the IPO be relevant.

What is an ELTIF and how does it differ from an ETF?

An ELTIF is a European fund structure that can provide retail investors with access to private markets—that is, companies and assets that are not traded on a stock exchange on a daily basis. An ETF, by contrast, typically tracks a publicly traded index and is generally tradable on a daily basis.

The difference is important for your planning: An ELTIF is geared toward the long term, invests in less liquid assets, and redemptions are only possible at specific times—quarterly and potentially subject to limits in the case of the ARK Private Innovation ELTIF, for example. In return, the fund bundles private companies within a regulated framework.

Conclusion: how to evaluate the Anthropic hype

The Anthropic IPO is bringing an extraordinary AI company into the spotlight. The question for you is whether and how you want to participate in the AI market before an IPO.

As of June 2026, you cannot buy Anthropic stock. There is no official listing date, no publicly tradable price, no WKN, and no ISIN. At the same time, the confidential SEC filing shows that the IPO process has begun. This is precisely why a sober assessment is worthwhile: valuation, timing, and access are three separate issues.

Anthropic is currently not investable via NAO. If you want to explore the private AI market, OpenAI is the accessible example within the ARK Private Innovation ELTIF. The fund bundles private innovation companies within a regulated framework, but remains a long-term investment with limited liquidity and the risk of loss.

In short: The hype generates attention. Your decision needs structure.
