Anthropic has published details of its planned Nasdaq listing under the symbol ANT. Here is what the filing reveals about its finances, its risks and how control of the company may be protected.
On Monday 26 October 2026, Anthropic, the company behind the Claude AI models, published details of its planned stock market listing in the US. It will list on the Nasdaq under the symbol ANT and, according to the BBC, will be the first fully AI-focused company to go public. Its valuation is expected to exceed that of SpaceX, whose listing this summer was the biggest ever at an initial valuation of about $1.8 trillion.
For businesses that build on AI models, the filing is worth reading closely. It is the most detailed public account yet of how a frontier AI developer makes money, what it spends and what it thinks could go wrong.
What has and has not been disclosed
Anthropic has not yet said how many shares it will sell, the price range or the date of the listing. What it has published includes:
- Revenue of $16.3bn (£12.2bn) in the first half of 2026.
- Losses of more than $80.7bn over the same period, exceeding revenue.
- Around 90 pages of risk factors, covering everything from chip supply to legal liability for what its systems do.
Anthropic said it would often make forward investments "that may seem irresponsibly large at first glance", adding: "In general, we will aim to be bold but sane, and to win trust with a track record of successful bets."
Matt Orton of Raymond James Investment told the BBC that investors expected rapid growth alongside rapid losses, so the figures were no surprise, but that the filing would show where revenue growth is coming from.
An unusual warning to investors
Companies list risks in every prospectus, but few warn of risks to humanity. Anthropic's filing says advanced AI systems "could, if not developed, deployed, and operated with appropriate safeguards, oversight, and security measures, pose catastrophic or existential risks to humanity, particularly if such systems were misused, replicated, weaponised, or allowed to operate with a high degree of autonomy".
The more commercial risks it names include:
- reliance on a small group of cloud computing providers
- dependence on Taiwanese chipmakers already facing huge demand
- data centres concentrated in the US
- possible regulatory action over harms linked to its models, including use by children or people at risk of suicide
- uncertainty about where and how it might be held liable for actions its systems take
The same day, the owners of the rights to Elvis Presley's music sued Anthropic, accusing it of using hundreds of his songs to train Claude. The timing is a reminder that copyright litigation remains an open risk for every model developer.
How control of the company may be kept safe
One question many people are asking is how a mission-led AI company keeps control once its shares trade publicly, where any investor can buy in.
The BBC's report on the filing does not set out the share structure, and the full prospectus, with the number and classes of shares, is still to come. What is already public is the governance Anthropic set up before the listing:
- Public benefit corporation. Anthropic is a Delaware public benefit corporation, which means its directors must weigh its stated public benefit alongside shareholder returns, not profit alone.
- The Long-Term Benefit Trust. In September 2023 Anthropic announced an independent trust that holds a special class of shares. That class gives the trust the right to elect a growing number of Anthropic's board members, rising over time to a majority. The trustees are meant to have no financial stake in the company, so that board decisions keep its mission in view.
Many listed technology companies protect founders or long-term holders through classes of shares with different voting rights, so that a majority of the economic value can be sold while control stays with a smaller group. Whether Anthropic keeps the trust's board rights unchanged after listing, and how much voting power ordinary ANT shares will carry, are the details to check when the final prospectus is published. We will update this article when they are confirmed.
OpenAI and the wider market
Anthropic announced its intention to go public in June, and OpenAI quickly followed. A person familiar with OpenAI's plans told the BBC its listing is now expected early next year. Peter Andersen of Andersen Capital Management told Reuters the outcome of Anthropic's debut would be "fairly indicative of the sentiment" among investors about continuing to fund AI development.
What it means for businesses using AI
If you build products on Claude or any other frontier model, the filing is useful due diligence:
- Supplier concentration. The developer's own risks, from chips to cloud capacity, become your risks. Plan for a second model provider where your product depends on one.
- Spending and pricing. Losses on this scale suggest prices, rate limits and terms may change as listed companies come under pressure to show a path to profit. Keep contracts and budgets flexible.
- Liability. The filing itself says liability for AI actions is unsettled. Make sure your own terms, human review steps and logging cover what your AI features do.
At Webmasters LDN we build software and apps on several AI platforms and design them so that a change in one provider does not stop your product. If you would like to talk through your AI supplier risk, get in touch.
