Anthropic files publicly for Nasdaq listing under ticker ANT

Anthropic, the company behind the Claude chatbot, has publicly filed for a stock market listing in the United States. According to the Guardian, the company will list under the symbol ANT and confidentially filed with US financial regulators for an initial public offering in June ^[1]. The Verge reports that the filing is an S-1 prospectus lodged with the Securities and Exchange Commission, and that Anthropic plans to list on the Nasdaq exchange ^[2].

What the filing shows

The prospectus gives the first audited look at Anthropic's finances. The Guardian reports revenue of $41m in 2023, $386m in 2024 and $4.585bn in 2025, then $16.286bn in the first six months of 2026 alone ^[1]. The same filing discloses a net loss of about $80bn for the first half of this year ^[1]. The Verge puts the figure at $80.7bn and says, citing earlier reporting by the Wall Street Journal, that most of the loss comes from accounting charges linked to notes the company issued for funding ^[2].

Anthropic told investors it had raised $141.1bn by the end of June and had taken on $6.2bn in debt while building out its infrastructure ^[1]. It has also set out large computing commitments, including about $3.1bn a month to SpaceX for access to Nvidia chips once planned capacity is delivered, and at least $114.5bn with Google through 2033 ^[2].

A business-focused customer base

Unlike OpenAI, which has courted everyday consumers, Anthropic has focused on businesses as its main paying customers, the Guardian notes ^[1]. As of 30 September the company said it had more than 14,000 enterprise customers, with more than 1,900 spending $1m or more and about 250 spending $10m or more ^[1]. A quarter of revenue comes from its top five customers, though no single customer is more than 10% of the business ^[1].

Risks the company itself lists

The filing runs to more than 90 pages of risk factors, according to the Guardian ^[1]. Anthropic warns that safeguards on its most capable models are "incomplete, may be outdated in light of evolving threat models" and could fail ^[1]. It also flags unfavourable outcomes in copyright disputes over how its models are trained, and the risk of "catastrophic" AI incidents that, it says, no single insurer could underwrite ^[2].

The Guardian also reports that Anthropic is in a dispute with the Trump administration over the use of its products in warfare, which led to the company being designated a supply chain risk and barred from contracting with military agencies. The company has challenged that designation ^[1]. Valuation figures are not Anthropic's own: the Guardian says analysts and investors have valued the company at more than $1.5tn ^[1].

What it means for businesses

For companies that already rely on Claude, the filing offers something rare: audited figures on the supplier's growth, losses and spending obligations. The scale of the computing commitments shows how much capital the leading AI providers need just to keep serving customers. Buyers may want to ask how pricing and availability could be affected by the demands of public investors.

The listing is also being treated as a test of the AI boom's financial viability, the Guardian says ^[1]. Anthropic describes AI as potentially able to accelerate science and economic growth, but also lists risks it says it must navigate ^[2]. Readers should treat the prospectus as the company's own account and read it alongside independent analysis.
