Anthropic, the artificial intelligence company behind the Claude chatbot, has filed to go public in the United States, setting the stage for a potential record-breaking stock market debut as it warns investors that advanced AI could pose catastrophic or existential risks to humanity. The company filed its registration statement with the US Securities and Exchange Commission on October 26, 2026, and plans to list on the Nasdaq under the ticker symbol ANT.
The proposed offering could value Anthropic at between $1.5 trillion and $2 trillion, according to media reports, potentially surpassing SpaceX’s initial public offering valuation of approximately $1.77 trillion. However, Anthropic has not disclosed its target valuation, the number of shares to be offered or the final price range. The listing timetable remains subject to regulatory review and market conditions.
The filing provides a detailed picture of the financial pressures accompanying Anthropic’s rapid growth. The company generated $16.3 billion in revenue during the first half of 2026, up sharply from $1.2 billion in the same period last year. However, it reported a net loss of $80.7 billion, largely driven by a non-cash accounting adjustment reflecting the increased fair value of its convertible notes and other financing instruments.
Anthropic’s operating loss was considerably smaller at $693 million during the six-month period, although the company warned that substantial investment in computing infrastructure, research and product development could keep costs elevated. Its plans rely heavily on cloud computing providers, advanced semiconductor manufacturers and data centres, exposing it to supply constraints and large future financial commitments.
The company’s prospectus also contains unusually extensive warnings about the potential dangers of its technology. Anthropic said advanced AI systems could cause severe harm if developed or deployed without appropriate safeguards, oversight and security measures. It highlighted risks involving misuse, highly autonomous systems, cybersecurity threats and the possibility that increasingly capable models could behave in ways that are difficult to monitor or control.
The disclosures place AI safety at the centre of the investment case. Anthropic has built its public identity around developing AI responsibly, but its filing acknowledges that commercial pressure to produce more capable models could outpace the development of effective safety measures. The company also faces potential regulatory action and legal liability if its products cause harm.
Competition adds another layer of uncertainty. Anthropic faces rivals including OpenAI and Google as technology companies race to develop advanced AI models and attract enterprise customers. Its success depends partly on maintaining technological leadership while ensuring that the cost of computing and infrastructure does not undermine its financial position.
The company was founded in 2021 by chief executive Dario Amodei, his sister Daniela Amodei and five other co-founders, several of whom previously worked at OpenAI. Its Claude products have gained traction among businesses seeking AI tools for coding, research, analysis and workplace automation.
Anthropic has also highlighted AI’s potential benefits, including accelerating scientific research, improving medical discoveries and automating complex tasks. It argues that advanced systems could help researchers make progress against diseases such as cancer and Alzheimer’s disease, although these outcomes remain prospective rather than guaranteed.
For investors, the IPO will offer an opportunity to assess one of the leading AI developers through public financial disclosures. Its eventual valuation will depend on demand for the shares, growth prospects, infrastructure costs, competition and the company’s ability to manage the safety risks it has acknowledged.
