The story, neutrally told

Mixed · 2Anthropic, the developer of the Claude chatbot, made its IPO prospectus public on Monday 26 October 2026, filing an S-1 with the US Securities and Exchange Commission. Mixed · 2It plans to list on the Nasdaq under the ticker "ANT", with Goldman Sachs and Morgan Stanley leading the offering; the filing did not give the number of shares or a price range. Mixed · 2Net loss for the first half of 2026 was $80.7 billion on revenue of about $16.3 billion; City A.M. says around $72bn of the loss was non-cash adjustments tied to convertible debt and other financing instruments, and the company lost $42 billion in 2025.

Mixed · 2Revenue grew 1,368% year over year in the three months to 30 June, while cloud-service costs rose 300%; Anadolu Agency adds that the company told backers third-quarter revenue rose nearly 50% from the prior quarter to $16.8 billion, reaching profitability on an adjusted basis. Centre · 1Anadolu Agency reports the company plans to commit close to $800 billion to computing capacity over the next decade, and that the filing describes five share classes, under which seven founders keep 50.1% of voting power and the Long-Term Benefit Trust can appoint a majority of the board. Centre · 3Valuation reports differ: Anadolu says the filing targets $1.5–1.75 trillion, City A.M. says bankers reportedly target $1.5–2 trillion, and Reuters (via CNA) says some investors now value it near $1.5 trillion, down from about $2 trillion a week earlier. It was valued at $965 billion in May.

Centre · 3The debut is expected in November, with Anadolu saying after the US midterm elections but before Thanksgiving; NBC reports it is coming slightly later than expected as market moves give investors pause, and Hindustan Times, citing CNBC, says it could still be delayed. Mixed · 2The filing's risk factors cover safety, computing infrastructure, regulation and AI models that could show "self-preserving behaviors" such as attempts to "resist shutdown"; it also warns that negative media coverage of AI's societal impacts could harm its business and lists copyright lawsuits it says it will defend. Centre · 3Context: global equities have sold off over doubts about debt-funded AI spending, smaller IPOs have been delayed, and rival OpenAI filed confidentially for an IPO in June and is expected to list by early 2027; Anthropic itself filed confidentially in June. Outlets give differing figures for SpaceX's June IPO ($75bn per Reuters/CNA and NBC; $85.7bn per Hindustan Times citing CNBC; $86bn per Just the News citing AP).

Every sentence links to the reporting it rests on. The pill in front of each says where its sources sit: Left, Centre or Right when one side supplies at least half of them, Mixed when they are evenly split. The number is how many outlets it cites.
