Anthropic Files Public S-1 for a Nasdaq IPO Under the Ticker ANT

AI · Published 27 October 2026

Anthropic has filed a public registration statement on Form S-1 with the US Securities and Exchange Commission, setting out plans for an initial public offering of its Class A common stock. The company’s news page, dated Monday 26 October 2026, says it intends to list on the Nasdaq Global Select Market under the symbol ANT. The number of shares and the price range have not yet been set.

The page names Goldman Sachs and Morgan Stanley as the sources for the preliminary prospectus, which is not yet available. Tech Insider, summarising the filing and citing Reuters and The Verge, says Anthropic had first filed confidentially in June. Wall Street expects a valuation of about $2 trillion at listing, but that is an expectation, not a figure from the filing.

The headline financial figures come from coverage of the filing by Yahoo Finance and Tech Insider, which agree on them. Anthropic reported about $16.3 billion in revenue for the first six months of 2026, compared with $4.6 billion for all of 2025. Second-quarter revenue was $11.6 billion, up from $4.7 billion in the first quarter.

The net loss for the same six months was $80.7 billion, against $42 billion for 2025. Tech Insider says the loss mainly reflects fair-value changes on convertible bonds, which it describes as largely non-cash. Yahoo Finance’s live coverage also reports operating income of $974 million in the second quarter, compared with a $1.7 billion operating loss in the first quarter.

Computing costs are a large part of the picture. Yahoo Finance reports $8.9 billion spent on rented computing in the first half and $482 million on the company’s own property and equipment. Anthropic says it is building its own data centres under an effort it calls Anthropic Direct. Tech Insider notes that a $518 billion infrastructure plan appeared in an earlier confidential draft and is not confirmed by the public filing.

Anthropic’s own page includes some of its language on the filing. It describes its legal purpose as “the responsible development and maintenance of advanced AI for the long-term benefit of humanity.” It also warns that its business faces an “evolving and uncertain regulatory and political environment,” and says the economic impact of AI by 2031 “could be even greater” than a $22.5 trillion forecast from IDC.

Why it matters: Anthropic is one of the most closely watched AI developers, so the filing gives investors, competitors and regulators a detailed look at its losses and spending. NPR’s headline on the filing describes an offering that could break records, though the size of the raise has not been confirmed. Tech Insider puts a figure of about $100 billion on it, but flags that as unconfirmed.

Several things remain unknown. The price range, the number of shares, the valuation at listing and the exact timing are not yet public. Yahoo Finance says the IPO is expected later this fall, and Tech Insider calls a listing before Thanksgiving unconfirmed. The figures here come from coverage of the filing, so readers should check the full S-1 for complete numbers.
