Anthropic heads for the Nasdaq; IPO prospectus filed
Claude’s company will list its shares under the ticker symbol ANT. The aim is to raise up to 100 billion dollars
One of the biggest IPOs ever in the history of the US stock market is fast approaching. Anthropic has, in fact, just filed its prospectus for the listing. The document, an S-1 form submitted to the Securities and Exchange Commission, provides for the listing of Class A shares on the Nasdaq Global Select Market under the ticker symbol ANT.
The number of shares on offer and the price range are still to be announced
The sale will be carried out by both the company and certain existing shareholders, and Anthropic will receive nothing from the shares sold by the latter. The public filing follows the confidential one submitted in June, which had given the SEC time to review the accounts before making them available to investors.
Founded in 2021 by Dario and Daniela Amodei, along with a group of researchers who had left OpenAI (which is now also its main competitor), the company that develops Claude, is entering the market with growth figures that are virtually unprecedented. In the first half of 2026, revenue stood at $16.3 billion, compared with $1.2 billion in the same period the previous year. The net loss for the half-year was 80.7 billion. However, this figure should be interpreted with some caution. According to Reuters, a large part of this stems from a non-cash accounting adjustment linked to the increase in the estimated value of equity-convertible financing instruments. The same mechanism had weighed on the 2025 financial year, which closed with revenue of around 4.6 billion, twelve times that of the previous year, and a net loss of around 42 billion, 34 of which were attributable to that item. Excluding this item, the operating loss for 2025 stood at 8.06 billion, with 7.33 billion spent on computing and infrastructure. In any case, the prospectus warns that the company may not achieve profitability, or may fail to maintain it.
Factors in growth
This year’s growth is largely attributable to Claude Code, the assisted programming tool, and the Fable 5 and Mythos 5 models. In the third quarter, revenue rose to 16.8 billion, 45 per cent higher than in the second quarter. Today, the most likely valuation stands at around 1,500 billion dollars, compared with the 2,000 billion figures circulating in previous months. It is worth noting that in May, during the last private funding round of 65 billion, Anthropic was valued at 965 billion.
The scale of the operation remains unrivalled in recent times, with just one exception: that of SpaceX.
