Anthropic files IPO paperwork, proposes Nasdaq listing under ticker ANT
Key Facts
Anthropic filed paperwork on Monday to sell shares to the public for the first time, a step that sets the stage for a potential market debut next month, according to The Associated Press. The company said in its filing that it would list its shares on the Nasdaq Global Select Market under the ticker ANT. The filing moves the IPO process from expectations about when a prospectus might be published to a disclosed procedure, but does not set a trading start date or pricing terms. Reuters reported on October 22 that the company was moving toward a mid-November IPO, with a public prospectus potentially published late in the month, while warning that plans and timing could change. The Associated Press described the potential offering as one that could become the largest initial share sale ever.
Anthropic did not disclose in the filing how much money it intends to raise. Axios reported speculation that the company could seek to raise about $100 billion at a $2 trillion valuation, but those figures are not terms announced by the company. Reuters reported that investors had discussed a valuation close to $1.5 trillion, down from about $2 trillion that some had previously expected. Reuters linked the lower expectations to slower quarterly revenue growth in the third quarter, which disappointed some investors. Even so, revenue rose 45% to $16.8 billion in that quarter compared with the second quarter, after more than doubling from the first quarter to $11.6 billion in the second quarter.
Financial figures cited in reports on the prospectus show revenue expanding alongside large losses. Anthropic recorded revenue of $16.29 billion and a net loss of $80.75 billion in the first half of 2026, according to Axios. Reuters said an accounting charge for changes in the estimated value of convertible notes accounted for much of the loss, without representing cash operating expenses. Spending on computing capacity and infrastructure totaled about $9 billion in the first half of the year, compared with $2.3 billion in the same period of 2025, according to Reuters. The rising spending puts computing needs at the center of investors' assessment of the company's growth and future obligations.
Long-term obligations underscore the scale of the infrastructure needed to meet demand for the company's services. At the end of 2025, non-cancelable hosting and computing commitments totaled $54.6 billion, then total long-term commitments exceeded $417 billion by early 2026, according to Reuters. The commitments included 3.5 gigawatts of dedicated computing capacity. In a more recent report, Reuters said Anthropic had committed to spending at least $518 billion over a decade on cloud services, computing and infrastructure. These commitments show that the company's expansion depends on financing and operating enormous computing capacity alongside revenue growth.
Sales data also show significant reliance on platforms owned by companies that compete with Anthropic in artificial intelligence. The company's sales through Amazon and Google cloud marketplaces totaled about $2.16 billion in 2025, or 47% of its annual revenue, according to a Reuters analysis. Anthropic paid the platforms about $351 million in distribution fees that year, equivalent to nearly 16 cents for every dollar of sales through them. Both companies are Anthropic investors and computing suppliers, as well as competitors in the market. Alongside the concentration in sales channels, two unnamed customers each accounted for 12% of revenue in 2025, according to Reuters.
The regulatory process for the IPO began with a confidential filing on June 1, 2026, when Anthropic said it had submitted a draft S-1 registration statement to the U.S. Securities and Exchange Commission. The company said at the time that proceeding with the IPO depended on the commission's review, market conditions and other factors, and that the number of shares and their price had not been determined. The Associated Press expected a market debut next month, while the dates Reuters reported from people familiar with the matter remained targets subject to change. Details of the offering size, pricing and trading start date remain among the items awaited in the company's prospectus. On governance, Anthropic announced that it would allocate 5% of its shares to a new public-benefit fund, subject to shareholder approval, with the possibility of adding 2% for every 50% increase in the company's value above a specified baseline, at the board's discretion.
