Anthropic IPO: When will its stock hit Nasdaq?

Anthropic, the AI firm responsible for the Claude model, has submitted paperwork to the Securities and Exchange Commission (SEC) for an anticipated initial public offering (IPO). The company announced on October 26, 2026, its intention to trade its Class A shares on the Nasdaq Global Select Market using the ticker symbol ANT. This IPO is contingent upon approval from the SEC, and the shares cannot be traded until the registration statement is officially effective.

The registration document outlines Anthropic's intention to list on Nasdaq with the ANT ticker, although the exact number of shares being offered and the proposed price range have not been specified. The total amount Anthropic will raise will hinge on these factors, along with the shares sold by the company and existing shareholders.

The filing provides potential investors with a deeper insight into Anthropic's financial history, operations, and potential risks. In the first half of 2026, Anthropic reported an operating loss of $693 million. This figure is different from the headline net loss, which was heavily influenced by fluctuations in the value of financing instruments.

To fuel its growth, Anthropic has invested heavily in its computing infrastructure and the necessary capacity to train and run its AI models. By the first half of 2026, the company had spent around $9 billion on such infrastructure, a significant increase from $2.3 billion in the same period of 2025, according to Reuters' analysis of the prospectus.

Further, Anthropic anticipates annual expenditures of at least $265.6 billion in cloud computing, computing capacity, and infrastructure in the years ahead, as indicated in its public S-1 filing. Anthropic's planned IPO follows a trend among tech companies seeking various methods to raise capital, from private funding rounds to public listings.

While Anthropic is on the path to a public offering, its AI competitor OpenAI has chosen a different path, opting for private funding. In September 2026, Nairametrics reported that OpenAI was seeking $30 billion in additional funding, aiming for a valuation of $1.4 trillion, as it postponed its IPO plans to accumulate more capital for expansion.

Nonetheless, securing a listing only marks the beginning, as subsequent performance on the stock market will also impact investor returns. In July 2026, Nairametrics reported that SpaceX's shares declined below their $135 IPO price within two months of its debut on the market.
