The Anthropic IPO faces a bumpier road to the Nasdaq than the company might have hoped a week ago. The artificial intelligence company filed its public IPO paperwork on October 26, and within days several of its key partners reported quarterly results that added to market jitters about the cost of the AI buildout.
The Anthropic IPO plans a Nasdaq listing under the ticker ANT, aiming for a mid-November debut, according to reports of the filing. Reports have put the possible valuation at $1.5 trillion to $2 trillion, which would put it in the same league as SpaceX, which listed in June. The prospectus did not say how many shares Anthropic will sell or at what price.
The Anthropic IPO filing itself gave investors a great deal to weigh. Anthropic reported $16.3 billion in revenue for the first half of 2026, up about 1,300 percent from $1.16 billion a year earlier. It also disclosed a net loss of $80 billion for the same period, alongside hundreds of billions of dollars in compute commitments and more than 90 pages of risk factors. Investors are still waiting to see its third-quarter financials.
Anthropic IPO prospectus figures in detail
The compute commitments are the largest number in the Anthropic IPO filing. Anthropic disclosed future obligations of roughly $518 billion for compute in an earlier filing, covering data centers, equipment and cloud services. By the time it filed its S-1 on October 26, those commitments had grown to more than $600 billion across approximately eight partners, according to Reuters.
One of those commitments stands out. Anthropic is paying SpaceX about $1.25 billion a month for access to the Colossus data center in Tennessee, under a deal running through May 2029.
As of September 30, more than 1,900 customers each generated at least $1 million in revenue over the preceding 12 months, according to the filing as reported by VentureBeat. The question for investors is whether that revenue can cover commitments already running into the hundreds of billions of dollars.
Anthropic IPO timing and market jitters
The Anthropic IPO prospectus arrived in a tough week. Within days of its release, Microsoft, Google and Amazon reported quarterly results that added fuel to existing market jitters around the AI buildout. “Everybody’s still full steam ahead on AI, but all the things around it took an interesting turn this week,” Daniel Newman, chief executive of Futurum Group, told CNBC in an interview on Friday.
Newman said the hyperscalers’ results had “raised eyebrows” and created a new headwind in the market, which he described as “more doubt on capital structure.” The concern is not that AI demand has vanished. It is that the spending needed to meet that demand keeps rising, and investors are asking harder questions about how it will be financed.
The numbers from the partners showed both sides of that question. Microsoft cut its projected annual capital spending to $170 billion from $175 billion, while Alphabet held its guidance steady at a maximum of $205 billion and Amazon reaffirmed a projection of about $220 billion. Google reported negative free cash flow of $9.1 billion, contributing to a nearly 13 percent drop in its stock price on Thursday, according to CNBC.
On Friday, the Nasdaq Composite fell 2.9 percent, marking its first three-week losing streak since March. Nvidia and the broader semiconductor sector traded lower after Intel issued a weak forecast. The Anthropic IPO will be priced into a market that has just had its worst week in months, rather than the calmer market that greeted its filing on Monday.
Anthropic IPO outlook and the frozen market
Oracle, one of the biggest spenders on AI data centers, said at its investor day on Wednesday that it will limit additional fundraising in the coming years to $20 billion, and will turn cash flow positive in the second half of its next fiscal year. Analysts at Citizens wrote in a Thursday report that the announcement “put the biggest investor fear to rest,” the fear that funding the AI infrastructure buildout would require an open-ended increase in debt and equity issuance.
The wider IPO market has largely been frozen since SpaceX’s record offering in June, when total proceeds reached $85.7 billion after underwriters exercised their option to buy additional shares, according to Reuters. Biometric ring maker Oura, Australian AI data center operator Firmus and SK Hynix’s U.S.-based Solidigm subsidiary have all recently postponed or abandoned plans to go public.
Against that backdrop, Newman said the fear of missing out on a potentially “generational” company is real for Anthropic. Attention will now turn back from hyperscaler earnings to the Anthropic IPO, as investors assess how much risk they are willing to assume and at what price. The Anthropic IPO filing landed on October 26, with a mid-November debut the reported aim.
