Anthropic publicly filed for a Nasdaq IPO Monday under the ticker "ANT," disclosing $16.29 billion in first-half revenue — up 1,304% year over year — alongside an $80.7 billion net loss and ongoing legal battles with the U.S. Department of Defense.
Anthropic publicly filed for an initial public offering Monday, submitting a Form S-1 with the Securities and Exchange Commission and revealing $16.29 billion in revenue for the six months ended June — a 1,304% increase from $1.16 billion during the same period a year earlier.
The company plans to list on the Nasdaq under the ticker symbol "ANT," with Goldman Sachs and Morgan Stanley serving as lead underwriters. The filing follows a confidential submission to the SEC in June that gave regulators time to review the company's financials before they became available to the public.
Anthropic also disclosed a net loss of $80.7 billion in the first half of 2026, a figure that underscores the enormous cost of building and operating frontier AI systems. The filing lists more than 90 pages of risk factors, with OpenAI and Google named as primary competitors.
CEO Dario Amodei co-founded the company in 2021 alongside a small group of researchers who departed OpenAI. Growth in 2026 has been driven largely by the AI coding tool Claude Code and by flagship models including Claude Fable 5 and Mythos 5, the filing shows.
The S-1 also shed new light on the ownership stakes held by two of its largest backers. Alphabet is set to hold a larger share than previously disclosed publicly, and the filing details commitments from Amazon and Microsoft, who has separately been supplying cloud infrastructure to Anthropic as part of a broader AI buildout.
Anthropic's offering arrives against a challenging backdrop. So-called neoclouds — specialized AI infrastructure providers including CoreWeave and Nebius — have lost over 30% of their value in October as concerns about data center credit risk have mounted. Wall Street has grown increasingly anxious over whether enterprise spending on AI services will ultimately justify the trillions of dollars in projected infrastructure costs.
The S-1 also flagged a serious regulatory risk. Anthropic warned investors that ongoing disputes with the Trump administration and the U.S. Department of Defense could result in "material revenue losses or business disruptions." The Pentagon labeled Anthropic a "supply chain risk to national security" in a decision that triggered litigation in two separate courts.
A California federal court ruled in Anthropic's favor, finding the Pentagon's actions were "retaliatory acts meant to punish" the company and that they violated Anthropic's First and Fifth Amendment rights. The D.C. Circuit Court of Appeals, however, ruled for the Department of Defense, finding the supply chain risk designation permissible under the Federal Acquisition Supply Chain Security Act. Anthropic said in the filing it is "evaluating its next steps" and has asked the full D.C. Circuit to rehear the appeal. On Monday, the U.S. government filed a notice of appeal seeking to invalidate the California district court's ruling.
On the infrastructure side, Anthropic disclosed that its computing pool spans Nvidia GPUs, AMD GPUs, AWS Trainium chips, and Google TPUs, which it treats as a "single fungible pool." The company said it routes workloads to whichever chip offers the best efficiency at a given moment. "Our multi-chip compute approach provides us with substantially greater chip access than relying on one platform and enables us to opportunistically capture the price-performance benefits of each chip family and generation," the company said in the filing.
The offering, if completed, would follow SpaceX's Nasdaq debut earlier this year — by far the largest IPO on record, raising $85.7 billion. SpaceX shares finished last week slightly below where they opened in June.
Matt Witheiler, head of late-stage growth for private markets at Wellington Management, told CNBC's "Squawk on the Street" that Anthropic's enterprise focus had been central to its trajectory. "The scale at which they've been able to capitalize on the enterprise opportunity is really something that's been impressive," Witheiler said, adding that Amodei and his team are "trying to build the next generation of great enterprise company."
With the filing now public, attention will turn to the roadshow and whether institutional appetite can absorb a company carrying both extraordinary revenue growth and extraordinary losses — in a market that is still deciding what AI profitability actually looks like.

SpaceX has closed $40 billion in debt financing to acquire Nvidia GPUs, with the chips expected to arrive in the first and second quarters of 2027. Elon Musk warned that more than 200 neocloud companies face failure as AI debt markets tighten.
SpaceX is in talks to access as many as 80,000 cell sites, Wall Street analysts say the move — combined with a recent 800 MHz spectrum buy — signals the company is pursuing full owner economics in its challenge to AT&T, T-Mobile, and Verizon.
