Anthropic has stepped into the IPO spotlight with a filing that puts one of the AI industry’s biggest names on the public-market track. The company’s paperwork points to massive revenue growth, even as the costs of building and running frontier AI systems keep climbing fast.
Anthropic released its prospectus on Monday, setting the stage for a closely watched debut on Nasdaq under the ticker symbol “ANT” once the offering closes. The filing arrives after the company confidentially submitted its IPO plans in June, a move that signaled it was serious about opening the door to public investors.
The numbers in the filing tell a familiar Silicon Valley story: explosive expansion paired with eye-watering spending. Anthropic said compute and infrastructure will remain its biggest expenses for the foreseeable future, which makes sense for a company racing to train and serve large AI models at scale.
The company’s financial disclosures show how sharply those costs have moved. Compute and infrastructure expenses climbed from $433 million in 2023 to more than $2.5 billion in 2024, then surged past $7.3 billion in 2025, before jumping again in the first half of 2026.
Revenue has been moving just as aggressively, only in the opposite direction. Anthropic said sales rose from $386 million in 2024 to nearly $4.6 billion in 2025, while the first six months of 2026 brought in almost $16.3 billion, up from a little over $1.1 billion during the same stretch in 2025.
That kind of growth is exactly why Wall Street is watching this deal so closely. AI has become one of the market’s loudest themes, and Anthropic’s listing could become a fresh reference point for how investors value companies built around advanced models and the infrastructure behind them.
The company did not reveal how many shares it plans to sell or the price range it expects to target. That leaves a few blanks in the story, but it also underscores how early this process still is and how much attention the final terms could draw once they surface.
Anthropic, best known for its Claude chatbot, has already attracted serious money from major tech players. Amazon and Google were among its early backers, putting billions into the startup and helping provide the cloud resources it needs to train and run its systems.
The prospectus also leaned into Anthropic’s bigger pitch about where AI is headed. “We believe this abundance of AI will rapidly transform every sector of the global economy in ways greater than the impact of industrialization, electricity, semiconductors and the internet,” the company said.
At the same time, the filing did not pretend the technology comes without risk. Anthropic acknowledged concerns that AI systems could become misaligned or even improve themselves in ways that slip beyond human control, a warning that has become impossible for frontier labs to ignore.
CEO Dario Amodei has repeatedly argued that leading AI developers need to “pace the frontier” so models stay aligned with human interests. That position has put Anthropic in a slightly different lane from some rivals, even as the race for talent, scale, and market share keeps heating up.
The timing of the filing only adds more energy to the larger IPO conversation around AI. Elon Musk’s SpaceX saw a record-setting offering in June, while OpenAI also filed confidentially and has said it expects to move ahead with a public listing by early 2027.
Anthropic’s move now puts another heavyweight into the pipeline, and the reaction from investors, competitors, and customers will be watched closely. With capital needs rising and AI spending under constant scrutiny, the company’s next steps will be just as revealing as the filing itself.
