The filing puts Anthropic in a race with OpenAI, which has also filed but not announced a market date. SpaceX began trading on June 12.
The full financial details of the IPO will be released at least 15 days before the company’s roadshow to institutional investors. Investors will then be able to see revenue figures, user growth, losses, and risk factors.
Anthropic’s annualized revenue reportedly reached $47 billion as of early May 2026, driven by growing enterprise demand for its Claude models.
Claude’s Market Position
Claude was released in 2023, several months after OpenAI’s ChatGPT. As of March 2026, Claude held 10% of website visits among leading AI platforms, according to market intelligence firm Sensor Tower. ChatGPT led with 50%, down from 66% in July 2025. Google’s Gemini held 22%.
Anthropic says AI capabilities are improving fast. The company estimates that the number of tasks AI can complete on its own is doubling every four months. In a blog post titled “When AI builds itself,” the company said Claude can now take an underspecified engineering problem and solve it at or above human cognitive levels.
Who Can Invest Now
Three public companies offer indirect exposure to Anthropic before the IPO.
Alphabet has committed to invest up to $40 billion in Anthropic and reportedly owns around 14% of the company. Anthropic has also committed to spend $200 billion over five years on Google Cloud services.
Amazon has committed up to $25 billion in new investment, with a potential total cash commitment of $33 billion. Amazon’s original $8 billion stake had grown to a fair value of $60.6 billion as of February. Anthropic plans to spend nearly $100 billion on AWS over the next decade. More than 100,000 customers already run Claude models on AWS.
Salesforce holds an Anthropic stake currently valued at around $5 billion. It has integrated Claude into its Agentforce 360 enterprise platform. Anthropic also uses Slack and Sales Cloud internally, with Slack usage rising fivefold in the first quarter.
CEO Calls for AI Regulation
CEO Dario Amodei has publicly called for binding government regulation of AI. He cited risks to cybersecurity, financial infrastructure, national security, and even biological systems.
Amodei compared AI to cars, planes, and drugs — useful but dangerous if poorly managed. He warned that more stringent oversight may be needed as AI systems become more powerful.
Anthropic is currently in discussions with the Trump administration following a government directive to disable access to its latest models, Fable 5 and Mythos 5.
The brokerage firms that will handle retail IPO allocations have not yet been announced.
