• Anthropic publicly filed for its IPO on October 26, with trading potentially beginning before Thanksgiving, though the offering size and valuation remain fluid.
  • Market chatter points to a $100 billion raise at a $2 trillion valuation, but some investors are said to favor a more modest $1.5 trillion, according to Reuters (TRI).
  • A successful debut would test investor appetite for AI at scale and could set the tone for other AI listings, including a potential OpenAI IPO next year.

Filing Puts AI Giant on Cusp of Historic Debut

Anthropic took a major step toward becoming a public company on Monday, publishing its long-awaited registration statement with the U.S. Securities and Exchange Commission. The filing, which follows a confidential submission in June, sets the stage for what could be the largest IPO in history—if market conditions hold and investors embrace a trillion-dollar-plus valuation.

According to people familiar with the matter, the San Francisco-based AI developer aims to begin its investor roadshow in the week of November 9 and start trading before Thanksgiving on November 26. The company has not disclosed the size of the offering or a price range, but speculation has centered on a $100 billion raise at a $2 trillion valuation. That would surpass SpaceX (SPCX)’s record $86 billion IPO proceeds, including underwriters’ overallotment.

However, the final numbers remain in flux. Reuters reported earlier this month that some investors, after reviewing slowing quarter-over-quarter revenue growth and hefty infrastructure commitments, were considering a valuation closer to $1.5 trillion. Neither figure represents a final offer price.

Valuation Debate Takes Center Stage

The central question is whether exceptional demand for Anthropic’s Claude models can justify a trillion-dollar price tag while supporting the massive costs of supplying that demand. The company’s recent financials show both the promise and the pressure.

In the first half of 2026, Anthropic generated $16.3 billion in revenue, nearly fifteen times the $1.1 billion it posted a year earlier, according to reporting on the draft prospectus. But the company also recorded a net loss of $80.7 billion for the period, largely due to approximately $72 billion in financing-related accounting charges. Third-quarter revenue reached $16.8 billion, up 45% from the second quarter, and the company was reportedly profitable on an adjusted basis—though that does not equate to GAAP net profitability.

Meanwhile, infrastructure obligations loom large. Reuters reported at least $518 billion in commitments over a decade, while later draft-prospectus reporting put signed commitments around $600 billion, with another $150 billion under negotiation. Those are multiyear obligations, not current-year expenditures, but they underscore the capital intensity of the AI business.

“What institutional investors like us are really focused on is regulatory stability,” said one person familiar with the company’s thinking. “But at the end of the day, the valuation has to make sense.”

A Bellwether for AI

The IPO is being closely watched as a barometer for the entire AI ecosystem. A strong debut could validate the enormous investments being made by chipmakers, cloud providers, and data-center developers. A disappointing one could tighten financing conditions across the sector.

Anthropic’s backers include Amazon (AMZN) and Google (GOOG), which are also computing suppliers and competitors. Their overlapping roles create both advantages and dependencies. The company’s Claude Code programming tool has gained traction, and recent product announcements have emphasized faster models and lower operating costs.

Governance developments are also in focus. Physicist Christopher Stubbs joined Anthropic’s Long-Term Benefit Trust on October 21, and the company announced a Public Benefit Fund that will receive a portion of its shares. Those moves are aimed at addressing concerns about the societal impact of AI.

Regulatory Hurdles and Market Conditions

Anthropic’s path to listing is not without obstacles. The company’s June announcement explicitly said the IPO depends on SEC review, market conditions, and other factors. A confidential submission, a public registration statement, final pricing, and the first day of trading are separate milestones—and the headline should not collapse them into one completed event.

Regulatory risk is also real. Earlier this year, Commerce Department export restrictions led Anthropic to disable access to some of its models, though those controls were later lifted. The company has been expanding government relationships abroad, including a recent agreement with Singapore’s government on responsible AI adoption.

As of Monday morning, Anthropic had not set a price range for the offering. A spokesperson declined to comment beyond the filing.

Correction: An earlier version of this article misstated the timing of Anthropic’s confidential submission. It was filed on June 1, not June 30.
