SAN FRANCISCO, November 10, 2026 — Anthropic is pushing ahead with a November initial public offering that Wall Street expects to value the AI startup between $1.5 trillion and $2 trillion. A debut at the top end would eclipse SpaceX for the largest IPO in history.
The Bottom Line
The figure that matters is the valuation gap: the company was worth $965 billion in a May Series H round, and bankers are now pitching a price up to double that. Investors will note the offering tests whether public markets will pay a premium for pure-play AI exposure while the broader tech sector wrestles with higher rates and volatile listings.
By the Numbers
Anthropic’s flagship Claude family spans four tiers — Fable, Opus, Sonnet and Haiku — plus the restricted Mythos line for vetted U.S. security and life-sciences organizations. The latest Fable 5.2 and Mythos 5.2 models, released Monday, run 30 percent faster than their predecessors. Fable 5.2 is priced at $8 per million input tokens, a 20 percent cut from the prior version and below the rate for rival GPT-6 Astra. On Anthropic’s agentic coding benchmark at “Xhigh effort,” Fable 5.2 scored 49.1 percent versus 32.4 percent for Fable 5.1. Mythos 5.2 lifted its cybersecurity score to 76.3 percent from 61.7 percent.
Founders and Structure
Former OpenAI executives Dario Amodei and Daniela Amodei founded Anthropic in January 2021 as a public-benefit corporation headquartered in San Francisco. Dario serves as CEO; Daniela is president. The company’s charter mandates a focus on AI safety, a stance that has shaped product decisions and, at times, limited government contracts.
Backers: Amazon and Google
Amazon has invested $18 billion to date and holds a financing agreement for up to $15 billion more. As of September 30, its non-voting preferred stake was valued at $92.5 billion, and it carries $146.2 billion in notes convertible to stock at the IPO. Google owns more than 5 percent of outstanding shares after billions in prior investment and disclosed plans in April to commit up to $40 billion more contingent on performance milestones.
Both cloud giants are also major compute suppliers. Anthropic has agreed to spend more than $100 billion on Amazon Web Services over ten years and entered a reported $200 billion, five-year deal for Google Tensor Processing Units. Those arrangements generate revenue for the backers even as their own AI labs — Google DeepMind and Amazon’s internal efforts — compete directly with Anthropic’s models.
Market Backdrop
The listing arrives amid turbulence in tech equities. Higher interest rates have compressed multiples, and recent AI-related debuts have swung wildly post-pricing. If Anthropic prices near $2 trillion, it would surpass SpaceX’s record and become the most valuable pure-play AI company on public markets, ahead of OpenAI’s private valuation.
Risks and What Comes Next
Analysts warn that missing lofty profit expectations could trigger massive write-downs for Amazon, Google and other early holders. Dorothy Lund, co-director of Columbia Law School’s Ira M. Millstein Center for Global Markets and Corporate Ownership, told Yahoo Finance: “There’s risk to their investment in that … who knows in five years whether Anthropic will be the most profitable company in the world — or worth nothing.” The IPO is scheduled for later this month.
