Anthropic Targets $2 Trillion IPO Amid Safety and Market Headwinds

Anthropic is preparing a mid-November initial public offering that could value the AI firm between $1.8 trillion and $2 trillion. If realized, the listing would eclipse SpaceX’s 2023 offering and become the largest U.S. IPO on record. The company intends to begin marketing the offering during the week of Nov. 9 and hopes to have shares trading before Thanksgiving.

The announcement follows a year of heightened scrutiny of advanced-AI developers. In June 2026 Anthropic confidentially filed to go public, and in September its chief executive Dario Amodei appeared at the White House to sign a self-regulation accord with other tech leaders. At the same time, rising interest rates, the war in Iran and a “shakier economy ex-AI” have dampened investor sentiment, prompting firms such as Oura and Holtec Nuclear to postpone IPO plans. OpenAI also delayed its offering citing safety concerns.

Amodei has urged a slowdown in AI development, arguing that “self-policing” through the White House accord is essential. Jill E. Fisch, professor of business law at the University of Pennsylvania Carey Law School, cautioned that no firm can “cross the threshold” of safety with absolute confidence. Analysts note strong demand for Anthropic’s Claude models despite the massive cash burn, while others stress that execution of the business model remains the key determinant of success.

Anthropic plans to file a formal registration statement in the coming weeks and to commence a roadshow during the week of Nov. 9. The company must also navigate the FTC investigation and address the existential-risk warnings embedded in its prospectus before the shares can be listed. Market observers will watch whether investor appetite can absorb the firm’s unprecedented scale of spending and loss profile amid an uncertain macroeconomic backdrop.
