Anthropic IPO Delayed to Mid-October, Eyes $2 Trillion Valuation

Anthropic has postponed the timeline for its highly anticipated initial public offering, with the artificial intelligence company now expected to file its prospectus in late September and begin marketing the offering no earlier than mid-October, according to people familiar with the matter cited by Reuters.

The delay pushes back what was expected to be one of the most closely watched technology IPOs in years. The company had originally planned to make its prospectus public as early as next week, but that schedule has slipped as Anthropic works through regulatory reviews and financing arrangements.

Financing and Preparation

A key factor in the revised timeline is Anthropic's effort to finalize a $15 billion revolving credit facility. Once that financing is secured, analysts from the banks underwriting the IPO are expected to meet with the company before the prospectus becomes public. The banks working on the offering include Morgan Stanley, Goldman Sachs, JPMorgan, and Citi, according to people familiar with the process.

The compressed timeline between analyst meetings and the public filing is unusual, though sources note the banks already have substantial familiarity with Anthropic's business.

$2 Trillion Valuation in Play

Investors have discussed a potential valuation of up to $2 trillion for Anthropic, which would rank the offering among the largest IPOs ever attempted. That figure would make the listing an unusually consequential test of public market appetite for artificial intelligence investments.

If the current schedule holds, Anthropic could complete its listing just days before the U.S. midterm elections in November, though the timing remains subject to change.

Why it matters

Anthropicā€™s IPO will serve as a critical barometer for whether public markets are prepared to absorb massive AI valuations at a time when investors are increasingly focused on distinguishing between companies that can translate AI spending into sustainable returns. The offering could provide one of the clearest opportunities for public-market investors to directly value a company at the center of the AI investment boom, potentially alongside other major AI listings including OpenAI.

Market Context

The delay is not necessarily a signal of deteriorating market conditions or abandoned plans. Companies routinely adjust IPO schedules as they navigate regulatory processes and prepare for investor roadshows. However, the revised timetable does push a major test of AI market sentiment further into autumn.

The market has already demonstrated willingness to assign extraordinary valuations to AI-adjacent companies. SpaceX went public in June at a record $1.77 trillion valuation, setting a precedent for the scale of public offerings in the current technology cycle.

Anthropicā€™s eventual listing will arrive at a moment when the gap between AI investment commitments and proven business models remains a central question for investors. The companyā€™s reception in public markets could influence the trajectory of other AI companies considering similar moves.

These details were first reported by Reuters. Both Anthropic and the banks involved declined to comment on the timeline or financing arrangements.
