Anthropic Delays IPO Roadshow to Mid-October with $2 Trillion Valuation at Stake
Reuters reveals that Anthropic has postponed the start of its roadshow to mid-October while finalizing a $15 billion revolving credit facility, six times larger than its previous round.
Anthropic has delayed the kickoff of its IPO roadshow to mid-October, according to an exclusive report by Reuters published this Friday, September 5. The company had previously indicated that it would open the prospectus to the public shortly after the U.S. Labor Day holiday on September 7, with a listing planned for the end of the month. According to sources close to the process interviewed by Reuters, the marketing period for the shares has been pushed back by at least four weeks.
The public prospectus is expected to be filed in September. At the same time, Anthropic is finalizing a $15 billion revolving credit facility, six times larger than the $2.5 billion line secured in the previous round. Morgan Stanley, Goldman Sachs, JPMorgan, and Citi are coordinating the offering.
The Valuation That Will Define the AI Market
Some institutional investors project that the listing will value Anthropic at up to $2 trillion, positioning the offering above Aramco as the largest IPO in history. The company concluded its Series H-1 round in May 2026 with a valuation of $965 billion and has raised $130 billion in private rounds since its inception. The implied leap between the two valuations requires an explanation that the coordinating banks are still building for the roadshow.
Documents shared with potential investors point to an internal revenue projection of $190 billion to $200 billion for 2028. This figure is relevant less as a target than as a pricing methodology: the banks are evaluating a high-growth asset, not a mature business with established margins. The $15 billion credit line serves as working capital to cover heavy compute expenses while revenue grows, but Anthropic’s operational profitability has not been publicly disclosed.
The market has no direct precedent: no frontier AI lab has gone public before. The most cited parallel is Nvidia in 2023, when the market priced in years of growth before operational profits scaled. The structural difference is that Nvidia sold chips with revenue recognized in the quarter of delivery, whereas Anthropic sells inference capacity via API and subscription, with contracts whose recurring value lacks audited history in the public market.
Why October and Not September
The mid-October window is not accidental. This period is historically the most favorable of the year for large-cap IPOs: managers have finalized third-quarter earnings, are not yet in the sprint for year-end closings, and the volume of new competing offerings is typically low. The goal, according to Reuters sources, is to complete the operation before the American midterm elections in November.
The political risk is real. The Stop Rogue AI Act, a bipartisan bill introduced in Congress last week by Representatives Josh Gottheimer and Mike Lawler, establishes traceability obligations for autonomous agents that directly impact Anthropic's products aimed at agentic workflows. If the election results favor a more restrictive legislative composition, the shares could open their second week of trading under regulatory pricing pressure.
Insights for Markets Outside the United States
For European funds exposed to foundational generative AI, Anthropic's debut pricing will serve as a multiple anchor. Managers holding positions in Mistral or emerging AI companies in the UK and Germany will use the opening value to reassess internal portfolio valuations as they close the third quarter.
In India, TCS, Infosys, and Wipro have reported revenue growth stemming from AI implementation contracts anchored in Anthropic's APIs. A publicly traded technology partner with quarterly disclosure obligations has a different profile for corporate procurement contracts than a private lab: regulated clients, from banks to insurance companies, demand contractual continuity that a public company has more difficulty denying.
The four-week delay also allows time to include in the prospectus the company’s response to the EU AI Act, which has been in effect since August 2026. Anthropic has yet to publicly announce its formal compliance strategy for the European market, and this gap is likely to appear as a risk factor in the final version of the S-1.
