Reports say Anthropic’s formal marketing could begin the week of November 9, with a scale that could match or exceed SpaceX
According to reports from The Information and IFR, Anthropic could publicly file its S-1 registration statement for its IPO as early as Monday, October 26, Eastern Time. IFR had previously reported that the company planned to publicly file on October 26 and begin its roadshow the week of November 9, with pricing possibly in the following week, aiming to raise up to $100 billion at a valuation of up to $2 trillion. Morgan Stanley and Goldman Sachs are reportedly serving as joint lead underwriters.
Anthropic submitted a confidential draft S-1 to the U.S. Securities and Exchange Commission (SEC) on June 1, 2026. Under SEC rules, companies using the confidential filing process must publicly release their registration statements at least 15 calendar days before the formal roadshow begins. Bloomberg previously reported that the company was seeking to go public as early as mid-November, with formal marketing possibly starting the week of November 9 so that trading could begin before Thanksgiving (November 26). People familiar with the matter expect its IPO to be on a scale comparable to or even larger than SpaceX; when SpaceX went public in June, its valuation was about $1.75 trillion to $1.77 trillion.
As of this report, the SEC EDGAR system had not yet shown Anthropic’s public registration statement. The company did not immediately respond to questions about the timetable. The timing of the IPO still depends on market conditions and other factors.

ABAB AI Insight
An Anthropic public S-1 filing would give the market its first systematic look at the company’s financials, compute commitments, and risk factors. The company has already filed confidentially, and parts of the draft disclosed by media reportedly showed about $4.6 billion in 2025 revenue, about $42 billion in net losses (including accounting adjustments tied to large financing rounds), and plans to spend about $518 billion over time on cloud computing and infrastructure. The public filing will further clarify customer concentration, the structure of long-term compute contracts, and governance arrangements.
On the capital-markets side, this IPO is seen as one of the largest public-market tests in AI, with a target size that could match or exceed SpaceX. The company must satisfy the 15-day public disclosure requirement before the roadshow, and the timetable is affected by the Thanksgiving holiday and market volatility. Underwriters and valuation targets have appeared in reports, but the final offering size, pricing, and listing date still depend on demand and market conditions. Amazon and Google, which are both investors and compute suppliers as well as competitors, have quarterly earnings close to Anthropic’s filing window, which could affect market views on AI spending and returns.
Compared with other large IPOs such as SpaceX, Anthropic’s public filing will more fully reveal the loss structure and infrastructure commitments of a model company. Previously leaked information indicated that the risk factors section was lengthy and covered technical and operational uncertainties. Investors will focus on the sustainability of revenue growth, control of compute costs, and contract arrangements with hyperscale cloud providers.
If the filing is submitted on the reported schedule, the market will gain verifiable financial and risk disclosures to assess its scale and pricing relative to SpaceX. The actual roadshow launch and pricing may still be adjusted because of market conditions, and the public filing itself does not mean a confirmed listing date or final valuation.

After a confidential filing, a public S-1 submission must satisfy the requirement to disclose at least 15 days before the roadshow, making the schedule subject to regulatory procedure.
A large IPO by an AI model company simultaneously tests the market’s ability to price high-speed revenue growth and large-scale compute spending commitments.
Cloud providers that are both investors and compute suppliers will have their business relationships and competitive positions examined more systematically in the public filing.
