Analysis
Update, November 4, 2026
The October date in this August report did not hold. Anthropic filed its public S-1 on October 26, 2026 (SEC EDGAR), applying to list on Nasdaq as "ANT," and filed an amended S-1 on November 2 (SEC EDGAR) that adds third-quarter results: $17.0 billion of Q3 revenue and a $567 million GAAP operating loss. The amendment still leaves the price range and share count blank. As of November 4, the roadshow could begin as soon as November 10, with pricing no earlier than November 13 and trading potentially November 16-18, per Yahoo Finance. On valuation, investors are pushing for the low end of a $1.5 trillion to $2 trillion range, Fortune reported on November 3. For the full timeline, see our Anthropic IPO date tracker. The original August 13 report follows.
The Report
Anthropic is preparing for a stock market listing that could value the company at roughly $2 trillion, with a launch that could come as soon as October, according to the Financial Times as first aggregated by Fortune and corroborated by TipRanks. Morgan Stanley, Goldman Sachs and JPMorgan are the banks reportedly leading the offering. A $2 trillion valuation would be roughly double Anthropic's last private mark of $965 billion, set only months ago, and would make it the largest initial public offering in history -- eclipsing the roughly $1.77 trillion valuation at which SpaceX priced its June IPO.
Where the Number Comes From
The $2 trillion figure is coming from investors and bankers circling the deal, not from Anthropic's own public guidance -- senior executives have not confirmed an IPO valuation target even in private conversations, per the FT's reporting. The underlying revenue case: Anthropic reported more than $47 billion in annualized revenue in May, and investors are now pricing in that figure reaching $100 billion to $120 billion by December, driven by enterprise Claude adoption, API usage from coding tools, and the multibillion-dollar compute-supply contracts the company has signed with Microsoft, Nvidia and others this year.

Company Background
Anthropic was founded in 2021 by Dario and Daniela Amodei, former OpenAI executives, and has built its business primarily around the Claude family of models, sold through the Claude Platform API, claude.ai, and enterprise products including Claude Code and Claude Cowork. The company has raised successive private rounds through 2025 and 2026 from Google, Amazon, and a mix of sovereign wealth and venture investors, climbing from a roughly $60 billion valuation in early 2025 to $965 billion by mid-2026 -- one of the fastest private valuation trajectories any technology company has posted.
The Competitive Field
Anthropic's IPO would land in a market already anticipating OpenAI's own targeted listing, which in August was reportedly being discussed for as soon as September, and follows SpaceX's June listing. A $2 trillion Anthropic listing would put the company's implied value ahead of most S&P 500 constituents on day one, alongside Nvidia, Apple and Microsoft, despite Anthropic being a five-year-old company with a fraction of those firms' headcount and physical infrastructure. Google's own DeepMind unit, by contrast, has spent recent weeks contending with a leadership shake-up and talent departures rather than a public-listing narrative -- a reminder that Anthropic's IPO story is unfolding against real turbulence elsewhere in the frontier-lab field.
Numbers in Context
A jump from $965 billion to $2 trillion in a matter of months implies investors are pricing Anthropic's revenue not just continuing to grow but roughly doubling or tripling by December from its May run rate -- a projection that, if it holds, would put Anthropic's revenue multiple in a similar range to where it traded privately, rather than requiring a discount typical of newly public companies. That's a materially more aggressive assumption than the revenue growth OpenAI or most enterprise software companies have sustained at comparable scale.
The Counterweight
None of this was confirmed at the time. As of this August report, Anthropic had not filed public paperwork, has not set a valuation target internally by the FT's own account, and an October date is a reported target rather than a locked commitment -- IPO timelines for companies at this scale routinely slip by months. The projected $100 billion-to-$120 billion December revenue figure is also an investor forecast, not a disclosed Anthropic number, and compute costs at Anthropic's scale are enormous; a $2 trillion valuation prices in sustained revenue growth without addressing what the company's actual profitability looks like once its infrastructure commitments -- including deals with Microsoft, Nvidia and Riot Platforms -- are fully reflected in its cost base.
Public-market investors buying into a $2 trillion AI-lab valuation are also making a bet that Anthropic holds its position against OpenAI and Google in a field where the model leaderboard has changed hands more than once in the past two years.
Ahead
Anthropic has since filed (see the November 4 update at the top). The price range, still blank in the November 2 amendment, will show how much of the $2 trillion figure was investor anticipation versus a number the company and its banks are willing to defend to public shareholders.
