Anthropic IPO Is 'Multiple Times Oversubscribed' as Roadshow Begins

Anthropic's initial public offering roadshow launched Tuesday and demand is already through the roof. The Claude chatbot maker has drawn orders for multiple times the stock on offer, Bloomberg reported Wednesday, driven by large anchor‑style expressions of interest from institutional investors.

Through the IPO and a concurrent private placement, Anthropic and its co‑founders could raise as much as $90.4 billion combined at the top of the price range, according to Quartz. That would surpass SpaceX's IPO earlier this year and set a new record for a stock market debut.

Anthropic is selling 825 million Class A shares priced between $70 and $78 per share, according to Reuters. At the top of that range, the company would be valued at roughly $1.4 trillion on a fully diluted basis, which includes stock options and restricted stock. On a non‑diluted basis the market value would be about $1 trillion.

The stock is expected to begin trading on the Nasdaq Global Select Market on November 19 under the ticker ANT. Goldman Sachs and Morgan Stanley are leading the offering alongside more than 20 additional banks.

Anthropic also arranged a separate $26 billion private placement with cornerstone investors including Google, Nvidia, AMD, Broadcom, Micron, Microsoft, and TSMC — a who's‑who of the AI hardware and cloud ecosystem.

The $1.4 trillion figure is a significant step down from where expectations sat just weeks ago. The valuation has swung wildly: investors were discussing close to $2 trillion as recently as six weeks ago, then expectations settled around $1.5 trillion before large backers pressed for a lower number after an AI stock selloff last Thursday, Reuters reported. In a note to viewers, Reuters described the swing as "a wild swing in valuation" that reflects broader uncertainty about how to price AI companies, adding that with the VIX fear index above 20, it's a more volatile moment to go public.

Still, Anthropic's last private round — its Series H in May 2026 — valued the company at $965 billion. Even at $1.4 trillion, that represents a roughly 45% premium in six months. And with the IPO now oversubscribed, the Financial Times reports that bankers are already preparing to increase the valuation to $1.5 trillion.

Anthropic's run‑rate revenue hit $81 billion as of October 31, according to Reuters. The company is promoting the offering through investor events including a live‑streamed session Friday with CEO Dario Amodei and JPMorgan Chase CEO Jamie Dimon.

The financial metrics land alongside a traffic surge. Claude recorded roughly 1.3 billion web visits worldwide in October, a 23.8% jump from September's 1 billion and Claude's biggest month ever, according to Similarweb data shared with.³ Year‑over‑year, Claude traffic is up 536.3% — far exceeding any other top AI chatbot.

Claude remains third in web traffic behind ChatGPT (6 billion visits) and Gemini (2.6 billion), but jumped six spots to No. 25 on Similarweb's most‑visited websites list. Meanwhile ChatGPT recovered to 6 billion visits — its best month in a year — and Gemini held steady at 2.6 billion.

Anthropic's IPO is the first major test of public‑market appetite for frontier AI companies. Rival OpenAI confidentially filed for an IPO earlier this year but has since said it won't launch in 2026, according to Forbes. That gives Anthropic a clear runway as the first major AI lab to hit public markets.

On the financial side, Anthropic draws a higher percentage of its revenue from enterprise customers compared to OpenAI, ProShares noted in a comparison analysis. OpenAI is currently raising a pre‑IPO round at roughly $1.2 trillion and topped $10 billion in quarterly revenue, though operating losses remain high.

Morningstar analysts, meanwhile, told investors they see Anthropic stock as undervalued in the current IPO pricing range — a bullish signal amid the broader AI stock turbulence.

For developers who build on Claude, Anthropic's public listing matters in concrete ways. A well‑funded Anthropic with public‑market discipline means continued investment in the Claude API, Claude Code, and the broader developer ecosystem. The $26 billion private placement from chipmakers and cloud providers signals that the hardware supply chain is deeply committed — builders won't face compute shortages driven by Anthropic's own infrastructure gaps.

The oversubscription also validates Anthropic's safety‑forward positioning. While some investors were spooked by the AI stock selloff, the incoming demand suggests the market believes Anthropic's enterprise‑heavy revenue mix and measured approach to deployment are real competitive advantages, not just PR.

The roadshow continues through next week with the pricing expected around November 18 and trading to begin November 19 on Nasdaq under ANT.
