Anthropic IPO: $1.4T Valuation, $70-78 a Share

Anthropic, the company behind Claude, has put a price on itself. On November 10, 2026, it launched its IPO roadshow with a proposed price range of $70 to $78 per Class A share for 825 million shares. At the top of the range, the offering would raise about $64.35 billion before fees, and value the company at up to $1.4 trillion on a fully diluted basis. That would make it one of the largest IPOs in stock market history, and the first time a frontier AI lab lists on a public exchange.

The shares are expected to trade on the Nasdaq Global Select Market under the ticker ANT. Reports point to final pricing on November 18 and a first trade on November 19, though the European prospectus schedules pricing for November 19 and trading for November 20, so treat the dates as expected, not final.

The deal at a glance

Why two valuations, $1 trillion and $1.4 trillion

Both numbers are correct, they just count different shares. The roughly $1 trillion figure uses shares outstanding after the offering. The roughly $1.4 trillion figure is fully diluted, counting options, restricted shares and other rights to future equity. Reuters reported both, and the Financial Times reported that bankers are weighing a price above the filed range, which could push the target to $1.5 trillion or more.

For context, Anthropic's last private round in May 2026 valued the company at $965 billion. The midpoint of the IPO range, $74, implies about $968 billion on basic shares, almost exactly the May mark. The IPO is not a step up on that measure. The step up appears only on the fully diluted count.

The $26 billion private placement

Alongside the public sale, Anthropic plans a $26 billion private placement of Class N shares, subject to the IPO closing. Google and Nvidia account for $10 billion each, with AMD, Broadcom, Micron, Microsoft and TSMC Partners rounding out the group. At the $74 midpoint, Anthropic estimates about $84.6 billion in net proceeds from its part of the public sale plus the placement, assuming the banks do not exercise their option to buy up to 123.75 million additional shares.

The financials behind the price

The prospectus shows a business growing fast and spending faster. Revenue rose 47% from the second to the third quarter of 2026, from $11.56 billion to $16.96 billion. Compute and infrastructure expenses rose 77% over the same period, from $5.56 billion to $9.86 billion. That swing turned a $974 million operating profit in Q2 into a $567 million operating loss in Q3.

For the nine months through September, Anthropic reported $33.24 billion in revenue and $18.81 billion in compute and infrastructure expenses. The GAAP operating loss was $1.26 billion, while management reported $4.08 billion in adjusted operating income, a 12% margin, a company-defined measure that excludes items such as stock-based compensation.

The headline net loss looks far worse than the operating picture: $104.04 billion for the nine months, driven by a $94.32 billion fair-value adjustment on convertible notes, derivative liabilities and SAFEs. That is a non-cash remeasurement, not money paid out. Operating cash flow was $6.57 billion positive over the same period.

Two more numbers matter for anyone building on Claude. Annualized run-rate revenue was about $81 billion as of October 31, up from $71 billion a month earlier. And Anthropic held $131.85 billion in cash and short-term investments as of September 30, against $900.9 billion in purchase and lease commitments, mostly compute, running through 2045. About $451.6 billion of that falls due through 2030. The filing warns that some providers depend on third-party financing to deliver capacity, so contracted capacity can arrive late or cost more if financing tightens.

What this means for Claude users

An IPO does not change Claude's price or limits on day one. What it changes is the scrutiny. Anthropic will now report quarterly, and every quarter will ask the same question the prospectus already raises: can revenue keep growing faster than compute costs? In Q3 it did not.

Three things to watch after listing:

• Capacity and availability. The $900.9 billion in commitments is meant to buy years of compute in advance. Watch whether that turns into stable availability across regions and providers, or into usage limits when demand spikes.
• API pricing. Claude is sold directly and through cloud marketplaces, which accounted for 44% of revenue in the first nine months of 2026. If compute costs keep rising faster than revenue, pricing pressure follows.
• Governance. Anthropic is a public benefit corporation. Through Class T stock, the Long-Term Benefit Trust can generally elect and remove a majority of directors, and a single Class F share held by the co-founders' entity carries 50.1% of the voting power on specified general matters. Public shareholders will own the economics, not the control.

The bigger picture

Anthropic is the first frontier lab to test public markets at this scale. Its flagship, Claude Fable 5.2, currently tops the Artificial Analysis Intelligence Index at 65, ahead of Gemini 4 Carbon at 60. That ranking is part of the pitch: the best model, the fastest-growing revenue, and the biggest compute bill in the industry, all in one filing.

Investors will decide on November 18 whether $70 to $78 is the right price. For the rest of the AI industry, the verdict matters more than the number. If Anthropic lists near $1.4 trillion fully diluted, every other lab's valuation moves with it. If it prices below the range, the market has just put a ceiling on the AI boom.
