Anthropic starts pitching its record IPO to investors, with the price still unsettled

Anthropic began formally marketing its initial public offering to investors on Monday, Bloomberg reported. CNBC and The Information also said the roadshow, the series of meetings where bankers sell the shares to big investors, would go ahead this week. Last week, after the Nasdaq 100 fell 6.4% in a single day, some prospective buyers doubted the November listing would happen at all.

The decision matters well beyond Anthropic. The deal would be the largest IPO on record, ahead of SpaceX's June listing. It is also the first time public-market investors will put a price on a company that does nothing but build frontier AI. That price will feed back into how investors value AI chipmakers, cloud providers and the private AI startups that raise money off Anthropic's numbers.

Anthropic is seeking to raise $80 billion to $100 billion at a valuation of $1.25 trillion to $1.75 trillion, the Financial Times reported on November 6, citing people familiar with the plans. That is above its last private valuation of $965 billion. It is well below the roughly $2 trillion its most bullish backers discussed a month ago.

The gap between seller and buyers

Buyers are aiming lower than the top of Anthropic's range. Prospective investors have discussed $1.2 trillion to $1.3 trillion, and as low as $1.1 trillion, Bloomberg reported. One large investor told the FT it expects Anthropic to start conservatively, at around $1.5 trillion, and go up from there. Others in the deal expect closer to $1.3 trillion.

Mergermarket's ECM Pulse, which covers equity deals for ION Analytics, was blunter on Monday. Before the selloff, its own analysis pointed to a valuation of $1.2 trillion to $1.45 trillion. Its post-selloff model points to about $1 trillion, and its stress tests go lower. It described Anthropic's choice as listing well under its target or delaying, possibly for good.

Neither option is free. Pulling the deal could send another shock through an already nervous market, one investor told ECM Pulse. An adviser said pricing correctly was essential, "or it could be a disaster." Another adviser suggested Anthropic could cut both its valuation and the number of shares it sells, as OpenAI did when it scaled back its latest private round.

What buyers are weighing

The growth case is strong. Anthropic's amended filing shows third-quarter revenue of $17.0 billion. That was up nearly 50% from the second quarter, but growth slowed sharply from the quarter before. The FT put the company's annualized revenue pace at about $81 billion, a figure not in the prospectus.

The cost side is what makes buyers cautious, and it keeps growing, including a reported purchase of its own gas-fired power generators. The filing lists about $895.4 billion of purchase commitments and leases, substantially all for computing capacity and data centers. About $69.8 billion of that falls due in the 12 months after September 30. Anthropic held $131.8 billion in cash and short-term investments at that date. It reported an operating loss of $1.26 billion for the first nine months of 2026, on a standard accounting basis.

ECM Pulse flagged a less obvious risk. The commitments include take-or-pay terms, meaning Anthropic pays whether or not it uses the capacity. If voter opposition slows data center construction, computing prices could rise. Anthropic might then have to buy extra capacity at higher short-term prices, squeezing its margins.

Buyers will also weigh control. Under the filing, a class of shares held by Anthropic's seven co-founders will carry 50.1% of the total voting power. Public shareholders could not outvote the founders on most matters put to a shareholder vote.

The calendar from here

The next signal is a price range. Anthropic's November 2 amendment left the range and share count blank, and those details usually arrive in a new filing as marketing starts. Under SEC timing rules, Yahoo Finance calculated, the earliest realistic pricing date is Friday, November 13, with trading on Nasdaq under the ticker ANT as soon as November 16. Bloomberg has reported a target of listing before Thanksgiving on November 26.

The roadshow runs into a crowded week. CoreWeave, a cloud company that rents AI computing power, reports third-quarter results on Tuesday. It has guided to $860 million to $940 million in quarterly interest costs against $200 million to $260 million of adjusted operating income. That will show how much debt is weighing on companies that rent out AI computing capacity.

The record also argues for caution on day one. SpaceX priced at $135 a share in June and fell well below that in last week's selloff, ECM Pulse noted. Prediction-market traders on Kalshi still put the odds of an Anthropic IPO before December above 80%, Seeking Alpha reported.

For investors, three numbers will tell the story: the price range Anthropic files, whether it trims the $80 billion to $100 billion raise, and where the stock trades in its first week. A range that starts near $1.25 trillion would mean Anthropic has accepted the market's lower price. A range anchored near $1.75 trillion would mean it is betting demand can still be found at the top.
