Anthropic Kicks Off IPO Roadshow Next Week as Valuation Expectations Slide From $2 Trillion
Anthropic is pressing ahead with its stock market debut even as investors keep cutting what they are willing to pay for it. The company behind Claude is expected to start its IPO roadshow next week, with a listing targeted for the week of November 16, ahead of Thanksgiving. But the number at the centre of the deal has slid hard: prospective buyers are now discussing a valuation of $1.2 trillion to $1.3 trillion, with some as low as $1.1 trillion. That is down from roughly $2 trillion when Anthropic entered October.
Nothing is final yet. The price range is still blank in the filing, and some investors openly doubt the timetable will hold. So what has actually changed, and what should you watch next?
The roadshow plan
According to reports from The Information and CNBC, Anthropic will start its roadshow next week, meeting institutional investors to build the order book before pricing. The Financial Times reported the company is seeking to raise $80 billion to $100 billion at a valuation of roughly $1.25 trillion to $1.75 trillion, with a public-market debut targeted for the week of November 16.
The timing is tight. Anthropic made its IPO filing public on October 26, after filing confidentially in June, and has applied to list on the Nasdaq under the ticker ANT. The law requires the public filing to sit for at least 15 days before the roadshow, which puts the earliest lawful marketing start at November 10.
But the schedule is not locked in. Reuters reported that four people familiar with investor talks question whether the roadshow can start next week in time for a November listing, and The Wall Street Journal reported that executives and advisers are expected to meet in the coming days to review the deal. If the roadshow slips, the listing slips with it.
How far the valuation has fallen
The slide has been steep and fast. In early October, Bloomberg reported discussions of $1.8 trillion to $2 trillion. By mid-October, investors were using roughly $1.5 trillion. On November 6, Bloomberg reported prospective buyers were discussing $1.2 trillion to $1.3 trillion, with some as low as $1.1 trillion. The Wall Street Journal reported one investor suggested a level closer to $1 trillion.
Only one number in that sequence comes from a priced deal: the $965 billion post-money valuation from Anthropic’s $65 billion Series H round in May 2026. Everything since is reported investor discussion, not a filed term. Anthropic has declined to comment to Bloomberg, Reuters and CNBC.
For a sense of scale, this is still an enormous listing. Even at $1.2 trillion, it would rank among the largest IPOs ever. The point is not that Anthropic is in trouble — it is that the market’s appetite for AI stocks has cooled sharply in a matter of weeks.
What the filing actually says
Anthropic’s amended prospectus, filed on November 2, leaves the price range, the number of shares to be sold and the October run-rate revenue figure blank. The cover literally reads “will be between $ and $”. That is normal at this stage of an IPO, but it means no valuation has been set on the public record.
The filing did add fresh numbers for the September quarter: revenue of $17 billion, with growth halving to 47 percent, and a swing back to a $567 million operating loss. Those figures fed the caution. Growth is still fast by any normal standard, but it is slowing, and the company is spending heavily to keep up.
Readers who followed Anthropic’s S-1 filing in October will recognise the shape of this story: a company moving fast toward the public markets while the market itself is repricing the whole AI sector.
Why investors pulled back
The selloff did the damage. The Nasdaq Composite fell 5.5 percent on Thursday, November 5, putting the index in correction territory and almost 12 percent below its high of October 6. AI stocks led the drop, and Anthropic’s own numbers gave buyers a reason to hesitate rather than chase.
The same chill is showing up elsewhere. OpenAI’s $1.25 trillion funding round fell short of its original $1.4 trillion target, and Anthropic’s rival is dealing with the same repricing. When the biggest private AI companies both see their numbers cut in the same month, the story is about the market, not one company.
What to watch next
The next hard evidence will be a new amended filing. The October run-rate revenue figure, the price range and the share count will show where the final valuation actually lands. Until then, every number you see is a report, not a fact.
Three things to track: whether the roadshow actually starts next week, whether the price range lands near $1.2 trillion or closer to $1 trillion, and whether the listing still happens before Thanksgiving. If all three hold, Anthropic will have pulled off one of the biggest listings in history — just at a price nobody expected a month ago.
