Anthropic IPO Valuation Falls to $1.5 Trillion as Investors Push Back

The most anticipated stock market debut of the year has turned into a negotiation. A month ago, the number attached to Anthropic's initial public offering was roughly $2 trillion. Now the investors who would actually have to buy the shares are telling Anthropic and its bankers that something closer to $1.5 trillion is fair — and some are going lower still. The roadshow is due to start next week, and the price of the AI boom is being haggled over in public.

The slide has been fast. The Wall Street Journal reported on November 2–3 that institutional buyers were guiding Anthropic toward a $1.5 trillion to $1.6 trillion valuation, down from the $2 trillion figure that circulated through October. Then came a sharp sell-off in technology stocks, and by November 6 the mood had hardened further: one investor called $1.5 trillion a stretch after the Nasdaq rout of November 5, and another put the likely range at $1 trillion to $1.25 trillion. The offering itself may shrink too, from around $100 billion to roughly $80 billion. Anthropic has not confirmed any target, and its amended prospectus still leaves the price range and share count blank — which is normal this far from pricing, but also means every figure in circulation is an estimate from people who want to buy cheap.

The pushback is not only about the market mood. Anthropic's own filing gives buyers room to argue. Third-quarter revenue reached about $17 billion, up 47% from $11.6 billion in the second quarter — real growth, and fast. But the quarter swung to a $567 million operating loss, driven by costlier short-term compute purchases, and the filing discloses roughly $895 billion in purchase commitments and leases for computing power, chips and infrastructure, with close to $450 billion due before the end of 2030. Michael Burry, the investor famous for betting against the housing market before 2008, has publicly expressed reservations about participating. The question buyers are asking is simple: does revenue growth this fast justify spending commitments this large? The honest answer is that nobody knows yet, and that uncertainty is exactly what the valuation fight is pricing.

What makes this more than one company's haggling is the timing. Anthropic plans to list Class A shares on the Nasdaq under the ticker ANT, with Goldman Sachs and Morgan Stanley leading 22 underwriters, and trading could begin as early as the week of November 16, before Thanksgiving. If the November window closes, the company still expects to go public before the end of the year. The listing is the largest test yet of whether public markets will pay private-market prices for frontier AI — and the early answer from the buyers is: not quite. A discount at the biggest AI IPO of the year would not be a verdict on the technology. It would be a verdict on the price, and on how much of the future investors are willing to pay for in advance.

My own judgement sits close to the middle of this argument. The $1.5 trillion line is the market's own compromise figure, and the forces pulling on it are evenly matched: on one side, the investor pushback, the cooling sequential growth and the sheer size of the compute bill; on the other, $17 billion of quarterly revenue growing at nearly 50% a quarter and a listing window that Anthropic is clearly determined to use. I put the chance that Anthropic prices at $1.5 trillion or less by the end of the year at about even — a coin flip, and deliberately so. The number that matters is the price at which funds actually sign their orders, and that only shows up when the roadshow opens next week.
