Anthropic's November IPO timing faces doubt after AI stock rout
Reuters reported on November 5 that potential investors doubt Anthropic can complete its roadshow in time for a November listing. The roadshow was expected to start the week of November 9, with pricing the following week. Some investors see the roughly $1.5 trillion valuation under discussion as the top of their range, and some expect a larger discount to secure orders. Earlier this year, the listing had been expected in October at up to $2 trillion, a figure that was reported but does not appear in the filing.
The doubts follow the sharpest tech selloff in a year. On November 5, chip stocks fell 12.3% and Nvidia dropped 9.2%, according to kingy.ai, which cites CNBC and NBC. Nvidia closed at $181.60, according to Motley Fool. Forbes tied the selling to fears that a Democratic Congress would slow data center construction after the midterm elections.
Anthropic's S-1, filed publicly on October 26, names Nasdaq and the ticker ANT, with Goldman Sachs and Morgan Stanley leading underwriting. It reports $16.3 billion in first-half 2026 revenue and a net loss of about $80.7 billion, and it leaves the share count and price range blank. Companies that filed a draft privately must wait at least 15 calendar days after the public filing before launching a roadshow, according to Yahoo Finance.
Why it matters
For founders and investors, the IPO price becomes a public reference point for private AI valuations. Anthropic's last private round, a $65 billion raise, valued the company at $965 billion, according to CoinMarketCap, so a $1.5 trillion listing would already imply a large step up. A delay would slow the late-stage market because private buyers lack a public price to anchor to. A lower price would reset expectations for other labs and their suppliers.
Operators planning raises should track three items: the amended filing with a price range, the October revenue figure, and the quarterly losses and compute commitments the filing discloses. Nvidia's November 17 quarterly update will also show whether chip demand holds, which affects the cost of compute for every model builder. If the public window stays shut, capital needs may shift toward private rounds with tougher terms.
