Anthropic IPO roadshow sets $70-$78 range, up to $1.4T valuation, with ANT trading Nov 19

Anthropic has formally begun marketing its IPO. The price range is $70 to $78 a share, and the top end implies a market value of roughly $1.4 trillion. The company is targeting $62.5B in primary proceeds plus a $26B private placement running alongside the offering. CNBC, citing sources, puts pricing on November 18 and the first trade on November 19 under the ticker ANT. On November 12 Anthropic's official X account posted its IPO page with the required SEC prospectus disclaimer (9.4K likes). The ipo.anthropic.com page became the day's top Hacker News thread at 838 points and 815 comments.

The cornerstone list stands out because it reads like a map of the AI supply chain. Google, NVIDIA, Microsoft, AMD, Broadcom, Micron and TSMC are all named. Cloud, chip, memory and foundry partners are each taking equity alongside public investors. That aligns Anthropic's suppliers with its success, but it also deepens the web of circular AI investment that analysts have been debating. Per the prospectus figures reported by Reuters, nine-month 2026 revenue reached $33.2B, up 1,206% year over year.

In competitive terms, this would be the largest tech IPO on record and the first frontier lab to list. Its timing relative to OpenAI's own capital plans will shape how public markets value labs that remain loss-making at scale. The roadshow also coincided with new Claude office products, which suggests Anthropic wants to pitch enterprise breadth, not just model leadership.

The main risk is market sentiment. NVIDIA's CEO resignation the same week injects volatility into the AI complex, and NVIDIA is itself a cornerstone investor. Community threads frame the November 19 debut as a referendum on AI startup economics, with optimism that remains measured. Watch whether pricing lands above or below range, how much the cornerstones absorb, and the disclosed burn and compute commitments.
