Anthropic’s pending Nasdaq IPO, with shares marketed at $70–$78 and a fully diluted valuation range of $1.26–1.40 trillion, is the dominant factor anchoring trader sentiment ahead of the November 19 debut. The November 10 pricing disclosure moderated earlier $2 trillion expectations after an AI-equity sell-off, elevated data-center commitments, and questions over sustainable margins, even as run-rate revenue reached $81 billion by late October and quarterly revenue scaled rapidly from prior periods. A concurrent $26 billion private placement with strategic investors including Google, Nvidia, and AMD provides additional support at the IPO level. With resolution only days away, market-implied odds cluster in the $1.25–1.50 trillion band, reflecting the narrow window for any final pricing adjustment or post-listing volatility to shift the end-of-month outcome.
