# Investors doubt Anthropic's IPO can reach $1.5T after the AI selloff

Full title: Investors doubt Anthropic's IPO can reach $1.5T after the AI selloff; one says ~$1T is closer (WSJ)

After the Nov 5, 2026 tech rout, the WSJ reported that major investors are increasingly sceptical Anthropic's planned IPO can achieve a $1.5T valuation, one saying it could be closer to $1T; Reuters said AI backlash could threaten the IPO's timing.

## Key facts
- Nov 7 (Yahoo Finance/Benzinga): one investor said Anthropic could postpone its IPO as the market sours on the AI trade, another that it could price closer to $1T than $1.5T; Bloomberg-sourced reports the same week said Anthropic still plans to list before Thanksgiving
- Nov 6 (Bloomberg via SiliconANGLE/Techmeme): Anthropic is continuing with plans to list before Thanksgiving, starting the process the following week; hopes for ~$1.5T, some investors suggest ~$1T
- FT (Nov 6, paywalled; read via Dealroom and other summaries): Anthropic is pressing ahead with a listing before Thanksgiving (Nov 26), aiming to raise $80B-$100B at a valuation of $1.25T-$1.75T, above its last private $965B but below the ~$2T hoped for in early October
- Bloomberg (Nov 6): prospective IPO buyers see a valuation as low as $1.1T after the post-midterm AI selloff (HN 283 points); TechCrunch, citing Bloomberg, gives $1.2T-$1.3T
- Ramp AI Index (TechCrunch, Nov 6): token spend grew only 1.5% across August-September after +42% June-July, then +8.9% Sept 23-Oct 23; Anthropic's filing says its price cuts on Fable 5.1 and Opus 5.5 reduced revenue growth by about $600M
- WSJ (Nov 5): investors sceptical of $1.5T; one suggests ~$1T
- Reuters (Nov 5): potential investors say AI backlash could threaten IPO timing
- Telegraph (Nov 6): 'Anthropic IPO in turmoil as AI sell-off hammers valuation'
- Written from headlines and summaries (WSJ paywalled)
