The claim
The Anthropic S-1 IPO filing is publicly submitted to the SEC before November 14, 2026, with a stated valuation range implying a market cap of at least $1.5 trillion.
Reasoning trace
- Anthropic pre-IPO markets price above $2T, creating strong incentive to file before year-end to capture valuation
- Clarity Act Senate collapse removes crypto as competing capital destination, increasing AI IPO appetite
- Fed rate hike creates urgency to file before further tightening narrows IPO window
- S-1 submitted to SEC with valuation range anchored at $1.5-2T, triggering roadshow preparation
