Anthropic’s confidential S-1 filing and reported $2 trillion IPO target continue to anchor trader expectations for a high closing market cap, driven by annualized revenue run rates exceeding $65 billion and projections approaching $110–120 billion by year-end. The company’s May 2026 Series H round at a $965 billion valuation, followed by Nasdaq Private Market marks near $1.39 trillion, reflects sustained investor appetite for its Claude large language models amid hyperscaler partnerships and infrastructure commitments totaling $518 billion. Delays shifting the listing from October into November after U.S. midterms introduce timing uncertainty, while analyst skepticism over sustained profitability and valuation multiples near 18–30x sales highlights risks of a lower debut. Q3 results and any anchor investor commitments will serve as key near-term catalysts.
