Anthropic’s recent S-1 filing on October 26, 2026, and the company’s trajectory toward a Nasdaq listing under ticker ANT in November underpin the 97.4% implied probability for a closing market cap above $600 billion. Revenue surged to $16.3 billion in the first half of 2026 from $1.2 billion a year earlier, while the May 2026 private round already priced the firm at $965 billion with investor targets now centered on $1.5–2 trillion. Trader consensus reflects this momentum and the scale of hyperscaler backing, though final pricing could shift if broader market conditions deteriorate or if disclosed risks around compute costs and AI safety prompt more conservative valuation multiples.
