Anthropic’s recent S-1 filing on October 26 has anchored trader sentiment around a $100B-plus IPO raise, with the two leading market outcomes clustered at $105–125B. Explosive revenue growth to $16.3 billion in the first half of 2026, driven by enterprise adoption of its Claude large language models, supports aggressive valuation targets between $1.5T and $2T, while hyperscaler partnerships with Amazon and Google supply both capital and compute. Steep net losses exceeding $80 billion in the period—largely non-cash accounting charges—alongside over $500 billion in future infrastructure commitments highlight execution risks in a competitive AI landscape featuring OpenAI and Chinese models. The Nasdaq listing under ticker ANT is slated for November, making the final share count and pricing the key near-term catalysts.
