Anthropic’s recent S-1 filing on October 26, 2026, serves as the main catalyst anchoring trader consensus around the $1.50–$1.75 trillion range. The prospectus highlighted Claude’s rapid revenue expansion to $16.3 billion in the first half of 2026 alongside substantial operating losses and multi-hundred-billion-dollar compute commitments, prompting investors to moderate earlier $2 trillion expectations. This data, paired with Anthropic’s positioning in the competitive large language model landscape against OpenAI and Google, has shaped current market-implied odds. The upcoming roadshow the week of November 9 and targeted mid-November Nasdaq listing under ticker ANT remain key near-term events that could refine final pricing within or slightly outside the leading band.
