Anthropic’s recent S-1 filing and explosive revenue trajectory—Q3 2026 sales reaching $17 billion after a 1,368% year-over-year surge—anchor Polymarket trader consensus on a $1.25–1.75 trillion IPO closing market cap. Skyrocketing demand for Claude models has driven annualized run rates above $60 billion, yet heavy compute commitments exceeding $500 billion and net losses near $80 billion highlight margin pressure and execution risk. Investor expectations have moderated from earlier $2 trillion targets to the $1.5–1.75 trillion range amid equity market volatility and scrutiny of AI infrastructure costs. With the listing slated for mid-November under ticker ANT, near-term pricing will hinge on enterprise adoption momentum versus competitive intensity from OpenAI and hyperscaler alternatives.
