The October 26 S-1 filing naming Goldman Sachs in the lead-left underwriter position has driven the 90.8% market-implied odds, confirming its role managing the syndicate, pricing, and roadshow for Anthropic’s planned Nasdaq listing. This mirrors Goldman’s prior lead-left assignment on SpaceX’s June IPO and aligns with its competitive standing in 2026 equity capital markets league tables, while Morgan Stanley’s stabilization-agent designation accounts for its minimal share. Trader consensus reflects the binding nature of prospectus disclosures over earlier speculation. The November 9 roadshow and targeted mid-November debut remain key near-term milestones, though any post-filing reallocation or delayed offering could theoretically alter outcomes under resolution criteria tied to final underwriting hierarchy.
