Recent confidential IPO filing and selection of Morgan Stanley and Goldman Sachs as lead underwriters have driven the closely matched 38.5% and 37.5% implied probabilities, reflecting their established roles in large-scale technology offerings and deep relationships with high-growth AI firms. JPMorgan's inclusion at 3.0% signals supporting participation, while lower odds for other banks highlight limited mandates amid intense competition for bookrunner positions. This positioning aligns with historical precedent where bulge-bracket institutions dominate mega-IPO syndicates valued near $1 trillion, with potential October timing adding near-term resolution pressure on trader sentiment.

This market will resolve according to the bank that serves as the lead underwriter in the initial public offering of Anthropic.
If no IPO occurs by December 31, 2027, 11:59 PM ET, or Anthropic completes an initial public offering without a designated lead underwriter, this market will resolve to “Other.”
If multiple banks are identified as lead underwriters, this market will resolve according to the primary lead underwriter. If the hierarchy between them is unclear, this market will resolve once it is conclusively evident which bank is the primary lead underwriter, for example, through the order in which the banks are listed in the underwriting section of Anthropic’s final initial public offering prospectus, once released.
The primary resolution source for this market will be official disclosures from Anthropic.
