Goldman Sachs holds a narrow lead in trader-implied odds for lead-left bookrunner on Anthropic’s anticipated fall 2026 IPO due to its established dominance in large-cap technology offerings and recent capture of the comparable SpaceX mandate, while Morgan Stanley’s near-parity position stems from its parallel selection alongside Goldman as a top underwriter. Both banks were formally designated in early June reports, with JPMorgan Chase also engaged but commanding far lower implied probability given its secondary role in recent AI-related deals. Anthropic’s confidential S-1 filing and July investor meetings have reinforced expectations for a sizable listing, and the company’s reported 14-fold year-over-year revenue increase in the second quarter has bolstered overall IPO momentum without shifting the relative bank positioning. Upcoming catalysts include further roadshow activity and any final allocation decisions ahead of pricing.

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. A consensus of credible reporting may also be used.
