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. A consensus of credible reporting may also be used.
Morgan Stanley holds a 71% implied probability in the Polymarket market for lead underwriter on Anthropic’s IPO, reflecting its recent positioning as the frontrunner for the “lead-left” role. September 2026 reporting indicates the bank is leading pricing discussions with institutional investors and spearheading a $15 billion revolving credit facility expansion, alongside Goldman Sachs and JPMorgan. Goldman Sachs, at 27% implied probability, is expected to serve as stabilization agent. These assignments follow Anthropic’s June 2026 confidential S-1 filing and $965 billion valuation round, with marketing now targeted for mid-October. Trader consensus prices in the two banks’ established technology IPO track records and syndicate roles while assigning negligible odds to other participants given the concentrated mandate.
