Morgan Stanley's dominant 88.5% implied probability in the Polymarket market reflects its lead-left positioning, driven by its role anchoring Anthropic's September 2026 $15 billion credit facility alongside Goldman Sachs, JPMorgan, and Citigroup—the same banks expected to lead the IPO syndicate. This pre-IPO financing structure, modeled on SpaceX's approach, ties larger lending commitments to underwriting mandates and fees. Recent developments include Anthropic's October investor-day updates showing sequential revenue growth to $16.8 billion in Q3 with positive free cash flow, plus ongoing roadshow preparations targeting a mid-November listing after prior delays. Trader consensus prices in Morgan Stanley's edge from pricing discussions and allocation control, while lower odds for Goldman Sachs at 5.7% align with its expected stabilization-agent role amid the compressed timeline before year-end.
Rules
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.
