Morgan Stanley’s commanding 65.5% implied probability reflects its lead-arranger role in Anthropic’s recently expanded $15 billion revolving credit facility, where it anchored the largest commitments alongside Goldman Sachs, JPMorgan, and Citigroup. This structure mirrors pre-IPO financing precedents and directly ties debt participation tiers to expected underwriting hierarchy, giving Morgan Stanley the edge in valuation discussions and “lead left” positioning ahead of a potential late-September filing and mid-October Nasdaq listing. Goldman Sachs holds a secondary but meaningful role as stabilization agent, while lower probabilities for JPMorgan and others mirror their smaller credit commitments and limited recent deal momentum. Trader consensus prices in these capital-market alignments over broader sector competition with OpenAI.

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.
