Morgan Stanley holds an 81.5% implied probability as lead underwriter for Anthropic’s IPO, reflecting recent reports that it is positioned for the “lead left” role on the deal while also heading the company’s $15 billion pre-IPO revolving credit facility finalized in early September 2026. Goldman Sachs, at 17.5%, is expected to serve as stabilization agent and shares prominent placement alongside JPMorgan and Citigroup in both the credit syndicate and IPO syndicate, consistent with its mandate on the recent SpaceX listing. These assignments align bank commitments in the revolver—where larger lender roles often secure higher-fee IPO positions—with underwriting mandates ahead of a potential late-September S-1 filing and mid-October roadshow. Trader consensus prices in Morgan Stanley’s edge in investor pricing discussions while acknowledging that final lead-left designation remains subject to change before resolution.

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.
