Morgan Stanley holds the strongest position for lead underwriter on Anthropic’s planned IPO, with market-implied odds reflecting consistent reports that it is favored for the lead-left role. Recent developments include its leadership of the company’s $15 billion credit facility, where top commitments align with expected IPO mandates, alongside Goldman Sachs, JPMorgan, and Citigroup. Anthropic’s confidential S-1 filing in June, surging revenue run rate above $65 billion annualized by July, and Nasdaq listing plans have reinforced the syndicate structure, though the offering has shifted toward a November timeline to incorporate Q3 results. Goldman Sachs is positioned more prominently as stabilization agent rather than primary lead, while other banks trail significantly in disclosed roles. These dynamics underscore how debt financing participation and investor outreach have shaped current pricing ahead of the public registration.

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.
