Morgan Stanley’s commanding 81% market-implied probability stems from its leadership of Anthropic’s $15 billion pre-IPO revolving credit facility and recent investor pricing discussions, positioning the bank for the lead-left underwriter role on the planned Nasdaq listing. Goldman Sachs, at 18%, is widely expected to serve as stabilization agent, a lucrative assignment consistent with its recent mandates. JPMorgan, Citigroup, and others trail at under 1% each after securing supporting positions in the credit syndicate. With the S-1 filing now targeted for late September and marketing eyed for mid-October, these assignments reflect the banks’ capital commitments and deal-team allocations ahead of a potential multi-billion-dollar offering valued near $2 trillion.

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.
