Goldman Sachs holds a 57.5% market-implied probability of serving as lead left bookrunner for Anthropic’s IPO, ahead of Morgan Stanley at 26.5%, reflecting their established dominance in large-scale technology offerings and recent positioning. Both banks were formally selected as joint leads following Anthropic’s confidential S-1 filing in early June 2026 and its $65 billion Series H round at a $965 billion valuation. Goldman’s edge stems from its successful lead-left role on the contemporaneous SpaceX IPO and stronger historical market share in AI-related mandates, while Morgan Stanley benefits from deep relationships with the company’s hyperscaler backers. Separate deal teams at each firm have been established to manage conflicts with the parallel OpenAI process, underscoring the mandate’s scale and the banks’ incentives to secure the higher-fee lead position amid expected fall 2026 timing dependent on market conditions.

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.Goldman Sachs holds a 57.5% market-implied probability of serving as lead left bookrunner for Anthropic’s IPO, ahead of Morgan Stanley at 26.5%, reflecting their established dominance in large-scale technology offerings and recent positioning.
