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.
