This market will resolve to the listed company with the second largest private market valuation on August 31, 2026. NPM Prices are published for trading days only and are updated once daily at 1:00 PM ET on the following calendar day. If NPM has not published relevant data for all business dates in the specified period by 1:00 PM ET on the calendar date following the specified date, this market may remain open until 11:59 PM ET on the third business day following the specified date. If no further data is released by that time, the market will resolve according to the data available. If NPM ceases publishing relevant data prior to the specified date, this market will resolve based on the NPM data published prior to the cessation of coverage, as well as applicable public market capitalization data following an IPO or direct listing. If a company completes an IPO or direct listing before the specified date, this market will resolve based on its final NPM valuation published between market creation and the IPO or direct listing date, as this market is based on private market valuations only. If a listed company merges with or acquires another entity and remains the parent company, no change to resolution methodology applies. If a listed company is acquired, merges into another entity and is no longer the surviving parent company, or otherwise ceases to exist as an independent entity prior to the end of the period, only the NPM valuation achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution. If two or more companies are tied for the second highest valuation, the markets will resolve in favor of the company that achieved that valuation first. If the valuations were achieved on the same day, the market will resolve in favor of the company whose listed name comes first alphabetically. Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data. The resolution sources for this market are: https://fe.secondmarket.com/companies/company-c62b8140-fdeb-428d-a9a6-d04eb3b24b49/data https://fe.secondmarket.com/companies/company-3e197763-4ff8-4d8c-bd1f-cc2792937757/data https://fe.secondmarket.com/companies/company-5e0e75a3-96d6-4893-8f23-9d9bac0ec1db/data https://fe.secondmarket.com/companies/company-53787f17-a704-47a9-895a-cb54833bdb1f/data https://fe.secondmarket.com/companies/company-625e5f47-7ff7-45c4-be95-0305665164bd/data https://fe.secondmarket.com/companies/company-ab5413cb-1c83-497e-b03e-2ed7ca70117d/data https://fe.secondmarket.com/companies/company-86eda4f2-01af-4275-9c70-0ff3c347c62b/data https://fe.secondmarket.com/companies/company-782c0a32-4727-4097-a40b-9a2602f243e7/data https://fe.secondmarket.com/companies/company-30839e0b-2730-4495-839f-1bf638fa9cca/data https://fe.secondmarket.com/companies/company-802a7f97-3625-4614-a13d-d999cf139330/data https://fe.secondmarket.com/companies/company-6edded11-6786-4392-9695-3cce6fda0de0/data.OpenAI's $852 billion valuation, confirmed by its March 2026 funding round and August secondary share sale, drives the overwhelming market consensus that it holds second place among private companies behind SpaceX. Traders see little scope for meaningful re-ranking by month-end given the brief remaining window and OpenAI's sustained capital inflows, AI model leadership, and demonstrated revenue scale. While an outsized new round or valuation reset at a rival such as Anthropic could theoretically intervene, the probability remains low absent major unexpected announcements before August 31.
