This market will resolve to the listed company with the largest private market valuation on July 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 the specified date by 1:00 PM ET on August 1, 2026, this market may remain open until 11:59 PM ET on August 4, 2026. 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 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.Traders see roughly even odds across Kraken, Epic Games, Stripe, Anthropic, Lambda, OpenAI, and others because rapid AI-driven valuation swings and potential late funding or tender offers could reorder the private-company hierarchy by July 31. Anthropic’s May 2026 $65 billion round at a $965 billion post-money valuation briefly overtook OpenAI’s $852 billion mark, highlighting how revenue trajectories—now exceeding $47 billion annualized for Anthropic and strong growth at OpenAI—directly influence secondary-market pricing. Stripe and Databricks sit at lower but still substantial levels around $140–180 billion, while gaming and crypto names like Epic and Kraken face slower-moving catalysts. With no major IPOs or rounds confirmed in the immediate window, market-implied odds reflect uncertainty over which firm’s next data point on adoption, compute spend, or investor appetite will shift relative positioning before month-end.
