Recent funding rounds and valuation updates have left Anthropic and OpenAI trading neck-and-neck near the top of private-company rankings, with Anthropic recently reported above $900 billion and OpenAI at $852 billion, creating tight uncertainty around which will hold the number-two spot by month-end. Other listed contenders such as Stripe, Databricks, and Anduril sit at substantially lower levels, while factors including potential IPO filings, new primary rounds, or revenue disclosures could quickly shift relative positioning. Traders appear to weigh the possibility of last-minute capitalization events against the historical pattern of AI labs attracting outsized private capital ahead of public listings.

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.
