Description

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.

Frequently asked questions

On Polymarket, the dashboard for the 2nd largest private company market tracks real-time odds, price history, and 24-hour volume of $6,151. It shows how traders price the likelihood of which private company will hold the second-highest valuation by the end of August, with updates reflecting market sentiment and new information.

This market resolves around Sep 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final determination will rely on authoritative valuations or announcements from reputable financial news sources and industry analyses, ensuring an objective and transparent resolution.

Several signals could shift this market before Sep 1, 2026. Major funding rounds, new partnerships, or leadership announcements for competing firms often trigger rapid price changes. Market sentiment driven by broader economic trends or sector-specific news can also influence trader behavior. As the resolution window nears, any verified reports on company valuations — even rumors from credible financial outlets — may cause sharp movements. Traders will be closely watching quarterly earnings reports and high-profile investor activities for directional cues.
