This market will resolve to the listed company with the largest percentage increase in private market valuation, as measured by the final NPM Price reported by Nasdaq Private Market, LLC (NPM), from the last trading day prior to the specified month (starting valuation) to last trading day of the specified month (ending valuation). 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 the calendar date following the specified month, this market may remain open until 11:59 PM ET on the third business day following the specified month. If no further data is released by that time, the market will resolve according to the latest available data. 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 end of the specified month, this market will resolve according to the company's public market capitalization at the market close of the specified date. Public market capitalization will be determined through appropriate calculation using the final official regular-hours closing prices published for the company's listed equities on its primary exchange for the specified date, multiplied by the company's total number of shares outstanding at the relevant time. If necessary, to accurately capture the company’s total market capitalization, rather than a stock-class-specific market capitalization, the calculation will include all outstanding share classes and apply any stated conversion ratios to the publicly traded class. Where no conversion right exists, such shares will be counted at their stated outstanding amount without discount, unless official filings explicitly specify differently. The number of outstanding shares will be determined from official company filings or disclosures (e.g., SEC filings). 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 and applicable public market capitalization achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution. The resolution source for this market is NPM data published here (https://fe.secondmarket.com/companies/data?start_date=2026-07-31&view=change&companies=company-3e197763-4ff8-4d8c-bd1f-cc2792937757%2Ccompany-30839e0b-2730-4495-839f-1bf638fa9cca%2Ccompany-53787f17-a704-47a9-895a-cb54833bdb1f%2Ccompany-6edded11-6786-4392-9695-3cce6fda0de0%2Ccompany-f364d2ab-34b7-48c9-a2b7-af62da804953). The resolution source for any period following an IPO, direct listing, or relevant corporate action, will be official exchange trading data and publicly reported share counts. If two or more companies have the same unrounded percentage increase in valuation at resolution, and that percentage increase is the highest among all companies in the market, the market will resolve to the company with the highest valuation. Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data.ByteDance leads the market at 64% implied probability due to explosive private valuation marks that climbed from $330 billion in its August 2025 employee buyback to $480–550 billion in late 2025 and early 2026 secondaries, fueled by $186 billion in 2025 revenue, projected $50 billion profits, and January 2026 U.S. approval of TikTok’s restructuring that cleared major regulatory risk. Databricks follows at 33.5% on repeated AI-driven rounds that lifted it from $100 billion in 2025 to $134 billion by February 2026 and toward $165–188 billion later that summer amid $5.4 billion-plus annualized revenue run rates. OpenAI, Anthropic, and Stripe trail as their already-elevated absolute valuations—OpenAI near $850 billion post-March 2026 round, for instance—reflect slower percentage growth trajectories relative to the leaders’ momentum.
