This market will resolve to the listed company with the larger valuation, as measured by the final NPM Price reported by Nasdaq Private Market, LLC (NPM) and the official closing price for the public company, for December 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 January 1, 2027, this market may remain open until 11:59 PM ET on January 4, 2027. If no further data is released by that time, the market will resolve according to the latest 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 the private company completes an IPO or direct listing before the specified date, this market will resolve according to the company's public market capitalization at the market close of the specified date or the most recent trading day. Public market capitalization will be determined using the final official regular-hours trading price published for the company's primary listed common equity on its primary exchange for the specified date or the most recent trading day, multiplied by the company's total outstanding common shares at the relevant time. 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 the private company is NPM data published here (https://fe.secondmarket.com/companies/company-30839e0b-2730-4495-839f-1bf638fa9cca/data?return_url=https://polymarket.com/finance/privates). 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 OpenAI's valuation is equal to Meta's public market capitalization at resolution, this market will resolve to 50-50. Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data.Meta's market capitalization near $1.48 trillion reflects 33% year-over-year revenue growth in Q1 2026 from its core advertising business, tempered by elevated 2026 capital-expenditure guidance of $125-145 billion for AI infrastructure. OpenAI's March 2026 funding round established an $852 billion post-money valuation, with IPO preparations targeting as high as $1 trillion by September. This balance at 54.5% implied probability for Meta stems from Meta's proven earnings power versus OpenAI's unprofitable but high-growth trajectory and potential re-rating. Key upcoming catalysts include Meta's July 28 earnings release and OpenAI's regulatory filings, which could shift trader consensus on forward revenue multiples and competitive positioning in generative AI.
