This market asks whether OpenAI’s private valuation will reach at least $800 billion before the end of 2026, using the Nasdaq Private Market (NPM) valuation series as the reference point. It is worth watching because OpenAI is one of the most closely followed private companies in the market, and this threshold is high enough that small changes in the company’s implied valuation path matter.
The question is simple: will OpenAI’s NPM Price, as reported by Nasdaq Private Market, hit or exceed $800 billion on any trading day from market creation through December 31, 2026? The market resolves "Yes" if that valuation threshold is reached in the published NPM data, and "No" otherwise. If OpenAI goes public before then, the rules also allow the market to use the IPO or direct listing price and subsequent public market capitalization as part of the resolution process.
OpenAI’s value is not set by a single public share price, so there is room for uncertainty about how quickly private-market pricing can move over time. Readers care because the company sits at the center of the AI industry, and a move to $800 billion would signal an unusually large jump in implied enterprise value. The market is pricing a disagreement over whether future private transactions, NPM marks, or a public listing will push the valuation to that level before year-end 2026.
The price can move if NPM publishes new valuation data showing OpenAI at or above the $800 billion threshold, since the contract is tied directly to those daily reported marks. Any IPO or direct listing would also matter, because the rules say the official offering price and public-market capitalization can be used if the company lists before the deadline. Changes in the pace of funding rounds, tender offers, or other published pricing events that affect the NPM series could also shift expectations.

View marketThe current market price implies roughly a 72% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.
The key source of truth is the NPM Price published by Nasdaq Private Market, which is updated once daily for trading days and posted the following calendar day at 1:00 PM ET. Readers should check whether OpenAI’s valuation ever meets the $800 billion threshold in the published NPM data before December 31, 2026, and whether any IPO, direct listing, or pause in NPM coverage changes the resolution path. The market may stay open a few extra days in early January 2027 if late-published business-day data is still pending, so the exact publication timing matters as much as the valuation itself.

This market is currently listed with an end date of Jan 1, 2027. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve to "Yes" if OpenAI's private market valuation, as measured by the NPM Price reported by Nasdaq Private Market, LLC (NPM) for any date between market creation and December 31, 2026, reaches or exceeds the listed amount. Otherwise, this market will resolve to "No". 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 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 data available. If NPM ceases publishing relevant data prior to the end of the specified period, this market will resolve based on the NPM data published for the period prior to the cessation of coverage, as well as any applicable public market capitalization data following an IPO or direct listing. If the company completes an IPO or direct listing before the end of the specified period, this market will consider, in addition to the relevant NPM valuations published between market creation and the IPO or direct listing date, the valuation implied by the official IPO or direct listing price, and the company's public market capitalization between the IPO or direct listing date and the end of the specified period. Public market capitalization will be determined using the highest/lowest official regular-hours trading price published for the company's primary listed common equity on its primary exchange for any trading day during the specified period, multiplied by the company's total outstanding common shares at the relevant time. If the listed company merges with or acquires another entity and remains the parent company, no change to resolution methodology applies. If the 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 NPM valuations and applicable public market capitalizations 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/company-30839e0b-2730-4495-839f-1bf638fa9cca/data). 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. Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data.
