Will OpenAI's valuation hit __ by December 31?

Resolution Criteria

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?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. Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data.

Prediction markets tracking OpenAI's private valuation through December 2026 show volume heavily concentrated around the $1.0T–$1.5T range, with the $900B and $1.0T thresholds the most heavily backed to resolve 'Yes'. Resolution depends on the NPM Price reported by Nasdaq Private Market for any trading day through 31 December 2026, with a fallback window extending to 4 January 2027.

Market structure

Fifteen discrete threshold outcomes span from below $500B to above $5.0T, creating a ladder of resolution targets. Volume is heavily concentrated in the $900B–$1.25T band, which represents the most contested territory. Above $2.0T, backing drops sharply and thresholds become progressively less supported. Resolution source is Nasdaq Private Market's NPM Price data, supplemented by public market capitalisation data if an IPO or direct listing occurs before the deadline.

Background

OpenAI reached a reported private valuation of $157B in late 2024 during a funding round led by Thrive Capital, and has grown rapidly into one of the most highly valued private technology companies globally. The organisation is in the process of restructuring from its original non-profit governance model into a capped-profit and then a public benefit corporation structure, a transition that has drawn regulatory scrutiny and internal debate. The pace of that restructuring, alongside competitive pressure from Anthropic, Google DeepMind, and Meta's AI divisions, has made OpenAI's valuation trajectory a closely watched signal for the broader artificial intelligence sector. Secondary market trading through platforms such as Nasdaq Private Market provides a mechanism for tracking implied valuation between formal funding rounds.

Key factors

Several structural factors bear on where OpenAI's NPM-reported valuation lands by year-end 2026. First, the timing and terms of any new primary funding rounds directly set reference valuations that secondary markets typically follow. Second, revenue growth from enterprise API contracts and consumer products such as ChatGPT influences investor sentiment in secondary trading. Third, completion or delay of the corporate restructuring into a for-profit entity affects the pool of eligible institutional buyers and the legal clarity of share ownership. Fourth, a potential IPO or direct listing would shift resolution methodology to public market capitalisation, which could be more volatile than private secondary prices. Fifth, the competitive landscape — particularly rival foundation model releases and any regulatory restrictions on AI development in major jurisdictions — could compress or expand perceived addressable markets. Sixth, macro conditions including interest rates and technology sector sentiment shape risk appetite for high-multiple private assets generally. Each of these factors operates independently and their combined direction is not predetermined.
