Intro

This market tracks whether OpenAI's private valuation will reach $900 billion or higher at any point through the end of 2026. On Polymarket, the probability of this outcome hitting that threshold stands at 73.5%. Resolution will be determined by Nasdaq Private Market valuations reported through December 31, 2026, with the market potentially remaining open until January 4, 2027 to allow for final NPM data publication. Watch for any IPO or direct listing announcement, which would shift resolution methodology to public market capitalization data.

Polymarket

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.

Frequently asked questions

Prediction market odds on Polymarket reflect real-time consensus from thousands of traders with financial incentives to forecast accurately, whereas traditional analyst forecasts often rely on periodic reports and subjective valuations. Market-derived probabilities tend to incorporate breaking news and funding announcements faster than analyst updates. Comparing Polymarket odds to published analyst price targets and venture capital sentiment can reveal whether traders are more bullish or bearish than the consensus view. This comparison helps identify whether the market is pricing in optimistic growth assumptions or discounting execution risks that analysts may overlook.

On Polymarket, this event is priced using an automated market maker model where traders buy and sell outcome shares. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The top outcome currently reflects an implied probability of 71.5%, meaning the market assigns that likelihood to OpenAI reaching the specified valuation by the deadline. Prices fluctuate based on order flow and inventory imbalances; large trades move odds more sharply when liquidity is thin. Traders profit by correctly predicting whether OpenAI's valuation will cross the threshold, incentivizing information aggregation and continuous price discovery throughout the event window.

The market resolves on Jan 1, 2027, at which point the outcome is determined by whether OpenAI's valuation has reached the specified threshold by December 31. Resolution depends on verified valuation data from credible sources such as funding announcements, secondary market transactions, or official company statements. Traders should monitor OpenAI news, funding rounds, and market developments leading up to the deadline. The binary outcome—either the valuation target is met or it is not—determines which outcome shares settle to full value and which expire worthless.

Major catalysts include new funding rounds, secondary share sales, or official valuation updates from OpenAI or its investors. Product launches, revenue milestones, and competitive developments in generative AI can shift market expectations about the company's growth rate and investor appetite. Macroeconomic conditions, venture capital sentiment, and regulatory announcements also influence perceived risk and valuation multiples. Geopolitical events affecting AI policy or tech sector funding could accelerate or dampen investor enthusiasm. Traders should track earnings reports from OpenAI's partners, board announcements, and insider commentary to anticipate valuation movements before the December 31 deadline.
