OpenAI's dominant 91% market-implied odds reflect its firmly established position as the second-most valuable private company behind Anthropic, driven by a March 2026 $122 billion funding round that set an $852 billion post-money valuation and an August tender reaffirming that mark amid sustained demand for its GPT large language models and ChatGPT platform. Recent AI sector funding cycles, including Anthropic's $65 billion Series H at $965 billion in May, have locked in the top-two ranking with no material shifts expected before month-end, as revenue run rates and competitive positioning in frontier model development remain stable. A sudden new valuation mark or strategic event for ByteDance or Databricks could theoretically alter the order, though the short timeline and lack of pending catalysts make such outcomes unlikely in traders' consensus view.

This market will resolve to the listed company with the second largest private market valuation on September 30, 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 all business dates in the specified period by 1:00 PM ET on the calendar date following the specified date, this market may remain open until 11:59 PM ET on the third business day following the specified date. 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 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 specified date, this market will resolve based on its final NPM valuation published between market creation and the IPO or direct listing date, as this market is based on private market valuations only.
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 achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution.
If two or more companies are tied for the second highest valuation, the markets will resolve in favor of the company that achieved that valuation first. If the valuations were achieved on the same day, the market will resolve in favor of the company whose listed name comes first alphabetically.
Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data.
