Anthropic’s May 2026 Series H round at a $965 billion post-money valuation—backed by a $47 billion annualized revenue run-rate—established a durable lead over OpenAI’s $852 billion March 2026 mark and subsequent secondary pricing near $894 billion. Strong enterprise adoption of Claude, hyperscaler compute commitments, and secondary-market premiums reaching $1.32 trillion reflect sustained momentum in revenue growth and capital efficiency that markets continue to reward. Both companies have filed confidential S-1s ahead of potential 2026–2027 IPOs, yet Anthropic’s faster revenue trajectory and tighter revenue multiple keep implied odds elevated. A decisive OpenAI IPO re-rating or material Anthropic execution shortfall on compute or model releases remain the clearest paths that could narrow the gap before December 31.

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 available data.
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 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 this market is NPM data published here (https://fe.secondmarket.com/companies/company-3e197763-4ff8-4d8c-bd1f-cc2792937757/data?return_url=https://polymarket.copilot.markets/finance/privates) and here (https://fe.secondmarket.com/companies/company-30839e0b-2730-4495-839f-1bf638fa9cca/data?return_url=https://polymarket.copilot.markets/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 Anthropic's valuation is equal to OpenAI's valuation 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.
