Anthropic's rapid revenue acceleration to a $65 billion annualized run rate by late July 2026, paired with its $965 billion May valuation after the Series H round, has narrowed the gap with OpenAI's $852 billion mark and $40 billion-plus run rate, creating near-even trader odds on which firm achieves greater valuation growth by month-end. OpenAI's broader consumer adoption via ChatGPT, Microsoft Azure integration, and enterprise momentum help sustain balance despite trailing in recent ARR growth. Key swing factors include progress on confidential IPO filings targeting September 2026, potential flagship model updates like Claude Opus iterations or GPT-5 enhancements that could shift capability benchmarks, and any new infrastructure or partnership announcements that alter revenue trajectories in the final weeks.

This market will resolve to the listed company with the larger percentage increase in private market valuation, as measured by the final NPM Price reported by Nasdaq Private Market, LLC (NPM), from the last trading day prior to the specified month (starting valuation) to last trading day of the specified month (ending valuation).
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 the calendar date following the specified month, this market may remain open until 11:59 PM ET on the third business day following the specified month. 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 end of the specified month, this market will resolve according to the company's public market capitalization at the market close of the specified date.
Public market capitalization will be determined through appropriate calculation using the final official regular-hours closing prices published for the company's listed equities on its primary exchange for the specified date, multiplied by the company's total number of shares outstanding at the relevant time. If necessary, to accurately capture the company’s total market capitalization, rather than a stock-class-specific market capitalization, the calculation will include all outstanding share classes and apply any stated conversion ratios to the publicly traded class. Where no conversion right exists, such shares will be counted at their stated outstanding amount without discount, unless official filings explicitly specify differently. The number of outstanding shares will be determined from official company filings or disclosures (e.g., SEC filings).
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/data?start_date=2026-08-31&view=change&companies=company-3e197763-4ff8-4d8c-bd1f-cc2792937757%2Ccompany-30839e0b-2730-4495-839f-1bf638fa9cca). 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 unrounded percentage increase in valuation is equal to OpenAI's percentage increase in valuation at resolution, this market will resolve to 50-50.
