Anthropic holds overwhelming trader consensus as the largest private company by valuation through August 31, driven by its May 2026 Series H round that closed at a $965 billion post-money valuation, eclipsing OpenAI’s prior $852 billion mark from March. Sustained revenue momentum, with annualized run rates reported near $65 billion and strong enterprise adoption of its Claude large language models, has reinforced this lead amid the broader AI competitive landscape. No other private firm, including defense-focused Anduril or search specialist Perplexity, has approached comparable scale in recent funding or performance data. A realistic challenge would require an outsized, last-minute capital raise by OpenAI or another contender before month-end, or an unanticipated IPO by Anthropic itself—both viewed as low-probability events given announced timelines and market conditions.

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 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.
