Recent surges in private-market valuations for OpenAI and Anthropic have lifted trader-implied odds to 63% that their combined figure will exceed Meta Platforms’ market capitalization by June 30. OpenAI closed a record $122 billion round in March at an $852 billion post-money valuation, while Anthropic is advancing talks for a $30–50 billion raise at $900–950 billion—more than double its February $380 billion mark—and secondary shares have traded near $1 trillion. These moves reflect accelerating revenue trajectories and institutional demand for AI exposure. Meta’s equity, trading near $1.55 trillion with a market cap in the same range, offers a public benchmark against which the private AI pair’s momentum is measured. Key catalysts ahead include any finalization of Anthropic’s round and Meta’s next earnings release, both of which could shift the relative valuations before the June 30 snapshot.

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 private company completes an IPO or direct listing prior to 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-hour 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 the 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 last 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.
