Will Anthropic's market cap be less than $1.25T at market close on IPO day?

Prediction markets put the probability at 5%: Will Anthropic's market cap be less than $1.25T at market close on IPO day. Currently, markets see this as unlikely (5% YES). The second big market for this event is on Anthropic’s valuation.

What’s Happening

The question of whether Anthropic's market cap be less than $1.25T at market close on IPO day currently sits at 5% YES against 95% NO, tightening from an earlier 11% reading when nine valuation brackets were first quoted. Running the cumulative distribution across those brackets places the median outcome inside the $1.75T to $2.0T range, well above the sub-$1.25T threshold. Individual brackets priced the $1.5T–$1.75T band at 17% and the $2.25T–$2.5T band at 17%, while a debut at $3T or more was quoted at just 3%. The listing timeline itself carries a 68% chance of a public debut by December 31, 2026, with October carrying roughly half that weight. [Actionnetwork, Aug 10]

The valuation anchor rests on rapid revenue scaling. Anthropic's run-rate revenue crossed $47B in May 2026, driven by Claude Code, enterprise API demand, and hyperscaler resale, making it the most valuable private company on Crunchbase's Unicorn Board since SpaceX listed. In H1 2026, global venture funding set a record that beat all of 2025 ($440B), with OpenAI and Anthropic together absorbing $217B of that flow. Comparative multiples underscore why a low-end close looks improbable: Anthropic was benchmarked at a $61.5B valuation on roughly $3B ARR (20x), versus OpenAI at $157B / $11B ARR (14x), before the 2026 revenue surge reset the base.

Historical IPO precedent tempers the downside case but does not eliminate it. The comparable SPCX debut closed near ~$123 on July 22 after opening around $161, a reminder that first-day closes can compress against pre-listing anchors. Analysts have flagged that mega-cap tech valuations may be inflated by as much as $1.25 trillion in certain sum-of-the-parts models, keeping a tail risk that Anthropic's market cap be less than $1.25T at market close on IPO day despite the strong revenue base. For now, the weight of pricing signals the probability that Anthropic's market cap be less than $1.25T at market close on IPO day remains low, contingent on the debut landing before year-end and revenue multiples holding near sector norms.
