Will Anthropic's market cap be between $1.5T and $1.75T at market close on IPO day?

Prediction markets put the probability at 16%: Will Anthropic's market cap be between $1.5T and $1.75T at market close on IPO day. Currently, markets see this as unlikely (16% YES). The second big market for this event is on Anthropic’s valuation.

What’s Happening

Polymarket's valuation ladder for Anthropic's public debut currently prices the question of whether Anthropic's market cap be between $1.5T and $1.75T at market close on IPO day at roughly 16% YES against 84% NO, a slight softening from the 17% quoted in early August. The bracket sits within a nine-tranche distribution that spans from below $1.25 trillion (priced near 11%) to $3 trillion or more (roughly 3%). Running the cumulative distribution across all brackets, the implied median outcome lands inside the $1.75T to $2.0T tranche, one step above the $1.5T–$1.75T band and a key reason the specific $1.5T–$1.75T question trades as a minority outcome.

The pricing reflects a steep step-up from Anthropic's last private mark of $965 billion, set in a $65 billion Series H-1 in May 2026. For the $1.5T–$1.75T outcome to resolve YES, the IPO-day close would need to represent roughly 55% to 80% appreciation over that final private round — a first-day valuation jump consistent with recent AI-sector enthusiasm but toward the lower end of the market's expected range. By comparison, SpaceX's reported IPO valuation estimates clustered in the same $1.5 trillion to $1.75 trillion band after its confidential SEC draft filing on April 1, 2026, underscoring how the $1.5T–$1.75T zone has become a common anchor for the largest private-to-public transitions.

Whether Anthropic's market cap be between $1.5T and $1.75T at market close on IPO day hinges on final pricing terms the board has yet to disclose, alongside broader macro conditions at listing. Deeper liquidity in Anthropic-linked contracts has made the consensus harder to move on thin flows, meaning the distribution is likely to compress only once a formal price range and share count are filed. Traders will watch for the registration statement, comparable AI multiples, and any pre-IPO valuation revisions above the $965 billion mark as the next catalysts before the close-day snapshot settles the tranche.
