About this market

Final prediction market prices for "Anthropic valued higher than OpenAI in 2026?". $81K has traded across 0 outcomes on Polymarket. The market closed on Dec 31, 2026.

This market will resolve to “Yes” if, at any point, Anthropic's most recent public or private valuation is greater than OpenAI's most recent public or private valuation, by December 31, 2026 (ET). Otherwise, this market will resolve to “No”. Private valuation refers to the valuation of a company as established in a completed funding round. Qualifying private valuations must be explicitly confirmed by the company whose value is observed, or an overwhelming consensus of credible reporting. Public valuation refers to the company’s market capitalization (number of shares outstanding multiplied by the current share price). The primary resolution source will be official communications from Anthropic and OpenAI; however, a consensus of credible reporting may also be used.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
