Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue. Ages are as of when this page was built.

About this market

Live prediction market odds for "What will OpenAI's frontier output token price hit in 2026?". 45 leads at 38.5%. Next is 40 at 37.5%. $15K has traded across 6 outcomes on Polymarket. The market is expected to resolve by Jan 1, 2027.

This market will resolve to "Yes" if, at any point between market creation and December 31, 2026, 11:59 PM ET, the standard output token price of OpenAI's frontier model is equal to or beyond (above for ↑ High Prices, below for ↓ Low Prices) the price specified in the title, in USD per million tokens. Otherwise, this market will resolve to "No". OpenAI's frontier model means the model with the highest score in the "Artificial Analysis Intelligence Index" (AAII) column of the model leaderboard at https://artificialanalysis.ai/leaderboards/models among entries listing OpenAI as the "Creator". The "Status" filter must be set to "Current", with "Weights", "Size", "Price", and "Reasoning" set to "All". Only models with a standard output token price listed on OpenAI's official API pricing page will be considered. Only models that are publicly accessible, including via open beta or open rolling waitlist signups, will be considered; models available only through a closed beta or any form of private or limited access will not qualify. Where the leaderboard lists one model under several reasoning-effort or configuration settings, those entries count as the same model and its highest displayed score applies. If two or more qualifying models share the highest displayed score, all respective standard output token prices of those models will be considered. Scores will be taken as displayed under the index, regardless of any underlying granular or unrounded data published elsewhere. The relevant price is the “Standard” output token price on OpenAI’s official API pricing page, using the “Short context” rate where context-based pricing differs. Prices for batch, flex, fast mode, priority, long-context, cached, or regional and data-residency variants will not be considered. Any promotional, temporary, or volume-discount pricing will not be used for resolution; only the standard listed API price applies. A price qualifies only while the model meets the frontier definition above, after market creation. A later leaderboard appearance or score change will not cause an earlier price to qualify. The resolution sources for this market will be the Artificial Analysis leaderboard for model scores and OpenAI's official API pricing page (https://developers.openai.com/api/docs/pricing) for prices. Official announcements and archived copies of these pages may be used to confirm the scores, prices, and when they were displayed; 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.
