Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. 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.

About this market

Live prediction market odds for "Another Codex outage in 2026?". Yes leads at 96.9%. $1K has traded across 1 outcome on Polymarket. The market is expected to resolve by Jan 1, 2027.

This market will resolve to "Yes" if OpenAI's Codex experiences any incident classified as 'Partial/Full Outage' between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Codex will be considered to have experienced a qualifying incident on the specified day if the OpenAI Status Page for Codex (status.openai.com) displays that day’s status box as a shade of red indicating Partial/Full Outage once it is finalized. (green indicates "No incidents", yellow indicates "Degraded performance"). A day will be considered finalized once the following day’s status box is added on the Status Page. Only incidents listing Codex under 'Affected components' will be considered. Incidents labeled as affecting 'APIs,' 'ChatGPT,' 'FedRAMP,' or 'Ads Platform,' but not Codex, will have no bearing on the resolution of this market. The 'Codex in ChatGPT Desktop' component, listed under ChatGPT, is not part of Codex. This market will remain open until the December 31, 2026 status box is finalized and all incidents that began on that date have been resolved. Revisions that change an incident's impact classification to or from 'Partial/Full Outage' will be considered if the revision is published before the December 31, 2026 status box is finalized or before all incidents that began on that date have been resolved. This market will resolve once the December 31, 2026 status box is finalized, provided no incident that began on that date is ongoing. In case of an ongoing incident the market will remain open until the incident is marked as "Resolved" and all relevant data has been released. If the incident in question is not resolved or all relevant data has not been released by the end of the seventh day after December 31, 2026, this market will resolve based on the data available at that time. The primary resolution source for this market will be official system status information published by OpenAI on status.openai.com; 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.
