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.

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 "Longest GitHub critical incident in October?". 3-6 hours leads at 81.9%. Next is 6-12 hours at 17.8%. $29K has traded across 3 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.

This market will resolve according to the duration of the longest qualifying incident that begins between October 1, 2026, 12:00 AM ET and October 31, 2026, 11:59 PM ET. If no qualifying incident begins during this period, this market will resolve to the lowest bracket (“<1 hour”). An incident will qualify if the official GitHub Status Page (githubstatus.com) or the official GitHub Status API (githubstatus.com/api) classifies the incident's impact as "critical," unless its affected components, once the incident is marked "Resolved," consist solely of Copilot and/or Copilot AI Model Providers. Incidents listing no affected components will qualify. GitHub classifies incident impact as None, Minor, Major, or Critical; only Critical will qualify. Component status labels (e.g. "Degraded Performance," "Partial Outage," or "Major Outage") will have no bearing on this market absent a qualifying critical incident. Revisions published after an incident is marked “Resolved” will not be considered. An incident's duration is the time between its official start timestamp and the time the incident is marked “Resolved,” as published by the GitHub Status Page or the GitHub Status API. An incident will be attributed to the month in which it begins, based on its official start timestamp converted to Eastern Time (ET); an incident that begins during the period and is resolved after the period ends will count in full. If the determined value falls exactly on the boundary between two brackets, this market will resolve to the higher bracket. If an incident that began during the period remains unresolved at the end of the period, this market will remain open and resolve at the earlier of: (i) when the incident is officially resolved, or (ii) the end of the seventh calendar day (ET) after the end of the period, at which point the market will resolve based on the official information available at that time, with any unresolved incident's duration measured from its official start timestamp to that time. Incidents whose affected components, once the incident is marked "Resolved," consist solely of Copilot and/or Copilot AI Model Providers will not qualify. Scheduled maintenance will not qualify. The primary resolution source for this market will be official GitHub system-status information published at https://www.githubstatus.com/, including the official GitHub Status API (https://www.githubstatus.com/api); 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.
