  Wide spread — 17.0¢

  Bid-ask spread is wide enough that intraday moves overstate any tradeable advantage. Most of the headline pp move would be eaten by spread on a market order.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

This market will resolve to the number of calendar days on which OpenAI's ChatGPT experiences any incident classified as 'Partial/Full Outage' as of the time it is marked as “Resolved” during May 2026 (ET). Only incidents listing ChatGPT under 'Affected components' will be considered. Incidents labeled as affecting 'APIs,' or 'Sora,' but not ChatGPT, will have no bearing on the resolution of this market. Classifications of an incident while it is ongoing will have no bearing on the resolution of this market. Only classifications of events that are resolved will be considered. Qualifying incidents include outages and other issues classified as 'Partial/Full Outage' when they are resolved, during this market's above-specified timeframe. Revisions that upgrade an incident’s impact classification to 'Partial/Full Outage' will qualify if the incident was resolved and the revision is published within this market’s timeframe. This market will resolve at 12:00 PM ET on the day following the specified timeframe, provided no incident that began during the specified timeframe is ongoing, and all relevant data has been released. If either condition is not met, the market will remain open until the incident is marked as “Resolved” and all relevant data has been released. If all relevant data has not been released by the end of the seventh day after the specified timeframe, 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.
