OpenAI's ChatGPT has demonstrated robust reliability, logging 99.91% uptime for its large language model services from January to April 2026, with no major outages reported in April and only minor elevated failures on March 31 for Enterprise and Edu workspaces. This stability follows February's widespread disruptions affecting thousands, linked to error rates amid high demand, prompting infrastructure upgrades that traders view as reducing near-term outage risks. Competitive pressures from rivals like Anthropic's Claude, which faced AWS-tied downtime in March, underscore OpenAI's edge in scaling. Watch for potential catalysts like unannounced model updates, traffic surges from new features, or backend deploys, which historically trigger issues in AI platforms.

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.
An incident resolved outside this market’s timeframe will only qualify if ongoing at this market’s resolution time, in which case the market will remain open until that incident is marked as “Resolved,” and resolution will be based on the first impact classification thereafter, regardless of subsequent revisions or corrections.
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.
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.
