OpenAI's Codex coding agent has already experienced multiple service disruptions in 2026, including a full 56-minute outage on September 25 that halted the web app, API, CLI, and VS Code extension due to an internal issue, followed by elevated errors across Codex, ChatGPT, and related APIs on September 29. These incidents, resolved through mitigations and accompanied by usage limit resets for paid users, highlight ongoing operational challenges with authentication, scaling, and component reliability in the large language model infrastructure. With three months remaining in the year and a track record of intermittent degraded performance, traders see strong likelihood of at least one more outage before year-end, though stable periods could still emerge absent major updates or usage spikes.
