OpenAI executive Tibo recently signaled additional Codex usage-limit resets for paid users this week following the September 26 global reset after an outage, creating the main catalyst behind the evenly matched Polymarket odds. Codex, OpenAI’s large language model for coding tasks, resets weekly allowances on personal 5-hour and rolling windows while discretionary global or banked resets occur irregularly—roughly every 2–7 days on average—often tied to model launches like GPT-6 Sol and Luna, user milestones, or quality fixes. Historical patterns since mid-2025 show 55 such events, with recent cadence pointing to 1–3 possible this week, though exact timing and scope remain uncertain due to OpenAI’s ad-hoc approach rather than fixed schedules. Traders weigh the explicit “more resets coming next week” signal against variability in announcement volume and any new competitive or technical developments.
