Recent leaks of GPT-5.6 identifiers in OpenAI’s Codex backend logs, combined with the company’s accelerated six-week release cadence following the April 23 launch of GPT-5.5, have positioned mid-June as the leading window in trader sentiment. Internal testing signals, including routing entries and A/B test mentions, suggest the next large language model iteration—expected to deliver gains in reasoning, agentic workflows, and context handling—could reach ChatGPT and API users around June 15–21. Competitive pressure from Anthropic’s Mythos line and historical patterns of rapid OpenAI updates reinforce this timeline, though no official announcement or system card has appeared. Traders assign the highest implied probability (51%) to that period, with later June windows trailing as markets price in the possibility of last-minute testing or delays common in frontier model deployments.

This market will resolve according to the calendar date (ET) on which OpenAI's GPT-5.6 model is made available to the general public.
GPT-5.6 refers to a product explicitly named GPT-5.6, or a variant that is recognized as a direct successor to GPT-5.5, similar to the progression from GPT-5.1 to GPT-5.2. (e.g., GPT-5.7, GPT-5.8, etc., would qualify toward this market)
Qualifying releases of task-specialized models (e.g., GPT-Codex/Transcribe), cost-efficiency variants (e.g., Nano/Mini), or reasoning models of the o-series family will count for this market. Products labeled as a new flagship generation GPT-6 or similar will NOT qualify.
A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice.
The release must be either clearly defined and publicly announced by OpenAI as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within the company’s official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.
The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.Recent leaks of GPT-5.6 identifiers in OpenAI’s Codex backend logs, combined with the company’s accelerated six-week release cadence following the April 23 launch of GPT-5.5, have positioned mid-June as the leading window in trader sentiment.
