This market will resolve to "Yes" if OpenAI's GPT-5.6 model is made available to the general public by the specified date (ET). Otherwise, this market will resolve to "No." 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 a "Yes" resolution to 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. For this market to resolve to "Yes," 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.OpenAI's recent release of GPT-5.5 on April 23, 2026—its smartest frontier large language model yet, with enhanced agentic capabilities, reduced hallucinations, and top scores on Terminal-Bench 2.0—has traders eyeing a swift follow-up for GPT-5.6, already spotted in Codex logs and internal tools. This reflects OpenAI's accelerated iteration pace since GPT-5's August 2025 debut, outpacing rivals like Anthropic's Claude Mythos and Google's Gemini amid fierce AI competition. No official GPT-5.6 announcement exists, but speculation points to a potential drop around Google I/O on May 19 or mid-June, with today's GPT-5.5-Cyber rollout signaling ongoing advancements; watch for API availability or DevDay teasers in September.
