This market will resolve to "Yes" if OpenAI's GPT-5.5 model is made available to the general public by the specified date (ET). Otherwise, this market will resolve to "No." GPT-5.5 refers to a product explicitly named GPT-5.5, or a variant that is recognized as a direct successor to GPT-5.4, similar to the progression from GPT-5.1 to GPT-5.2. (e.g., GPT-5.6, GPT-5.7, 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 official release of GPT-5.5 on April 23, 2026, drives overwhelming trader consensus toward the company as the model originator, with immediate availability in ChatGPT for Plus, Pro, Business, and Enterprise users, plus Codex integration. This large language model excels in agentic tasks like coding (82.7% on Terminal-Bench 2.0), knowledge work (84.9% GDPval), and multi-tool workflows, outperforming Anthropic's Claude Opus 4.7 and Google's Gemini 3.1 Pro on key benchmarks while matching GPT-5.4 speed and efficiency. Following rapid iterations like GPT-5.4 in March, it underscores OpenAI's iterative deployment strategy amid intensifying AI competition; traders eye GPT-5.5 Pro rollout and safety evaluations as near-term catalysts for further positioning.
