This market will resolve according to the date on which OpenAI's GPT-5.5 model is made available to the general public (ET). 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.Recent Axios reporting on April 9 revealed OpenAI's plans for a staggered rollout of GPT-5.5—codenamed "Spud," with pretraining completed around March 24—limiting initial access to select companies due to cybersecurity misuse risks, echoing Anthropic's restricted Mythos deployment. This tempers trader consensus, boosting "No release by April 30" to 33% amid safety concerns, while April 16 holds 39% on leaks hinting at a mid-April public launch window (14th-16th) and intensifying hype around Codex super app integration. Competitive pressures from Anthropic and xAI Grok 5 drive urgency, but resolution hinges on official announcements, potential Friday demos, and benchmark validations like ARC-AGI progress, keeping the race tightly contested.
