Trader consensus on Polymarket heavily favors an April 23 release for OpenAI's GPT-5.5 large language model at 66.5% implied probability, driven by recent leaks revealing the model's codename "Spud" completed pre-training on March 24 at OpenAI's Stargate facility using over 100,000 H100 GPUs, with reported 40% gains in coding, reasoning, and agent tasks over GPT-5.4. Insider confirmations of the GPT-5.5 branding and Greg Brockman's hints at a major qualitative shift have fueled optimism, while OpenAI's strategy of observing competitors like Anthropic's recent Opus 4.6 drop tempers earlier dates. No official announcement yet as of April 16, but cybersecurity concerns may prompt a staggered enterprise rollout first; watch for developer conference teases or API previews this week that could confirm timelines or trigger shifts.

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.
