Trader consensus on Polymarket reflects intense anticipation for OpenAI's GPT-5.5 "Spud" large language model release in late April, with implied probabilities tightly clustered around April 27–29 at 31.5% and April 12 at 30.5%, driven by reports of pretraining completion in early April and Sam Altman's March 24 tease of a release "in a few weeks." OpenAI's monthly cadence—GPT-5.4 in March following 5.3 in February—bolsters expectations for an April drop amid competitive pressure from DeepSeek V4 and Grok 5. Differentiators include final post-training optimizations for enhanced reasoning and agentic capabilities, though today's Axios security disclosure introduces minor delay risks. Key swing factor: an imminent announcement could tip odds toward mid-month dates.

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.
