Trader consensus on Polymarket heavily favors a GPT-5.5 release in mid-to-late April, with April 16 (43.5%) edging out April 23 (38.0%) amid leaks that OpenAI's frontier model codenamed "Spud"—likely GPT-5.5—completed pretraining on March 24, 2026, prompting CEO Sam Altman's "few weeks" timeline. This aligns early dates like the 16th with rumored rollout windows from internal sources, while slight delays to the 23rd or 30th reflect caution over post-training refinements, safety evaluations, and red-teaming to mitigate risks seen in prior launches like GPT-5. Competitive pressure from Anthropic's Claude iterations and Google's Gemini updates accelerates the race, but phased rollouts to select users first could shift odds; watch OpenAI's blog or dev announcements for catalysts breaking the tight race.

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.
