Trader consensus on Polymarket has coalesced around an implied 74.5% probability for OpenAI releasing GPT-5.5—codenamed "Spud"—on April 23, fueled by credible leaks confirming pretraining completion on March 24, 2026, and CEO Sam Altman's "few weeks" timeline hint. This positions it as a major large language model upgrade emphasizing omnimodal capabilities and agentic reasoning, amid intensifying competition after Anthropic's Opus 4.7 launch on April 16. No official announcement has materialized despite recent OpenAI updates on Codex and cybersecurity tools, but historical patterns of swift post-training rollouts sustain optimism. "No release by April 30" lingers at 5.8% amid risks of delays from safety evaluations or red-teaming, with resolution hinging on any pre-weekend confirmation.

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.
