OpenAI's April 23, 2026, launch of GPT-5.5—its most advanced large language model yet, excelling in agentic coding and computer use—has accelerated trader consensus toward an imminent GPT-5.6 rollout, fueled by leaked Codex internal logs showing early testing just days later. This reflects OpenAI's compressed release cadence, from GPT-5 in August 2025 to iterative upgrades every 4-7 weeks, amid fierce competition from Anthropic's Claude Opus 4.7 and Google's upcoming Gemini advancements at I/O on May 19. While no official GPT-5.6 announcement exists, the model's implied superior benchmarks in reasoning and software engineering position OpenAI as the frontrunner, though surprises from xAI's Grok or regulatory hurdles could shift dynamics before mid-June.

GPT-5.6 refers to a product explicitly named GPT-5.6, or a variant that is recognized as a direct successor to GPT-5.5, similar to the progression from GPT-5.1 to GPT-5.2. (e.g., GPT-5.7, GPT-5.8, 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.
