OpenAI’s GPT-5.6 Sol, the current flagship reasoning model in the 5.x generation, reached public release on July 9, 2026, following a limited preview on June 26 amid U.S. government AI safety review. Traders view the next Sol-tier release (5.7+) as unlikely before late 2026 or 2027 because the company is still iterating on 5.6 capabilities—such as the August 2026 ChatGPT updates for improved factuality and thinking-time controls—while deprecating older snapshots. Competitive pressure from Claude and Gemini models, combined with OpenAI’s pattern of quarterly-to-biannual capability jumps and regulatory scrutiny on frontier releases, anchors market-implied odds toward a measured timeline. Key catalysts ahead include any major developer conference announcements or API deprecation schedules that could signal a new Sol variant.

This market will resolve to "Yes" if OpenAI's next GPT Sol model (5.7+) is made available to the general public between market creation and the specified date (ET). Otherwise, this market will resolve to "No".
A qualifying model must have a name or model identifier that includes "GPT" and "Sol" and be designated as version 5.7 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 5.7 or higher named in the same manner as GPT-5.6 Sol would qualify, including a new whole-number generation such as GPT-6 Sol or an Astra-branded release meeting these criteria, while models whose name does not include "Sol" or which retain a version designation below 5.7, such as GPT-5.6 Sol, GPT-5.6 Terra, or GPT-5.6 Luna, will not qualify. Fine-tunes, modes, or restricted-access variants of an existing version, such as GPT-5.6-Cyber or GPT-5.6 Sol Ultrafast, will not qualify.
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 either be clearly defined and publicly announced by OpenAI as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on 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.
