Google's Gemini 3.5 Pro remains unreleased as of late August 2026 despite its May 19 I/O announcement framing it as the next flagship large language model with advanced agentic and reasoning capabilities. The DeepMind product page continues to list only Gemini 3.1 Pro (in preview since February) alongside a "3.5 Pro coming soon" badge, while Flash and other 3.5 variants have shipped. Initial rollout targets for June slipped without a confirmed public API endpoint, pricing, or general availability, mirroring historical patterns of Pro-tier delays relative to lighter models. Trader consensus reflected in the 59% probability of no release by September 30 aligns with these repeated timeline shifts and the absence of fresh regulatory, benchmark, or partnership signals that would accelerate deployment. Key near-term watchpoints include any earnings commentary or developer updates that could clarify internal testing progress.

Any Gemini model released after market creation and labeled as "Pro" may qualify (e.g., gemini-3.2-pro, gemini-3.5-pro, or gemini-4.0-pro-preview). Gemini models labeled only as Flash, Flash-Lite, or another non-Pro variant will not qualify.
Products labeled as a GA promotion of an already-existing Preview model (e.g., gemini-3.1-pro-ga) may 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 Google 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.
The primary resolution source for this market will be official information from Google, with additional verification from a consensus of credible reporting.
