Google’s Gemini 3.5 Pro, teased at I/O in May 2026 with a June target, remains in partner testing as of late August due to repeated shortfalls in coding and agentic performance. Multiple Flash variants (3.6, 3.7, Lite, Cyber) shipped on an accelerated cadence instead, while Google confirmed it has begun pre-training a larger Gemini 4 base model to reach the next frontier. Traders view the 3.5 Pro delay—tied to internal benchmark misses and a late-June training reset—as increasing the chance the company skips ahead or further postpones a Pro release, with upcoming earnings commentary and any partner-testing signals likely to move implied probabilities.

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 be either clearly defined and publicly announced by Google 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 Google, with additional verification from a consensus of credible reporting.
