**Ongoing delays in Gemini 3.5 Pro, originally targeted for a June 2026 launch after Google I/O, continue to drive the 68.5% market-implied probability of no Pro release by September 30.** The model has missed multiple internal windows due to shortfalls in coding and agentic performance, with Google confirming partner testing only and no firm availability date as of late August. Recent activity has instead focused on frequent Flash iterations, including Gemini 3.7 Flash in mid-August, alongside confirmation that pre-training for the next-generation Gemini 4 has begun. Traders appear to weigh the pattern of repeated slips and lack of new Pro-specific updates more heavily than any near-term resolution catalyst.

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.
