Google confirmed on July 21, 2026, that pre-training for its next flagship large language model, Gemini 4, had begun as the company’s “most ambitious pre-training run yet,” following the recent general availability of Gemini 3.7 Flash. With no model card, API access, or release date announced as of mid-August 2026, trader sentiment reflects the typical 3–5 month training-plus-post-training timeline that pushes any launch no earlier than late Q4 2026 or Q1 2027. Competitive pressure from OpenAI and Anthropic continues to influence Google’s cadence, while upcoming developer events and potential I/O-style showcases remain the key catalysts that could accelerate or further delay the frontier model’s arrival.

For this market to resolve to "Yes," Gemini 4.0 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 clearly defined and publicly announced by Google as being accessible to the general public.
If a qualifying model is made publicly accessible and explicitly labeled with the relevant version name within the company’s official website, this will qualify as “publicly announced”. 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 under the rules will not qualify.
Gemini 4.0 refers to a product explicitly named Gemini 4.0 or one that is recognized as a successor to Gemini 3 similar to the progression from Gemini 2.0 to Gemini 3. Products labeled as Gemini 3.0 Flash, Gemini 2.5, or similar will not count for this market's resolution.
The primary resolution source for this market will be official information from Google, with additional verification from a consensus of credible reporting.
