Will Google release Gemini 4.0 by Oct 16, 2026?

Earlier updates

The chart shows our estimated outcome probabilities at each complete assessment.

1. Oct 12, 2026 UTC — Public tracking started; no independent probability estimate yet.; Starting public context: This market will resolve to "Yes" if Google's Gemini 4.0 Flash model is made available to the general public by the listed date. Otherwise, this market will resolve to "No". 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. 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.
2. Oct 12, 2026 UTC — The most likely outcome is "No", with a our assessmentestimate of 64%.; As of October 12, 2026, the available evidence indicates that Google Gemini 4 has not been officially released. Reports from September 25 state that the DeepMind head said Gemini 4 is in the post-training phase and hoped for a release well before year-end, but no specific date was given. A September 20 source explicitly lists Gemini 4 as not yet released, with no public product, model page, or API ID. These reports provide no confirmation of an official release or public access by October 16, so they cannot establish that a release will occur by then.
3. Oct 13, 2026 UTC — The most likely outcome is "Yes", with a our assessmentestimate of 72%.; As of October 12, 2026, one report states that Google announced the first Gemini 4 model on September 30 and says 'Gemini 4 is here,' but it provides no details on public access or an official announcement. Reports from September 25 only indicate that Gemini 4 is in early post-training and Google hopes to release it soon, without confirming a release date. This evidence is insufficient to confirm whether a public release accessible to all occurred before October 16, 2026.
4. Oct 13, 2026 UTC — The final market result has been verified; this question is closed.; Final outcomes come from confirmed market winners or on-chain payouts, not a new model forecast.
