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 78%.; As of October 12, 2026, Google has released Gemini 4 Argon, but it is currently only available to trusted cybersecurity defenders through the Fairwind Program, not yet fully open to the public, with no specific timeline announced for broader access. Although one report suggests it may open to global users in Q4 2026, public availability has not been achieved as of the evidence date. Thus, the evidence does not establish that Gemini 4.0 will be formally released to the public by the October 15, 2026 deadline.
3. Oct 13, 2026 UTC — The most likely outcome is "No", with a our assessmentestimate of 78%.; As of October 13, 2026, Google has announced Gemini 4 Argon, but it is only being rolled out gradually to trusted cybersecurity testers via the Fairwind program, with general developers and consumers not yet widely able to use it. The report does not clarify whether Gemini 4 Argon is equivalent to Gemini 4.0, nor does it provide a specific date for public availability. Therefore, the current evidence cannot establish whether Gemini 4.0 will be officially released to the public by October 15, 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.
