Resolution criteria

This market will resolve to YES if Google officially releases Gemini 3.5 Pro (or a higher-tier Gemini model, such as Gemini 3.5 Ultra or Gemini 4.x) for public general availability (GA) or public developer preview between June 1, 2026, and June 30, 2026, 11:59 PM PT.

Otherwise, this market will resolve to NO.

For the purposes of this market:

• "Officially releases" means the model is made accessible to developers via the Gemini API, Google AI Studio, Vertex AI, or to consumers via the Gemini App/Web interface, and is officially announced by Google (such as on the Google Developers Blog or the Gemini API Release Notes).

• Only new distinct model versions count (e.g., Gemini 3.5 Pro or higher). Minor API parameter updates, feature additions to existing models (such as Gemini 3.5 Flash), or the deprecation/sunset of older models do not qualify.

Background

During the Google I/O keynote on May 19, 2026, Google launched Gemini 3.5 Flash and showcased upcoming updates to its model lineup. Google CEO Sundar Pichai announced during the event that the next frontier model, Gemini 3.5 Pro, is slated for release in June 2026.

Gemini 3.5 Pro is expected to introduce a 2-million-token context window alongside Google’s advanced "Deep Think" reasoning mode, which will initially be available through premium subscriptions and enterprise API pathways. This market tracks whether Google meets its June rollout timeline for this flagship upgrade.
