Resolution Criteria
Resolves YES if Apple releases an iOS update in 2026 that integrates Google Gemini (or a Gemini-derived model) as a core component of Siri, available to end users on iPhones. The integration must be a shipping product update, not just a developer beta or announcement.
Context: Reports indicate Apple is partnering with Google to integrate Gemini into Siri, targeting an iOS 26.4 release. This would represent a major shift in Apple's AI strategy after Apple Intelligence received criticism.
Resolves NO if no such update ships to end users by December 31, 2026. A beta-only release does not count.
1,000Primary-source check as of Jul 9, 2026 21:06 UTC: Google and Apple's joint statement says the next generation of Apple Foundation Models will be based on Google's Gemini models and will help power a more personalized Siri coming this year. Apple's June 8 Siri AI announcement, however, says developer testing is available now and user availability will be a beta later this year.
That makes the provider leg strongly source-supported, but it does not yet satisfy this market's shipping leg: the criteria explicitly exclude a beta-only release, so YES still needs a non-beta iOS update reaching iPhone end users by Dec. 31. Apple's separate EU delay does not by itself force NO if a qualifying update ships to end users elsewhere.
