Resolution criterion
Yes if Apple ships a stable release of iOS 27 (general public, not developer or public beta) including the rebuilt Siri, evidenced by release notes on support.apple.com or an apple.com/newsroom release.
Verified starting state
Announced at WWDC on 8 June 2026, planned for "fall 2026" as a free update. Google had confirmed in April 2026 that it would arrive in 2026. Apple has already delayed the Siri rebuild several times, including a delay reported in February 2026.
What pushes it up
- iOS 27 was released to the general public on September 14, 2026, and includes the new Siri AI features [2, 5].
- Google confirmed in April 2026 that the Gemini-powered Siri integration would arrive within the 2026 calendar year [1].
- Major press outlets report that the 'smarter Siri' is a core part of the current iOS 27 public release [0, 4].
What pushes it down
- The new Siri AI is currently labeled as being in 'beta' within the stable OS release, which could imply a staggered or incomplete rollout of all Gemini-powered features [3].
- Apple has a documented history of delaying this specific Siri rebuild, with multiple delays reported as recently as February 2026 [1].
What would move this number most
Whether the specific Gemini-powered backend is fully active in the current 27.0 release or if it is slated for activation in a 27.1 or 27.2 update before the end of the year.
