Apple may yet deliver the first taste of its long-overdue Gemini-powered Siri overhaul before March ends \u2014 but only barely. A timeline analysis published by 9to5Mac on March 20 laid out a scenario in which a rapid succession of software releases over the final days of the month could carry the feature to users before April. The window is razor-thin, and it hinges entirely on Apple\u2019s willingness to move at an unusually compressed pace.
The upgrade would mark the first meaningful AI overhaul to Siri since Apple announced Apple Intelligence at WWDC 2024 \u2014 a reveal that promised a transformed assistant but has repeatedly shipped features ahead of the headline act. The Gemini integration, which would let Siri route complex queries through Google\u2019s frontier model rather than Apple\u2019s own smaller on-device systems, has been the most anticipated piece of that puzzle since negotiations between the two companies became public knowledge.
The Deal and Why It Stalled
The delay is not purely technical. The Apple\u2013Google relationship is operating under heightened legal scrutiny. The Department of Justice\u2019s ongoing antitrust case against Google explicitly named Apple\u2019s $18\u2013$20 billion annual default-search deal as a cornerstone of the alleged monopoly. A new multi-year AI agreement layered on top of that arrangement carries obvious sensitivity for both companies \u2014 and likely contributed to the slower-than-expected rollout.
What the March Window Requires
The 9to5Mac analysis centers on Apple\u2019s typical software release cadence. For the Gemini-powered Siri features to land before March 31, Apple would need to seed and release either a new iOS point update \u2014 likely iOS 18.4 or a rapid follow-on \u2014 within days of the analysis being published. That kind of compressed release schedule is atypical but not unprecedented.
A Gemini integration does not require a major iOS version. If the feature is code-complete and toggle-ready, Apple can ship it in a point release on any Tuesday. The question is whether it is actually ready \u2014 and whether both companies have signed off on the user-facing handoff flow and privacy disclosures.
Apple has already established the UX template with the OpenAI integration: a permission prompt informs users before a query leaves the device, and Siri\u2019s interface surfaces which model responded. Applying that same framework to Gemini is straightforward in principle. The friction is almost certainly on the legal and regulatory coordination side, not the engineering side.

Major AI labs now with direct Siri integration (if Gemini ships)
Apple has staked a significant portion of its 2026 product narrative on AI. The company faces pressure on two fronts: from users who expected a more capable Siri by now, and from Wall Street analysts who have begun questioning whether Apple Intelligence is delivering enough differentiation to sustain iPhone upgrade cycles.
Shipping the Gemini integration \u2014 even in a limited early form \u2014 before the end of March would let Apple frame its Q2 earnings call, due in May, around meaningful AI progress. Missing March and pushing into Q2 is not catastrophic, but it extends a narrative that Tim Cook has been eager to put to rest since the WWDC 2024 announcements.
For Google, the stakes are different but equally real. A live Gemini integration inside Siri on 2.2 billion Apple devices would be the largest single distribution event for Gemini to date \u2014 dwarfing its standalone app installs and rivaling the aggregate reach of Google\u2019s own search surface.
