The news: After more than a year of AI stumbles, Apple will reportedly pay Google $1 billion annually to use a custom-built version of Gemini, Google’s flagship AI model, to power a next-generation Siri—marking one of Apple’s boldest AI moves yet, per Bloomberg. The upgraded Siri is set to debut in spring 2026 alongside the iOS 26.4 system update.

Why it’s worth watching: Apple’s AI deal with Google could be a rare admission that it’s fallen behind in the AI race. After leaning on ChatGPT for advanced AI features running on OpenAI’s servers, Apple may now put Google’s Gemini at the heart of its tightly controlled ecosystem.

• For Apple, the addition of Gemini on its Private Cloud Compute will give its products and services parity with the genAI features of Microsoft, Google, and Amazon.
• For Google, the partnership will make Gemini the default AI engine across both Android and iOS, instantly expanding its reach to billions of mobile users worldwide.

Apple and Google are no strangers to partnerships—Google pays Apple around $20 billion annually for default search exclusivity on Safari browsers.

The caveat: We forecast that Siri would surpass Google Assistant (now Gemini) for US users by 2026. However, Apple’s reliance on Google’s AI could weaken its position—handing Google control over the very voice ecosystems where the two compete: mobile, home, and connected car.

What brands should know: A smarter Gemini-infused Siri could redefine how users find information, products, and services—shifting search and ad engagement from text to voice. Apple could use on-device context and privacy controls to serve hyper-personalized suggestions without traditional ads.

For marketers and advertisers, this means adapting quickly to a world where voice agents become the new gatekeepers of attention.

Brands that master conversational visibility—designing experiences optimized for natural language, context, and trust—will own the next frontier of discovery. Everyone else risks becoming invisible in an algorithmic handoff between Apple and Google.
