The news: The smart home wars are shifting from hardware and voice assistants to AI strategy. In back-to-back announcements this week, Google and Amazon introduced the next phase of connected devices with AI front and center.

Both companies are racing to turn smart speakers and displays into AI hubs and ad ecosystems.

Google’s open ecosystem: Google unveiled its Gemini-powered Home and Nest lineup, treating Gemini as a platform rather than a product, per 9to5Google.

• Like Android, it will run across Google’s own devices and third-party hardware, with Walmart already on board. 
• Google plans to upgrade more than 800 million existing devices, ensuring adoption without forcing new purchases. The company is also offering SDKs and partner kits to accelerate OEM participation.

Amazon’s subscription strategy: After several delays, Amazon launched four Echo devices built for Alexa+, a next-generation AI assistant bundled with Prime subscriptions or $19.99 per month without Prime. 

• Backed by custom silicon and Omnisense sensors, the devices deliver proactive “ambient AI”—from reminders triggered by presence detection to alerts when a door is left open. 
• Amazon also plans to launch an Alexa+ Store, integrating services, subscriptions, and commerce into its ecosystem.

Smart home consumers are a captive audience: 66% of Gen Zers and 58% of millennials consider AI assistants on smart devices at least somewhat valuable, compared with 45% of baby boomers, per a YouGov survey. 

The addition of AI promises more engagement—early Alexa+ users are already doubling time spent compared with before AI was added.

Our take: AI’s infusion into the smart home paves the way for ads and subscriptions, especially with millions of existing smart home devices. It also opens new avenues for brands to capitalize on conversational or ambient experiences.

Marketers should start testing conversational ads, commerce integrations, and context-driven experiences on both platforms as usage scales and the next dominant household gatekeeper takes shape.
