Alphabet and Apple are expanding their artificial intelligence partnership. Google Cloud will provide the underlying infrastructure for the next generation of Apple's voice assistant, Siri.

Google technology will also power additional consumer-facing AI features across the Apple device ecosystem.

Alphabet concurrently secured new renewable energy agreements. These deals will supply the company’s growing network of AI-focused data centers.

Investors are evaluating the potential workload and revenue growth for Google Cloud resulting from the Apple alliance. Analysts are also tracking how the new energy agreements will affect long-term infrastructure costs for AI development.
