Microsoft secured a multi-year, $750 million agreement with AI startup Perplexity.

Perplexity will leverage Microsoft Azure's Foundry service. This service will run large language models from providers including OpenAI, Anthropic, and xAI on Azure's infrastructure.

This partnership reinforces Microsoft's ambition to position Azure as a versatile, multi-model AI platform, moving beyond just an OpenAI channel.

The agreement demonstrates Azure's capability to attract substantial AI workloads. Investors are monitoring how Microsoft's heavy capital expenditures in AI infrastructure translate into contracted revenue and long-term growth.
