Perplexity signs a $750m deal with Microsoft for long-term cloud and compute resources, marking a shift in AI competition.

Context

AI startup Perplexity has agreed to a $750 million, three‑year deal with Microsoft to use its Azure cloud services to operate a suite of advanced AI models, according to persons familiar with the matter. Under the arrangement—part of Microsoft’s Foundry program—Perplexity will deploy models from major developers including OpenAI, Anthropic, and xAI on Azure’s infrastructure. Although Perplexity confirmed the partnership includes access to “frontier models from X, OpenAI, and Anthropic,” it also said this arrangement does not replace its existing spending with Amazon Web Services (AWS), which remains its primary cloud provider.

Pending intelligence enrichment.

Analysis

This cloud deal comes amid broader tensions in Perplexity’s infrastructure relationships: in 2025 Amazon sued the startup over its “agentic” shopping feature, alleging the AI tool accessed customer accounts and mimicked human browsing behavior—a controversy that underscores growing legal and operational challenges in agent‑based AI services.

Infrastructure is costly, complex, and crucial to scaling deployments reliably, making strategic cloud partnerships a pivotal element of business planning for AI firms. Locking in multi‑year cloud arrangements allows startups to negotiate capacity, pricing, and specialized tooling—but it also raises questions about dependency on specific providers and the risks that accompany such concentration. While diversifying compute sources can provide redundancy, it may also limit flexibility if strategic priorities or cost structures change over time.

Key Points

Perplexity has struck a $750 million, multi-year cloud infrastructure deal with Microsoft to run advanced AI models via Azure.
The pact demonstrates how AI developers are focusing on long‑term compute commitments and diversified cloud partnerships amid rising infrastructure pressures.
