Perplexity AI Signs $750M Cloud Deal with Microsoft
Perplexity AI signs a $750M cloud deal with Microsoft to access AI models via Azure, maintaining AWS as its primary provider.
Perplexity AI Secures Major Cloud Partnership with Microsoft
Perplexity AI, a search startup backed by Nvidia, has entered into a $750 million, three-year cloud agreement with Microsoft. This deal, reported by Bloomberg News, allows Perplexity to leverage a variety of advanced AI models through Azure's Foundry platform without diverting funds from its main cloud provider, Amazon Web Services (AWS).
Strategic Importance of the Deal
The agreement, valued at approximately $750 million over three years, provides Perplexity with expanded computing options on Azure while maintaining its reliance on AWS. Foundry, Microsoft's model aggregation service, hosts competing systems, reinforcing Azure's neutrality despite Microsoft's strong ties with OpenAI.
- Multi-Model Strategy: Perplexity's CEO, Aravind Srinivas, has emphasized the importance of a multi-model approach to enhance the company's answer engine, which provides real-time citations.
- AWS Relationship: Perplexity continues to use AWS as its primary cloud provider, making this deal an addition rather than a replacement.
Perplexity's Growth and Challenges
Founded in 2022, Perplexity has rapidly grown to achieve $100 million in annual recurring revenue (ARR) by late 2025, up from $20 million earlier that year. The company is supported by notable investors, including Nvidia and Jeff Bezos, and raised $500 million in a Series C funding round at a $9 billion valuation.
- User Growth: The company reached 10 million monthly active users by Q4 2025.
- Legal Challenges: Perplexity faces a lawsuit from Amazon over alleged unauthorized access to shopping data.
Competitive Landscape
| Provider | Key AI Clients | Strengths | Market Share (Q4 2025) |
|---|---|---|---|
| Microsoft Azure | Perplexity, OpenAI | Foundry multi-model hub | 25% AI cloud |
| AWS (Amazon) | Anthropic, Stability AI | Cost efficiency | 31% AI cloud |
| Google Cloud | xAI, Adept | TPUs for training | 12% AI cloud |
Perplexity's dual setup with AWS and Microsoft mirrors strategies by other AI firms like Anthropic, aiming to reduce dependency on a single provider.
Market Timing and Broader Context
The deal comes amid soaring AI compute costs, with startups facing challenges due to GPU shortages. Perplexity's strategy counters its AWS dependency following the Amazon lawsuit, signaling a move towards neutrality.
- AI Compute Costs: Costs have increased tenfold year-over-year, impacting startups significantly.
- Industry Trends: Hyperscalers like Microsoft are promoting "model gardens" to capture market share.
Implications for the AI Ecosystem
This partnership accelerates the de-siloing of AI stacks, allowing startups to mix models dynamically. It also pressures AWS to enhance its offerings to remain competitive.
- Investor Impact: Microsoft's stock rose 2% following the announcement, and Perplexity's valuation trajectory continues toward unicorn status.
- Regulatory Risks: Ongoing regulatory probes into cloud monopolies could reshape future terms.
Perplexity's move to Azure underscores a maturing market where flexibility is increasingly valued over allegiance.
