Perplexity reportedly agreed to spend $750 million on Microsoft Azure over three years, using Microsoft Foundry to access AI models from OpenAI, Anthropic and xAI. But the deal is not a confirmed break with Amazon Web Services: Perplexity has said AWS remains its preferred cloud infrastructure provider and that it had not shifted spending away from AWS.
The distinction matters. The agreement points to a bigger Azure relationship and broader model access, not a verified migration—and its timing alongside Amazon’s lawsuit does not show that the lawsuit caused the deal.
What the reported agreement covers
Bloomberg reported that Perplexity signed a three-year, $750 million agreement to use Microsoft Azure. The arrangement reportedly makes Microsoft Foundry the company’s primary platform for sourcing AI models, including systems from OpenAI, Anthropic and xAI. Bloomberg’s report and a Reuters account carried by Yahoo Finance describe the terms as reported information, rather than details published in a contract announcement by Perplexity or Microsoft.

The public reporting does not specify an annual spending schedule, minimum usage, or whether the total includes compute, model inference, storage, support, credits or reserved capacity. It also does not disclose which workloads or products are covered, whether Azure receives exclusivity or preferred-provider rights, or how the agreement can change if demand shifts.

Foundry’s role also needs to be kept distinct from the models it offers. Microsoft supplies the Azure infrastructure and Foundry platform; OpenAI, Anthropic and xAI are separate model providers. Perplexity, in turn, builds its own search, answer-generation, browsing and agent products. Accessing another company’s model through Foundry does not mean Microsoft owns that model.
Is Perplexity leaving AWS?
Not according to Perplexity’s reported public statement. The company said AWS remained its “preferred cloud infrastructure provider” and that it had not shifted spending away from AWS. It also indicated that it expected to announce further AWS partnership expansions, according to the Reuters report.

These terms describe different things:
- Preferred infrastructure provider describes a favored or principal cloud relationship; it does not necessarily mean exclusivity.
- Model-sourcing platform is a route for accessing and managing AI models. That can be Microsoft Foundry even when AWS remains an important cloud provider.
- Cloud-spend commitment is a commercial obligation reported over a period of time. It does not, by itself, identify which existing workloads are moving.
- Workload migration means shifting particular production systems from one provider to another. The reported Azure agreement does not establish that this has happened.
So “Perplexity switches from AWS to Azure” goes beyond what the reporting supports. A substantial Azure commitment can coexist with a preferred AWS relationship, and the available sources do not establish Azure exclusivity or an AWS spending reduction.
Why add Azure and Foundry?
The deal’s reported structure creates several plausible strategic benefits, though the sources do not confirm Perplexity’s motives. A platform offering models from multiple providers could make it easier to choose systems for different tasks. Additional Azure capacity could diversify access to computing resources. Multiple cloud relationships can also give a company more negotiating options and alternatives when availability, price or product needs change.
Microsoft may gain from acting as an intermediary in that arrangement. A customer can use Azure infrastructure and Foundry to work with models developed by other companies, giving Microsoft a role in the platform and infrastructure layers without developing every model itself. Microsoft’s enterprise ecosystem may also be useful if Perplexity sells more products to business customers, although the reported deal does not disclose how much it covers enterprise versus consumer products.
Those potential advantages come with trade-offs. Running across clouds can add work in engineering, security, monitoring, compliance and data transfer. Model pricing, latency, availability and behavior can vary by provider. A large multiyear commitment may limit flexibility or create cost exposure if usage or revenue grows more slowly than expected. It is not known whether Perplexity’s agreement guarantees particular GPU capacity, how it prices usage internally, or what happens if committed spend exceeds demand.

How the Amazon lawsuit fits in
Amazon sued Perplexity in the U.S. District Court for the Northern District of California on November 4, 2025. The dispute concerns Perplexity’s Comet browser and its AI agents, which can interact with websites and carry out actions for users. Amazon’s complaint alleges that the agents accessed protected Amazon systems and customer data and obscured or failed to identify automated activity. Those are allegations, not final findings. The federal case docket and Amazon’s complaint describe the case.

The order imposes interim restrictions concerning access to Amazon’s protected computer systems and the handling or destruction of Amazon data obtained through AI agents. A preliminary injunction is not a final ruling on all claims or a determination that Amazon will ultimately prevail. Perplexity appealed; the Ninth Circuit docket lists case 26-1444. The available materials do not establish a later final decision on the merits. Read the district court’s order and check the Ninth Circuit docket for case records.
The lawsuit is relevant context, but it is separate from the Azure contract. It concerns how Comet agents interact with Amazon systems, not whether Perplexity may use Azure. The timing may make the Microsoft agreement strategically notable, and a cloud relationship outside AWS could provide flexibility. But the available reporting does not establish that the lawsuit caused Perplexity to sign the deal. Nor would hosting software on Azure automatically resolve the legal dispute or remove any court-ordered restrictions on how its agents access Amazon.
What the deal signals about AI cloud competition
The reported agreement illustrates how AI businesses can assemble services from multiple layers: cloud infrastructure, model platforms, models from different developers, and their own user-facing products. A company may seek model choice or added capacity without moving every workload to a new cloud. For Microsoft, a platform that connects Azure customers with models from other firms could be valuable even when Microsoft did not develop those models.
For customers and investors, the $750 million figure is a signal of the scale of the reported commercial commitment, not a transparent price benchmark. The contract terms, workloads and payment mechanics are not public. The figure therefore cannot show what Azure access would cost another business, how much capacity Perplexity will use, or whether the spending will be economical for either company.

Until those details are disclosed, the clearest description is a major reported Azure expansion and model-access agreement alongside an AWS relationship Perplexity says remains preferred.
