Pinterest signs $4B AWS cloud services deal

Pinterest announced on June 4, 2026 that it will commit $4 billion to Amazon Web Services (AMZN) for cloud services through 2031. The multi-year agreement expands the existing collaboration between the two companies and is described as a significant, long-term cloud commitment. It is intended to support Pinterest’s technology roadmap over the next several years.

According to verified information from the companies, Pinterest will pay Amazon Web Services (AMZN) $4 billion for cloud services during this period. The deal formalizes Pinterest’s reliance on AWS as a core infrastructure partner and is framed as a way to secure the computing resources needed for its platform features and advertiser-facing products.

A central element of the agreement is an expanded use of AWS custom processors, including Graviton and Trainium chips, to help scale Pinterest’s artificial intelligence initiatives. Pinterest highlighted these processors as important for achieving compute flexibility and efficiency as its AI workloads grow.

Pinterest said it plans to leverage AWS Trainium to host and run large language models and vision-language models. These models underpin features such as personalized visual search and AI-assisted discovery on the platform, which are key to how users explore content and how advertisers reach audiences.

By increasing its use of AWS custom silicon, Pinterest aims to optimize performance and cost for its AI workloads. The company described the broader hardware options available on AWS as a way to match different AI tasks with appropriate compute resources, supporting both experimentation and large-scale deployment.

Pinterest framed the expanded AWS commitment as a move to accelerate its AI roadmap. The company linked the cloud investment directly to improving infrastructure that supports recommendation systems, search capabilities, and other machine learning driven features used by consumers and advertisers.

Chief Technology Officer Matt Madrigal said the expanded commitment with AWS "gives us the compute flexibility, hardware optionality, and infrastructure efficiency to accelerate our AI vision." This statement underscores management’s view that advanced cloud infrastructure is central to Pinterest’s product development plans.

The announcement of the $4 billion cloud services agreement prompted a positive reaction in financial markets. Following the news, Pinterest shares rose nearly 5%, signaling investor interest in the company’s AI-focused strategy and long-term infrastructure planning.

Amazon shares also moved higher, rising about 1.7% after the deal was made public. News outlets characterized the agreement as a meaningful addition to Amazon Web Services’ long-term customer commitments, reflecting confidence from a major internet platform in AWS’s custom chip offerings and AI capabilities.
