Amazon Web Services announced a plan to invest up to $50 billion to expand cloud infrastructure dedicated to artificial intelligence and high-performance computing for U.S. government agencies. The company said the multi-year buildout will begin in 2026.

AWS stated that the project will increase capacity across AWS Top Secret, AWS Secret, and AWS GovCloud (US). The expansion is expected to add nearly 1.3 gigawatts of advanced compute power for classified and unclassified government workloads.

Amazon said federal agencies will gain wider access to AI tools, including Amazon SageMaker, Amazon Bedrock, Amazon Nova, Anthropic Claude, leading open-weights models, AWS Trainium chips, and NVIDIA AI systems. The company said the infrastructure will support model training, simulation, and mission operations in secure environments.

According to Amazon, the investment will allow agencies to apply AI to large-scale modeling and simulation. The company said this will enable autonomous experimental steering and real-time feedback loops, reducing processes that previously required weeks to only hours.

AWS said the expanded environment will support uses such as analyzing global security data and automating threat detection across satellite imagery and sensor feeds. The company also cited expected gains in research fields that include energy, healthcare, cybersecurity, and autonomous systems.

AWS CEO Matt Garman said the investment will change how federal agencies use supercomputing. He said the added capacity will give agencies broader access to advanced AI systems that can speed work in areas ranging from cybersecurity to drug discovery. He said the initiative is meant to remove technology barriers that have slowed government adoption.

Amazon described the move as aligned with the Administration’s AI Action Plan and part of a shift toward AI-driven research workflows. The company highlighted natural-language interfaces and AI agents as emerging tools for exploring complex scientific and technical problems.

The announcement builds on earlier AWS government cloud programs launched over the past decade, including AWS GovCloud in 2011 and air-gapped services for classified workloads in 2014. Amazon said more than 11,000 government customers currently use AWS and that the new investment will support national security, scientific research, and the U.S. industrial base.
