AI company Anthropic is matching OpenAI’s aggressive push into the United States public sector, announcing on Tuesday that it will make its Claude models available to all three branches of the federal government for $1 per agency for one year.

The offer goes beyond OpenAI’s recent deal, which applies only to the federal executive branch. Anthropic said it is targeting executive, legislative, and judicial agencies, and will provide both Claude for Enterprise and Claude for Government. The latter supports FedRAMP High workloads, allowing use for sensitive but unclassified federal data.

FedRAMP High is the highest security baseline for civilian agencies under the Federal Risk and Authorization Management Program. Anthropic says Claude meets those standards and can be accessed through AWS, Google Cloud, and Palantir infrastructure, giving agencies flexibility in managing data.

The move follows Anthropic, OpenAI, and Google DeepMind’s addition to the General Services Administration’s list of approved AI vendors. Google has not indicated whether it will match the $1 pricing.

Anthropic framed the offer as an effort to expand AI access across government, from scientific research to constituent services. It said it will provide technical support to integrate Claude into agency workflows.

The company’s technology is already in use at Lawrence Livermore National Laboratory to accelerate research and at the D.C. Department of Health to improve multilingual service delivery.

Anthropic, alongside OpenAI, xAI, and Google, has secured up to $200 million from the Department of Defense for AI projects supporting national security. But the $1 initiative appears aimed at embedding its tools more broadly in public service.

OpenAI currently offers FedRAMP High services via Microsoft’s Azure Government Cloud, but Anthropic’s multi-cloud approach could appeal to agencies seeking greater infrastructure control and operational flexibility.
