OpenAI Achieves FedRAMP Moderate Authorization for Government Use

OpenAI has secured FedRAMP 20x Moderate authorization for its ChatGPT Enterprise and API Platform, allowing U.S. government entities to utilize its AI solutions while adhering to federal security and privacy regulations. This authorization, revealed in April 2026, follows the introduction of the FedRAMP 20x process by the General Services Administration (GSA) in March 2025, which enhances cloud security validation using Key Security Indicators (KSIs) and automated monitoring. Government agencies can now utilize models like GPT-5.5 in a FedRAMP environment, with plans for Codex Cloud integration. This achievement enables public officials to leverage AI for various functions, including permitting and public health analysis. OpenAI worked closely with the FedRAMP team on KSIs and validation. The authorization is available in the FedRAMP Marketplace, with services accessible directly, through Carahsoft, or other procurement methods. OpenAI aims to enhance feature support via the Significant Change Notification process, bridging the gap between FedRAMP and commercial services.
