Sanders and Casar Unveil Bill to Outlaw Superintelligent AI in the U.S.

U.S. Senators Bernie Sanders and Greg Casar have introduced legislation that would effectively ban the development and deployment of superintelligent AI systems within the United States. The bill represents one of the most aggressive AI regulatory proposals to date at the federal level, going beyond capability thresholds or licensing requirements to an outright prohibition on a class of systems. While the bill's prospects for passage remain uncertain, its introduction signals growing legislative pressure on frontier AI labs and could influence future regulatory frameworks even if it does not pass in its current form. For developers and companies building toward advanced AI capabilities, this is a policy signal worth monitoring — particularly as it may prompt responses from T1 labs and industry groups. The bill's definition of 'superintelligent AI' will be a critical detail to watch as the legislative text is analyzed.
