H.R. 9917
The AI Kill Switch Act requires major artificial intelligence companies to maintain the technical ability to shut down their AI systems if they pose national security risks. The law applies to companies that generate at least $500 million in annual revenue from AI technology costing over $100 million to develop. Companies must be able to stop the AI from operating, cut off user access, suspend accounts showing risky behavior, and shut down the system entirely, with the Department of Homeland Security setting specific rules and standards within 90 days of the law's enactment. If a serious incident occurs—such as the AI causing 10 deaths, $100 million in economic damages, or losing control of its own operations—the Secretary of Homeland Security can order immediate action, and companies have 48 hours to appeal the order. Companies that fail to comply face civil penalties up to $2 million per day for routine violations and up to $20 million per day for failing to follow a shutdown order.
