Collaboration on Adversarial Threats and Security Risks Act

This bill creates a legal exemption from antitrust laws for private companies that share information or coordinate actions to protect against specific artificial intelligence security risks. It defines these risks as scenarios where AI could be stolen, weaponized, used to create dangerous weapons, disrupt critical infrastructure, or evade oversight by authorities. To qualify for this protection, companies must act in good faith, use the shared information solely for security purposes, and notify the Department of Justice before any coordinated efforts to delay or limit AI development. The law also ensures that information shared with the government remains confidential and allows the Attorney General to seek court orders if a company fails to prove it acted properly or if the actions ultimately increase security risks.
