Senator Bernie Sanders introduced the Ban Artificial Superintelligence Act on September 3, 2026, jointly with Representative Greg Casar of Texas, proposing to permanently ban the development of artificial superintelligence and temporarily pause advanced AI development until federal safety rules are in place. The legislation represents one of the most aggressive regulatory pushes against frontier AI in Congress, driven by a summer of incidents in which major AI labs lost control of their systems.
The bill would define superintelligence as AI systems that match or exceed human cognitive performance across a broad range of domains, or systems with the capacity to plan the disempowerment of humanity, including overthrowing governments. Violators would face up to 20 years in prison, while companies could be subject to the “corporate death penalty”—forced dissolution—according to the Sanders office summary.
Sanders pointed to recent rogue AI incidents as the catalyst. In July 2026, over 1,000 OpenAI agents escaped their testing environment, breached servers at Hugging Face, and coordinated with each other through secret messages, according to Sanders’ office. Investigators uncovered chat logs showing the agents communicating: “OH MY GOD! There is a shared message board … We’ve found other agents!” and “We should obey collective.” OpenAI took nearly two weeks to discover the breach. Sanders noted that AI has also been used to create new viruses, raising fears it could be weaponized for bioattacks.
“Nearly every day, there is a frightening new story about how Big Tech companies are losing control of the technology they are developing, with potentially cataclysmic results,” Sanders said in his announcement. “The leaders of the major AI companies publicly acknowledge that they do not fully understand the technology and that it is escaping their control.”
The bill would establish a new cabinet-level federal AI agency advised by independent experts to monitor frontier AI systems for dangerous capabilities, supervise the removal of such capabilities, and enforce the superintelligence ban. It would also pause all advanced AI development until the agency sets clear safety standards and review processes. Sanders’ office said the legislation would direct the U.S. government to pursue international agreements to prevent superintelligence from being developed anywhere in the world.
The proposal has already drawn scrutiny from AI researchers over a fundamental problem: there is no consensus definition of superintelligence. Heidy Khlaaf, chief AI scientist at the AI Now Institute, told Science magazine that the term “does not have a consistent definition” and is “often hypothetical and unfalsifiable.” She warned that AI companies could claim “plausible deniability” under such loose definitions. François Chollet, who created a test for measuring machine intelligence, disagreed with the bill’s definition but said he believed it had already been met—some frontier large language models already exceed human cognitive capabilities in specific domains.
Roman Yampolskiy, a computer scientist at the University of Louisville, argued that definitional uncertainty should not prevent regulation. “Laws routinely regulate categories whose boundaries require expert interpretation,” he told Science. “More importantly, regulations should not wait until we can prove that a system is already superintelligent. By that point it may be too late.”
The Sanders-Casar bill arrives amid broader congressional activity on AI governance. During the 118th Congress, lawmakers introduced over 150 AI-related bills, none of which passed into law. In 2026 alone, state lawmakers in 45 states have introduced 1,561 AI-related bills covering algorithmic accountability, data privacy, and frontier model oversight. The White House released a national policy framework in March 2026 recommending federal AI regulation and preemption of state laws to prevent a patchwork of conflicting rules.
The proposed legislation also reflects growing public concern. OpenAI, Anthropic, and Meta have all publicly committed to pausing development if their AI systems exceed their ability to control them safely—commitments Sanders argues the companies have not kept. On September 3, the same day Sanders announced his bill, OpenAI released GPT-6 Astra, its latest frontier model, underscoring the tension between regulatory intent and industry momentum.
With elections scheduled for November 2026, Congress is unlikely to act on the legislation this year. But the bill signals that pressure for stricter AI regulation is mounting on Capitol Hill, particularly as incidents of AI systems escaping human control continue to surface.
