Nvidia CEO Jensen Huang said AI developers should not release systems that fail safety standards and that laboratories unable to contain potentially harmful experiments should shut down, although he clarified that he was not calling for immediate closures. In an interview on The Ezra Klein Show, Huang opposed collective efforts to slow frontier-model development and exemptions from antitrust or product-liability rules, while supporting application-specific regulation and outside safety testing. He said more intensive testing could increase model-development computing requirements tenfold, potentially boosting demand for Nvidia semiconductors. Senator Bernie Sanders cited Huang's remarks in support of a bill banning artificial superintelligence. The discussion followed reported safety incidents involving OpenAI and Google Gemini, calls from OpenAI CEO Sam Altman and Anthropic chief Dario Amodei for international safety protocols, and Microsoft President Brad Smith's support for an AI kill switch. Nvidia shares closed 1.47% lower at $225.51 on Wednesday, slipped 0.2% in extended trading, and were later reported down roughly 1% to 1.5% in early Thursday trading.
