U.S. markets were closed Sunday, so policy and technology developments took the spotlight instead of price reaction. Nvidia and AMD reportedly agreed to pay the U.S. government 15% of specified China AI-chip revenue for export licenses, while Nvidia separately denied that its chips contain backdoors or kill switches. Goldman Sachs estimated that U.S. companies had absorbed 64% of tariff costs as of June, and Treasury Secretary Scott Bessent said most outstanding U.S. trade negotiations were expected to be largely completed by the end of October. OpenAI restored GPT-4o after user backlash to GPT-5, while Meta sought $29 billion for its Louisiana data-center expansion.
