One signal

Congressional leaders are backing tougher controls on advanced AI-chip exports to China, with three proposals included in the Senate version of the must-pass defence bill, Semafor reports. There is not yet an agreement to include them in the final legislation.

The proposals would track chips to deter smuggling, tighten rules on chipmaking equipment and give Congress more oversight of certain chip-sale licences. The debate matters to Nvidia because its advanced chips are central to the dispute, but no new restrictions are in force. Congress has found momentum; it has not yet found a deal.

Discuss: Should Congress put all three chip-control proposals into the defence bill, or could bundling them make agreement less likely?
