Nvidia is spending more than ever on Washington lobbying. It still may not be able to stop Congress from limiting its China chip sales now.

Nvidia is increasing its lobbying expenditures in Washington as concerns grow over potential restrictions on its semiconductor exports to China. The company faces mounting pressure from lawmakers who aim to limit advanced technology sales to the Asian nation.

Despite these efforts, Nvidia may be unable to prevent Congress from implementing restrictions. The company's increased lobbying comes at a critical time when U.S.-China technological tensions continue to escalate.
