Arm Stocks Rise 5.84% as Agentic AI Tests Its Silicon Expansion

A federal jury found Arm breached its agreement with Qualcomm and interfered with its Meta deal, awarding $1 in damages. Qualcomm seeks a five-year royalty suspension, potentially worth $1.5B, which a judge will decide. The dispute stems from Arm's revocation of Nuvia's license and Qualcomm's use of its technology. Qualcomm also alleges Arm withheld technical support and unfairly competed. Arm denies wrongdoing, arguing Qualcomm wasn't harmed.
