Nvidia shares fell 8.9% as semiconductor and AI infrastructure stocks sold off broadly, with Reuters linking the retreat to worries about tighter scrutiny and delayed US data-center projects following Democratic election wins, while an AP report cited financing costs and the possibility of government-imposed construction pauses after the elections; both accounts described investor fears rather than restrictions already enacted against the company. Separately, US committee chairmen Brian Mast, John Moolenaar and Rick Crawford asked Nvidia chief Jensen Huang to appear on November 18 to inform them about his contacts with Megaspeed executive Alice Huang and about Nvidia's security protocols, a request made public yesterday and based on public reports that contains no finding of wrongdoing. Regarding the cloud development platform Brev, media reports from October 30 said a security incident may have exposed customer information and SSH keys, and Nvidia said it had rotated the affected keys and found no evidence of misuse, with the reported unauthorized activity spanning October 4 to 20. A UBS estimate cited by Reuters indicated roughly 30% of the expected additional US data-center capacity in 2028 could be at risk, a scenario rather than secured capacity.
