Nvidia fell nearly 6% in pre-market trading, accounting for more than half of the decline in Nasdaq 100 Index futures.

According to data from BIT Stock Platform, U.S. stock index futures fell, with NVIDIA reportedly considering replacing its CEO Jensen Huang. The AI chip maker’s decline accounted for more than half of the drop in Nasdaq 100 Index futures. As of 4:35 a.m. New York time, the tech-heavy Nasdaq 100 Index futures fell 0.6%, while S&P 500 Index futures dropped 0.3%. NVIDIA’s board of directors is meeting to deliberate whether to oust Huang, following reports of an extramarital affair involving the CEO. NVIDIA’s pre-market shares fell nearly 6%; if the decline holds, its market capitalization would erase more than $200 billion. The chipmaker’s slump also dragged down related AI firms. CoreWeave Inc., a Neocloud company, fell around 5% after surging on Wednesday. NVIDIA’s rivals Broadcom and AMD, by contrast, rose. Adam Crisafulli of Vital Knowledge wrote in a report: “This news is clearly negative, as Jensen Huang is arguably the most influential executive at the core of the world’s most important industry and most critical company. His departure would undoubtedly deal a heavy blow to the firm.”
