Nvidia shares closed at $188.08 on November 6, 2025, down -3.65%, marking a sharp decline ahead of its scheduled earnings report on November 7, 2025. The drop follows the White House's November 4 announcement reaffirming a ban on Nvidia's Blackwell AI chips to China, which is expected to impact up to 25% of Nvidia's data center revenue and has heightened investor uncertainty. Analysts remain bullish on Nvidia's long-term AI leadership, but the immediate revenue risk from export controls and high expectations for the upcoming earnings have driven recent volatility. The move is notable given the absence of broader market turmoil, underscoring the company-specific impact of the China ban and earnings anticipation.
