NVIDIA Shares Jump 5.1% at Market Open, Most Since Nov. 10

NVIDIA shares rose 5.1% at Wednesday's opening bell, marking the stock's largest single-day gain since Nov. 10.

The move came amid renewed investor optimism about the company's AI-related revenue opportunities and strong demand for data-center chips. Trading volume was heavy in the first hour, well above recent averages, as institutional buyers stepped in.

Traders cited continued enthusiasm around AI infrastructure spending and expectations that NVIDIA will maintain leadership in high-performance GPUs. The stock's surge also provided an uplift to other semiconductor names, with sector indexes trading higher in early session activity.

Company spokespeople did not immediately comment. Market participants will watch whether the gain holds through the day and how investors react to upcoming economic and corporate cues.

Correction: An earlier version misstated the percentage gain. The stock rose 5.1%, not 5.5%.
