Nvidia shares recorded their largest weekly percentage gain in more than a year, driven by renewed investor confidence in the chipmaker's central role in the global artificial intelligence infrastructure build-out.

The rally was fueled by a fresh wave of Wall Street research notes that reaffirmed the company's dominant market position and highlighted stronger-than-expected capital expenditure guidance from major tech clients.

Goldman Sachs had previously raised its price target for Nvidia to $195 from $180, citing robust demand for AI chips and data center expansion.

This positive sentiment helped offset concerns surrounding a separate US probe into alleged Chinese AI chip smuggling via third countries, which had weighed on the stock earlier in the week.

The stock's performance underscores the market's continued appetite for semiconductor leaders despite geopolitical headwinds.
