As of this writing, Nvidia (NVDA) stock is up 1.7% in intraday trading, bringing its market capitalization to $4 trillion. This makes it the most valuable company in the world, and the first company to cross the $4 trillion threshold.

A day after Nvidia set a new record by reaching a $4 trillion market cap, at least three Wall Street analysts issued new reports that rated the stock a buy, according to Bloomberg data. The bulls pointed to Nvidia’s role as the premier chipmaker and the fact that compared to its fundamentals, the stock is still trading at a fair price.

As Nvidia’s market cap has grown, it has become an increasingly large driver of overall market returns. Nvidia, which holds a 6.8% weight in the Morningstar US Large-Mid Index, contributed 2.4 of the 11.4 percentage points gained by the index in the second quarter of 2025. The next-largest contributor, Microsoft, added 1.9 points.
