Nvidia Becomes First Company to Reach $4 Trillion Value

U.S.-based chipmaker Nvidia reached a major milestone by becoming the first publicly traded company to cross a $4 trillion market value. This shows how important Nvidia and the technology sector have become to the overall stock market. The company’s fast growth has also made it a major player in top market indexes.

Nvidia’s Rapid Rise

Nvidia’s stock has grown quickly in recent years. Since October 2022, its share price has jumped by about 1,350%, and it is up 22% in 2025 alone, compared to just 6% for the S&P 500. The company reached the $4 trillion milestone just over a year after it first hit $3 trillion, showing its strong and steady growth.

Impact on the Stock Market

Because of its high value, Nvidia now holds the biggest share in the S&P 500 index (about 7.5%), which is a key measure of the U.S. stock market. It also has a large share in other major indexes like the Invesco QQQ ETF and the Philadelphia Semiconductor Index. This gives Nvidia great influence on how these indexes perform.

However, its role is smaller in the Dow Jones Industrial Average, which is based on stock prices rather than total value.

Tech Sector’s Dominance

Nvidia is not alone at the top. Other tech companies like Microsoft (around $3.7 trillion) and Apple ($3.1 trillion) are close behind. Together with Amazon, Alphabet, Meta, and Broadcom, the top seven tech companies now make up about one-third of the S&P 500. The technology sector as a whole is now the largest part of the U.S. stock market, nearly matching its size during the dot-com boom in 2000.
