Microsoft and Nvidia could both soon hit $4 trillion in market cap. Some analysts believe that there may still be more upside ahead, and that one or both of these companies could soon be worth $5 trillion.

Nvidia made history on Wednesday, becoming the first company in the world to reach a $4 trillion market capitalization. This unprecedented milestone solidifies its position as a dominant force in the global economy and a key player in the artificial intelligence revolution.
