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 stock trades at $166.46 as CEO Jensen Huang sells $36M in shares and overtakes Warren Buffett in net worth amid AI-led rally.

Tech's Big Three (Nvidia, Microsoft, and Apple) are now worth $10.87 trillion, triple their value 5 years ago. Are they at their peak or still growing?

AI has propelled the two companies toward an exclusive club, but Microsoft’s path forward is more complicated.

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.

Nvidia and other companies benefiting from the AI boom have been a major reason the S&P 500 has climbed to record after record recently.
