Nvidia has become the most valuable company in the world, surpassing Microsoft with a market capitalization of $3.34 trillion. CEO Jensen Huang's firm saw a $3 trillion market cap for the first time in June, overtaking Apple. Nvidia's dominance in the market is fueled by its highly sought-after semiconductors that power AI-related computing tasks. The company's shares have surged over 200% in the past year. Nvidia's CFO, Colette Kress, has played a vital role in the company's success and Wall Street reputation. Kress joined Nvidia in 2013 after an extensive finance career at major tech companies. She focuses on scaling processes and digital solutions to support Nvidia's fast growth. The company reported impressive revenue growth on its latest earnings call. Despite being under scrutiny, Nvidia continues to lead in the AI revolution, rivaled by Microsoft and Apple in the race to $4 trillion market cap.
