Nvidia’s market capitalization crossed the $3 trillion threshold this week, officially overtaking Apple to become the world’s second most valuable publicly traded company. The milestone reflects a significant shift in the technology sector, driven by the surging demand for high-end semiconductors essential for generative artificial intelligence. While Nvidia’s stock has seen a meteoric rise of over 140% since the start of the year, some financial analysts have raised questions regarding the sustainability of such rapid growth and the potential for market volatility. Proponents, however, point to the company's near-monopoly on AI data center chips as a foundation for long-term dominance. Apple, which held the title of the world's most valuable company for much of the last decade, continues to face investor scrutiny over its artificial intelligence strategy and slowing hardware sales in key international markets. Microsoft remains the most valuable company globally, though the gap between the top three tech giants continues to narrow as the industry pivots toward AI-centric infrastructure.
