Apple Overtakes Nvidia as World’s Most Valuable Company Amid AI Volatility

Apple reclaimed its title as the world’s most valuable company on Monday, overtaking Nvidia as investor concerns regarding the massive costs of the artificial intelligence buildout triggered a selloff in chip stocks. Shares of Nvidia tumbled 5% to close at a valuation of $4.77 trillion, marking the first time the iPhone maker has held the top spot at market close since April 2025. While Nvidia’s market capitalization briefly touched the $5 trillion milestone in October, its shares have climbed only 4% in 2026, significantly trailing Apple’s 24% year-to-date gain.

The shift in market leadership reflects a broader rotation among investors. While Nvidia’s sales continue to benefit from three years of AI-driven growth, market focus is increasingly shifting toward memory chip providers and data center infrastructure players. Companies such as Micron Technology, SK Hynix, and SanDisk have become focal points for those looking to capitalize on the next phase of the AI boom beyond graphics processing units.

Apple’s resurgence comes ahead of its fiscal third-quarter earnings report scheduled for Thursday. Investors are particularly keen to see the financial impact of a global memory chip shortage, which recently forced Apple to raise prices for Mac and iPad models. Despite these supply chain headwinds, Apple’s stability has offered a refuge for investors spooked by the high-stakes spending requirements of its megacap peers.

Meanwhile, industry experts like Jim Cramer have raised alarms about a potential 'circular financing' bubble. Reports indicate Nvidia is in talks to provide a $250 billion backstop for OpenAI to finance a massive data center campus in Ohio. This follows Nvidia's previous multi-billion dollar investments in customers like Anthropic and neocloud providers, drawing comparisons to the dot-com era where companies essentially financed their own revenue growth.
