Apple has overtaken Nvidia to become the world's most valuable company, ending the chipmaker's long run at the top. According to Reuters, reporters Niket Nishant and Shashwat Chauhan wrote on July 17 that Apple pulled within striking distance and then unseated Nvidia, a milestone CNBC described as the end of the chipmaker's stretch as the market's most valuable name.

The move was tight. According to TradingView, Apple's market capitalization reached about $4.88 trillion as it closed in on the $5 trillion mark, a threshold also noted by 9to5Mac and Moneycontrol. Some outlets, including Free Malaysia Today, reported that Nvidia only briefly dropped below Apple, and Yellow.com cautioned that the slim lead could reverse quickly.

What is driving the shift? Bloomberg framed it as a broader "tech rotation," while Reuters tied it to changing AI bets. According to Moneycontrol, investors are increasingly wagering on Apple's ability to make money from artificial intelligence through its ecosystem, services and hardware — not just the AI infrastructure that powered Nvidia's rise. Yahoo Finance and 24/7 Wall St. noted that Apple spent only a fraction of what rivals poured into AI, yet still took the crown.

There are wrinkles. Gizmodo pointed to Apple's troubled AI efforts, and Moneycontrol reported the company is preparing for a leadership transition. Yahoo Finance also highlighted that Apple is Warren Buffett's biggest bet.

Why it matters: the swap at the top signals that Wall Street may be repricing the AI boom, rewarding companies that turn the technology into consumer products over those selling the picks and shovels.
