Apple finished Monday as the world's most valuable company, moving ahead of Nvidia by the close of trading. The change put the iPhone maker back on top for the first time since April 2025.

The move ended Nvidia's recent run in the top spot. Nvidia had been the most valuable company since June 2025, when it overtook Microsoft, showing how quickly leadership among the biggest U.S. tech companies can shift.

The latest ranking change highlights the intense investor focus on a small group of mega-cap technology names. Apple remains closely tied to its iPhone business, while Nvidia has become a central company in the artificial intelligence boom because of its AI chips.

With Apple now ahead at market close, the race for the top valuation remains one of the most watched storylines on Wall Street. The standings have changed several times in recent months, reflecting sharp market swings around major technology stocks.
