Microsoft Tops Apple to Become Most Valuable Public Company

For more than a decade, Apple was the stock market’s undisputed king. It first overtook Exxon Mobil as the world’s most valuable public company in 2011 and held the title almost without interruption.

But a transfer of power has begun.

On Friday, Microsoft surpassed Apple, claiming the crown after its market value surged by more than $1 trillion over the past year. Microsoft finished the day at $2.89 trillion, higher than Apple’s $2.87 trillion, according to Bloomberg.

The change is part of a reordering of the stock market that was set in motion by the advent of generative artificial intelligence. The technology, which can answer questions, create images and write code, has been heralded for its potential to disrupt businesses and create trillions of dollars in economic value.

When Apple replaced Exxon, it ushered in an era of tech supremacy. The values of Apple, Amazon, Facebook, Microsoft and Google dwarfed former market leaders like Walmart, JPMorgan Chase and General Motors.
