Microsoft has officially joined Nvidia in the ultra-elite $4 Trillion club, surpassing Apple Inc. setting pace in the historic market caps.

Microsoft’s valuation hit approximately $4.04 Trillion as its stock climbed 2% to close at $542.07. This rally was fueled by a fresh deal with Open AI, securing a roughly 27% stake in its newly revamped for-profit division –a strategic move aimed at bolstering its AI capacity. Nvidia had recently become the first company to reach a market capitalization of $4 Trillion in July, which was attained by accelerating momentum to the AI industry.

Despite touching the $4 Trillion threshold intraday, Apple’s market cap ended at $3.99 Trillion by close. Strengthened by the iPhone 17 launch and renewed optimism in its services division, Apple regained momentum to compete in the top tier.

The achievement underscores how artificial intelligence and market optimism are reshaping the future of the tech industry, which is no longer about hardware alone. This has been further signaled by Alphabet that hit the $3 Trillion market cap recently, cementing investor optimism to the technology sector.
