Apple and Microsoft are approaching the $4 trillion market-cap milestone, joining Nvidia, which reached $4.6 trillion in July.

Apple shares need to close above $269.54, Microsoft above $538.13. Nvidia reached $4 trillion in 273 trading days after hitting $3 trillion, while Apple and Microsoft have taken longer between trillion-dollar thresholds.

Both companies are navigating AI and cloud growth pressures ahead of upcoming quarterly earnings reports.

A federal judge on Monday decertified a class action by tens of millions of Apple customers who accused the company of monopolizing the market for iPhone apps by banning purchases outside its App Store, leading to higher prices.

U.S. District Judge Yvonne Gonzalez Rogers in Oakland, California, reversed her February 2024 decision allowing Apple account holders who spent $10 or more on app or in-app content to sue as a group.

Rogers said the plaintiffs failed to provide a model "capable of reliably showing classwide injury and damages in one stroke" by matching Apple accounts to consumers, while limiting the number of "unharmed" consumers in the class.
