After Microsoft’s $4 trillion milestone, who will be next to join the club?

Microsoft became the second company to pass a $4 trillion market cap mark after a blowout earnings release on Wednesday afternoon. That release showed quarterly revenue up 18% year-over-year, and net income up 24%, which resulted in Microsoft shares increasing more than 4% on Thursday, bringing the company’s overall value past $4 trillion.

Microsoft follows Nvidia as the only two companies to have breached $4 trillion, and Microsoft’s stock has more than doubled over the past three years. It’s also roughly six years after Microsoft passed the $1 trillion mark.

Other companies are also hot on its heels. Here are five others that could become the next $4 trillion companies.

Apple

Apple will report earnings on Thursday after the bell, which could have an impact on its overall value. As it stands, the company has a market cap of roughly $3.1 trillion—still a ways off from $4 trillion—but is the third-largest public firm in the world, measured by market cap. It was the first company to cross the 1 trillion, $2 trillion, and $3 trillion market cap marks, too, and shares are currently trading at around $210.

Notably, shares are down almost 15% year to date, but have nearly doubled in value over the past five years.

Amazon

Amazon is the fourth-largest public company in the world by market cap, with an overall value of around $2.5 trillion. Like Apple, Amazon will report earnings after the bell on Thursday, which could increase or decrease its value. The company does have a lot of ground to make up on Microsoft and Nvidia to reach $4 trillion, which would require some significant movement in its share price, which is currently trading at more than $230.

Alphabet

Alphabet, Google’s parent company, is the only other public company worth more than $2 trillion as of writing, with a market cap of around $2.33 trillion. Like Amazon, that means there’s quite a lot of work to do to get to $4 trillion. Alphabet’s shares were trading for around $192 on Thursday afternoon, which was an intraday decline of 2%. Alphabet’s most recent earnings report came out on July 23.

Meta

The only other company within spitting distance of $4 trillion is Meta, which, as of writing, has a market cap of around $2 trillion. Following its latest earnings release on Wednesday, Meta shares increased 12%, with revenues up 22% year-over-year, and net income up 36%.
