The Top 50 Companies in 2026

Here are the largest companies by market capitalization as of February 25, 2026:

 

 

As the largest publicly-traded company in the world, Nvidia recently posted a record $68.1 billion in quarterly earnings, up 94% year-over-year.

With OpenAI, Oracle, and Microsoft among its largest customers, a string of strong earnings reports has pushed its valuation close to a $5 trillion market capitalization. Still, investor skepticism has tempered share price gains amid concerns about overvaluation.

Apple, Alphabet, and Microsoft follow, each valued at roughly $3 trillion or more.

Saudi Aramco, one of only two non-U.S. companies in the top 10, ranks seventh with a $1.7 trillion valuation. Weaker oil prices have weighed on its performance, with shares down about 30% from their 2022 peak.

Meanwhile, chip designer Broadcom ranks ninth at nearly $1.6 trillion. In addition to producing custom AI accelerator chips for OpenAI and Meta, it designed Google’s tensor processing units (TPUs).

Today, Broadcom is increasingly emerging as a competitor to Nvidia, alongside companies such as Google (#3) and AMD (#38) as Big Tech prepares to spend $650 billion on AI infrastructure in 2026 alone.
