Saudi Aramco

Aramco is the one non-tech name in the top six, and it earns its spot the old-fashioned way: pumping millions of barrels of oil a day at some of the lowest extraction costs anywhere in the world. That cost advantage is what lets Aramco keep paying an enormous dividend -- tens of billions of dollars a year -- which in turn funds a meaningful share of Saudi Arabia's Vision 2030 diversification push. Valued at roughly $1.65 trillion, it's a reminder that the AI boom hasn't rewritten every rule of global finance.
