The letters C-E-O conjure up images of private jets, massive expense accounts and country club business deals hashed out over golf and caviar. For the richest of the rich corporate bosses, however, that’s all child’s play. The titans of the business world who inhabit the tippy top of the pyramid are wealthy beyond the wildest reaches of the imagination.

Mark Zuckerberg

Before Mark Zuckerberg, rich guys had a look, but the controversial Facebook founder refused to lose the dorm room jeans and hoodie even once the real money started rolling in — and it did. The godfather of social media made his first million when he was 22 years old. Just one year later, Zuckerberg became the youngest self-made billionaire in history at the age of 23.

Satya Nadella

Microsoft was reborn under the stewardship of Satya Nadella, who became CEO in 2014.

Elon Musk

The only other superstar CEO in Bezos’ universe is Elon Musk, the wily Tesla boss with the world’s No. 2 net worth, as of Jan. 26, according to Forbes. No one else is close to the dueling duo, with the world’s third-richest individual looking up from tens of billions of dollars behind. Musk spent much of the holiday season nibbling at Bezos’ heels, with the former briefly eclipsing the latter before Bezos reclaimed his title as the world’s cash king. Musk’s rise has been incredible to watch. His net worth grew by an astonishing $150 billion in the short, chaotic time between March 2020, when the virus arrived, and the turn of the new year.
