Mark Zuckerberg | $135 Billion

Mark Zuckerberg is one of the world’s wealthiest people and the youngest individual in the top 20 list. His net worth now sits at $1.35 billion as of 2021. Impressive for a 36-year-old man, isn’t it?

Initially, Facebook was solely available to Harvard students. The site’s popularity began to rise, and by 2010, it had reached 500 million members worldwide. The staff grew dramatically once the office moved from Harvard to California. Facebook is becoming the go-to place for people to keep up with their friends’ lives, as well as one of the most important news sources on the internet. The majority of Zuckerberg’s wealth comes from his 13% ownership of Facebook. While Facebook spent almost $25 million on him alone in 2020, his take-home compensation is only $1. Even with such investment money, Zuckerberg and his family live a low-key existence.
