Billionaire Elon Musk, the world’s richest person, is nearly halfway to becoming the planet’s first trillionaire, Forbes magazine reported Wednesday. The 54-year-old’s net worth hit $500.1 billion Wednesday before dipping back to $499.1 billion, the publication’s “Real-Time Billionaires” tracker reported. Ranked after him are Oracle CEO Larry Ellison with a net worth of $350.7 billion, followed by Meta CEO Mark Zuckerberg with a net worth of $245.8 billion on the Forbes list. After graduating from the University of Pennsylvania and dropping out of Stanford University, Musk banked his first millions when he sold an online publishing software company to US computer maker Compaq for more than $300 million in 1999. His next company eventually merged with PayPal, and after leaving that venture, the South African-born tech entrepreneur founded space rocket company SpaceX in 2002 and became the chairman of electric carmaker Tesla in 2004.
