Elon Musk Got $36B Richer in One Day

Elon Musk's net worth increased by $36.2 billion Monday, thanks to Tesla's stock surge. That's the largest single-day jump in the history of the Bloomberg Billionaires Index. Musk is now worth $288.6 billion after Tesla saw a 12.7% stock increase due to its deal with the Hertz rental car company. The electric car company is up 45% so far this year, helping Musk, the world's richest man after surpassing Jeff Bezos in January and flipping spots with him several times since, to pull even farther ahead of everyone else on the planet. Musk's 20% ownership in the company is the largest driver of his wealth, Business Insider reports. (More Elon Musk stories.)
