Tesla's Elon Musk Overtakes Bezos as World's Wealthiest Person

Elon Musk has overtaken Amazon . Messrs. Musk and Bezos, both founders of rocket companies, have clashed over issues such as Amazon's power over book publishing and Mr. Musk's interest in colonizing the planet Mars. Amazon last year bought a self-driving-car startup that would compete with Tesla. Mr. Musk's net worth totaled around $195 billion Thursday, up from roughly $30 billion a year ago and topping Mr. Bezos's wealth by about $10 billion, according to the Bloomberg Billionaires Index. The value of Tesla's shares rose almost 8% Thursday, enough for Mr. Musk to overtake Mr. Bezos in the wealth ranking.
