Online reported that on Wednesday local time, Elon Musk reached another major milestone, becoming the world's first millionaire to reach US$500 billion. According to real-time data from the Forbes Billionaires List, as of 3:30 pm EST, the world's richest man's worth has reached US$500 billion. In December last year, Musk became the first millionaire to be worth more than $400 billion. Now his worth is $150 billion higher than Larry Ellison, who ranks second, and he is already halfway away from becoming the world's first trillionaire. Tesla shares rose nearly 4% on Wednesday, adding about $9.3 billion to Musk's wealth as investors continue to be bullish on Musk's refocusing focus on Tesla affairs. As Tesla's market value rebounds to within 10% of its all-time high set in December last year, Musk's 12% stake in Tesla is now worth $191 billion. (Jin Shi)
