The founder of the electric car company Tesla, Elon Musk, became rich by almost $10 billion in a day. This is evidenced by the data of the Forbes Real-Time rating. Now his fortune is estimated at $99.3 billion.

This is happening against the backdrop of a rise in the price of Tesla shares, which jumped by more than 9 percent to $ 444.47 apiece during trading on Tuesday, November 17. In the Forbes Real-Time ranking, Musk is in fifth place.

Tesla shares rose after the news that in December the company will enter the S&P 500 index-a list of 505 selected companies that are traded on US stock exchanges. S&P Dow Jones Indices believes that the automaker will sharply rise in price, as it will be able to attract money from new large funds. In addition, the new status, experts say, will allow Elon Musk’s company to conduct global expansion in order to increase sales.
