[SpaceX and Tesla stock prices rebound, Musk’s net worth returns to one trillion U.S. dollars] On October 6, the world’s richest man, Elon Musk,’s net worth exceeded one trillion U.S. dollars again after three months. Musk's wealth rose by $65 billion on Monday to $1.04 trillion, according to the Bloomberg Billionaires Index, helped by a rebound in the value of his SpaceX and Tesla shares. Since October, SpaceX’s stock price has risen 13% and Tesla’s stock price has risen 6.7%. SpaceX's stock price soared after its IPO in June, making Musk the world's first trillionaire, but he soon lost that title as investors worried that the company was overvalued and its stock price subsequently fell. As of late July, Musk's wealth has shrunk by more than $600 billion from its peak, a decline greater than the entire net worth of anyone on Bloomberg's list of the world's 500 richest people except himself. The latest round of wealth growth stems from the market's renewed optimism about SpaceX and Tesla. Morgan Stanley analysts said on Monday that SpaceX is one of the investment targets that can capture the huge growth potential in space and artificial intelligence at a lower cost. Shares of the company, which spans space, artificial intelligence and social media businesses, have rebounded 58% from their August lows. In addition, Tesla's third-quarter sales reported last week also came in better than expected. According to the Bloomberg Billionaires Index, Musk's shares in SpaceX and Tesla collectively account for more than 98% of his net worth.
