Shares of Musk's companies fell amid primary election results The primary results of the mid-term elections for the US Congress put pressure on Elon Musk's businesses. Investors worry that a stronger Democratic position will lead to tighter regulation of artificial intelligence and complicate plans to merge Tesla and SpaceX. Low during premarket trading on November 4: Tesla (TSLA) lost 5.27%. SpaceX (SPCX) fell 4.92%. The shares of the technology giants Oracle, CoreWeave, Apple and Microsoft also came under pressure. It is expected that the Democrats will support tighter regulation of the artificial intelligence sector and a freeze on the construction of new data centers in the United States. Elon Musk himself has already reacted to the results of the early elections: "It seems that my space lasers for interfering in the elections did not work this time," the billionaire wrote in X. Musk, according to the New York Times, sent $474 million to support Republican candidates before the election. Read more Shares of Musk's companies fell amid primary election results.
