Investors believe that the Democratic Party's control of Congress will cause trouble for Musk's company. SpaceX shares, which hold major government contracts, fell nearly 1.7% in after-hours trading. Tesla's stock price fell by a similar margin. The forecast market shows that the probability of the Democratic Party taking back both houses of the National Assembly hovers around 99%. Other artificial intelligence-related stocks also fell in after-hours trading as markets feared Tuesday's election results might face stricter regulation of data center construction.
