SpaceX has reportedly joined a group of stocks with a market valuation of over $2 trillion, although its membership in this group may be uncertain as it briefly dropped out this week. The company is part of a larger group that includes other major tech stocks, but its position in this group and its valuation are being questioned. Other stocks, including Nvidia, Alphabet, Apple, Microsoft, Amazon, and Taiwan Semiconductor, are also valued at over $2 trillion.
