Elon Musk said reaching quadrillionaire status is “not impossible,” but would require factories on the Moon and Mars to create the needed economic scale. According to BeInCrypto, Musk was responding to a post saying he is about $998.9 trillion short of the $1 quadrillion mark and added that by then “dollars will not be used as currency,” suggesting “mass and energy” instead. The report also cites SpaceX’s $2 trillion IPO debut on Nasdaq and Musk’s projection that SpaceX could reach a $1 trillion revenue target by 2030, after posting $18.7 billion in revenue for 2025.
