SpaceX Is Spending $18.4 Billion a Quarter. Should Investors Be Worried?

SpaceX's quarterly capital expenditures of $18.4 billion raise questions about investor returns, but the spending is primarily directed toward AI infrastructure ($15.8 billion) and other growth initiatives. With 247% year-over-year AI revenue growth and payback periods under a year, the investments appear justified for now. However, investors should monitor whether SpaceX can maintain attractive returns as competition in data center infrastructure intensifies and the company's $1.9 trillion valuation leaves little room for mediocre returns.
