The Nasdaq fell 750 points as investors questioned whether the enormous cost of artificial intelligence will pay off. Major technology companies, known as hyperscalers, are pouring money into AI, including data centers and chips. But investors are increasingly concerned that the returns may not be large enough to justify the spending. Those doubts have put cash flow in focus and contributed to market movements. Another source of concern is how AI companies are paying for their expansion: many are relying on debt to finance their data-center and chip investments. Wall Street analysts say that borrowing has made investors more uneasy. The market reaction reflects a broader reassessment of whether the AI boom can generate adequate returns to cover its costs and debt.
