Alphabet's Cloud Backlog Just Topped $500 Billion. Is Google Cloud About to Overtake Search as the Growth Engine?

Alphabet's Google Cloud division has accumulated a $514 billion backlog and is accelerating revenue growth at 82%, supported by massive $811 billion capital expenditure commitments. While search remains a high-margin cash cow generating $63 billion quarterly revenue, Google Cloud could surpass it as the primary growth engine by next year. Despite near-term free cash flow pressures, analysts project the cloud segment will drive the majority of Alphabet's projected $300 billion free cash flow by 2031, making the stock's current 17x P/E valuation potentially attractive for patient investors.
