Alphabet reported $119.8 billion in Q2 revenue with Google Cloud surging 82% year-over-year. Free cash flow swung negative $5.9 billion. Microsoft's operating cash flow hit $35.8 billion last quarter, yet capex including finance leases climbed to $37.5 billion, pushing the company into negative FCF territory. Tesla's adjusted earnings landed at $0.33 per share while capex jumped 142% to $5.8 billion, leaving free cash flow at roughly negative $1.1 billion.

The pattern repeats across the industry. Earnings look stellar on earnings calls. Stock opens higher. Then the cash flow statement lands and mood shifts. This gap between profit and cash has always existed, but the AI buildout is making it impossible to ignore. According to Reuters, hyperscalers are on track by 2027 to spend more on capex than they generate in free cash flow, with 2026 consensus estimates near $730 billion in capex against roughly $1.57 of capital spending for every $1 of extra operating cash flow.

Why reported profits and actual cash diverge

Three mechanics drive the split. Timing is the first: you can book revenue today and collect payment months later, or pay suppliers upfront before shipping anything. Classification comes second. Expense a cost and it hits earnings immediately. Capitalize it as an asset and you spread the charge across multiple years. Financing rounds out the trio, with leases, stock-based compensation, and working capital swings all creating friction between the number on the income statement and the cash moving through the bank account.

None of this is new accounting trickery. It's the messy reality of growth hitting the books. When you sell more, hire faster, and build out infrastructure for AI chips and cloud capacity, the bills land before the revenue does. Revenue recognition under current standards doesn't wait for payment. Capex doesn't get expensed upfront. Working capital balloons as inventory and receivables swell to support higher sales. The company looks profitable on paper while cash burns.

Investors tracking this should watch operating cash flow minus capex first. Then drill into working capital swings, lease obligations buried in finance line items, stock-based compensation, and any costs reclassified from expense to asset on the balance sheet. The AI spending cycle has turned what used to be a footnote into the main story.
