Hyperscalers — Cash Flow Is the Rear-View Mirror

The most-quoted number in big tech right now is going the wrong way, fast. Free cash flow — the cash left after operations and capital spending — is compressing across every major hyperscaler, and by some projections the group goes collectively negative within quarters. Before Wednesday's Microsoft and Alphabet reports, it is worth being precise about what that number can and cannot tell you.

The numbers first — the compression is real

Alphabet reported negative free cash flow of $5.9 billion last quarter — its first negative print since the 2004 IPO. Meta's quarterly figure shrank to $784 million, barely positive, with street projections seeing it negative next year. Amazon's trailing twelve months stood at minus $7.6 billion as of June.

The cause is not weakness in the businesses — operating cash flow keeps growing. It is the other line: Morgan Stanley puts combined big-tech AI capital spending near $805 billion this year and over $1 trillion next, and in an October note projected the group's deepest cash burn for 2027. Epoch AI's analysis puts the crossover — capex overtaking operating cash flow in aggregate — in the second half of this year. The invoices for the AI build-out have arrived, and they are larger than the cash the businesses currently throw off.
