Selling artificial intelligence is going well for America's biggest technology companies. Paying for it is the part investors have started to flinch at. Last week Alphabet, Amazon and Intel each reported strong demand for the computing power AI runs on, and within two days of their results the market had marked all three down.

The business works a little like a toll road that has to be built before anyone pays to drive on it. Companies rent computing power through the cloud, the cloud owners spend that money on data centres, chips and the factories that make chips, and right now the spending is running ahead of the rent. The figure that tracks the gap is free cash flow: the cash left over once a company has paid for its buildings and equipment.

## Google's best quarter and its worst day

Alphabet had the most to show. Google Cloud's sales rose 103% in the three months to September, to $30.7 billion, the fastest growth it has recorded, and chief executive Sundar Pichai said the group is now on "a half-trillion dollar revenue run rate".

The bill landed in the same quarter. Alphabet spent about $9.1 billion more on property and equipment than its business generated in cash, and it sold some $12.4 billion of new shares along the way. Its shares then had their steepest one-day fall on record, though Reuters also blamed disappointing search advertising results.

## Amazon's cash swing and Intel's warning

Amazon's version of the gap is wider. Its free cash flow for the 12 months to September turned from a $14.8 billion surplus a year earlier into a $42.4 billion outflow, and the company says the jump in spending behind it mostly reflects AI. In the September quarter alone it raised $48.1 billion of long-term debt. Chief executive Andy Jassy is sticking to the plan: the investment "is working", he said, and "there has never been a trillion dollar revenue business, and we may have two of them in the next 5-10 years."

Intel has no cloud business to point to. It designs chips and makes them in its own factories, and on Thursday finance chief David Zinsner told analysts it does not expect positive cash flow this year as it spends about $20 billion on extra capacity, a bill he expects to rise sharply in 2027\. Chief executive Lip-Bu Tan told the same call he was "disappointed that we were not able to meet strong customer demand in this quarter." Before Friday's open the shares were down 25%, a fall Reuters said would wipe more than $122 billion off Intel's value if it held.

Reuters then added up what the week's worry cost. On its numbers, the Nasdaq-100 index was heading for a loss of about $1 trillion in value on Friday, if early losses held. The worry has not changed the plans: Amazon is still budgeting about $220 billion of capital spending for 2026, and Intel's bill goes up next year.
