Alphabet reported on October 28 that third-quarter revenue rose 25% to $127.6 billion, driven by a record performance from Google Cloud, whose revenue climbed 103% to $30.7 billion. Operating income increased 30% and the operating margin reached 31.8%. Yet the quarter also showed how costly the artificial intelligence race has become: the company spent $51.4 billion on property and equipment, more than the $42.3 billion its operations generated in cash. The result has sharpened a question that now hangs over the whole technology sector, which is whether spending at this pace can pay for itself.
The argument for the spending is strong. Google Cloud’s operating income more than tripled from $3.6 billion a year earlier to $11.1 billion, showing that the demand for AI infrastructure is turning into profit and not only revenue. Google Search and other revenue grew 12% to $63.4 billion, and chief executive Sundar Pichai said in the company’s release that search query growth was the highest in five years and that the Gemini app has reached one billion users. Alphabet also said sales of its TPU chip systems contributed meaningfully to growth. If customers keep buying capacity as fast as it can be built, the investment looks less like a gamble than a response to orders. Google Services revenue rose 11% to .3 billion, and Cloud’s share of total revenue climbed to about 24% from roughly 15% a year earlier. The company also said its first-party model APIs now process nearly 32 billion tokens per minute, more than four times a year ago.
The counterargument lies in the cash flow statement. Free cash flow was negative $9.1 billion in the quarter, following negative $5.9 billion in the second quarter, as quarterly capital spending rose from $27.9 billion in the fourth quarter of 2025 to $51.4 billion, an increase of 84%. To fund the gap, Alphabet raised $28.7 billion through senior unsecured notes and sold shares worth $12.4 billion under its at-the-market program. Net income available to shareholders fell to $26.2 billion from $35.0 billion a year earlier, largely because of an $8.2 billion swing in other income and expense, which turned from a gain into a loss. Over the past 12 months Alphabet has spent .8 billion on property and equipment, against free cash flow of only .7 billion.
The implications reach far beyond one company. Alphabet competes with Microsoft and Amazon for the chips, data centers and customers that will define the next decade of computing, and its willingness to borrow and issue stock to keep pace signals that none of them believes it can afford to slow down. For businesses and governments that rely on cloud services, the race promises more capable tools. For investors, it means more of the technology sector’s profits are being committed to infrastructure whose returns are still unproven. Governments are watching too, because access to advanced computing is increasingly treated as a matter of economic strength as well as business competition.
Alphabet’s quarter shows both the reward and the risk of the AI build-out. Growth is accelerating, but the company is now spending more than it earns in cash, and its ability to keep both going will define how this investment cycle is judged.
