Microsoft has begun to scale back on data center spending, according to an analysts’ note, but Wall Street was divided on whether this suggests a change to the company’s artificial-intelligence strategy.

Microsoft Corp. has canceled some leases for US data center capacity, according to TD Cowen, raising broader concerns over whether it’s securing more AI computing capacity than it needs in the long term.

TD Cowen noticed Microsoft doing something strange on Friday. The Open AI partner and tech giant appeared to be cancelling data center leases. According to the market analysts, this is part of a wider pattern. TD Cowen said Microsoft had an “oversupply” problem. It’s another datapoint that points to Big Tech’s nervousness around its big bet on AI.
