President Donald Trump, addressing American voter concerns about rising electricity prices, said his administration had been in talks with Microsoft to ensure that consumers “don’t pick up the tab” for enormous data centers.

In a Truth Social post, he added that while the data centers “are key” to the artificial intelligence boom, the “big Technology Companies who build them must ‘pay their own way.’ ”

He said that Microsoft would make “major changes,” but was not specific. Power prices have risen above the pace of overall inflation, heightening complaints about the cost of energy and other essentials.

The rapid construction of data centers is widely seen as one reason why electricity has become more expensive in the U.S., though it is not the only one. In any case, Democrats have made prices and inflation crucial arguments for the midterm election in November.

On Tuesday, Trump will visit a Ford Motor Co. factory in Michigan and deliver a speech in Detroit intended to promote his tariff and manufacturing policies, and address voter unease about the economy.

Microsoft did not immediately respond to a request for comment on Trump’s post on Monday evening. However, Microsoft’s Vice Chair and President Brad Smith plans to make an announcement at an event in Washington on Tuesday.

“Microsoft has worked with communities to harness the power of technology to build a better future,” the company said in a statement announcing the event, before Trump’s post. “As America approaches its 250th anniversary, the country is entering a new era of opportunity shaped by the power of AI. This moment raises fundamental questions about the future we build together - who benefits from AI, its potential impacts, and who should bear the cost of critical AI infrastructure?”
