AI data centers are running into a power wall, and that's quietly handing control of the future to a few giant tech companies — bad for small players and ordinary people, good for Big Tech.

• Half of US data center projects are delayed or canceled, not for lack of money but for lack of electricity.
• ChatGPT and similar tools use huge amounts of power, and global demand for data-center electricity is set to soar this decade.
• Solar and wind can't run them around the clock, so Microsoft, Amazon, Google, and Meta are now buying nuclear power directly.
• That power grab squeezes out startups and could raise energy bills for regular households.
• Whoever controls the electricity controls AI, turning a few firms into something close to private governments.

Outlook: Expect the weakest AI players to collapse while Big Tech locks up energy deals and concentrates control over the infrastructure everything else will depend on.
