US inflation cools, but AI build-out poses latest threat to economic stability

The United States experienced a cooling in its inflation rate during June 2026, with the annual rate falling to 3.5%. This marks the first decline in five months, down from 4.2% in May and below economists' projections of 3.8%. The moderation in prices was primarily driven by reduced costs for gasoline, clothing, and used vehicles. Core inflation, which excludes volatile food and energy prices, remained unchanged for the month and registered a 2.6% increase year-over-year, although it still sits above the Federal Reserve's 2% target.

However, a new economic concern has surfaced with the substantial expansion of artificial intelligence (AI) infrastructure. Massive investments, potentially exceeding $700 billion this year, are being directed towards data centers to power AI technologies. This significant capital outlay is driving up the costs of essential components like memory chips, computer processors, other equipment, and electricity.

Economists anticipate that this surge in AI-related spending will continue to exert upward pressure on inflation, potentially through the end of the year. While not expected to trigger an inflationary spike on the scale seen between 2021 and 2023, the ongoing AI build-out could maintain price levels above the Federal Reserve's desired range. This situation may prompt the central bank to consider raising interest rates later in the year, which would consequently increase borrowing costs for consumers and businesses.
