Fed official Goolsbee warns that the AI spending boom is now pushing broad inflation.
Austan Goolsbee, president of the Federal Reserve Bank of Chicago, told Semafor in an interview published October 12 that inflation tied to the AI buildout is "jumping out of its lane." He was not referring to chip stocks or cloud computing bills. He meant land, electricity, water, construction labor, and electrical components, the unglamorous inputs that have little to do with training a model and everything to do with pouring concrete and running power lines to the data centers that do.
"Prices are going up in spaces that are not just components in data centers and the directly adjacent industries," Goolsbee said, according to Semafor's Compound Interest. "I'm getting increasingly nervous that that's just straight, old-fashioned overheating demand." He pointed to businesses outside the tech sector that are now competing with hyperscalers for electricians, for land near power substations, and for the transformers and switchgear that take a year or more to deliver. That is no longer a supply chain story. It is a demand story, and demand-driven inflation is exactly the kind the Fed has the least patience for.
Many analysts have called the AI capital expenditure boom a bubble. Michael Burry shorted Nvidia and Palantir on that bet. Goolsbee is not a short-seller, however, and he is not talking about whether Nvidia's stock is overvalued. He is a voting member of the Federal Open Market Committee, as of 2027. What he describes is closer to a macroeconomic constraint: capital spending so large and so concentrated that it is bidding up the price of ordinary inputs across the whole economy, much as a war or a housing boom might.
That reframes the "AI isn't a bubble, it's a buildout" argument that chip executives and cloud providers have used all year to dismiss bubble talk. Even if every dollar spent on data centers eventually pays for itself through productivity gains, as AI boosters insist, Goolsbee's point is that getting there runs through years of tighter capacity in construction, power, and skilled trades. The Fed cares about that path, not just the destination.
His comments followed a Chicago Fed appearance on October 13, where he went further. He told reporters he is watching for "old-fashioned overheating demand" and warned that a bubble unwind, if debt in AI financing is high enough, "can get ugly." In one breath, Goolsbee connected two separate risks: inflation now and a disorderly correction later, if the financing underneath the buildout proves as stretched as some credit analysts have warned. Those analysts include observers tracking CoreWeave's widening credit default swap spreads this month.
**The timing with inflation data makes it harder to dismiss**
Goolsbee's remarks landed just before the Bureau of Labor Statistics released its September CPI report on October 14. Forecasters had expected that report to show headline inflation climbing toward 3.6% to 3.7% year over year, up from 3.4% in August. The Fed had raised its benchmark rate a quarter point in September, to a range of 3.75% to 4.00%, its first hike in three years after three cuts in 2025. Markets had been pricing in a pause at the October 27-28 meeting and another quarter-point hike in December.
A Fed president publicly worrying about broad-based overheating, delivered the same week as a hot inflation reading, is not background noise. It is a voting member signaling something real. The committee's room to stay patient on rates may be shrinking, and AI capital spending, the force behind so many growth narratives on Wall Street this year, is now part of the reason why.
Goolsbee called a future AI payoff "lovely," but said the Fed must still watch overheating now.
