Bill Ackman Questions the Fed’s Rate Hike: Can the AI Arms Race Break Down Traditional Inflation Models?
Bill Ackman, founder of Pershing Square, posted on X questioning whether the Fed’s decision to restart rate hikes this month is a mistake. His argument is that the AI arms race is rewriting the traditional logic—“rate hikes suppress demand, thereby lowering inflation.” At the end of the post, he wrote: “I think the Fed may have just made a mistake. Am I right or wrong?” Within two days, the post had already surpassed 1.6 million views, sparking considerable debate online.
Fed Hikes Rates for the First Time in Three Years
According to CNBC, on September 16 the Fed unanimously (12–0) approved a 1-quarter-point rate hike (25 basis points), raising the target range for the federal funds rate to 3.75%–4%. This was the first rate increase since 2023. Officials also hinted that another hike could still happen this year. In the first five meetings this year, the Fed had held steady; the shift this time was driven by stubborn inflation fueled by energy prices.
At the press conference, Chair Kevin Warsh said inflation is “too high and too long,” and the committee has not seen signs that underlying inflation will return to the target quickly enough. The dot plot shows most officials expect rates by year-end to land between 4.1% and 4.4%, higher than prior estimates. As of the 12 months ending in July, U.S. CPI inflation was up 3.4% year over year, still above the Fed’s 2% inflation target.
Ackman’s Argument: Computing Demand Is “Immune” to Interest Rates
Ackman’s reasoning breaks down into three steps. First, rate hikes can curb inflation—provided that higher interest rates suppress demand and investment. Second, in the AI era, this premise may not hold: the rewards for winning a “super-intelligence” competition are almost unlimited, so demand for intelligence and energy will not fall just because interest rates rise; even more, compute demand is “incalculable.” Third, if demand does not cool, rate hikes would instead push interest costs into the prices of all goods and services, driving inflation higher. The Fed would then be forced to hike again, creating a vicious cycle.
It’s worth noting that in its own statement, the Fed also wrote that capital investment is strong and productivity growth is strong. In other words, Ackman is pointing to the same data set the Fed is seeing, but interpreting it in opposite directions.
Counterargument: AI Investment Isn’t the Whole Economy
This claim also has clear weaknesses. First, although AI capital expenditures are enormous, they still represent only a portion of total U.S. demand. Sectors that are more sensitive to interest rates—such as consumer credit, mortgages, and financing for small and medium-sized businesses—are larger in scale. After rate hikes, the costs of credit cards, home equity lines of credit (HELOCs), and floating-rate commercial loans rise immediately, and demand in these areas will still be pressured lower.
Second, the idea that “rate hikes will raise inflation” is close to the view of the Neo-Fisherian school of thought in economics—an unconventional position with limited empirical support.
Third, energy prices are one of the important factors currently pushing inflation higher, meaning this wave of inflation is not driven solely by AI demand.
