Federal Reserve Chair Kevin Warsh devoted much of his Jackson Hole address to artificial intelligence, calling the current pace of AI development a "turning point in history" that has outpaced even the most optimistic forecasts from a few years ago. He said corporate capital expenditure is growing at its fastest rate since 2021, up roughly 9% over the past four quarters, with more than half of that tied to AI buildout. Warsh said he will focus on the "second-order change" in AI capex growth — whether the pace continues to accelerate. He also noted that two leading AI companies now generate annualized token sales of more than $100 billion, up over 500% from a year earlier. The Fed, he said, treats AI as "a new variable" that could become a new factor of production, with implications for economic growth and monetary policy. Still, Warsh said several questions remain unanswered: whether AI will deliver sustained productivity gains, whether token usage and labor are complements or substitutes, and whether the economic surplus created by AI will ultimately accrue to AI labs, chipmakers, energy suppliers, or cloud providers.
Federal Reserve Chair Kevin Warsh used his Jackson Hole speech to focus squarely on artificial intelligence, describing the current wave of AI development as a "turning point in history" whose pace has exceeded even the most optimistic forecasts made just a few years ago.
Capital spending growing at the fastest clip since 2021
Warsh said corporate capital expenditure is now growing at the fastest rate since 2021, rising roughly 9% over the past four quarters, with more than half of that activity tied to AI buildout. Going forward, he said he will be watching for a "second-order change" in AI capital spending — namely, whether the growth rate keeps accelerating.
Top two AI firms top $100 billion in annualized token sales
Warsh noted that two leading AI companies now record annualized token sales of more than $100 billion, up more than 500% from a year earlier. He said the Fed has come to view AI as "a new variable" that could become a new factor of production, one whose evolution will shape economic growth and the formulation of monetary policy.
Three questions without clear answers yet
Warsh also flagged a set of open questions: whether AI can deliver sustained productivity gains, whether token usage and labor will prove complementary or competitive, and whether the economic surplus generated by AI will ultimately be captured by AI labs, chipmakers, energy suppliers, or cloud service providers. On all three, he said, there is still no clear answer.
