Jeremy Siegel said the tech sector is entering an unprecedented situation driven by an AI-driven rally and a memory-chip crunch.
This warning comes as investors navigate the tension between rapid technological growth and the Federal Reserve's aggressive efforts to curb inflation. The convergence of these factors creates a volatile environment where traditional market cycles may no longer apply.
Speaking on CNBC’s “Squawk Box” on June 5, 2026, Siegel, a professor emeritus of finance at the University of Pennsylvania’s Wharton School and chief economist at WisdomTree, said the current AI-driven rally is distinct from previous market bubbles. He said the movement is more like the Industrial Revolution than a typical speculative peak.
However, Siegel said these dynamics are colliding with the Federal Reserve’s current stance. He described the Fed's anti-inflation rhetoric as a "war on growth" [3]. This aggressive policy creates a complex backdrop for tech stocks, which are typically sensitive to interest rate shifts.
Despite these warnings, Siegel maintains a cautiously optimistic outlook for the broader market. He said he still sees about eight percent upside in the market over the next year [1]. He also referenced 5,000 points as a psychological level for the S&P 500 [2].
Market analysts remain divided on how to handle the current chip shortage. Some suggest the memory-chip crunch creates a buying opportunity, while others warn that investors should be cautious regarding temporary surges in chip profitability. Similarly, there is a contradiction regarding tech's vulnerability; while some argue the sector is less exposed to a growth slump and could benefit from future rate declines, others suggest the AI rally remains vulnerable if the Fed continues to tighten policy.
Siegel said, "We are approaching an unprecedented type of situation."
“The AI‑driven rally is different from previous market bubbles; it’s more like the Industrial Revolution.”
The shift from a speculative bubble framework to an 'Industrial Revolution' model suggests that AI is being viewed as a fundamental economic driver rather than a temporary trend. However, the conflict between structural growth and the Federal Reserve's restrictive monetary policy creates a high-risk environment where the cost of capital may offset the gains from technological breakthroughs.
