Quick Read

Peter Berezin warns AI is driving near-term inflation through surging electricity and chip costs the Fed may be dangerously underestimating.
-
Berezin labels today’s market an ‘earnings bubble,’ where investors assume current profit growth continues indefinitely, and history rarely rewards that kind of bet.
-
An AI capital spending bust or rising inequality concentrating gains among a few companies are the two scenarios most likely to cool the rally.

The stock market has spent much of 2026 climbing a wall of worry. Geopolitical tensions, stubborn inflation, and questions about economic growth have all taken turns rattling investors. Yet the major indexes continue hovering near record highs, driven largely by enthusiasm surrounding artificial intelligence.
Companies are pouring hundreds of billions of dollars into data centers, chips, and AI infrastructure, while investors reward those investments with ever-higher valuations. Now one Wall Street research firm is warning that the Federal Reserve may be helping fuel the rally in ways that could create problems down the road.
The Fed Is Missing AI’s Inflationary Side
In a recent client note, BCA Research Chief Strategist Peter Berezin challenged the growing belief that AI will automatically reduce inflation and justify lower interest rates. According to Berezin, the opposite may be true in the near term. AI demand is increasing costs for critical inputs such as electricity and memory chips, creating inflationary pressures that the Fed may be underestimating.
Here’s what the numbers tell us:
|
AI-Driven Cost Pressure |
Why It Matters |
|
Electricity demand from data centers |
Raises power costs and infrastructure spending |
|
Memory chip demand |
Keeps semiconductor pricing elevated |
|
Rising stock prices |
Encourages consumer spending and risk-taking |
Berezin argues that higher stock prices are creating a wealth effect. When investors see portfolio balances rise, they tend to spend more freely, which can keep inflation running hotter than policymakers expect. If the Fed keeps rates too low while this process unfolds, asset prices could become detached from fundamentals.
Why This Isn’t a Dot-Com Repeat — Yet
That said, BCA is not predicting an imminent crash. The firm’s MacroQuant model indicates stocks are overbought but have not reached levels typically associated with an approaching bear market. That’s an important distinction for investors. Overbought markets can stay overbought for months, particularly when earnings growth remains strong.
