AI may be engineering its own bust

Investors banking on AI growth and falling rates may be overlooking AI’s inflationary risk. The data center construction boom has ignited rallies across stocks and bonds, but the surge in demand for electricity, chips, and skilled labor is pushing prices higher. As “AI-flation” threatens to keep the Federal Reserve cautious, markets are heading into a year where the price of building the future could test today’s valuations.

By the numbers: The S&P 500 climbed 16% in 2025, lifted by monetary easing and enthusiasm for AI. However, the rally was unusually narrow. Just seven major tech groups generated half of all market earnings, pulling European and Asian equities — and US Treasury bonds — to record highs alongside them, Bloomberg data shows.

The inflationary feedback loop

While investors expect falling interest rates, the AI build-out could stall the easing cycle — or push rates higher. Hyperscalers including Microsoft, Meta, and Alphabet are locked in a USD multi-tn data center race. Capital spending is projected to hit USD 4 tn by 2030, with USD 440 bn next year alone, Deutsche Bank and Bloomberg estimate. This spending strains real-world resources — energy and advanced chips — creating bottlenecks and price pressures, analysts told Reuters, keeping US inflation above the Fed’s 2% target through 2027, Morgan Stanley predicts.

A pickup in inflation and tighter money as a result could be the “pin that pricks the bubble,” Royal London Asset Management Head of Multi Asset Trevor Greetham warns. Higher rates would hit speculative tech stocks hardest, raising funding costs while squeezing margins across the AI supply chain.

The strain is already visible in corporate earnings, where Oracle shares fell late last year after revealing soaring spending, Broadcom slid after warnings that high margins would be squeezed, and HP Inc. expects net income pressure in late 2026 as memory chip costs rise with data center demand.

AI’s bond market bonanza

The AI boom is also reshaping credit markets. To fund massive data center projects, tech firms and utilities are issuing record columns of high-grade debt, Bloomberg reports. This wave pushed corporate bond trading to record levels in 2025, averaging USD 50 bn a day, up from USD 46 bn in 2024.

As new AI-linked bonds flood the market, investors are rotating aggressively, selling older debt to make room for fresh paper. This has fueled a growing secondary market for private credit, which Morgan Stanley’s Rehan Latif called “the biggest single opportunity coming into 2026.” However, rising use of credit default swaps suggests that investors are quietly hedging against an AI unwind.

Is it a bubble?

With valuations stretched, comparisons to past bubbles are growing louder. The top 10 stocks now account for 40% of the S&P 500 — a level unseen since the 1960s — while the Shiller P/E ratio, a long-term, inflation-adjusted valuation gauge, trails only the highs of the early 2000s. However, today’s tech giants show stronger balance sheets and real bottom line growth.

The boom has a circular quality that unsettles skeptics. OpenAI’s USD 1 tn infrastructure pledge largely flows back to the same listed tech giants funding it, creating a closed revenue loop that magnifies both gains and risks.

Still, Wall Street expects the stock market can secure a fourth consecutive year of gains in 2026, following double-digit increases from 2023 through 2025. However, the mood is one of cautious optimism, according to the Wall Street Journal. While analysts generally predict upward movement, they acknowledge the path forward will be tighter and more difficult than the torrid rallies of previous years.
