Wall Street Journal warns of AI investment bubble threatening global economy

AI investment bubble Wall Street Journal data center spending U.S. Treasury AI capital expenditure

The Wall Street Journal reported that the surge of investment in artificial intelligence could create a financial bubble that may burst and impact the global financial system. Analysts cite McKinsey’s forecast that worldwide data‑center spending could reach about $7 trillion by 2030, and warn that if AI‑related productivity does not keep pace with the scale of spending, market valuations could become unsustainable.

A U.S. Treasury analyst echoed the concern, stating that a collapse of an AI‑driven bubble would pose a high risk to the U.S. economy. Parallel reports from Russian Sputnik, citing the same Wall Street Journal analysis, highlighted the same bubble risk. Additional commentary from market analysts notes that AI capital expenditures may be nearing a peak, with projected AI spending climbing to roughly $1.2 trillion by 2027 and overall AI capex for 2026 potentially topping $7.5 trillion. The reports also flag longer‑term fiscal pressures, such as reduced tax revenues from AI‑displaced high‑income jobs and rising costs for unemployment benefits and retraining programs.
