IMF Warns AI Investment Crash Could Cut Global GDP by 1.1%

The International Monetary Fund (IMF) has warned that a sharp decline in artificial intelligence investment could threaten global economic stability, particularly if investors lose confidence in the technology industry’s ability to generate the profits needed to justify its enormous spending. In its latest economic assessment released on October 13, 2026, the IMF identified a potential AI market correction, rising government debt and escalating geopolitical tensions as significant risks to the global economy. The warning comes as technology companies continue investing billions of dollars in data centres, advanced processors and computing infrastructure to support increasingly capable AI systems. Although these investments have helped drive economic activity, the IMF cautions that excessive reliance on continued AI expansion could leave markets vulnerable if expected financial returns fail to materialise.

According to the IMF’s downside scenario, a steep fall in AI-related investment could reduce global gross domestic product (GDP) by approximately 1.1% by 2028, compared with the expected economic trajectory. The United States could experience an estimated 1.8% decline in output under the same scenario because of its significant exposure to AI-related investment and financial markets. Such a downturn could begin with falling share prices among technology companies and spread to the wider economy through reduced business investment, weaker consumer confidence and declining asset values. The IMF emphasised that this is a risk scenario rather than its central economic forecast. It also said that even under this adverse scenario, the resulting slowdown would not necessarily be severe enough to trigger a global recession.

One major concern is whether AI companies can generate enough revenue to justify their growing valuations and infrastructure commitments. Technology firms have committed substantial resources to purchasing chips, constructing data centres and developing AI products, while investors have provided considerable funding based on expectations of future growth. If businesses and consumers adopt AI more slowly than anticipated, or if the technology fails to deliver the expected productivity gains, investors could reassess the value of AI companies. The consequences could extend beyond the technology sector because large companies, smaller AI startups, lenders and infrastructure providers are increasingly connected through investments, borrowing arrangements and commercial agreements. The IMF warns that weaker expected revenues could make debts harder to service and undermine commitments based on future earnings.

The IMF has also highlighted the wider economic importance of AI infrastructure and trade. According to its assessment, trade in AI-related goods increased by 29% between 2023 and 2025, substantially faster than overall global trade, which grew by 8.3% over the same period. The fund said that without AI-related goods, growth in global trade would have been considerably weaker. This demonstrates how strongly the current expansion of AI infrastructure has become connected to manufacturing, international supply chains and investment flows. However, the concentration of AI development and infrastructure in a relatively small number of countries and companies also creates vulnerabilities. A slowdown in spending could affect semiconductor manufacturers, equipment suppliers, data-centre developers and economies that depend heavily on technology exports.

Beyond artificial intelligence, the IMF warned that rising public debt, higher borrowing costs and geopolitical tensions could intensify economic pressures. Its latest projections put global economic growth at 3.1% in 2026, slightly above its previous forecast of 3.0%, with growth expected to reach 3.4% in 2027 if key assumptions about energy prices and shipping conditions hold. However, a prolonged conflict in the Middle East that keeps oil prices above $130 per barrel through the first quarter of 2027 could reduce next year’s growth by approximately half a percentage point. The IMF is therefore urging governments to strengthen financial safeguards, manage public borrowing responsibly and prepare for potential shocks. For the AI industry, the message is that continued investment may create significant economic benefits, but sustainable growth will depend on whether companies can turn technological advances into reliable revenue and productivity gains.
