IMF Scenario Sees AI Market Correction Cutting Global Output 1.1% by 2028

“The combined effect is a large decrease in global activity, which is 1.1 percent lower than that in the baseline by 2028, with larger losses in the United States (1.8 percent lower) and Asia (1.7 percent lower).”

The International Monetary Fund’s October 2026 World Economic Outlook models how a sharp reversal in AI investment could push global output 1.1% below its baseline by 2028. The scenario combines a pullback in technology spending with falling asset prices, tighter credit and weaker demand. It is a stress test, not the Fund’s central forecast.
The warning arrives as AI-related investment helps support growth amid the economic shock from the war in the Middle East. The IMF projects global growth of 3.1% in 2026 and 3.4% in 2027. In a separate briefing on financial stability, the Fund lists an AI-related market correction among three risks that could trigger market turmoil and tighter financial conditions, alongside higher yields and cyber threats.
From weaker returns to falling output
The outlook’s “Market Correction” scenario starts with AI productivity gains failing to materialize. That reassessment sharply cuts technology-sector investment, concentrated in the United States, and triggers a fall in asset prices. In the model, US equity prices drop 20% in 2026 and prices elsewhere fall 15%.
The first-stage economic hit comes from less investment and lower demand for technology goods. The IMF estimates that unwinding AI-related investment directly reduces global GDP by as much as 0.4% and investment by as much as 1.3% by 2028. That direct investment effect is part of the scenario’s broader output impact, not an additional amount to add on top. The retreat also affects Asian economies that supply high-end technology goods, with the region’s GDP about half a percent below baseline by 2029.
Financial spillovers add to the shock
The scenario does not stop at fewer data-center and technology projects. Lower share prices weaken household wealth and consumption, while reduced investor appetite raises borrowing costs for companies and governments. The IMF estimates that global consumption falls 0.6% by 2028 as financial conditions tighten.
The report says these effects leave global output 0.6% below baseline, with stress in sovereign bond markets and reduced demand for US assets subtracting a further 0.3%. Those two stated amounts total 0.9%, not 1.1%; the report separately gives a combined modeled shortfall of 1.1% by 2028 but does not reconcile the remaining 0.2 percentage point in that breakdown. The United States fares worse than the global average, with output 1.8% below baseline, while Asia’s shortfall reaches 1.7%. The scenario assumes the investment and asset-price shocks fade over the outlook period.
The IMF’s warning is about dependence
The report’s concern is not that AI investment must collapse, but that the growth outlook has become exposed to a narrow set of expectations about future returns. If firms spend heavily before productivity gains or revenue arrive, weaker expectations can hit both corporate investment and the market values supporting household and business spending. In its financial-stability briefing, the IMF also says optimistic earnings forecasts and large investment plans make an AI-related correction a risk.
The 1.1% figure describes output below baseline in a modeled downside scenario, not a prediction that global GDP will contract by that amount. The IMF’s stated message is to strengthen financial-system resilience before a shock hits, while recognizing that a reversal in AI investment could spread from technology spending into stock prices, credit conditions and trade.
