Fitch warns AI market correction emerging as major global credit risk

• U.S. S&P 500 valuations have reached levels close to the late-1990s dotcom boom, while major tech companies (Alphabet, Amazon, Meta, Microsoft) are projected to spend $700 billion in capex this year, up over 75%
• AI-related companies issued $182 billion in investment-grade bonds in H1 2026, contributing to a 26% surge in U.S. corporate bond issuance, with IT investment adding 1.4 percentage points to Q1 U.S. GDP growth
• Geopolitical tensions including renewed U.S.-Iran fighting and Strait of Hormuz closure, combined with strong El Niño effects, pose additional risks especially for 'junk'-rated countries facing food price spikes and fiscal strain

Summary: Fitch Warns AI Market Correction Emerging as Major Global Credit Risk

Ratings agency Fitch has issued its bluntest warning yet about AI-related market risks, identifying a potential AI correction as a major global credit threat in its Q3 Global Risk Outlook released July 28.

Key Concerns

AI Market Vulnerability: Fitch warns that unprecedented AI spending may be outpacing uncertain future returns. The U.S. S&P 500's cyclically adjusted price-to-earnings ratio has reached levels comparable to the late-1990s dotcom boom, signaling potential overvaluation.

Staggering Investment Figures:

• Major tech companies (Amazon, Alphabet, Nvidia, Meta, Oracle, SpaceX) issued $182 billion in investment-grade bonds
• Capital expenditure by Alphabet, Amazon, Meta, and Microsoft projected to surge over 75% in 2026 to $700 billion
• U.S. corporate bond issuance jumped 26% in H1 2026, driven largely by AI fundraising
• IT investment directly contributed 1.4 percentage points to Q1 U.S. GDP growth

Market Implications

Fitch emphasizes that AI has become deeply intertwined with U.S. economic growth and capital markets, creating significant systemic risk. A correction could trigger "widespread macroeconomic implications" due to uncertainties around future AI revenues, regulation, competition, and labor market disruption.

Additional Risks

Geopolitical: U.S.-Iran conflict and Strait of Hormuz closure threaten energy supplies. Fitch forecasts 2026 world growth at 2.4% and U.S. inflation ending at 3.7%.

Climate: Strong El Niño weather patterns could cause droughts and floods, particularly threatening junk-rated countries through food price spikes and strained public finances, especially in Latin America where Middle East supplies 30% of fertilizer.
