Fitch Warns AI Spending and Tech Valuations Create Major Global Credit Risk

The artificial intelligence boom and the growing threat of a market correction have emerged as major global credit risks, ratings agency Fitch has warned in its third-quarter Global Risk Outlook. The bluntest warning so far from a major ratings firm highlights rising anxieties that soaring technology valuations and unprecedented spending are racing ahead of uncertain future returns.

Valuations Approaching Dotcom Boom Levels

Fitch pointed out that the cyclically adjusted price-to-earnings ratio for the U.S. S&P 500 has climbed to levels close to those witnessed during the late-1990s dotcom boom. At the same time, U.S. corporate bond issuance surged 26% during the first half of 2026, driven largely by AI-related fundraising efforts. Companies including Amazon, Alphabet, Nvidia, Meta, Oracle, and SpaceX together issued $182 billion of investment-grade bonds, according to the ratings agency.

Capital expenditure commitments from Alphabet, Amazon, Meta, and Microsoft are projected to jump more than 75% this year to reach $700 billion. Fitch estimated that this booming IT investment directly added 1.4 percentage points to first-quarter U.S. GDP growth, while climbing equity prices have supported household spending through a wealth effect.

Uncertainty surrounding future AI revenues, regulation, competition, and labor-market disruption could trigger a significant and prolonged market correction with widespread macroeconomic implications.

Geopolitical Conflict and El Niño Add Pressure

Alongside tech market vulnerabilities, geopolitical tensions continue to cloud the global outlook. Fitch highlighted renewed fighting between the United States and Iran in recent weeks alongside a fresh closure of the Strait of Hormuz as critical near-term threats. Driven by higher energy prices resulting from these disruptions, the agency expects world economic growth to slow to 2.4% in 2026, with U.S. inflation ending the year at 3.7%.

A strong El Niño weather pattern adds another layer of risk. Droughts, floods, and severe storms associated with the weather phenomenon threaten to compound inflationary pressures from the U.S.-Iran conflict. Highly indebted, junk-rated countries remain particularly vulnerable as sharp food-price spikes complicate monetary policy, increase subsidy costs, and further strain public finances.

Financing Conditions and Consumer Markets Diverge

While global credit markets grapple with high-stakes tech valuations and geopolitical shocks, regional financing conditions present a different picture in consumer sectors.

Confidence in an economic soft landing has driven increased deal activity across debt and equity capital markets, mergers and acquisitions, and leveraged finance. At the same time, cross-border dynamics and upcoming U.S. elections are expected to create a dynamic operational environment for clients navigating the broader economic landscape.
