Is relying on the AI sector too heavily a risk to the nation's long-term economic health?
Artificial intelligence factors significantly bolstered US economic growth in the first half of 2026, contributing 1.1 percentage points to GDP in the first quarter and 0.8 percentage points in the second. Excluding these AI-related contributions, the US economy expanded at an annualized rate of 1.4% during the same period.
Why it matters
Economic stability in the United States currently relies heavily on the performance of the AI sector, raising concerns that any reversal in this boom could trigger a substantial recession. The reliance on this sector is balanced against rising costs in energy, software, and hardware that impact the broader economy.
US computer and peripheral prices rose 10% year-over-year, while software costs climbed nearly 30% compared to the previous year. Additionally, US power prices reached levels 12% higher than the G7 average by the third quarter of 2026.

The details
AI investment is channeling capital through data centres, software development, and specialized power generation infrastructure. This surge in activity has spurred broader growth while contributing to a 25% increase in energy needs for data centres during 2025.
Timeline
Oxford Economics published the research briefing on October 29, 2026.
Data centre energy needs grew by over 25% throughout 2025.
AI factors added 1.1 percentage points to US GDP during 1Q26.
The US economy grew at a 1.4% annualized rate in 1H26, excluding AI factors.
Macro View
The current reliance on AI-driven growth mirrors the 1996-2000 dotcom boom, where technological investment dictated annual growth contributions. This trajectory reflects a similar economic reliance on capital-intensive sectors as seen during the late 1990s tech expansion.
Consumers are seeing significantly higher costs for computers and software, which increased 10% and 30% respectively over the last year. These shifts indicate that the AI-driven economic growth is accompanied by tangible price pressures on essential household and professional technology.
The takeaway
The US economy is currently being sustained by heavy investment in AI infrastructure, which has tangible effects on power and technology pricing for the public. Investors and citizens should note that this growth pattern makes the economy uniquely vulnerable to any sudden cooling in the AI sector.
