Summer Economic Growth Boosted by Advanced Economies and Global Trade

Global economic expansion gathered momentum during the summer months as advanced economies experienced a distinct growth spurt and international trade remained buoyant, according to business-activity surveys.

Throughout economic history, traditional bellwethers have shifted to reflect changing market dynamics. Housing served as a primary gauge for decades due to its cyclical nature and sensitivity to interest rates, while globalization later pushed manufacturing Purchasing Managers’ Indexes and trade flows into focus, followed by consumer retail sales and employment data.

However, evidence indicates that artificial intelligence is emerging as a powerful new economic engine. Stephanie Aliaga notes that artificial intelligence-related capital expenditures contributed 1.1% to gross domestic product growth in the first half of 2025, outpacing the U.S. consumer as a driver of expansion.

Where AI Investment Appears in Economic Data

The clearest signal of this shift manifests in direct business investment figures. Technology-related categories contributed 4.3 percentage points to overall investment growth in the second quarter, effectively offsetting declines in other sectors, according to data from the U.S. Morgan Asset Management. Hardware has driven much of this activity. Investment in computers and related equipment rose 41% year-over-year, reflecting an intense wave of orders for servers and GPU systems. Meanwhile, data center construction reached a record $40 billion annual rate in June, marking a 30% increase from the prior year and serving as a rare bright spot within a challenged construction environment. Major technology hyperscalers, including Meta, Alphabet, Microsoft, Amazon, and Oracle, are projected to allocate $342 billion to capital expenditures in 2025. This figure represents a 62% increase over the previous year’s spending levels. Private companies such as OpenAI and Anthropic are likewise deploying significant capital to support the development of frontier models.

Growth Limitations and Economic Risks

Despite record spending figures, analysts caution that the broader macroeconomic impact of the artificial intelligence boom will likely remain measured. Not every dollar allocated translates directly to domestic gross domestic product gains, as substantial portions of technology hardware investment flow toward imported goods, which subtract from overall domestic output.

Furthermore, data centers employ relatively few workers once construction concludes, limiting the traditional multiplier effect through wage-driven consumer consumption compared to factories or corporate campuses. Grid capacity limits, permitting bottlenecks may also restrict expansion despite the availability of willing capital.

While current hyperscaler spending is supported by strong operating cash flows, historical precedent demonstrates that technology investment cycles carry inherent volatility. If future demand fails to meet aggressive projections, corporate spending adjustments could occur rapidly.

The AI buildout is adding resilience to the economy at a time when consumption is softening and rates remain elevated, and shows some independence to variables like interest rates, labor markets and even trade shocks.

The ongoing technology buildout provides a vital cushion against macroeconomic headwinds, though maintaining portfolio diversification remains essential to balance the promise of innovation against persistent structural risks.
