Massive capital spending by major technology companies on artificial intelligence infrastructure has become a key pillar of global economic growth, according to a senior Fidelity investment strategist — so much so that the world economy could already be in recession without it.
A senior strategist at Fidelity has made a striking claim: strip away the enormous sums that the world’s largest technology companies are pouring into AI data centers, chips, and infrastructure, and the global economy would likely be contracting rather than growing.
The argument centers on what economists call capital expenditure, or capex — the money businesses spend on physical assets and long-term investments. In recent years, a small group of very large technology firms, sometimes called hyperscalers for the vast scale of their cloud and computing operations, have been spending at a pace that rivals entire national economies. That spending flows into construction, semiconductors, power systems, and related supply chains, creating jobs and revenue across many sectors and countries.
Fidelity’s point is that this wave of AI-driven investment has quietly become one of the most important engines of global demand at a time when other parts of the economy — including consumer spending in some regions, manufacturing, and trade — have been under pressure. In that sense, AI capex is filling a gap that would otherwise leave overall growth uncomfortably thin.
The claim carries weight because it reframes how investors and policymakers should think about AI spending. Rather than viewing it purely as a bet on future technology profits, it suggests the spending is already doing real economic work in the present, acting as a form of private-sector stimulus.
Whether that support can last depends on whether technology companies continue to justify the outlays through revenue growth and profitability. Critics have noted that returns on AI investment remain uncertain, and a slowdown in hyperscaler spending — if companies grow cautious — could remove a significant prop from underneath global growth figures.
For now, the data broadly supports the idea that technology investment has been an outsized contributor to economic activity, particularly in the United States but with ripple effects in Asia and Europe through supply chains and component manufacturing.
How long AI capital spending can sustain this supporting role — and what happens to growth if it slows — is a question worth watching closely in the quarters ahead.
