Tech Spending Is Carrying the Entire Economy

Here's an uncomfortable fact about the latest U.S. GDP numbers: they look great, but they're riding almost entirely on one sector. Deutsche Bank analysts Adrian Cox and Stefan Abrudan recently pointed out that AI-related investments are basically holding up the entire economic expansion right now. Take away tech spending, and the picture gets pretty grim—the analysts suggest the country would be "close to recession" this year, since spending in other sectors has essentially flatlined since Covid.

The U.S. economy expanded at a 4.3% annualized rate in the third quarter of 2025, according to the Bureau of Economic Analysis. That's strong growth by any measure, but the composition of that growth is what has Deutsche Bank raising eyebrows. AI investments aren't just contributing to GDP—they're anchoring it.

The scale of this spending is staggering. Deutsche Bank projects that hyperscalers will pour a cumulative $4 trillion into AI data centers through 2030. To put that in perspective, that's ten times the inflation-adjusted cost of the entire Apollo moon-landing program from the 1960s. And unlike that government program, this is happening "with no guaranteed return," as the bank's analysts pointedly noted.

Is This a Bubble or a Supercycle?

The question everyone wants answered: are we watching a bubble inflate in real time, or is this the foundation of something genuinely transformational? Economist Mohamed El-Erian has observed that strong economic growth has come with elevated inflation, driven by resilient consumer spending and now reinforced by this AI-driven surge in capital investment.

Goldman Sachs Asset Management pushes back on bubble fears, emphasizing that most AI infrastructure buildout is funded through robust corporate cash flows rather than risky borrowing. That distinction matters—debt-fueled booms tend to end badly, while cash-funded expansion has more staying power.

Daniel Newman, CEO of Futurum, takes an even more bullish view, calling AI a multi-decade technology supercycle rather than a bubble. He acknowledges that hype and overspending by some companies can create bubble-like appearances, but argues that core infrastructure players like Nvidia Corp (NVDA), Google (GOOG) (GOOGL), and Microsoft Inc. (MSFT) are generating real revenues and building sustainable businesses.

Even skeptics see nuance. Billionaire Bill Gates, Microsoft co-founder, acknowledged the existence of an AI bubble but clarified it's nothing like the 17th-century Tulip Mania. Instead, he compared it to the early internet era—a period marked by excess and spectacular failures, but also the foundation for genuinely transformative companies and technologies.

The tension here is real. On one hand, you have unprecedented capital deployment with uncertain returns propping up national GDP growth. On the other, you have serious companies with strong balance sheets making calculated bets on infrastructure they believe will define the next generation of computing. Whether this looks brilliant or reckless probably depends on where we are five years from now.
