Tech giants are expected to spend a whopping $7 trillion on AI infrastructure by 2030, according to McKinsey (1). That’s more than the size of Germany and Spain’s GDP combined, per World Bank data (2).
If you’re wondering where all that money is coming from, the answer might surprise you: It’s your “savings accounts and pension accounts.” That’s according to BlackRock CEO Larry Fink, who made the prediction at the Texas State Technical College in Waco alongside Texas Governor Greg Abbott, according to 25 News KXXV (3).

“If we can get more and more Americans to think about growing with the United States, we will have far [more] than enough money to invest in this infrastructure,” said the banker. Altogether, Fink estimated, the nationwide build out of data centers and energy infrastructure could total $10 trillion over the next ten years.
Here’s how some of your retirement funds are already fuelling this colossal spending spree on a technology designed to take your job away.
Ordinary Americans financing the AI boom
Your 401(k) plan is propping up the AI boom, even if you’re not aware of it. That’s because a growing number of workers and savers have turned to passively investing in index funds in recent years, even as tech giants have become a larger part of these indexes.
As of April 2026, Americans collectively had $20.82 trillion invested in index mutual funds and ETFs, according to the Investment Company Institute (4). Traditionally, these index funds were well-diversified but that isn’t the case anymore. At the end of 2025, 41% of the S&P 500’s market cap was concentrated in just the top ten stocks, including familiar names like Microsoft, Amazon, Google and Tesla, according to RBC Wealth Management (5).
These tech giants are leading the data center and utility spending spree. “America is now one big bet on AI,” Ruchir Sharma wrote in the Financial Times (6). “AI better deliver for the U.S., or its economy and markets will lose the one leg they are now standing on.”
As one of the largest index fund providers (7) in the country, BlackRock has a front-row seat to this concentrated bet on AI. This is why Larry Fink’s comments are worth your attention.
