Tech giants are expected to spend trillions of dollars on AI infrastructure in the coming years as they race to build the data centers, chips and energy capacity needed to support artificial intelligence.
McKinsey previously estimated that AI-related data center infrastructure could require up to $7 trillion in investment by 2030 (1). That’s more than the size of Germany and Spain’s GDP combined, per World Bank data (2).

The question is: Where will all that money come from?
BlackRock (NYSE: BLK) CEO Larry Fink believes ordinary Americans could help provide some of that capital — not by writing checks themselves, but through the retirement accounts and investments that own stakes in the companies leading the AI race.
“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,” Fink said earlier this year at Texas State Technical College in Waco alongside Texas Governor Greg Abbott (3).
At the time, Fink estimated the nationwide buildout of data centers and energy infrastructure could total $10 trillion over the next 10 years.
Since then, the AI arms race has only picked up speed.
Tech giants are spending tens of billions of dollars to build the data centers, buy the chips and secure the electricity needed to power the next generation of AI.
Microsoft (NASDAQ: MSFT), Amazon (NASDAQ: AMZN), Alphabet (NASDAQ: GOOG) and Meta (NASDAQ: META) are among the companies leading that charge — and their massive AI investments are one reason so many investors’ portfolios are increasingly tied to the success of this technology.
Here’s how some of your retirement funds are already exposed to this colossal spending spree on a technology that could reshape the way millions of people work.
Ordinary Americans are exposed to the AI boom
Your 401(k) plan is likely exposed to 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). But there’s a catch: Many of these supposedly diversified funds have become increasingly concentrated in a handful of mega-cap technology companies.
At the end of 2025, 41% of the S&P 500’s market cap was concentrated in just the top 10 stocks, including familiar names like Microsoft, Amazon, Google and Tesla (NASDAQ: TSLA), 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.
If the thought of your retirement savings being increasingly tied to the success of this one industry makes you uneasy, there are ways to protect yourself.
