Inflation-adjusted spending on information processing equipment exceeded real private residential fixed investment in the second quarter of 2024. Spending on information processing equipment reached $752 billion, while real private residential fixed investment was $748 billion. Adam Shapiro, vice president at the San Francisco Fed, said we’re seeing a pivotal shift in the US economy: investment is shifting away from residential investment and towards computers.

Real private residential fixed investment is down 18% from its early 2021 peak. The benchmark 30-year mortgage rate is nearly 7%. Housing starts fell 2.6% in August to an annualized pace of 1.275 million. The National Association of Home Builders reported builder sentiment fell to its lowest level in a year.

The 10-year Treasury bond yield hit its highest level since 2007. Treasury Secretary Scott Bessent said AI companies are almost yield-agnostic in their corporate debt issuance because they believe returns on AI build-outs will be high.

Nvidia stated on its August earnings call that the top five U.S. hyperscalers are on track to spend $800 billion in capital expenditure this year. S&P Global projects capital expenditures from Alphabet, Amazon, Microsoft, Meta, Oracle, and SpaceX will be $470 billion in 2025. The agency expects this amount to rise to $870 billion in 2026. By 2027, S&P Global estimates capital expenditures from these companies will exceed $1.3 trillion.

Alphabet reported negative cash flow earlier this year. S&P Global states operating cash flow from Alphabet, Amazon, Microsoft, Meta, Oracle, and SpaceX will collectively be negative in 2026 and 2027. S&P Global sees 2028 as an inflection point where revenue accelerates and capital expenditures flatten. S&P Global warns that aggressive AI infrastructure build-out could lead to overcapacity if future demand does not meet expectations.

Why It Matters

The crossover in investment categories signals a long-term reorientation of the U.S. economy toward digital infrastructure. As residential construction slows due to high interest rates, technology firms are absorbing capital that might otherwise flow into housing or other traditional sectors. This shift affects labor markets, supply chains, and regional development patterns.

The scale of projected spending by major technology companies implies a sustained commitment to artificial intelligence infrastructure. With cumulative AI infrastructure spending through 2050 potentially reaching $31.6 trillion according to PwC estimates, the current trend represents only the beginning of a multi-decade expansion. The outcome of this investment cycle will determine whether the economy achieves higher productivity or faces a period of excess capacity.

What's New

PwC states that 70% of AI infrastructure spending currently goes toward information and communications technology equipment. PwC projects that the proportion of AI infrastructure spending on information and communications technology equipment will rise to 93% by 2050. PwC estimates cumulative AI infrastructure spending through 2050 could reach $31.6 trillion.

How Sources Differ

PwC report projects that the proportion of AI infrastructure spending on information and communications technology equipment will rise to 93% by 2050. Bureau of Economic Analysis data shows spending on information processing equipment increased 51% from its early 2021 level.
