I recently came across an interesting chart that got me thinking.
It breaks down the annual growth rate of private fixed investment in the U.S. from 2010 to 2026 into two segments: AI-related investments (in blue) and all other industries (in yellow-green).
What’s truly concerning?
Between 2025 and 2026, that yellow-green segment is projected to turn negative. This means that, aside from AI, nearly all other sectors are pulling back on capital expenditures.
Meanwhile, that blue bar is skyrocketing.
Investments in data centers, computing power, communication infrastructure, and software—these AI-related expenditures are the ones dragging overall investment growth back into positive territory.
Put simply, the entire U.S. economy's investment growth is currently standing on just one leg—AI.
What does this indicate?
*First, AI isn’t just a bubble narrative; real money is being poured into it. *
Companies aren’t just talking about AI; they’re building data centers, buying GPUs, and expanding power grids. This level of capital expenditure can’t be sustained by mere storytelling.
*Second, other industries are pulling back. *
In a high-interest-rate environment, traditional sectors are clearly scaling back their investment intentions. Real estate, manufacturing, retail—they're all waiting on the sidelines. Only the AI sector continues to double down against the odds.
Third, this is a double-edged sword.
Over-reliance on a single growth engine is inherently fragile. If the return on AI investments takes longer than expected or if policies tighten, that leg could buckle, leading to troubling overall data.
Honestly, the last time I saw a similar structure in investment was around the year 2000 when internet-related investments dominated.
We all know how that ended.
But unlike then, the infrastructure investments in AI today are yielding real outputs—computing power is in use, models are running, and businesses are deploying solutions. It’s not just burning cash on empty promises.
So instead of asking, "Is AI a bubble?" perhaps we should be asking a more practical question: When all other engines have stalled, has your business connected with AI?
