The Industrial Side of AI: Where the Money Is Actually Going

Manufacturers, engineers, fabricators, and contractors are capturing a massive share of the investment flowing into data centers. They’re also benefitting from significant federal tax incentives, creating a substantial financial windfall for companies participating in the AI buildout.

Thousands of miles of pipe are being welded, cooling systems are being fabricated, and industrial facilities are running around the clock to support the infrastructure behind AI.

That’s where much of the money is ultimately going.

One HVAC company in Texas offers a glimpse into the economic ripple effects of AI’s explosive growth. The business’ revenue in 2025 was more than twice what it was three years earlier. The catalyst: data centers.

Today, roughly one-fifth of the company’s projects are tied directly to AI data center construction. As demand has accelerated, so has the company’s ability to benefit from federal incentives designed to support domestic manufacturing and industrial investment. The company’s expected federal tax incentives are projected to nearly double between 2025 and 2026, with their credits increasing from $400K to $750K. They used this not only to subsidize the cost of their builds but also to make their bids on new projects more competitive.

One project in particular puts the scale of the opportunity into perspective. The company recently designed and fabricated piping for a cooling system destined for a data center owned by a hyperscale cloud provider.

The modern AI economy depends on massive amounts of cooling capacity. Every server rack generates heat, and every new data center requires extensive mechanical systems to keep equipment operating reliably. Before AI can answer a question, a physical facility has to be built, powered, cooled, and maintained.

This is why the estimated trillions of dollars expected to be invested in AI infrastructure over the coming years represent far more than a technology story. Some estimates place that investment between $3 trillion and $7 trillion globally. A significant portion of that spending is flowing to engineers, manufacturers, welders, pipefitters, fabricators, contractors, and other skilled trades that rarely make headlines.

For companies operating in these sectors, the opportunity extends beyond project revenue. Federal incentives designed to encourage innovation, engineering, and domestic production can create meaningful financial benefits for businesses investing in new capabilities, solving complex technical challenges, and scaling operations to meet growing demand.

The lesson: AI may be powered by software, but it’s being built by engineers, skilled tradespeople, and manufacturers.

The next wave of economic growth won’t be limited to tech companies. Many of the biggest winners may be the businesses supplying the steel, cooling systems, fabrication expertise, and industrial know-how required to turn trillion-dollar AI ambitions into physical reality.
