⚠ Data Centres Are Most of the StoryModerate threat

Caterpillar (CAT) — threat to the moat

Most of Caterpillar's fastest growth comes from data centres, which share one financing cycle and one forecast.

Power generation's growth rests heavily on one type of buyer. The CEO called the data centre market a primary driver for Power & Energy1, and on the same call an analyst raised "a concern on AI and data center demand in the out years"2.

Accelerating for five quarters.

The exposure is visible in the orders. Caterpillar announced an order for 2 gigawatts of generator sets for the Monarch Compute Campus of American Intelligence & Power, calling it one of its largest single orders for complete power solutions3. Some Power & Energy customers are placing orders as far out as 20304.

The concentration is of type rather than name: Caterpillar discloses no customer above 10% of revenue. But data centre builders share a financing cycle and a demand forecast, and if both turn they turn together.

The company says it looked more widely. On the second-quarter 2026 call the chief executive said Caterpillar took a broad view when it analysed where the new capacity would go5, and the fourth-quarter call said the additional capacity would serve a broad range of applications6. Whether the other applications can absorb the capacity if data centres slow is the open question.

The number that would expose the risk is power generation sales to users. A slowdown from +72%7 to single digits within a year would say the data centre boom is maturing faster than Caterpillar's capacity plans assume.
