Caterpillar stock (CAT) skyrockets 62% in 2025 as AI data centre generator demand sparks investor frenzy

Caterpillar stock: Caterpillar shares are surging this year, driven in part by rising demand for its natural-gas generators to power artificial intelligence (AI) data centers. According to the Wall Street Journal, the stock is up about 62% in 2025, fueled by projects such as a Utah development led by Joule Capital Partners, which plans to use more than 700 Caterpillar generators across six data centers, as reported by Ts2.tech.

Caterpillar Stock (CAT) Surge on AI Data-Center Generator Demand

The company is investing heavily to meet growing demand. Caterpillar plans to spend $725 million to expand its Lafayette, Indiana plant and aims to more than double turbine-engine production by 2030, following a 22% increase in power-and-energy sales to $7.8 billion in 2024, as per the report.

AI Data-Center Demand Shifts Caterpillar Beyond Construction Markets

The scramble for electricity has become a major challenge for AI data-center developers, as utilities face long interconnection queues and require new grid investments. To overcome these constraints, more projects are turning to on-site generation, placing power equipment directly at data centers to bring capacity online faster.


This shift is significant for Caterpillar because investors have traditionally viewed the company as tied to construction and mining cycles. Power equipment for AI data centers can smooth out these swings, keeping factories running even if demand for excavators slows.

Jonathan Sakraida, a senior CFRA analyst, told Invezz that “Caterpillar is reorienting its operations to be more in the power generation market,” framing the growth of its power-generation business as outpacing traditional construction and mining end-markets, as quoted by Ts2.tech report.
