Yesterday was not a great day to own Caterpillar.
The industrial heavyweight tumbled Wednesday as Baird Equity Research downgraded the stock to neutral from outperform, citing a growing moratorium on computing facilities construction, including one issued by New York State, as part of an emerging nationwide trend. Caterpillar has been performing like a tech stock this year as investors bet on ever-growing demand for construction equipment resulting from the data center buildout. The stock is up more than 30% year-to-date and more than 85% from a year ago.
That is an unusual sentence to write about a company that makes excavators.
But here is the thing. The AI trade found Caterpillar in a real way. While market attention often fixates on chipmakers and software giants, CAT is supplying the foundational picks and shovels needed to build and power the colossal data centers driving AI’s expansion. In Q1 2026, revenue reached $17.4 billion, up 22% year over year, with a record $63 billion order backlog, up 79% from a year earlier, predominantly fueled by AI infrastructure projects.
In response to the surge in orders, the company plans to nearly triple large engine production capacity by 2030 from 2024 levels. That is not a company hedging its bets on AI demand.
So why does this feel complicated right now?
The trailing P/E ratio is around 47x and the forward P/E is near 37x. That forward P/E is notably above CAT’s 3-year and 5-year averages, and the 20-year average P/E for the stock sits at roughly 22x. You are paying more than double the historical multiple for a company whose core industrial cycles are notoriously lumpy.
Slight tangent. Worldwide spending on AI could reach $2.59 trillion in 2026, up 47% year over year, according to Gartner Research. That spending covers the construction of chip factories and AI data centers. The demand is real. The question is how much of it Caterpillar actually captures, how durable it is, and whether state and local opposition to data center projects starts to slow the pipeline.
Ahead of Q2 earnings on August 4, analysts expect EPS of $6.25, up 32.4% from the year-ago quarter. Citi raised its price target to $1,100 and Oppenheimer raised to $1,105, both maintaining bullish ratings ahead of the print.
Here is where I land on this. The business has genuinely changed. Caterpillar’s Power Generation segment is seeing strong demand with record order backlogs linked to AI infrastructure projects. A new role powering large AI data centers puts the company directly in the path of long-term computing and energy buildouts. Its Power Generation segment is now closely linked to key AI infrastructure projects.
But the market has priced perfection into a cyclical industrial. That is a risk even the most compelling fundamental story cannot fully absorb. August 4 is when the Q2 numbers have to justify everything the stock has done in the last twelve months. If construction momentum is even slightly softer than expected, the downgrade will look prescient. If the backlog holds and margins improve, the AI infrastructure thesis gets another chapter.
One number decides it all. And right now, the market is not sure which way it goes.
