AI Is About to Flood the Market With Electricians. For the Contractor Who Hires Them, That's a Cost Line, Not a Windfall

The story sounds like a gift to a quiet corner of the stock market. Nvidia’s CEO keeps telling young workers that electricians and plumbers will walk into six-figure careers building the AI data centers, and the tech giants are acting on it — Meta, Google and BlackRock have together pledged more than $265 million to train tradespeople for exactly that work. Operators warn the industry is a few hundred thousand workers short. The obvious trade for an investor who wants to ride the boom without buying a chip stock: buy the companies that employ those electricians — the specialty contractors wiring the buildings.

That trade is subtler than the headline. Because to a contractor, an electrician is not the prize. The electrician is the largest line item on the income statement. When the worker is scarce, the wage goes up — and a rising wage is a cost, not pricing power. The scarcity Nvidia wants to train its way out of pays out to the plumber at the wire. The question is how much of it is ever supposed to reach the plumbing company’s shareholders.

The shortage is real, and it is priced in dollars per hour

Start with the size of the constraint, because it is genuinely unusual. U.S. data center construction is on track to exceed $52 billion in 2026, and the industry needs several hundred thousand more workers — estimates of the 2026 shortfall run from roughly 349,000 to 499,000 people. The electrician deficit alone is measured in the hundreds of thousands over the next decade, with about 20,000 electricians leaving the workforce every year and close to a third of union electricians aged 50 to 70.

The economic stakes make the scramble understandable. A typical 60-megawatt data center delayed by a single month loses about $14.2 million in revenue, so operators pay up to keep crews moving. Data center trades already command wages up to 30% higher than standard construction — a journeyman electrician in Northern Virginia earns about $59.50 an hour, well over $120,000 a year plus benefits, and a foreman can approach $200,000 with overtime. That is the feel-good story’s other half: the buildout runs on pay premiums, and someone signs those checks.

The contractor at the gate, and what it actually earns

Now follow the money one layer down to the company whose entire job is hiring that labor. MYR Group is a specialty electrical contractor — one of the quieter names in the build — with two businesses: transmission and distribution work for utilities, and commercial and industrial electrical work that includes data centers and EV charging. On the surface it is exactly the “beneficiary” the headline promises. At the end of June it held a record $3.16 billion in backlog. In its fiscal second quarter revenue jumped 20% from a year earlier to roughly $1.08 billion, and earnings per share of $3.17 beat analysts by a wide margin.

Here is what the customer of the headline does not see. MYR’s gross margin has averaged only about 11% over the past five years — it reached 13.2% in the latest quarter — and its operating margin has hovered near 5%, against a five-year average below 4%. Its own investor materials list the three reasons a data center startup surge does not automatically expand margins: skilled-labor scarcity, wage pressure, and customer concentration. Industry data frames the same tension: data center construction starts are up nearly 100% year over year, but contractors carry roughly eleven months of backlog — three months more than in other commercial work — because they cannot get enough qualified hands to turn their promises into profit.

Being necessary gets you orders. Being scarce decides who keeps the money — and here the scarce unit is the electrician, who is being paid the premium as wages. The contractor’s scarcity is a cost. That is the whole distinction the soaring buildout narrative blurs.

The market already knows, and the price shows it

The valuation picture makes the point concrete. Among the electrical contractors, the market has already separated the crowd favorites from the ones it expects to keep spinning their wheels. Comfort Systems, the mechanical fan favorite, trades near 26 times enterprise value to EBITDA; IES Holdings near 22; while MYR and EMCOR sit around 15. That gap is the market’s judgment about which names convert the boom into margin and which merely roll more low-margin labor through the books.

None of this is a claim that MYR is cheap in some overlooked way. At roughly $284 it has climbed most of the past year — it is up around 57% over twelve months, and far from the low end of its own 52-week range — even as it sits well below its high. The point is sharper than “buy the dip”: the scarcity rent in this story is real, but the market has already priced the thinness of the contractor layer. The famous product — the AI boom itself — gets the headline. The step in the chain that decides how much ships is a skilled-trades labor pool that takes years and an apprenticeship to create, and the company standing at that gate earns a 5% operating margin for the privilege.

What the training actually changes

This is where the story stops being purely bearish, because Nvidia and the hyperscalers are not being charitable. Every electrician they train is, over time, a release valve on a cost that is squeezing their supply chain. Expanding the labor pool should gradually ease the wage premium — and that is genuinely good for a contractor’s margins, just not the way the headline flatters it. It is margin relief on a multi-year clock, arriving only after the apprenticeship years and the qualification process, not instantaneous pricing power, and it lands inside a layer that earns very little per dollar of revenue.

That is the part to keep straight. The theme — AI labor scarcity — is large. Its contribution to the earnings of the company that hires the workers is diluted by a double filter: the customer (a handful of hyperscale buyers with real bargaining power) and the worker (who is collecting the premium as wages). This is the purest exposure to the buildout, and therefore the least diversified mistake if the cycle turns.

So who keeps the money

The résumé of this boom’s hidden winner is not the plumbing company. The docile conclusion to the “Nvidia is training the plumbers” storyline is that the plumbers themselves — and the trades that install, wire and cool these buildings — capture the scarcity premium in wages, while the contractors that employ them convert record demand at single-digit margin under concentrated buyers. The clock on the scarcity rent runs on the training pipeline: watch the contractors’ gross margins and whether record backlog keeps converting into expanding margin and cash. Steady gains would mean the labor force is finally catching up to the demand. A slip would confirm the labor trap that the data already describes — and would be the moment the story’s most natural beneficiary turns out to have run on borrowed time.
