AI is not just about software anymore. It is a power and heat story.

As data centers grow, the real bottlenecks become electricity, cooling, and the grid upgrades that keep everything from frying.

That creates a quietly powerful theme: the companies selling the infrastructure behind the screens.

What if you could add an extra $6,361 every single month to whatever you've already saved for retirement?

That’s exactly what legendary hedge fund manager Larry Benedict is targeting with his "Skim Codes."

These simple 18-digit codes can work whether the market goes up OR down.

You don't need to analyze stocks.

You don't need to time the market.

You don't even need to pick winners.

Just type the code into an ordinary brokerage account for the chance to profit.

Larry has outlined all the proof, and he’s giving away the whole three-step system.

Watch the full breakdown here.

AI Power And Cooling: The Hidden Bottleneck Trade

Most investors chase the flashy part of AI. The less glamorous part is where the friction lives.

  • More AI workloads → more servers

  • More servers → more power draw + more heat

  • More power + heat → more grid upgrades, switchgear, transformers, cooling gear, and long-term power contracts

This theme matters because the constraint is physical. If the grid is tight and lead times stay long, the companies that can ship critical gear and build infrastructure can keep pricing power longer than the market expects.

What we want to see to stay bullish

  • Backlogs that stay elevated

  • Lead times that stay tight but manageable

  • Hyperscaler capex that stays sturdy

  • More long-term power deals tied to data centers

What can ruin the party
If AI capex slows, permitting delays pile up, or supply finally catches up and pricing softens, the bottleneck trade can deflate fast.

Vertiv (VRT)

What it does: Power and cooling equipment for data centers, including thermal management systems and infrastructure that keeps high-density racks running without melting down.

Why it fits: If AI is the brain, this is the air conditioning and electrical backbone. As racks get denser, cooling becomes less of a nice-to-have and more of a survival skill.

Demand can accelerate when customers realize their shiny new servers are also tiny space heaters.

What could go right:

  • Orders and backlog stay fat, which supports multi-quarter visibility.

  • Margins improve if pricing holds and execution stays clean.

  • More retrofits, not just new builds. Older facilities need upgrades when AI workloads move in.

What to watch next: Backlog trends, margin commentary, and any signs customers are still rushing capacity online.

Also watch whether lead times stay supportive without turning into customer frustration.

Risk: If data center timelines slip or spending pauses, this can cool off quickly, pun intended.

Eaton (ETN)

What it does: Electrical components and power management gear like breakers, switchgear, and systems that safely distribute electricity through buildings and industrial sites.

Why it fits: Every data center build is basically an electricity routing problem with a concrete wrapper.

Eaton shows up where power has to be controlled, protected, and delivered reliably. It is not a pure AI play, which is the point.

It benefits if AI is booming, and it still has other demand engines if AI gets moody.

What could go right:

  • Tight supply keeps pricing rational, not cutthroat.

  • Capacity expansions translate into higher volumes without margin giveaways.

  • Electrification trends add a second tailwind outside data centers.

What to watch next: Lead times, backlog, and any indications that customers are still ordering far ahead.

If the company is still talking about strong demand and disciplined pricing, that usually means the pipeline is not drying up.

Risk: Industrial names can trade like economic mood rings. Even good fundamentals can get punished in a growth scare.

Quanta Services (PWR)

What it does: Builds and upgrades the grid: transmission lines, substations, and utility infrastructure. Think of it as the crew that makes “more power capacity” real.

Why it fits: Data centers do not run on optimism. They need interconnection, transmission capacity, and upgrades that take years, not weeks.

If the bottleneck is the grid, then companies that build the grid become the toll collectors for the AI era.

What could go right:

  • Utility capex keeps climbing as demand rises and reliability becomes a bigger political issue.

  • Backlog stays strong, supporting multi-year visibility.

  • More “data center adjacent” projects show up as regions scramble to support new campuses.

What to watch next: Backlog growth, project pipeline updates, and commentary on permitting and timing.

You want a story where work is not just planned, it is actually being awarded.

Risk: Timing can be lumpy. Permitting, local politics, and weather can push projects around like furniture in a small apartment.

Constellation Energy (CEG)

What it does: Power generation at scale, with meaningful nuclear exposure. In plain English: lots of reliable electricity without needing the wind to cooperate.

Why it fits: Data centers crave steady, predictable power, and they increasingly want long-term deals that lock in supply.

When power demand surges, the market tends to rediscover how valuable dependable generation can be.

What could go right:

  • More long-duration power agreements tied to large energy users.

  • Tight power markets support attractive pricing.

  • Nuclear stays in the “strategic asset” bucket as reliability becomes a bigger concern.

What to watch next: Signals around contract renewals and pricing, plus any updates on large customer demand.

If you see more chatter about long-term supply deals, that is the theme showing up in real dollars.

Risk: Power is part markets, part regulation, part politics. It can trade headline to headline.

nVent Electric (NVT)

What it does: Electrical connection and protection products like enclosures, cable management, and systems that keep equipment organized, protected, and compliant.

Why it fits: This is the quiet backbone trade. When data centers and grid projects ramp up, there is a long list of required components that never get the spotlight but still get purchased on schedule.

These are the “boring but mandatory” line items.

What could go right:

  • Infrastructure buildouts lift volume across multiple end markets.

  • Mix improves if higher-value data center and industrial products grow faster.

  • Execution stays steady, which is underrated and often rewarded.

What to watch next: Order trends tied to data centers and infrastructure, plus margin stability.

If the company can grow without getting sloppy on profitability, it can be a nice complement to the bigger names.

Risk: Less flashy names can be ignored until a quarter disappoints, then suddenly everyone remembers to care.

If this theme keeps working, it will not be because AI feels exciting. It will be because the physical bottlenecks stay real: power, cooling, and grid capacity.

These five picks sit in different parts of that pipeline, so you are not betting on one single choke point. 

Now it is just a matter of watching the follow-through with backlogs, lead times, and capex plans.

If those stay firm, this trade may keep humming. If they soften, we take the hint and keep our fingers off the thermostat.
