Nuclear Just Powered an NVIDIA Chip

On July 1, on a stage in the high desert of Emery County, Utah, a two-year-old startup did something no American company had ever done.

It ran an NVIDIA AI chip on electricity straight from a nuclear reactor.

The setup was almost absurdly simple.

A Valar Atomics engineer plugged an NVIDIA Blackwell-powered desktop into a circuit that ran back into the reactor hall, where uranium atoms were splitting off about 100 kilowatts of heat. The chip lit up and ran a live website that anyone in the world could pull up while the reactor was hot.

To be fair, the wattage was nothing to brag about, barely enough to run a desktop and a web page, but…

…The meaning was everything.

The flagship chip at the dead center of the AI economy just drew its power from a reactor sitting a hundred feet away, in the middle of nowhere, with no grid in sight.

That same day, Valar and NVIDIA said they would jointly design a 30-megawatt data center built on that reactor, cooled with almost no water.

I have watched this AI trade for years, and that stage in Utah put a period on it.

Whoever wins the AI race from here has to answer a question that has nothing to do with silicon: Where does the power come from?

Data Centers Are Coming for 12% of the Grid

A single large AI campus can pull more electricity than a mid-sized city.

Stack up the buildout already announced, and the numbers stop looking like an industry and start looking like a second national grid. By 2028, data centers could eat as much as 12% of all the electricity generated in the United States.

That power has to run 24 hours a day, and it cannot flicker while a model is mid-training.

Solar and wind are cheap and getting cheaper, but a training run can't pause for a cloudy week, and the batteries that would carry a multi-day lull at this scale are still years and a fortune away.

A data center wants power that never blinks. The companies building them keep signing the two sources that deliver it, and only one of those is carbon-free at scale.

Meta, Microsoft, Amazon, and Google Already Signed

Look at what is already on paper.

Thirteen nuclear-for-AI deals were announced across the industry, which is roughly 9.8 gigawatts of committed power.

Meta contracted for up to 6.6 gigawatts. Microsoft signed a $16 billion deal to pull Three Mile Island out of retirement. Amazon put $700 million into an advanced reactor company and is building a nuclear-powered campus worth north of $20 billion. Google took 500 megawatts of small reactors.

These four have better data on what AI actually costs to run than anyone alive.

All four looked at the next decade and decided the one asset worth locking down for twenty years was a nuclear power contract.

When four of the most powerful and richest companies on earth independently make the same twenty-year bet, they are telling you where the shortage is.

Five Inches of Fuel, 165 Years of Power

Nuclear is that carbon-free source, and it delivers with a fuel whose density belongs to a different universe.

Isaiah Taylor, the Valar founder, laid it out for the crowd.

A gallon of gasoline moves your car about 20 miles. A candy bar holds enough chemical energy to walk you three. The energy locked inside a uranium atom is not on that scale at all.

Taylor told the room that the concentrated fuel in that first reactor would fit inside a cube five inches on a side and that it holds enough energy to run the thing for 165 years.

The newest designs also bury the fears that killed nuclear for a generation.

Valar's reactor is cooled by helium instead of water, so it can run in the desert without touching an aquifer.

Its fuel is sealed in ceramic-coated pellets that shed their own heat if every system fails at once, with no pumps, no backup power, and no path to a meltdown.

On top of that, it’s hard to turn into a weapon.

It is waterless, walk-away safe, and proliferation-resistant, all at once.

These are the three objections that stalled nuclear for forty years, and this reactor answers every one.

173 Million Pounds Mined.
204 Million Burned.

Every reactor on every one of those announcement runs on uranium, and the math already doesn't work.

Last year the world mined about 173 million pounds of it and burned about 204 million.

That deficit is here today, before a single new AI reactor comes online.

The World Nuclear Association expects uranium demand to climb 28% by 2030 and to more than double by 2040.

Spot uranium sits around $85 a pound.

Citi says $100 to $125 before the year is out. A new mine takes ten years and a war with the permitting office to bring online. So the reactors are being ordered now, and the fuel to run them does not exist yet in the volumes required.

Central banks have printed their way out of every shortage for fifty years, but they have never once printed an atom. You can’t print uranium.

You’ve seen this movie already with tungsten, with copper, with scandium. The physical world sets the ceiling on the whole AI boom, and we are about to learn how low it really is.

America Split the Atom First. Now It Imports the Fuel.

Mining uranium is the easy step.

Before any reactor can use it, that uranium has to be enriched, and enrichment is where the entire chain narrows to a needle.

America invented this. The Manhattan Project built the world's first enrichment plants at Oak Ridge in the 1940s, and for a generation the United States enriched more uranium than anyone on earth.

Then the same thing happened that always happens.

Cheap imports showed up, the plants got expensive to run, and Washington let the capability rot. The centrifuges spun down. The expertise retired. And Russia became the largest enricher on the planet, feeding the same reactors that keep American lights on.

The small modular reactors that hyperscalers are now buying need an even more specialized, enriched fuel called HALEU, and almost nobody outside Russia makes it at scale.

The country that split the atom first now has to import the fuel to run its own future.

Congress already saw the trap.

It banned Russian enriched uranium in 2024, with temporary waivers that all expire on January 1, 2028.

Russia had been supplying close to a quarter of the fuel in American reactors, so in barely eighteen months, the country loses that supply with nothing close to enough of its own to replace it.

Federal money is now moving to rebuild American enrichment from almost nothing, because the alternative is an energy grid and a defense complex that run on a rival's fuel.

From the mines to the enrichment plants to the power lines feeding these campuses, this whole chain is where the next winners come from, and Premium members get first look at every name we uncover.

Australia, India, and Washington Are Racing for the Same Fuel

The scramble is already on the map.

On July 9, during the Indian prime minister's visit to Australia, the two countries signed a uranium export deal built explicitly around powering data centers, with India chasing 100 gigawatts of nuclear by 2047.

The Trump administration has ordered a quadrupling of US nuclear output by 2050 and is tearing up the old licensing timelines to get reactors built years faster.

Every one of those moves is a government admitting the same thing.

The demand is already locked in.

The supply chain to meet it barely exists.

Watch Where the Powerful Put Their Money

I grew up in a house where money was tight and nobody owned a share of anything.

What I know about money, I taught myself the hard way, by watching what powerful people do with theirs instead of listening to what they say into a microphone.

Right now the most sophisticated buyers alive are doing one thing.

They are locking up power and the fuel behind it, on twenty-year contracts, as fast as they can sign them.

A two-year-old company ran the most coveted chip in tech off a reactor it built from scratch.

Governments are rewriting energy law in real time.

When the people with the most money, the power, and the best information all reach for the same thing at once, that is the signal. Everything else is noise.

Audit Your Portfolio for Power and Fuel

Audit your portfolio for a single question: do you own anything that produces power, or the fuel that powers it?

If everything you hold is chips, software, and tech funds, you own the loud, visible half of this boom, the half that cannot run for one second without the quiet half almost nobody owns.

Ask yourself the honest question. If the grid got tight and enriched fuel got scarce tomorrow, would your portfolio benefit, or would it bleed?

You don't have to become a nuclear engineer. You only have to watch what the biggest players are buying, and decide whether you want a piece of it before the crowd figures it out.

Stop Reading About It

I’ll keep sharing all of our research. The thesis, the squeeze, the chokepoint, the map of where the smart money is already moving.

I give the diagnosis away in these pages every week, because it makes you a sharper investor whether you ever send me a dollar or not.

But the specific recommendations are the part I keep for Premium Members: the exact companies, the price we open a position, the size we take, and even the levels where we pull our original capital back out. A name without those four things is just a tip, and tips are how people get hurt.

Three of our open positions are up by triple digits right now, with the largest at better than 250%.

Seven have doubled far enough that we pulled every original dollar back out, so our starting capital is already home and the rest rides for free.

Seven of every ten open positions are green, and across the whole book our winners run more than three times the size of our losers.

We were early to physical uranium back when it was still a punchline, and earlier this year we closed one of our uranium developers for a 42% gain while the rest of the market was still looking the other way.

That is the bar anything new has to clear before it earns a spot.

Right now we’re working through a short list of companies that sit at the tightest points in this whole build-out, the spots the entire AI economy has to pay to get past.

A couple are large and obvious. Others are small enough that most investors have never heard of them.

When the entry is right, Premium Members get the name, the size, and the exit in a single alert.

Everyone else meets it later, on CNBC, after the first move is already gone.

You can keep reading about the physical world from the outside, or you can own a piece of what makes it run.

The digital world is a tenant of the physical one. The rent is coming due, and the physical world always collects.
