Nuclear Firm Becomes First in US to Produce Advanced Reactor Power

Nvidia Corp (NASDAQ:NVDA) makes the graphics processors and AI chips that power much of the world's data center buildout, and the company just landed in an unexpected corner of the energy world: a nuclear reactor demonstration in Utah. On Wednesday, California startup Valar Atomics connected its Ward 250 advanced reactor to an Nvidia Blackwell chip, generating a small amount of power to briefly host a website. It marks the first time a next generation reactor has powered US hardware, and the two companies say they will now explore nuclear powered AI systems together.

NVDA shares closed at 196.93, up a modest 0.18% on the day, a sign investors are treating this as an interesting side project rather than a market mover. The stock carries a market cap of 4.74 trillion dollars, still comfortably the largest of any public company, and trades at a P/E of 30.02. Its 52 week range runs from 189.8 to 236.54, meaning shares are sitting closer to the low end of that band right now.

Why a Reactor Handshake Matters for Nvidia's Story

Nvidia's chips are the engine behind most large AI training and inference workloads, but that computing muscle comes with an enormous appetite for electricity. Data centers packed with Blackwell chips can strain regional power grids, and utilities across the country are already fielding requests for new capacity tied to AI expansion. Valar's demonstration, however small in scale, points to one possible answer: pairing chips directly with dedicated nuclear generation rather than waiting on grid upgrades.

Valar's reactor reached criticality last month, the point at which a fission reaction becomes self sustaining, and Wednesday's test built on that milestone by actually delivering usable power to run Nvidia hardware. The companies have not disclosed financial terms of their agreement, and it is worth remembering that no advanced US reactor design is yet commercially available. Valar is one of several startups racing to change that, but regulatory approval and scaled manufacturing remain years away.

Valuation, Momentum (RSI) and Yield on Nvidia

Nvidia's earnings per share currently work out to a P/E of 30.02, a multiple that reflects continued confidence in AI related demand even as the stock has cooled from its highs. The dividend yield sits at 0.51%, a small return that signals this is still very much a growth story rather than an income play. Momentum looks neutral: the relative strength index reads 43.85, below the 50 midpoint, suggesting the stock has drifted rather than surged in recent sessions.

The bull case rests on Nvidia's position at the center of AI infrastructure spending, and deals like the Valar partnership reinforce the idea that chipmakers are now shaping how power gets generated, not just consumed. If nuclear powered data centers become a real category, Nvidia's hardware sits at the heart of that demand. The bear case is more grounded in near term math: shares trade well off their 52 week high of 236.54, RSI shows tepid momentum, and a 30 times earnings multiple leaves little room for disappointment if AI capital spending cools or competition narrows margins.

Does Nuclear Powered AI Change Nvidia's Growth Math?

The honest answer is not yet. Wednesday's test produced a trickle of electricity, not a commercial power source, and Valar's technology still needs years of development and regulatory clearance before it could meaningfully offset the energy demands of Nvidia's customer base. What the demonstration does confirm is that chipmakers, utilities and nuclear startups are now actively experimenting with new power models for AI, and Nvidia's willingness to participate signals how seriously it takes the energy constraint on its own growth.
