X-Energy, Inc. (XE) Stock Price & How to Invest

X-Energy, Inc. designs advanced small modular nuclear reactors and manufactures the fuel that powers them. Its flagship Xe-100 is a high-temperature gas-cooled reactor sized at roughly 80 megawatts of electric output (200 megawatts thermal), aimed at industrial sites and data centers, and its TRISO-X fuel business makes the coated-particle fuel the reactors run on. Founded in 2009 and headquartered in Rockville, Maryland, the company is developing its first Xe-100 plant at Dow's Seadrift site on the Texas Gulf Coast under the U.S. Department of Energy's Advanced Reactor Demonstration Program, and has offtake and partnership arrangements tied to Amazon, Dow, Centrica, Talen Energy, and utilities in Kentucky.

The investment picture is that of a pre-commercial technology company, not an operating utility. As of July 2026 X-Energy trades around $16.50 with a market capitalization near $6.7 billion, while trailing-twelve-month revenue and grant income is only about $117 million and net losses run into the hundreds of millions. Its April 2026 IPO raised roughly $1.1 billion in net proceeds, giving it a substantial cash runway, but the thesis depends on regulatory approvals, on-time reactor construction, and converting memorandums and offtake agreements into paid, deployed reactors years into the future.

X-Energy is pre-commercial, so it generates large losses and has no proven history of building and operating reactors at scale. Trailing revenue near $117 million against a market cap of roughly $6.7 billion means the valuation is priced for deployments that are years away and not yet certain. Nuclear projects face long regulatory timelines, potential cost overruns, and construction delays, and the Xe-100 still needs NRC licensing and first-plant completion. Much of the pipeline consists of studies, offtake agreements, and memorandums rather than firm binding orders, and the company depends on continued government support and capital markets access. A shift in policy, a project setback, or dilution from future capital raises could weigh heavily on the shares.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see X-Energy, Inc.'s investor relations page or your broker.

• Share price: ~$16.50
• Market cap: ~$6.7B
• Revenue + grant income (TTM): ~$117M
• 2025 revenue: ~$94M
• Net loss (TTM): ~-$546M
• IPO net proceeds (Apr 2026): ~$1.1B

As of July 2026, X-Energy trades at a very high multiple of its modest revenue because the market is pricing future reactor deployments rather than current results. Q1 2026 revenue and grant income roughly doubled year over year to about $43 million, but losses remain large as the company invests in licensing, fuel facilities, and its first plant. The April 2026 IPO added roughly $1.1 billion of cash, funding operations toward its demonstration milestones.

There are three common ways to get XE exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so XE sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where XE fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

XE is a well-funded but pre-commercial nuclear reactor developer whose value rests on future deployments rather than today's financials.

Whether XE is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is XE a buy?, and where the stock could go from here in the XE stock forecast.
