X-energy designs the Xe-100 high-temperature gas-cooled small modular reactor and manufactures the TRISO-X fuel it runs on, targeting industrial and data-center power.

Amazon — 投資方 · Amazon invested in X-energy's $700M Series C-1 financing round, alongside Dow and other funders, to support development of the Xe-100 small modular reactor and the TRISO-X fuel facility.來源：x-energy.com
Amazon — 合作夥伴 · Amazon and X-energy are collaborating to bring more than five gigawatts of new power projects online across the US by 2039, aimed at data-center demand. No power has been delivered: the Xe-100 is pre-deployment.來源：aboutamazon.com
X-energy's defensible assets today are regulatory and intellectual, not commercial. NRC Special Nuclear Material Licence SNM-7007, issued 13 February 2026 for a 40-year licence period, authorises HALEU fuel manufacture at Oak Ridge, and the company's own prospectus calls it the first-ever Category II nuclear fuel facility licensed in the United States; the Long Mott construction permit application for four Xe-100 reactors has reached its uncontested mandatory NRC hearing, scheduled for 22 September 2026. Neither has yet produced a reactor or a commercial fuel pebble: the prospectus expects TX-1 to be completed in the first half of 2028, and the 10-Q describes present revenue as derived from cost-share agreements such as the DOE ARDP. The HALEU feedstock the fuel depends on is a live dependency rather than a settled advantage — the prospectus states HALEU enrichment services are available only in limited quantities globally and that customers procure the feedstock, and the 10-Q discloses a definitive enrichment agreement with Centrus Energy announced 6 August 2026 under a phased approach with prepayments by X-energy to support Centrus's domestic capacity programme.
Real but unbuilt. The Q2 2026 10-Q shows the moat resting on regulatory standing rather than delivered product: the NRC completed the Environmental Assessment for the Dow Long Mott construction permit application on 18 May 2026 with a Finding of No Significant Impact, yet no Xe-100 has been constructed or operated and two counterparties supplied nearly all income, with the U.S. Government at 90.3% and Dow at 4.4% of total revenue and grant income for the three months ended 30 June 2026.
The IPO prospectus describes an 'intellectual property-driven business model': revenue is to come from technology fees for licensing the proprietary Xe-100 design plus proprietary TRISO-X fuel, and the company states it will not construct, own or operate the power plants. The durable assets are therefore patents and NRC licences, not plant, installed base or scale.
The prospectus records X-energy as one of two awardees under the DOE Advanced Reactor Demonstration Program, and it holds the Oak Ridge HALEU fuel-fabrication licence; but it is not the NRC design-approval leader — the NRC issued a standard design approval to NuScale for the US460 small modular reactor, published at 90 FR / Federal Register document 2025-10123 on 4 June 2025, while the Xe-100 is being licensed indirectly through a customer's Part 50 construction permit and holds no design certification or approval of its own.
Nothing has been priced in a market yet. The prospectus states the Xe-100 technology fee is a benchmarking assumption to be 'negotiated on a case by case basis' with no assurance customers will accept the proposed structure, and that Amazon holds first-priority manufacturing queue slots across 2031-2039, a right of first refusal and most-favoured pricing; the 10-Q records a 2025 warrant issued to a related-party customer with a $162.7 million grant-date fair value accounted for as consideration payable to a customer, i.e. a reduction of the transaction price.
Upstream supplier of reactor technology and TRISO fuel to industrial-heat and data-centre power buyers; it licenses the design and fabricates the fuel rather than owning or operating the plants.
Reactor development and lifecycle services · Nuclear project development and lifecycle services
Site engineering, licensing support, procurement, construction support and long-term operations and maintenance services wrapped around Xe-100 deployments — the line that produces essentially all of today's reported revenue.
利基市場
Services are performed for a very small set of counterparties: the U.S. Government and Dow accounted for 90.3% and 4.4% of total revenue and grant income for the three months ended 30 June 2026, and 90.9% and 4.4% for the six months.
中等
The work is tied to X-energy's own design, but nothing about it is exclusive or contracted at scale: the 10-Q says the company only expects the number of services and the share of revenue from them to grow as offerings are refined, first with Dow and the early Amazon and Centrica projects.
HALEU-based TRISO pebble fuel for the Xe-100 and for other TRISO-fuelled reactor designs, to be manufactured at the TRISO-X Fuel Fabrication Facility in Oak Ridge, Roane County, Tennessee.
挑戰者
The NRC issued Special Nuclear Material Licence No. SNM-7007 to TRISO-X on 13 February 2026 to operate the facility and to possess and use special nuclear material to manufacture HALEU fuel — but the licence authorises a facility, not output, and the notice records no commercial production.
深
Issuance required a published NRC record of decision, and the licence authorises possession of enriched uranium containing less than 20 weight percent uranium-235 for a licence period of 40 years, subject to conditions listed in the materials licence — a permission granted through a multi-year adjudicated process rather than bought.
XENITH microreactor · Microreactors
Compact 3-10 MWe high-temperature gas-cooled microreactor running on TRISO fuel in compact rather than pebble form, aimed at remote and defence installations.
未知
The prospectus states XENITH 'is not yet operational but is currently exploring commercialization opportunities', so it has no established market position to band.
中等
Development rests on roughly $60.0 million of U.S. Department of Defense Project Pele awards across 2020, 2021 and 2023, and the prospectus notes that the period of performance for the XENITH microreactor has expired while the Project Pele period of performance remains active.
Xe-100 small modular reactor · Advanced nuclear reactors (HTGR SMR)
80 MWe / 200 MWth high-temperature gas-cooled reactor module, marketed in a four-module configuration and licensed to customers for technology fees rather than owned and operated by X-energy.
挑戰者
No Xe-100 has been built or operated. The four-reactor, 800 megawatt-thermal Long Mott Generating Station is still only a construction-permit applicant: the NRC has scheduled the uncontested mandatory hearing for 22 September 2026 with the hearing record open until 6 October 2026.
深
Entry runs through NRC Part 50 commercial licensing under section 103 of the Atomic Energy Act. Long Mott Energy submitted the application by letter dated 31 March 2025 and, seventeen months later, has a scheduled mandatory hearing but no permit; the NRC also received a petition to intervene and request for hearing on 11 August 2025 and describes the proceeding as ongoing.
X-energy and AEP announced a joint development agreement to evaluate a proposed 960 MW Xe-100 reactor project in Sullivan County, Indiana. Amazon will provide certain development funding. The project remains subject to feasibility work and future approvals.
X-energy's TRISO-X subsidiary advanced its TX-1 fuel fabrication facility to the next phase of construction. TX-1 is the plant intended to supply the TRISO fuel the company's Xe-100 reactor runs on; no figures beyond the phase advance are stated in the cited article.
