Amazon (AMZN) shares experienced a significant rally on Monday, climbing 4.98% to close at $262.45 after the tech giant revealed plans to finance a substantial nuclear energy facility. The $12.45 gain came as investors reacted positively to the company’s commitment to back a 960-megawatt nuclear power installation in Indiana. This strategic move reinforces Amazon’s dedication to securing reliable energy sources for its expanding data center infrastructure.
Nuclear power strategy drives AMZN stock momentum
Amazon stock demonstrated strong upward momentum throughout Monday’s morning session before settling near the $262.45 level during afternoon hours. The equity maintained robust gains with minimal pullback following its initial surge. The announcement represents a significant expansion of the company’s commitment to nuclear technology as an energy solution.
Under the terms of the arrangement, Amazon will serve as the anchor funding source and inaugural electricity purchaser for the Indiana facility. American Electric Power has been designated as the plant operator, while nuclear technology firm X-energy will deliver 12 Xe-100 small modular reactors. The planned location sits south of Terre Haute at a decommissioned coal generation site.
This deal represents the second major commercial collaboration between Amazon and X-energy, effectively tripling the capacity outlined in their earlier partnership. Amazon spearheaded X-energy’s $700 million Series C-1 financing round during October 2024. The two organizations have established an ambitious objective to bring five gigawatts of new nuclear power online throughout the United States before 2039.
Power plant to serve broader electricity grid
The planned 960-megawatt installation will feed electricity into the regional power grid rather than operating as a dedicated Amazon facility. That said, Amazon anticipates securing substantial electricity from the project to power its data center operations while other grid users also benefit. This structure aligns with Amazon’s comprehensive strategy to ensure adequate energy availability for its technology operations.
Development of the Indiana facility hinges partly on X-energy’s progress at its inaugural nuclear installation in Texas. X-energy is working to deploy four Xe-100 reactors at Dow Chemical’s Seadrift manufacturing complex to deliver both thermal energy and electricity. Construction has not yet commenced, though federal regulatory bodies have moved the construction permit application toward final approval stages.
Texas state regulators have initiated legal proceedings against Dow concerning alleged violations of water quality and solid-waste regulations at the Seadrift location. The enforcement action relates to environmental compliance issues at the industrial site and provides context for X-energy’s initial reactor deployment. The timeline for nuclear construction remains contingent on regulatory licensing approvals and successful completion of the Texas project.
Market response to expanded nuclear partnership
X-energy completed its public debut through a Nasdaq listing in April with shares priced at $23 per unit. The stock registered a 27% gain on its first trading day before experiencing a prolonged downturn. Current valuations reflect a nearly two-thirds decline from the initial offering price.
Following Monday’s Amazon partnership disclosure, X-energy stock jumped approximately 10% during premarket activity. However, the shares reversed course and traded marginally lower—down less than 2%—by the time of publication. The volatility accompanied news of the expanded commercial relationship with Amazon.
Small modular reactor technology promises to deliver cost savings through standardized engineering and factory-style production methods. Yet historical nuclear projects in America have frequently encountered massive budget overruns and extended construction timelines. Amazon’s latest nuclear commitment broadens its energy portfolio, while X-energy advances work on its first commercial reactor installation.
