Big Tech’s Nuclear Ambitions Fuel a New Energy Race for AI Data Centres
The world’s biggest technology companies are rewriting the rules of nuclear energy financing, pouring resources into next-generation reactor projects as the explosive growth of artificial intelligence continues to drive unprecedented electricity demand. Through a series of high-profile deals, industry giants like Meta, Amazon, and Google are positioning themselves as unlikely but powerful backers of America’s nuclear future.
Several US-based companies are currently developing small modular reactors (SMRs) — a newer class of nuclear technology that is smaller, more flexible, and easier to scale than traditional nuclear plants. Despite the promise these reactors hold, none have yet reached commercial electricity production, with projects still wrestling with financing challenges and the uncertainties that come with first-of-its-kind technology deployments.
The urgency surrounding AI-driven data centre energy consumption, however, is injecting serious momentum into the sector. Technology firms are not just expressing interest — they are actively signing contracts and putting money on the table.
Meta Platforms made headlines in January after agreeing to help fund the development of two Terrapower reactor units capable of generating up to 690 megawatts of power. The social media giant also secured a deal with Oklo to develop a 1.2GW nuclear technology campus in Ohio, signalling a long-term commitment to nuclear as a cornerstone of its energy strategy.
Amazon is partnering with X-energy with the ambitious goal of bringing more than 5GW of small modular reactor capacity online across the United States by 2039. Not to be left behind, Google has inked an agreement with Kairos Power, targeting the launch of its first SMR by 2030 — a timeline that would mark a watershed moment for the industry.
Big Tech Brings Financial Credibility to Nuclear Energy
According to Shioly Dong, senior analyst at BMI, a unit of Fitch Solutions, these tech giants are doing something fundamentally transformative by introducing their top-rated corporate balance sheets into a sector that has historically depended on heavily regulated utility models. “They create the revenue certainty that commercial banks will require for the construction debt,” Dong noted.
US electricity consumption is expected to rise by 1% this year and 3% next year, according to the Energy Information Administration, with data centres being the dominant driver of that growth. Against this backdrop, SMRs are increasingly viewed as more attractive financing propositions compared to conventional nuclear plants, largely because their modular design and shorter build timelines reduce the exposure to massive upfront capital costs.
Tim Winter, portfolio manager of the Gabelli Utilities Fund at Gabelli Funds, acknowledged the significance of these developments while stressing that risk remains a central issue. “The industry needs ‘someone’ to take on the risks of cost overruns and delays,” he said. “The degree the hyperscalers are willing to do that will determine just how much of a boost these agreements give the sector.”
Oklo spokesman Bonita Chester confirmed that AI-driven demand is pushing customers toward long-term agreements that directly support project development. The company’s deal with Meta, for instance, includes dedicated funding to secure nuclear fuel and advance the initial phase of its Ohio project — a concrete example of how these partnerships are moving beyond mere announcements.
There are early signals that institutional investors are beginning to take notice. Tess Carter, associate director of the energy and climate practice at Rhodium Group, noted that banks are showing growing enthusiasm. “We have started to hear that banks are getting excited and interested in deal-making in the space, which would be a big development,” she said, though she was careful to add that significant banking participation has not yet materialised.
Despite the optimism, major hurdles remain for what analysts are calling the “advanced nuclear” industry. High construction costs, technology risks, and regulatory licensing processes continue to keep large-scale institutional investment at bay. A looming skills shortage adds another layer of complexity, with the industry potentially competing against data centres themselves for skilled tradespeople such as electricians and pipefitters, according to a recent report by the Nuclear Scaling Initiative.
Chester summed up the challenge candidly: “Commercialisation and large-scale deployment still depend on execution across licensing, fuel supply, construction and financing, so demand alone is not the only factor in accelerating commercialisation of advanced nuclear.”
The convergence of Big Tech’s financial firepower and the urgent energy needs of AI is undeniably breathing new life into America’s nuclear ambitions. Yet the path from promising deals to functioning reactors remains long and complex, requiring the industry to solve not just a funding puzzle, but a far broader set of technical, regulatory, and workforce challenges before the nuclear renaissance becomes a true commercial reality.
