Sam Altman is the chairman of an organization that guarantees a brighter future for humankind.
No, it’s not OpenAI, the factitious intelligence firm he co-founded and now runs as CEO.
It’s an organization referred to as Oklo, and it’s creating the sort of nuclear energy expertise that many tech leaders — together with Altman himself — say they may want to gasoline future synthetic intelligence developments.
The proliferation of electricity-hungry knowledge facilities to energy our digital lives – and more and more, the AI expertise that tech giants say is the long run – now implies that vitality demand might quickly outstrip provide. And that will be an issue for tech companies who’re angling for his or her AI expertise to revolutionize virtually every thing about the way in which we dwell and work.
But whereas tech leaders have pointed to nuclear vitality as important to a local weather pleasant future, some business consultants surprise how a lot their investments will actually profit the broader public, reasonably than simply defending their very own companies’ capacity to function.
“I think the tech companies are looking out for their own interests, and whether those nuclear vendors are able to sell additional nuclear power plants for the public is another question,” mentioned Sharon Squassoni, a analysis professor at George Washington University who’s studied nuclear vitality and coverage.
It’s clear that extra vitality will want to come from someplace. Electricity demand from US knowledge facilities has grown 50% since 2020 and now accounts for 4% of the nation’s vitality consumption; that determine might develop to 9% by 2030, UBS analysts mentioned in a analysis observe earlier this month. And total energy demand within the United States is predicted to develop 13% to 15% a 12 months till 2030, probably turning electrical energy “into a much scarcer resource,” according to JPMorgan analysts.
The electrical energy wants of information facilities have also threatened to upend tech giants’ sustainability guarantees.
Tech giants have pointed to the good thing about nuclear vitality’s reliability versus different renewable vitality sources, similar to photo voltaic or wind. Microsoft in September secured a deal to reopen a reactor on Three Mile Island, the positioning of a 1979 partial meltdown in Pennsylvania, aiming to revive a distinct reactor by 2028 to energy its AI ambitions. Amazon and Meta have also begun working to lock in offers to safe future nuclear energy for his or her knowledge facilities.
“Data centers operate 24/7 and they need a stable supply of electricity. They can’t shut down because the wind is not blowing or the sun is down,” mentioned Anna Erickson, a professor at Georgia Tech who research nuclear engineering.
Oklo isn’t Altman’s solely nuclear vitality funding. The OpenAI CEO has also invested in Helion Energy, a nuclear startup that’s utilizing a distinct sort of expertise from Oklo. Facebook co-founder and now Asana CEO Dustin Moskovitz, LinkedIn co-founder Reid Hoffman and billionaire tech investor Peter Thiel’s enterprise capital agency, Mithril, have also invested in Helion Energy.
And Altman isn’t the one tech chief making an attempt to money in on the push towards nuclear.
Separately, TerraPower, which is backed and chaired by Microsoft founder Bill Gates, is within the early phases of constructing a brand new nuclear reactor in Wyoming. Google joined a $250 million funding spherical for nuclear startup TAE Technologies in 2022, and Amazon anchored a $500 million financing spherical for nuclear startup X-energy in October. Amazon founder Jeff Bezos has also invested in Canadian nuclear startup General Fusion.
As of August, Peter Thiel’s enterprise capital agency, Mithril, owned 5.3% of Oklo’s shares, and the billionaire tech investor has reportedly backed different nuclear startups. Tech investor Cathie Wood’s Ark Invest also invested in Oklo earlier this 12 months. (President-elect Donald Trump’s choose for vitality secretary, Chris Wright, chief government of the fracking firm Liberty Energy, also serves on Oklo’s board.)
Already, lawmakers are lining up to help increasing nuclear energy. President Joe Biden in July signed into regulation the Advance Act, a invoice designed to make it simpler, cheaper and quicker to allow and construct new nuclear reactors that acquired bipartisan help. And throughout this 12 months’s COP28 climate talks, the United States joined greater than 20 different international locations in pledging to triple international nuclear vitality capability by 2050.
Some consultants see the tech business’s funding as essential for pushing ahead an costly however clear vitality supply that might assist fight local weather change.
“Let’s face it, these guys who are doing AI right now, they’re the ones with the money, right?” Erickson mentioned.
Megan Wilson, chief technique officer at General Fusion, instructed NCS that “as we look at the interest by tech companies… in nuclear power, what we’re seeing is really a symptom of the broad recognition that we need clean, baseload power that is free of both carbon dioxide and methane emissions, that’s reliable and affordable.”
Although General Fusion remains to be within the technique of proving its expertise works, Wilson added that fusion is predicted to be an excellent safer possibility than fission, as a result of it’s combining atoms reasonably than separating them, and due to this fact is “very hard to start and very easy to stop.”
In the long run, the corporate expects its energy crops “will have a radiation profile very similar to that of a hospital that uses medical isotopes or has a cancer treatment ward,” Wilson mentioned.
But some consultants have raised considerations about heavy investments in nuclear by the leaders of an business recognized for pushing again in opposition to laws that might sluggish it down, even when it’s meant to enhance security.
“The problem here is that you have these Silicon Valley giants who have the clout, who have the power, to get a lot of what they want … and the industry’s attitude, first and foremost, is fight any regulation that would interfere with their plans,” mentioned Edwin Lyman, director of nuclear energy security on the Union of Concerned Scientists.
“I am very concerned that the safety and security rules that are really essential for protecting the public could take a real beating,” Lyman mentioned.
A TerraPower spokesperson instructed NCS, “It’s clear that the world needs more carbon-free, reliable power; and advanced nuclear energy has an important role to play in helping both the public and private sectors meet decarbonization goals in the face of energy demand growing exponentially. Studies show that we will not make our net zero targets without nuclear energy in the mix; anyone serious about meeting carbon-free targets needs to be planning to integrate nuclear into their energy portfolio.”
Oklo didn’t reply to requests for remark.
Oklo, which was based in 2013 by two MIT graduates, says it’s creating superior nuclear reactors to “produce abundant, affordable, clean energy at a global scale.” The firm’s identify was impressed by the Oklo area within the African nation of Gabon, the place scientists say Earth’s solely pure nuclear reactor existed some 2 billion years in the past.
Oklo is constructing so-called “fast reactors” that it says can create better energy output from much less gasoline — which means they’re smaller and cheaper — and will recycle used nuclear gasoline from different crops. It plans to promote energy from these smaller reactors immediately to clients, similar to knowledge heart operators, probably immediately on-site.
AI is predicted to remodel all the expertise we use within the coming many years, and “you want something that’s reliable and scalable and clean and (nuclear) fission is really well suited to do that,” Oklo CEO and co-founder Jacob DeWitte said in May.

Oklo’s inventory has doubled because it started publicly buying and selling in May following a merger with Altman’s special purpose acquisition company, AltC Acquisition Corp. That robust inventory efficiency comes as AI development is predicted to drive up demand for nuclear energy, though Oklo isn’t but making any cash.
But Oklo says it’s making progress towards its imaginative and prescient. The firm received approval in September to start website investigations for one in all its small reactors in Idaho, and it says it’s reached a number of agreements to promote future energy to knowledge heart operators.
But to date, these small modular reactors are “all theory,” with an extended and costly highway forward to really producing and promoting energy, in accordance to Squassoni.
Other recent US efforts to construct new nuclear reactors have been affected by delays and value overruns. The United States also faces hurdles to accessing sufficient fuel to energy new reactors, after restrictions on imports of enriched uranium from Russia started within the wake of its battle in Ukraine. The US authorities is combing via its personal nuclear stockpile to discover sufficient gasoline for some initiatives, whereas gasoline enrichment efforts get off the bottom.
Gates’ TerraPower broke floor in June on its nuclear reactor “demonstration” plant, Natrium, which it hopes will be operational by 2030. For now, development on the website in Kemmerer, Wyoming, is proscribed to non-nuclear parts, because it awaits full regulatory approval.
TerraPower says its design is smaller and easier than conventional nuclear reactors, and its system would use sodium for cooling, reasonably than conventional water-cooled reactors. The Wyoming plant is being constructed close to a retiring coal energy plant and is about to provide power to PacifiCorp, a utility firm that has relied on the coal plant.

Like Oklo’s design, TerraPower’s reactors could have “passive” security mechanisms in-built, the corporate says. This means they’re designed to robotically calm down if one thing goes fallacious, enabling them to keep away from the sorts of catastrophes related to the business, just like the 1986 Chernobyl accident.
Gates has mentioned he based — and invested greater than $1 billion into — TerraPower as a result of he believes increasing nuclear vitality technology is important to fight local weather change.
“This is a big step toward safe, abundant, zero-carbon energy,” Gates mentioned on the Wyoming plant’s groundbreaking ceremony in June. “It’s important for the future of this country that projects like this succeed.”
But TerraPower and different nuclear startups nonetheless have a way to go in convincing the general public that their next-generation designs aren’t simply possible, however also protected.
“The industry has been pushing for loosening regulations, speeding up processes, and the Trump administration undoubtedly will try to speed things up and reduce some regulations,” Squassoni mentioned.
Gates commented on nuclear security considerations in a June interview with NPR, saying the corporate welcomes regulatory scrutiny. “The Nuclear Regulatory Commission is the best in the world, and they’ll question us and challenge us. And, you know, that’s fantastic,” he mentioned.
