Oklo Inc. is an American advanced nuclear technology company that designs, builds, and plans to operate small fast fission power plants. Rather than selling reactors outright, Oklo’s business model is built around owning and running its plants and selling the electricity and heat they produce directly to customers under long term power agreements, similar to how a utility or independent power producer operates.

The company’s core technology, known as the Aurora powerhouse, is a compact sodium cooled fast reactor that can run on fresh, recycled, or down blended nuclear fuel, including high assay low enriched uranium known as HALEU. Because fast reactors like Aurora can use a wider variety of fuel types, including material recycled from used nuclear fuel, Oklo also positions itself as a nuclear fuel recycling company, not just a power plant developer.

Oklo has become closely associated with the surge of investor interest in nuclear energy driven by the electricity demands of artificial intelligence data centers. Data center operators need constant, round the clock power that does not depend on weather, and advanced nuclear reactors are frequently discussed as one possible long term solution alongside natural gas, solar, wind, and battery storage.

Oklo traces its roots to 2013, when Jacob DeWitte and Caroline Cochran, two nuclear engineers who met while studying at the Massachusetts Institute of Technology, founded the company to commercialize compact fast reactor technology. The design philosophy borrows heavily from the Experimental Breeder Reactor II, a sodium cooled fast reactor that operated for decades at what is now Idaho National Laboratory and demonstrated key safety and fuel recycling concepts that Oklo has since built upon.

In its early years, Oklo operated as a private startup, securing a site use permit from the U.S. Department of Energy, receiving an award of fuel material from Idaho National Laboratory, and submitting the first ever custom combined license application for an advanced fission reactor to the Nuclear Regulatory Commission.

The company’s path to the public markets began on July 11, 2023, when Oklo announced a definitive agreement to merge with AltC Acquisition Corp, a special purpose acquisition company co founded by OpenAI chief executive Sam Altman and investment banker Michael Klein. After a shareholder vote in May 2024 in which almost all votes cast approved the deal, the merger closed on May 9, 2024, and Oklo began trading on the New York Stock Exchange under the ticker OKLO the following day. The transaction delivered roughly 306 million dollars in gross proceeds to fund Oklo’s early stage plans.

Since going public, Oklo has expanded quickly through partnerships and acquisitions, including the purchase of Atomic Alchemy to build out a radioisotope production business, the acquisition of Creative Engineers to add chemical process engineering capability, and the purchase of ARMEC. The company has also signed agreements and letters of intent with data center and industrial companies such as Equinix, Switch, and Diamondback Energy, and has pursued fuel supply partnerships with Centrus Energy and Standard Nuclear.

Oklo was co founded by Jacob DeWitte and Caroline Cochran, a married couple with backgrounds in nuclear science and engineering from the Massachusetts Institute of Technology. Both founders remain deeply involved in running the company today, with DeWitte serving as Chief Executive Officer and Cochran serving as Chief Operating Officer.

According to ownership research, the founders continue to hold a significant combined stake in Oklo following the SPAC merger, and both are regularly featured in the company’s earnings calls, investor presentations, and media appearances discussing Oklo’s technology and business strategy.

OpenAI co founder Sam Altman also played an important early role in Oklo’s history as a public company. Altman and Michael Klein formed AltC Acquisition Corp in 2021, and after AltC merged with Oklo in 2024, Altman served as Chairman of Oklo’s board of directors. He stepped down from that role in April 2025, a move the company said was intended to avoid a potential conflict of interest as Oklo explored possible power supply partnerships with major artificial intelligence companies, including OpenAI.

Jacob DeWitte has served as Oklo’s Chief Executive Officer since he co founded the company in 2013. Before starting Oklo, DeWitte worked at the U.S. Department of Energy’s Idaho National Laboratory, where he was exposed to fast reactor research and the legacy of the Experimental Breeder Reactor II program that heavily influenced Oklo’s reactor design.

As CEO, DeWitte leads Oklo’s strategic direction, regulatory engagement with the Nuclear Regulatory Commission and Department of Energy, and commercial partnerships with data center operators, industrial customers, and government agencies. He regularly appears on Oklo’s quarterly earnings calls alongside the company’s Chief Financial Officer to discuss business progress, licensing milestones, and financial results.

Oklo is headquartered in Santa Clara, California, placing it in the heart of Silicon Valley alongside many of the technology companies that are now major potential customers for nuclear generated electricity to power data centers. The company also has significant operations and testing activity at Idaho National Laboratory in Idaho, where its planned Aurora powerhouse and Groves Isotope Test Reactor projects are located, reflecting its close working relationship with the Department of Energy’s national laboratory system.

Oklo organizes its business around three related units that all draw on the company’s nuclear engineering and fuel handling expertise.

Management has described these three units as complementary tracks that share underlying nuclear infrastructure, engineering talent, and regulatory relationships, which the company argues gives it more than one path to revenue as each business matures at its own pace.

Oklo’s flagship product is the Aurora powerhouse, a compact liquid metal fast reactor designed to generate around 75 megawatts of electricity in its initial configuration, with plans to scale the design to larger outputs for bigger customers over time. The Aurora design is intended to run for years between refueling, require a small physical footprint compared to conventional nuclear plants, and operate on a variety of fuel types, including recycled nuclear material.

Beyond electricity generation, Oklo’s product and service lines include:

• Long term power purchase style agreements that let customers buy electricity and heat output from an Oklo owned and operated plant rather than purchasing a reactor outright.
• Nuclear fuel recycling and fabrication services aimed at reducing dependence on foreign sources of enriched uranium.
• Radioisotope production for use in medical imaging, cancer treatment research, and industrial applications.
• Engineering and technical services gained through acquisitions such as Creative Engineers, which supports chemical process work tied to fuel and isotope operations.

Oklo has announced a substantial pipeline of customer interest, including a widely cited agreement framework with data center company Switch for up to 12 gigawatts of potential power capacity over time, along with letters of intent and partnerships involving Equinix, Diamondback Energy, Centrus Energy, Standard Nuclear, and a research collaboration with Nvidia and Los Alamos National Laboratory focused on applying artificial intelligence tools to nuclear engineering and fuel design.

Oklo is a pre revenue company. As of its most recently reported quarter, the company recorded zero dollars in revenue, matching analyst estimates of zero for that period. This means Oklo currently earns no income from selling electricity, fuel, or isotopes, and its stock valuation is based entirely on investor expectations about future commercial deployment rather than current sales or profit.

Management has stated that meaningful revenue is expected to begin once the first Aurora powerhouse units and the Groves Isotope Test Reactor become operational and start delivering power or isotopes under contract. Because the company has multiple business lines, future revenue is expected to eventually come from a mix of long term power sales agreements, fuel recycling and fabrication contracts, and radioisotope sales, though the exact timing and mix will depend on regulatory approvals and construction schedules.

Because Oklo has no current revenue to break down by segment, the chart below instead illustrates the company’s near term cash spending plans by category, which gives investors a sense of where capital is being deployed while the business builds toward commercial operation.

Oklo’s most recent quarterly report, covering the first quarter of 2026 and released on May 12, 2026, showed the company continuing to invest heavily while generating no revenue.

The company’s net loss widened compared with the prior year period as spending increased across reactor licensing, engineering, fuel research, and early construction activity, including groundbreaking work at Idaho National Laboratory and progress on a large planned power campus in Ohio. Despite the wider loss, Oklo ended the quarter with a strong cash position after raising additional capital through an at the market equity program, giving the company a multi year runway to fund development without needing revenue in the near term.

Trailing twelve month earnings per share stood at approximately negative 0.83 dollars, and the stock carries a negative price to earnings ratio because the company is not yet profitable, which is typical for early stage development companies in capital intensive industries such as nuclear energy, biotechnology, and semiconductor manufacturing.

Oklo trades on the New York Stock Exchange under the ticker symbol OKLO. The stock has been one of the more volatile names in the nuclear energy and broader clean power sector since its 2024 public debut, reflecting both rapid swings in enthusiasm for nuclear powered artificial intelligence infrastructure and the inherent uncertainty of a pre revenue company.

OKLO is also known for a high beta, meaning its price tends to move more sharply than the broader stock market, and reported trading volumes have often run well above ten million shares per day. Investors should note that some data providers report insider transactions have consisted largely of routine sales rather than purchases over the past several months, which is common at newly public companies as early employees and executives diversify holdings, but is still worth factoring into any research.

Oklo does not currently pay a dividend, and its dividend yield is listed as zero across major financial data platforms. This is expected for a pre revenue, capital intensive development stage company that is spending hundreds of millions of dollars per year on construction, licensing, and research rather than generating free cash flow.

Investors interested in OKLO are generally seeking capital appreciation tied to the long term success of the company’s nuclear power and fuel businesses rather than income. A dividend would only become realistic after Oklo’s power plants and other business lines are generating consistent, positive cash flow, which based on current company guidance and construction timelines would not be expected for several years at the earliest.

Oklo competes in the broader advanced nuclear and small modular reactor space, which includes both publicly traded and privately held companies pursuing different reactor designs and business models.

Beyond direct nuclear competitors, Oklo also indirectly competes with natural gas, solar, wind, and battery storage companies that are all vying to supply reliable power to the same data center and industrial customers.
