Overview
Oklo Inc. is a U.S.-focused nuclear energy company developing small fast-fission power plants, branded Aurora, and commercializing nuclear-fuel recycling. Its designs are intended to produce 15–75 MWe using fresh, recycled, or down-blended fuel. The company also has an isotope business in development, including a radioisotope pilot plant in Texas. Oklo’s stated goal is to develop clean, reliable, affordable energy solutions at scale; it was founded in 2013.[1][2][3]
Its disclosed project activity is primarily in the United States, including an Aurora project at Idaho National Laboratory and the isotope pilot in Texas.[4][3] Oklo reported $1.21 million in revenue for the six months ended June 30, 2026.[5] Its latest employee figure located was 205 full-time employees across 33 U.S. states and two employees in Canada, as of December 31, 2025.[6] [1][2][3][4][5][6]
Products & services
Oklo’s planned Aurora powerhouse is a metal-fueled fast-fission reactor designed to generate 15–75 MWe using fresh, recycled, or down-blended nuclear fuel. The company describes embedded safety features and intends to sell electricity to customers under power-purchase agreements; expansion to 100 MWe or more is a potential future capability.[7][2][8]
Oklo is also developing fuel fabrication and recycling capabilities to turn used nuclear fuel and other nuclear materials into reactor fuel. Its reported work includes an end-to-end demonstration of key recycling-process stages and development of a fuel-fabrication facility at Idaho National Laboratory; commercial-scale recycling is a future goal, not an established scaled supply offering.[7][9][10]
Its isotope activities are intended to supply radioisotopes for medical, industrial, space, defense, and other applications. The Idaho Radiochemistry Laboratory is licensed to handle, process, and distribute radioactive materials, while the Groves Isotope Test Reactor is a low-power test reactor for validating production methods; it reached first criticality in August 2026. The company’s disclosures describe these as developing capabilities and do not state product-level revenue percentages.[11][12][13] [7][2][8][9][10][11][12][13]
Geographic presence
Oklo’s disclosed project and operating footprint is concentrated in the United States. Its locations include Idaho National Laboratory in Idaho, where the company is developing an Aurora powerhouse and operates a radiochemistry laboratory; Pike County, Ohio, the planned site of a 1.2-GW campus for Meta data centers; Oak Ridge, Tennessee, for a planned fuel-recycling facility; and Lockhart, Texas, for a planned isotope test reactor. These are project locations and should not be read as evidence that all facilities are operating.[4][14][15][3][13] Oklo also identifies a planned Aurora-Eielson project at Eielson Air Force Base in Alaska.[16]
The company’s 2025 annual report lists its principal executive office in Santa Clara, California, and describes other U.S. office subleases.[17][18] Its company overview lists offices in Santa Clara, Rockville, Maryland, and Brooklyn, New York; it does not provide employee counts by location.[19]
Oklo’s latest reported quarter in the available filings is the quarter ended June 30, 2026. Its filings do not provide a geographic revenue breakdown; reported revenue is not allocated by country or region, so regional sales shares cannot be determined from the disclosed figures.[20][21] [4][14][15][3][13][16][17][18][19][20][21][16][19]
Business segments
Oklo reports one operating and reportable segment. The CEO, as chief operating decision maker, reviews consolidated results and allocates resources across the company rather than distinguishing business activities as separate segments. Accordingly, the disclosed reportable segment represents 100% of segment revenue; for the six months ended June 30, 2026, consolidated revenue was $1.210 million.[22][23][24][5] [22][23][24][5]
Company history
Oklo was founded in July 2013 by Jacob DeWitte and Caroline Cochran. The company’s early focus was developing its Aurora advanced-fission power plant; it began pre-application work with the U.S. Nuclear Regulatory Commission (NRC) in 2016 and announced the Aurora concept and a Department of Energy (DOE) site-use permit for Idaho National Laboratory in 2019.[25][26][27]
Oklo submitted an Aurora combined-license application to the NRC in March 2020. The commission denied the application without prejudice in January 2022, citing insufficient information, while allowing that the company could reapply. In July 2023, Oklo agreed to combine with AltC Acquisition Corp.; the transaction closed in May 2024, and the company began trading on the New York Stock Exchange as Oklo Inc. that month.[28][29][30][31]
In 2024, Oklo expanded into radioisotopes through a collaboration with Atomic Alchemy and received DOE approval of the conceptual design for an Aurora fuel-fabrication facility at Idaho National Laboratory. It completed its acquisition of Atomic Alchemy in March 2025. Later in 2025, DOE selected Oklo projects for its Reactor Pilot Program, and Oklo and Los Alamos National Laboratory completed a fast-spectrum plutonium experiment. In 2026, the DOE-authorized Groves Isotope Test Reactor achieved first criticality; this was a test-reactor milestone, distinct from approval or operation of a commercial Aurora plant.[32][33][34][35][36][3][11] [35][36][3][11][25][26][27][28][29][30][31][32][33][34]
