What Oklo does
Oklo Inc. is a pre-revenue advanced nuclear fission company founded in 2013 and headquartered in Santa Clara, California, that designs, builds, owns, and operates small modular fast fission power plants under a power purchase agreement (PPA) model. The company's flagship product, the Aurora Powerhouse, is a liquid-metal-cooled, metal-fueled sodium fast reactor producing up to 75 MWe of electric power with inherent passive safety, 10-20 year refueling intervals, and the ability to use recycled nuclear fuel including surplus plutonium. The technology is based on demonstrated fast reactor designs with over 400 reactor-years of global operating experience, supported by EBR-II fuel access and ongoing partnerships with Idaho National Laboratory, Los Alamos National Laboratory, and NVIDIA via the Prometheus AI platform for design and simulation acceleration.
Oklo operates across three integrated business lines: power generation (Aurora powerhouses), fuel recycling and fabrication (Aurora Fuel Fabrication Facility at INL and a $1.68 billion advanced fuel center under development in Oak Ridge, Tennessee), and isotope production (Atomic Alchemy subsidiary, Groves Isotope Test Reactor in Texas targeting July 2026 criticality). The build-own-operate model sells electricity directly via long-term, multi-year PPAs to data centers and hyperscalers (Meta 1.2 GW Ohio campus, Switch 12 GW, Equinix 500 MW with $25M prepayment), industrial sites, defense facilities (U.S. DOE and DOD), and communities, with no capital outlay required from customers. Customer prepayments are used to fund development and fuel procurement.
The company is publicly traded on NYSE under ticker OKLO following a May 2024 SPAC merger with AltC Acquisition Corp at a $13.9 billion post-money valuation, raising approximately $850 million pre-merger. Subsequent capital activity included a $1.18 billion at-the-market equity offering in Q1 2026 leaving the company with $2.5 billion in cash, with trailing 12-month net losses of $129 million. First commercial power is targeted for late 2027 or early 2028, with Guggenheim modeling a build path from 75 MW online in Q4 2027 to 1.1 GW by 2032. Key risks remain regulatory execution, fuel supply chain (HALEU via Centrus Energy), and dilution given the capital-intensive nature of the build.

Product overview
Oklo is a fission technology company deploying power plants to provide clean, reliable, and affordable energy. The company operates across three integrated business units: Power (Aurora Powerhouse fast fission reactors up to 75 MWe), Fuel (nuclear fuel recycling and fabrication including the Aurora Fuel Fabrication Facility and Oak Ridge recycling facility), and Isotopes (medical and industrial isotope production via the Groves Isotope Test Reactor and Idaho Radioisotopes Laboratory). Oklo's build-own-operate model sells power via PPAs directly to customers including data centers, factories, and industrial sites. The Pluto reactor and ARMEC acquisition support the company's broader advanced reactor and manufacturing capabilities.

Oklo competitors and assessment
Company assessmentDirect peers
- NuScale Power: Publicly traded (NYSE: SMR) designer of small modular reactors (light-water SMRs) targeting data center and utility customers. Most direct competitor to Oklo in the SMR space, pursuing similar hyperscaler/utility PPAs with a different reactor technology.
- TerraPower: Bill Gates-backed advanced nuclear developer building the Natrium sodium-cooled fast reactor in Wyoming. Closest direct competitor to Oklo's Aurora since both deploy Gen IV SFR technology targeting utility and industrial customers.
- X-energy: Developer of the Xe-100 high-temperature gas-cooled SMR backed by Amazon with a Washington state data center project. Directly competes for hyperscaler/data center 24/7 clean power contracts with a different advanced reactor architecture.
- Rolls-Royce SMR: UK-based SMR consortium developing a 470 MWe light-water small modular reactor. Competes directly for utility and data center SMR PPAs, particularly in Europe and Commonwealth markets where Oklo's newcleo partnership could overlap.
- GE Hitachi Nuclear Energy (BWRX-300): GE-Hitachi's BWRX-300 boiling water SMR is a leading competitor with deployment plans in Ontario and TVA. Directly competes with Oklo for utility-scale SMR contracts, particularly in North American markets.
- Holtec International (Holtec-160 SMR): Holtec is developing the Holtec-160 SMR, a small pressurized water reactor. Competes for industrial and utility SMR deployments, including potential projects at decommissioned nuclear sites that overlap with Oklo's industrial customer segment.
Emerging players
- Last Energy: Microreactor-focused company developing small pressurized water microreactors for industrial and data center customers. Overlaps with Oklo on the small-footprint, behind-the-meter nuclear value proposition.
- Westinghouse eVinci: Westinghouse's eVinci is a heat-pipe microreactor designed for remote, industrial, and off-grid applications. Comparable to Oklo Aurora in target use cases (small modular clean baseload power) but using different reactor technology.
Others
- Centrus Energy: HALEU enrichment supplier that signed an LOI to supply fuel to Oklo. Strategic enabler for Oklo's fuel chain; Centrus is the only commercial HALEU producer in the US, making it a critical supplier rather than a direct competitor, but its commercial scale-up could shape Oklo's deployment trajectory.
- BWX Technologies (BWXT): Specialty nuclear components manufacturer supporting advanced reactor developers and producing medical isotopes. Overlaps with Oklo's manufacturing and isotope business lines (Atomic Alchemy), making it a strategic supplier and adjacent peer rather than a direct SMR competitor.
