Oklo Inc. and Centrus Energy Corp. have signed definitive, multi-year high-assay low-enriched uranium (HALEU) purchase agreements, formalising a letter of intent announced in June 2026 and giving the first phase of Oklo's planned Ohio campus a contracted fuel supply.
The contracts cover enough HALEU to run up to five of Oklo's Aurora powerhouses for several years. Deliveries are scheduled to begin in 2029 from Centrus's American Centrifuge Plant in Pike County, Ohio — the same state where the reactors will operate.
Prepayments become enrichment capital
Under the agreements, Oklo will make meaningful prepayments to Centrus for future fuel deliveries — money Centrus will use to help fund construction of new U.S. uranium enrichment capacity and to accelerate its commercial centrifuge manufacturing buildout. The structure turns a reactor developer into an early financier of the fuel cycle it depends on, a model becoming central to HALEU commercialisation, where demand must be bankable before supply can be financed.
Centrus said the definitive agreements demonstrate it is positioned to meet "substantial upcoming commercial demand" for HALEU, and that Oklo's prepayments, which add to others previously received, will help fund the buildout as the company scales its American Centrifuge technology and qualified manufacturing processes for commercial production.
Meta's prepayment reaches the fuel chain
The fuel purchase is indirectly supported by Meta Platforms, which previously agreed to prepay Oklo for future electricity. Power from the southern Ohio site will be sold into the PJM grid to serve Meta's data centre operations, meaning hyperscaler capital is now flowing two links down the chain — from electricity offtake to uranium enrichment.
What the fuel actually supplies
The HALEU will run the first phase of Oklo's planned 1.2 GW power campus in Ohio, support future Aurora projects, and eventually refuel Aurora-INL, Oklo's first reactor in Idaho, which initially runs on HALEU recovered from Experimental Breeder Reactor II fuel.
Oklo CEO Jacob DeWitte has framed fuel security as the gating item for scaling beyond the first reactor. For Centrus, the deal adds to a customer book now standing at USD 5.4 billion in contracts and commitments for LEU and HALEU from its new capacity — a figure that gives lenders and investors a demand signal well ahead of first commercial HALEU deliveries in 2029.
