Oklo is no longer only a paper reactor company. Days after the June quarter closed, the Groves isotope reactor in Texas reached first criticality on private land under Department of Energy safety oversight, moving from groundbreaking to a live core in a little over eleven months. That event is the cleanest evidence yet that the Santa Clara builder can take a full-scale nuclear system through procurement, construction, fuel load, and startup without waiting on a traditional utility customer. The investment debate is whether that speed transfers to Aurora, the commercial powerhouse still targeting a two thousand twenty-eight start at Idaho National Laboratory, before the build-own-operate model forces another round of equity.
The June print does not settle that debate. First-ever revenue arrived with two small June acquisitions, not with a watt of sold power, and the quarterly loss widened as research and overhead scaled with headcount. Cash and marketable securities finished near $3 billion after at-the-market sales that added more than twenty-three million shares in the first half. Management then lifted full-year cash-use and plant-and-equipment plans to pull procurement forward. After the May program finished selling about a billion of stock, a replacement authorization of the same size landed in September. The balance sheet bought time. It did not buy a commercial megawatt.
What the market is pricing is an option, not a utility. The Class A shares closed the eighteenth near $38, a capitalization of about $7 billion against a range that still stretches from the mid-thirties to just under one hundred ninety-four. Subtract the cash pile and the enterprise is closer to $4 billion for a platform whose offtake book is still mostly non-binding letters and a master agreement. The next year resolves three questions: whether Aurora-INL keeps its two thousand twenty-eight date, whether Meta and Switch convert into cash-backed power contracts, and whether fuel for the first cores is locked before the new ATM starts working in earnest.
