The selloff in pre-revenue nuclear stocks is widening, with Oklo leading a 28% monthly decline that has erased nearly half the company's year-to-date value.
Oklo Inc. shares fell 9.6% to $41.31 on Thursday, extending a month-long slide that has wiped 28% from the stock and 42% year to date, as investors rotate out of speculative nuclear developers.
"The market is drawing a sharp line between pre-revenue reactor developers and profitable nuclear utilities," said Omar Tariq, energy analyst at Edgen. "Oklo and NuScale trade on milestones and sentiment, not earnings — and sentiment has shifted."
NuScale Power Corp. has dropped 23% over the same period, while Uranium Energy Corp. fell 18% in the past month and another 5% Thursday to $9.56. The VanEck Uranium and Nuclear ETF, which counts Oklo as its second-largest holding at 6.37% behind Cameco Corp.'s 23.46% weighting, declined 16% for the month and 4.4% on the day to $39.10.
The divergence tells the story: Constellation Energy Corp., which trades at 22 times earnings with $11.51 in EPS, fell just 2% over the past month. Vistra Corp. gained 5%. Oklo holds $275 million in cash but posted a $73.6 million net loss in fiscal 2024 and targets first commercial power no earlier than late 2027 — a timeline that leaves the stock exposed to sentiment swings with no revenue to anchor valuation.
Why Pre-Revenue Names Are Getting Hit Hardest
Oklo's slide has no single confirmed catalyst. The selloff reflects a broader de-rating of high-beta nuclear names as investors weigh missed milestone deadlines, regulatory uncertainty around NRC licensing, and insider selling — though those sales are frequently routine 10b5-1 plan transactions and not necessarily directional signals.
The company's bull case rests on a 12-gigawatt agreement with Switch and a $25 million pre-payment from Equinix Inc., signaling data-center demand for nuclear-powered AI infrastructure. But with zero revenue and a consensus analyst price target of $86.95 — more than double the current $41 stock price — the gap between narrative and financial reality has widened.
Profitable Utilities Hold Their Ground
The contrast with Constellation and Vistra highlights the market's preference for cash flow over promises. Constellation reaffirmed 2026 adjusted EPS guidance of $11 to $12, while Vistra reaffirmed adjusted EBITDA guidance of $6.8 billion to $7.6 billion and was recently upgraded to investment grade by Fitch Ratings.
For investors seeking nuclear exposure without single-stock risk, the VanEck Uranium and Nuclear ETF offers a diversified basket. But its 16% monthly decline shows that even broad-based funds are not immune to the sector's rotation.
The nuclear trade is splitting into two distinct narratives. Profitable utilities with real earnings and hyperscaler power-purchase agreements are holding value. Pre-revenue developers like Oklo and NuScale remain high-conviction bets on a 2027-2028 payoff timeline — but with no earnings to absorb shocks, position sizing matters. The next catalyst for Oklo will be its NRC licensing update, which could either restore confidence or deepen the selloff.
