SMR developers NuScale Power and Oklo saw stock gains as risk appetite returned to nuclear energy plays.
Risk appetite has returned to speculative, long-duration equities, with reactor developers leading the advance while the nuclear fuel complex remains largely unchanged. This divergence highlights the primary driver behind today’s movement in NuScale Power and Oklo.
⧉ Quick Read NuScale Power (SMR) and Oklo (OKLO) each jump 4% on risk-on sentiment, but both remain down 35% to 42% year to date. Uranium Energy (UEC) rises just 1% while the Global X Uranium ETF (URA) sits flat, confirming this is a positioning move, not a nuclear catalyst.

The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) rose 0.5% to $769.63 Thursday morning, marking a modest broad-market move that translated into outsized bounces in the highest-beta segments. NuScale Power (NYSE:SMR) advanced 4% to $9.65, while Oklo (NYSE:OKLO | OKLO Price Prediction) climbed 3% to $42.76. Both names rebounded after weeks of selling pressure, though neither trend was repaired by a single session. Through Wednesday’s close, NuScale Power had fallen 35% year to date, and Oklo had declined 42%.
Meanwhile, the fuel sector did not participate. Uranium Energy (NYSEAMERICAN:UEC) gained just 1% to $13.28, and the Global X Uranium ETF (NYSEARCA:URA) remained virtually unchanged at $48.03. This split between developer equities and the fuel complex defines today’s market action. No company announcements, contract awards, earnings releases, regulatory developments, or analyst rating changes have been verified for either NuScale Power or Oklo. Instead, the rally stems from a broader risk-on environment, bolstered by strong megacap technology earnings released Wednesday after the close, which lifted long-duration valuations across the market.
Because NuScale Power and Oklo are pre-revenue reactor developers whose commercial value lies years ahead, their shares exhibit heightened sensitivity to shifts in investor risk tolerance. This dynamic works both ways, as evidenced by their sharp sell-offs during softer sessions earlier in August. Today’s 4% gain reflects tactical positioning rather than a fundamental trend reversal. In contrast, Uranium Energy operates as a fuel producer with a fundamentally different business model, priced according to utility contract cycles and spot uranium markets. Consequently, a broad risk-on rally can lift developer stocks while leaving the fuel complex flat. A genuine nuclear sector catalyst would typically drive both segments higher simultaneously; the absence of such co-movement, confirmed by the stagnant Global X Uranium ETF, underscores the positioning nature of today’s trades.
The year-to-date performance further illustrates the disconnect. Through Wednesday’s close, Uranium Energy had risen 12% year to date, whereas NuScale Power and Oklo remained deeply negative. These companies do not trade as a unified basket, and investors should size their exposure accordingly.

Traders should monitor whether Thursday’s gains in NuScale Power and Oklo sustain into the afternoon, as risk-on rebounds in speculative equities frequently fade when the broader benchmark drifts. Investors should also watch for any regulatory updates or contract disclosures that could provide a fundamental anchor to the current move. Given the pronounced volatility profile and substantial year-to-date drawdowns, position sizing in the developer names should remain conservative. Uranium Energy belongs to a different category entirely, and combining the two only makes strategic sense when investors fully understand that they represent two distinct bets on the nuclear industry.
