The AI-power trade unwound hard, pulling GE Vernova and the merchant generators down double digits, while the regulated-utility anchor NextEra rallied on a safe-haven bid and its fresh record backlog.

The leader was NextEra Energy (NEE), up 4.6% to $81.90 on the regulated-power-and-generation chokepoint — the utility balance sheet that actually builds and owns the capacity the AI buildout needs. The gain had a fundamental spine: NextEra reported third-quarter results on October 21 with adjusted EPS of $1.24, ahead of consensus near $1.20, and lifted its Energy Resources backlog by 3.7 GW to a record 36.7 GW while reaffirming 8%-plus annual earnings growth through 2035. On Thursday's sharp risk-off tape — the Nasdaq Composite −2.60% to 26,008.86 against a Dow up 0.02% — that steady, dividend-paying profile drew the rotation out of high-beta AI names, and peer Public Service Enterprise Group (PEG) rose 2.4% to $72.72 alongside it.

The laggard was GE Vernova (GEV), down 10.6% to $827.42 on the grid-and-turbine chokepoint — the gas turbines, transformers and grid gear that gate how fast new generation can actually connect. There was no company print; GE Vernova reports Q3 on October 28. This was the "AI power" trade unwinding in sympathy with the broader AI-infrastructure selloff, and the merchant generators levered to datacenter demand led the decline: Vistra (VST) −9.8% to $140.83, Talen Energy (TLN) −7.8% to $331.42 and Constellation (CEG) −5.7% to $255.21. The split within the vertical was the story — the merchant, AI-exposed power names sold off while the regulated utility anchor caught a bid.

The nuclear-fuel rung, the front-end chokepoint of enrichment and uranium supply, fell with the risk-off tape: Cameco (CCJ) −3.8% to $78.93, Uranium Energy (UEC) −5.3% to $7.48, Denison (DNN) −7.3% to $2.16, NexGen (NXE) −5.0% to $8.10, Centrus (LEU) −4.4% to $104.15 and Energy Fuels (UUUU) −6.2%. The advanced-reactor rung was softer but more resilient: NuScale (SMR) −2.2% to $5.38 and Oklo (OKLO) −2.6% to $27.01 held up better than NANO Nuclear (NNE) −6.0% to $12.53 and BWX Technologies (BWXT) −5.8% to $127.30, with Curtiss-Wright (CW) −4.0% to $474.28. Huntington Ingalls (HII), the naval-reactor prime, bucked the tape at +1.8% to $278.86 on the same defense safe-haven bid lifting the broader primes.

The near calendar stays dense on the fuel and build-out side. GE Vernova's October 28 print is the immediate read on whether the power-equipment selloff is demand or beta, with Constellation, Vistra and Talen reporting in the same window. Further out, BWXT reports Q3 on November 2, NANO Nuclear on November 15, the NRC's 18-month review milestone on X-energy's Xe-100 construction permit falls December 16, and the Westinghouse/US-government definitive agreements are targeted to replace the binding term sheet by year-end. The fuel rung's reaction to those build-out dates, not the daily AI-power swings, is the structural variable to track.
