Artificial intelligence workloads are pulling forward a decade of electricity demand growth, and nuclear power is emerging as the always-on backbone hyperscalers actually want to buy. The Department of Energy projects data centers will account for up to 12% of U.S. electrical demand by 2028, and Constellation’s own CEO has told investors that "projected spending levels for 2026 are nearly 75% higher than last year and continue to be revised upward" from hyperscaler customers. That is the setup heading into August.
Here are three US-listed operators with the reactor fleets, gas backup, and signed hyperscaler contracts to monetize that surge. Each pick is thesis-driven, not a trade instruction. Read them as research candidates for anyone building a nuclear-plus-AI power basket.
Constellation Energy (CEG): The Purest Nuclear-AI Play
Constellation Energy (NASDAQ:CEG | CEG Price Prediction) runs the largest US nuclear fleet and is the clearest listed vehicle for pricing hyperscaler power appetite. Shares closed at $282.50 on August 14, giving the stock a market cap of roughly $98.7 billion and a forward P/E near 23. The stock has climbed 9.45% over the past month, even as it sits -19.8% year to date after a huge 2025 run.
The bull case tightened on the Q2 report. Constellation posted adjusted EPS of $2.55 versus a $2.33 estimate and raised FY2026 adjusted EPS guidance to $11.50 to $12.50. The nuclear fleet delivered 44,160 GWh at a 93% capacity factor in Q2. More important for the AI thesis: management signed 920 MW of long-term nuclear PPAs (15 to 20 years) with investment-grade customers beginning 2029 to 2032, and the Crane Clean Energy Center restart is targeting 2027. Wall Street is aligned, with 20 buy or strong buy ratings against 3 holds and an average target of $349.96.
Risk to watch: The Q2 refueling schedule ran 86 outage days versus 41 the prior year, dropping operating income -39% YoY. Illinois’ ZEC program also ends May 2027, and PJM’s capacity market framework is still being finalized.
Vistra (VST): The NVIDIA-Backed Diversified Operator
Vistra (NYSE:VST) closed at $148.13 on August 14, up 5.36% over the past week after the Q2 report and Helix announcement. Forward P/E sits at just 16, and analyst sentiment is unusually one-sided with 19 buy or strong buy ratings and zero holds. The average price target is $221.74.
The headline catalyst is the Helix Digital Infrastructure JV with NVIDIA, KKR, and Kuwait Investment Authority, which designates Vistra as preferred power provider with an initial commitment of up to $1.0 billion. CEO Jim Burke framed the structure as a "rack-to-grid, one-stop-shop solution" for data center customers. Add Meta PPAs signed at the Comanche Peak twin-unit nuclear plant, FERC approval for the pending 5,500 MW Cogentrix gas acquisition, and Q2 Ongoing Ops Adjusted EBITDA of $1.77 billion (+30%+ YoY), and you get a nuclear-plus-gas fleet that hit 97%+ commercial availability during extreme heat. The company is hedged ~100% for 2026 and ~94% for 2027, locking in economics while the AI load ramp arrives.
Risk to watch: Q2 GAAP net income fell -6.73% YoY, hit by $472 million in unrealized MTM hedge losses. That volatility can distort headline earnings even when cash economics improve, and ERCOT forward curves are running meaningfully lower for 2027.
NextEra Energy (NEE): The Diversified Compounder With a Nuclear Restart
NextEra Energy (NYSE:NEE) is the largest name in the group at $179.4 billion market cap, and the only one delivering a real dividend yield alongside the AI story. Shares closed at $86.19 on August 14, up 8.86% year to date and 22.75% over the past year. The dividend yield is 2.77% with committed growth of ~10% annually through 2026, then 6% through 2028.
Q2 delivered adjusted EPS of $1.15 versus $1.10 estimate, the fifth straight beat. The AI pipeline is enormous: FPL has ~21 GW of large-load interest, with 12 GW in advanced discussions. CEO John Ketchum told investors that "every gigawatt of large load under FPL’s approved tariff [is] equivalent to roughly $2 billion of capex". The Duane Arnold nuclear restart is on track for no later than Q1 2029, and the proposed Dominion Energy merger is targeted to close in H2 2027. Management is guiding to 8%+ adjusted EPS CAGR through 2032, then 9%+ through 2035 assuming the Dominion combination closes.
Risk to watch: The Dominion merger has to clear Virginia, North Carolina, South Carolina, FERC, and NRC. Q2 revenue of $7.53 billion missed the $8.15 billion consensus, a reminder that top-line lumpiness happens even when adjusted EPS beats.
The Setup Into September
Each name plays the same theme differently. Constellation is the pure-fleet nuclear operator with hyperscaler PPAs already inked. Vistra pairs baseload nuclear with the fastest-growing gas platform and now has NVIDIA on its cap table via Helix. NextEra brings the biggest customer pipeline, a regulated Florida engine, and an active nuclear restart. Watch PJM’s capacity framework, the ERCOT queue thinning under Governor Abbott, and NextEra’s promised year-end large-load contract announcement. Those three catalysts will tell you whether the August rally in the group has more room to run.
