Range Nuclear Renaissance Index ETF (NUKZ) targets reactor operators and SMR developers with 42% one-year returns, Global X Uranium ETF (URA) tracks uranium miners up 62% over 12 months amid upstream fuel constraints, and VanEck Uranium and Nuclear ETF (NLR) blends utilities with miners for conservative 37% one-year gains.
Data centers will consume up to 12% of U.S. electricity by 2028, and hyperscalers signing direct power purchase agreements with nuclear operators are driving restarts and small modular reactor commercialization across the supply chain.

Nuclear power has become the default answer to a question Wall Street did not expect to ask this decade: where will the electricity for AI come from? Hyperscalers are signing power purchase agreements directly with reactor operators, dormant plants are being recommissioned, and small modular reactor (SMR) developers are moving from PowerPoint to permitting.
Investors seeking exposure to the nuclear sector now have three distinct paths, each addressing a different segment of the supply chain. The Range Nuclear Renaissance Index ETF (NYSEARCA:NUKZ) focuses on infrastructure and reactor development. The Global X Uranium ETF (NYSEARCA:URA) provides access to the uranium fuel cycle. Finally, the (NYSEARCA:NLR) offers a defensive position through established utilities and grid operators.
Why nuclear, why now
The Department of Energy projects data centers will account for up to 12% of U.S. electrical demand by 2028, with Lawrence Berkeley National Laboratory estimating a range of 6.7% to 12% of total annual U.S. electricity consumption by 2028. A single hyperscale facility can draw over a gigawatt of power, equivalent to roughly 750,000 homes, and the load profile is steady around the clock, which is precisely what nuclear is designed to deliver.

S&P Global projects that data center power demand will roughly triple by 2030, accelerating discussions about reactor restarts at Three Mile Island for Microsoft and the Talen-Amazon arrangement at Susquehanna. The EIA flagged that residential electricity prices are expected to increase by 5% in 2026, prompting regulators to favor firm, dispatchable generation. Goldman Sachs Asset Management identified renewable energy, power grids, and energy storage as megatrend opportunities for 2026, and nuclear sits at the intersection of all three.
NUKZ: the cleanest reactor and SMR exposure
NUKZ is the youngest of the three but is most precisely aimed at the thesis. The Range Nuclear Renaissance Index targets companies whose revenue is directly tied to the construction, operation, and servicing of reactors, including SMR developers, fuel fabricators, and engineering specialists. Holdings cluster around Constellation Energy, BWX Technologies, and Cameco, capturing the operator, component manufacturer, and fuel supplier in a single basket.
NUKZ trades near $72, with a 14% year-to-date gain and a 42% one-year return, but this trails URA on the year but outpaces NLR, the right outcome for a fund weighted toward infrastructure rather than fuel or regulated utilities.
If SMR commercialization timelines slip, traditional reactor operators and large-cap engineering firms still benefit from restart contracts and license extensions. If SMRs scale, the fund already owns the manufacturers. The tradeoff is concentration risk, and with a relatively short holdings list dominated by a handful of names, a single bad quarter from Constellation or BWX could pull the whole fund down more than a broader sector ETF would absorb.

URA: the uranium fuel chokepoint
URA owns the upstream side, as the Global X Uranium ETF tracks the Solactive Global Uranium & Nuclear Components Total Return Index, with portfolio weight historically concentrated in pure-play uranium miners (Cameco, Kazatomprom) and the Sprott Physical Uranium Trust. The expense ratio is 0.69%, in line with thematic peers.
URA is up 19% year-to-date and 62% over the past 12 months, reflecting both the spot uranium move and the contract pricing reset flowing through to miners' economics. Over five years, URA has returned 184%, and over ten years, 416%, the highest of the three on both windows.
Western utilities spent the 2010s running down strategic uranium inventories, and Kazakh, Canadian, and Australian production cannot ramp quickly. Every new reactor restart and every SMR contract pulls demand forward against a fuel pipeline that takes years to expand. When uranium spot prices correct, miners typically fall harder than utilities. URA showed that asymmetry recently, with a 6% one-month decline even as the broader thesis remained intact.
NLR: the utility and grid side of the trade
NLR is the most conservative way to own the theme, with the VanEck Uranium and Nuclear ETF blends regulated nuclear utilities with miners, plus a smaller allocation to SMR developers, giving it a cash-flow profile closer to that of a utility fund than a commodity vehicle. Top holdings have historically centered on operators such as Constellation Energy and Public Service Enterprise Group, as well as Cameco and select international utilities.
NLR trades near $133, with a 7% year-to-date return and a 37% one-year gain. Lower than URA and NUKZ, but with the rate base and regulated returns that come with utility exposure. Over ten years, the fund has returned ~270%, the longest verifiable track record of the three.
Utilities that sign direct PPAs with hyperscalers capture margin every time a data center plugs in, regardless of whether new reactors are built on schedule. Regulated utilities cannot rerate as aggressively as miners or pure-play developers. If uranium prices double again, NLR will lag. If SMR rollouts disappoint and the trade compresses into established utilities, NLR holds up better than either alternative.
Choosing between the three
The choice depends on what part of the thesis a reader finds most credible:
NUKZ for the reactor and SMR thesis directly. If the bet is that hyperscaler contracts and SMR commercialization drive the next leg, NUKZ is the most concentrated way to express that view without owning a single stock. Accept the concentration risk for the cleanest exposure.
URA for the fuel cycle squeeze. If uranium supply cannot keep up with demand pulled forward by restarts, life extensions, and new builds, URA captures that asymmetry. Expect higher volatility and a tighter link to spot pricing.
NLR for the utility and grid leg. If the goal is exposure to the theme with regulated cash flows and lower beta to uranium, NLR is the most defensive of the three and has the deepest historical record.
A reasonable approach for a diversified thematic position is owning more than one. NUKZ and URA together cover infrastructure and fuel without duplicating much utility exposure. NLR and URA together capture utilities and miners, but underweight the SMR and engineering names that NUKZ holds. The funds are complementary by design.
