Uranium ETFs Pull Back Despite $710 Billion AI Capex Signal as Nuclear Supply Lags
URA fell 1.60% on Friday as hyperscaler capital commitments reached record levels, with new reactor capacity not arriving at scale until the mid-2030s.
Global X Uranium ETF (URA) closed at $39.89 on Friday (2026-07-24), down 1.60% on the session, even as the demand rationale for nuclear power drew fresh support from the biggest technology spenders in the world. Microsoft, Meta, Amazon and Alphabet are collectively guiding to more than $710 billion in combined 2026 capital expenditure, with electricity supply increasingly shaping where data centers are built and at what cost, according to company guidance cited by finance.yahoo.com.5
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 the range at 6.7% to 12% of total annual U.S. electricity consumption. The EIA's 2026 annual energy outlook also models residential electricity prices rising 5% this year, pushing regulators toward firm, dispatchable generation options.4
But converting that demand into operating nuclear capacity is the problem. The IEA expects more than 70 gigawatts of new nuclear to come online by the mid-2030s — described in May 2026 (2026-05-28) by Forbes as one of the strongest pipelines in 30 years — without offering meaningful supply relief through the current decade. The gap between demand projections and buildout timelines has kept investors cautious even as the underlying thesis draws institutional attention.2
Constellation Energy (CEG), the dominant U.S. nuclear operator, had already fallen roughly 19% over the preceding month and 31% year to date as of mid-June (2026-06-12), according to finance.yahoo.com, alongside a strong first-quarter FY2026 print. Revenue of $11.122 billion beat consensus by 28% and grew 64% year over year, with adjusted EPS of $2.74 against a $2.60 estimate. Management reaffirmed full-year FY2026 adjusted operating EPS guidance of $11.00 to $12.00 and guided base earnings growth above 20% through 2029.5
CEO Joe Dominguez framed the commercial position directly: "America needs reliable, clean power and Constellation is built to meet this demand." The contracted book supports that claim. Constellation holds long-term power purchase agreements with Microsoft, Meta and CyrusOne, including a 380-megawatt deal signed at its Freestone facility in February 2026 with exclusivity rights over an additional 380 megawatts. The PJM Reliability Backstop Procurement framework is scheduled to open bilateral data center contracting from March 2027.5
The balance sheet offset is harder to dismiss. Long-term debt reached $17.5 billion following the Calpine acquisition, and the nuclear fleet capacity factor eased to 92% from 94% year over year. For a business priced on consistent baseload output, a two-point capacity erosion is not trivial. Calpine integration remains a live execution risk.5
Cameco (CCJ) dropped roughly 20% over the same period through mid-June (2026-06-12), putting the fuel supplier in similar drawdown territory to the operator despite their different revenue structures. URA, which offers the deepest liquidity and most concentrated uranium miner exposure among listed ETFs, posted 62% gains over 12 months through June 2026 before the more recent pressure, according to finance.yahoo.com.5,4
Among the ETF options, the Range Nuclear Renaissance Index ETF (NUKZ) returned 42% over one year by targeting reactor operators and SMR developers, while the VanEck Uranium and Nuclear ETF (NLR) delivered 133% over five years with a broader utility, miner and services mix. The Uranium and Nuclear ETF (URAN) offers exposure to Japanese and Korean reactor builders at lower cost than several competitors, according to reporting published on May 28, 2026 (2026-05-28) by AOL.4,3
Japan and South Korea are not clean exposures. Washington imposed sectoral tariffs of 25% on steel, aluminium and automobiles effective March and April 2026, then announced — before suspending for 90 days — reciprocal tariffs of 25% on Korean goods and 24% on Japanese goods. The IMF cut South Korea's 2026 growth forecast to 1% on April 22nd (2026-04-22), down from 2% in January, and trimmed Japan's growth projection by 0.5 percentage points. Economic drag in both countries is a headwind for any ETF running meaningful reactor-builder exposure.1
The March 2027 activation of the PJM bilateral contracting framework is the nearest hard date on the nuclear-to-data-center calendar. Constellation's ability to hold fleet capacity factors steady while absorbing Calpine and managing $17.5 billion in long-term debt is the price-setting variable as the broader nuclear trade positions ahead of that milestone.5
