AI-Led Power Surge Pushes Nuclear ETFs Higher as Uranium Funds See Inflows

AI-Led Power Surge Pushes Nuclear ETFs Higher as Uranium Funds See Inflows Data center electricity demand is projected to jump from 5% to 15% of US grid load in five years. The Global X Uranium ETF (URA) closed Monday (2026-06-22) at $46.95, down 1.30% on the session, but the broader narrative driving nuclear exposure remains intact.⁷ The fund holds $6.86 billion in assets and offers the deepest liquidity for traders seeking pure uranium-price exposure, a function of the sector's revival around AI data center power demand.⁷ US power generation from data centers is projected to climb from roughly 5% of the total to about 15% over a five-year span, representing a step change on a grid that has barely grown since 2000.⁷ That math has capital rotating into energy companies that can supply baseload power for AI buildouts, with nuclear and renewable generation offering the cleanest solutions, analysts at Quick Read Capital said in a May note (2026-05-21).¹ The bet is not abstract. Microsoft signed a 20-year, 835 MW power purchase agreement with Constellation Energy in September 2024 to restart Three Mile Island Unit 1, a $1.6 billion project now targeting a 2027 startup.⁷ A single 1 GW reactor occupies a fraction of the land of an equivalent solar build and runs at capacity factors north of 90%.⁷ Over the next 25 years, the US government wants to quadruple nuclear capacity from roughly 100 GW in 2024 to 400 GW by 2050.² Goldman Sachs reinforced the theme in a recent edition of its Global Reactor Tracker, noting that buildout momentum continues to broaden as small modular reactors move into the bankable project pipeline.⁶ Not all nuclear exposure looks the same. The Uranium & Nuclear ETF (URAN) offers unique exposure to Japanese and Korean reactor builders at a lower cost than competitors, according to a May analysis (2026-05-28).⁷ That matters as South Korea's defense ministry unveiled a roadmap in late May 2026 to achieve nuclear-powered submarines, signaling the government's deepening commitment to the technology across both military and civilian applications.⁸ The NUKZ ETF, a more concentrated play, has returned roughly 52% over the past year and about 11% year to date through late May, with shares near $71.⁷ The fund carries an expense ratio of 0.85% and roughly $841 million in assets, small but no longer micro.⁷ Its top weights have included Talen Energy at roughly 3% and Dominion Energy near 3%, alongside Cameco, GE Vernova, and Constellation.⁷ Yet the nuclear renaissance narrative sits alongside a less comfortable reality. Japan's heavy dependence on imported energy is being stress-tested by the closure of the Strait of Hormuz, with roughly 90% of its crude imports transiting the chokepoint.³ That has pushed coal back into the generation mix and puts upward pressure on JKM spot LNG, which traded flat at $15.31 on Monday (2026-06-22).³ A sustained Asian LNG rally could erode the cost competitiveness of gas-to-power switching, strengthening the case for new nuclear baseload in the region. One micro-cap illustration of the AI-power frenzy came from Fluence Energy. Shares closed at $24.16 on May 8, 2026, up 98.2% in a single week after the company disclosed master supply agreements with two hyperscalers and a record $5.6 billion backlog.¹ CEO Arun Narayanan said "the operational discipline and margin profile we established in 2025 are proving durable."¹ But shares remain down roughly 39% year to date, with stockholders' equity of -$265.88 million and cash of just $36.59 million.¹ The risk is balance-sheet stress for the companies racing to build. The near-term question for uranium ETF holders is whether the AI-driven demand thesis holds as the grid confronts interconnection queues, regulatory timelines and fuel-supply concentration. Russia dominates the cross-border business of nuclear fuel and technology, a geopolitical chokehold that Beijing is already seeking to exploit with its own generation of reactors.⁴ China's Shidaowan plant demonstrated in 2025 that a new reactor design can safely cool without pumps, a milestone that Beijing is now commercializing faster than US or European vendors.⁵ The clearest signal to watch is the pace of US project financing. If Three Mile Island's restart hits its 2027 target and other hyperscaler PPAs follow, the bull case for uranium exposure hardens. If permitting or fuel-supply bottlenecks emerge, the ETF inflows that have pushed NUKZ up 52% over the past year could reverse just as quickly.
