Key Takeaways:
The artificial intelligence boom has turned the utilities sector from a sleepy income play into one of 2026's top-performing trades.
The Tortoise AI Infrastructure ETF (TCAI) has surged 77.7% year to date, making it the top-performing utilities-focused fund as hyperscalers pour billions into data center construction. The fund tracks companies providing power infrastructure for AI workloads, from electric utilities to grid equipment manufacturers.
"The evolution of the AI trade breathed new life into the once-sleepy utilities sector," said Lucas Herrera, energy analyst at Edgen. "It was once seen as a boring bond-like group for risk-averse income investors. Now it's a growth story tied directly to data center electricity demand."
The shift reflects a structural change in US power markets. Data center electricity consumption is projected to more than double by 2030, according to industry estimates, as companies including Microsoft, Amazon and Alphabet build out AI computing capacity. That demand has lifted utilities that were previously viewed as low-beta defensive holdings.
The broader sector has followed TCAI higher. The Vanguard Utilities ETF (VPU) has returned 6.84% year to date, while the Utilities Select Sector SPDR Fund (XLU) has also gained. Both funds hold traditional regulated utilities that are signing long-term power purchase agreements with hyperscalers.
Data Center Demand Reshapes Utility Economics
The AI infrastructure buildout has created a new revenue stream for utilities. Regulated power companies are filing rate cases tied to data center interconnection agreements, while unregulated independent power producers are signing direct contracts with tech companies.
The trend extends beyond pure-play utilities. The Global X MLP & Energy Infrastructure ETF (MLPX), which holds 98% energy-sector assets including pipeline operators, has returned 23.2% over the past 12 months and yields 4.10%. The First Trust North American Energy Infrastructure Fund (EMLP), with 54% allocated to utilities, has returned 19.5% over the same period with a 2.80% yield.
What's at Stake for Investors
The utilities sector's transformation carries implications for portfolio construction. With the S&P 500 up 9.6% in the first half of 2026 and the Nasdaq gaining more than 12%, investors seeking diversification from concentrated tech exposure are turning to power infrastructure as a proxy for AI growth without direct equity risk.
The Federal Reserve held rates at 3.50%-3.75% in June, and new Chair Kevin Warsh has signaled a hawkish bias. Higher-for-longer rates typically pressure utility stocks, but data center demand is offsetting that headwind. Investors will watch second-quarter earnings in coming weeks for updated power purchase agreement disclosures and capex guidance from major utilities.
