Why a 2026 S&P 500 Rally Is Likely-And How to Position for It

The S&P 500 is poised for a significant rally in 2026, with U.S. equities expected to outperform global counterparts as artificial intelligence (AI) investments and supportive policy frameworks drive market momentum. According to a report by the BlackRock Investment Institute, AI-related capital expenditures are projected to reach $5–$8 trillion through 2030, underpinning a structural shift in economic activity. This surge in AI-driven growth, coupled with a focus on earnings expansion rather than speculative valuation reflation, positions the market for a robust 14% gain in 2026. However, navigating this bull market requires strategic sector rotation and stock selection to capitalize on emerging opportunities while mitigating risks tied to overvalued tech stocks.

AI Infrastructure: From Software to Hardware

The AI narrative is evolving from speculative software development to the tangible infrastructure required to power it. High-performance computing (HPC) demand, data center expansion, and energy consumption are now central to the AI story. For instance, companies like NVIDIA (NASDAQ: NVDA) remain critical due to their dominance in AI chips, but the real long-term value lies in firms building the physical and digital ecosystems around AI.

Data center REITs such as Equinix (NASDAQ: EQIX) and Digital Realty (NYSE: DLR) are prime beneficiaries of this trend. These firms offer stable cash flows through long-term leases with tech giants and hyperscalers, making them attractive for investors seeking income and growth. A strategic vehicle like the Global X Data Center & Digital Infrastructure ETF (NASDAQ: VPN) provides diversified exposure to this sector. Meanwhile, hardware manufacturers and cooling technology providers are also gaining traction as data centers scale to meet AI's insatiable demand for processing power according to BlackRock's analysis.

Utilities: Powering the AI Revolution

The exponential growth of AI and data centers is driving a surge in electricity demand, with utilities positioned to benefit from this structural shift. According to Bank of America, utility stocks like Public Service Enterprise Group (PSEG), Alliant Energy (LNT), and Xcel Energy (XEL) are well-placed to capitalize on premium power contracts with tech firms. These companies are also investing in grid modernization and renewable energy infrastructure, aligning with broader decarbonization goals while ensuring reliable power supply for data centers.

The Utilities Select Sector SPDR Fund (NYSEARCA: XLU), with a yield of approximately 2.69%, offers a cost-effective way to access this sector. With the Federal Reserve maintaining interest rates in a neutral range of 3.00% to 3.25%, utilities' appeal as high-yield, stable-growth investments is further enhanced.

Healthcare: A Value-Driven Opportunity

As investors rotate out of overvalued tech stocks, healthcare emerges as a compelling alternative. The sector is currently trading at a historical discount relative to the S&P 500, creating a potential mean-reversion rally. The Health Care Select Sector SPDR Fund (NYSEARCA: XLV) provides exposure to a diversified basket of healthcare companies, from defensive players like UnitedHealth (NYSE: UNH) to innovative pharmaceutical firms such as Eli Lilly (NYSE: LLY).

M&A activity is also expected to accelerate in 2026, driven by cash-rich pharmaceutical companies seeking to replenish pipelines after patent expirations. This dynamic creates opportunities for both growth and value investors, particularly in biotech and specialty pharmaceuticals.

Strategic Sector Rotation and Diversification

The 2026 bull market is not confined to a single sector but spans AI infrastructure, utilities, and healthcare. A balanced approach that combines growth-oriented AI plays with defensive utilities and value-driven healthcare stocks can mitigate volatility while capturing multi-sector tailwinds. For instance, pairing high-growth data center REITs with high-yield utilities and undervalued healthcare ETFs creates a diversified portfolio aligned with both near-term AI-driven demand and long-term economic trends.

Moreover, the U.S. dollar's expected early 2026 weakness and subsequent rebound, alongside a government bond rally in the first half of the year, suggest a dynamic macro environment. Investors should remain agile, adjusting allocations based on central bank policy shifts and sector-specific momentum.

Conclusion

The 2026 S&P 500 rally is underpinned by AI's transformative impact on infrastructure, energy, and healthcare. By strategically rotating into sectors directly benefiting from AI-driven demand-such as data centers, utilities, and healthcare-investors can position themselves to outperform the broader market. A disciplined approach that balances growth, income, and value will be critical in navigating this bull market, ensuring resilience against macroeconomic headwinds while capitalizing on the AI revolution.
