How Cathie Wood's AI Infrastructure Forecast Signals Three Compelling Stock Opportunities in 2026

The artificial intelligence revolution is reshaping how capital flows through technology sectors. Cathie Wood and her Ark Invest research team have turned their analytical lens toward a critical but often overlooked segment: the infrastructure layer. Their projection that spending on AI data centers will surge from approximately $500 billion last year to reach $1.4 trillion by 2030 represents an annualized growth trajectory exceeding 20% — a pace that mirrors assessments from major financial institutions including JPMorgan. This expansion creates a distinctive investment landscape where three specific companies stand to capture meaningful value from the industry’s structural transformation.

The Market Backdrop: Why Infrastructure Takes Center Stage

The computational demands of artificial intelligence systems have outpaced the infrastructure built to support them. While semiconductor manufacturers like Nvidia have delivered extraordinary returns for early investors, the next wave of AI-driven wealth creation appears poised to flow toward the companies constructing and maintaining the physical systems that house these computations. Cathie Wood’s analysis suggests that buildout requirements will continue accelerating through the end of this decade, shifting focus from hardware manufacturers to infrastructure specialists facing genuine technical challenges their solutions must address.

This investment thesis rests on practical constraints. Existing data center designs weren’t engineered to manage the heat densities produced by AI workloads. As processors become more powerful and densely configured, thermal management has shifted from a routine maintenance consideration to a mission-critical engineering problem. Market research from Global Market Insights and Precedence Research indicates the worldwide data center cooling sector alone will expand at more than 10% annually through 2034 — a compound growth rate that highlights the urgency of this transition.

Addressing Tomorrow’s Infrastructure Bottlenecks: Vertiv’s Cooling Solutions

Vertiv (NYSE: VRT) represents one of the purest plays on this infrastructure buildout. The company operates across multiple technical domains, but its flagship business unit focuses on thermal management — particularly liquid-cooling architectures that represent the frontier of data center heat mitigation.

Conventional cooling approaches rely on air circulation and traditional HVAC systems, but modern AI data centers generate heat loads that these methods cannot adequately dissipate. Vertiv has responded by developing sophisticated direct-to-chip liquid cooling systems that pair with air-cooled components for maximum operational flexibility. The company’s recently introduced MegaMod HDX exemplifies this engineering approach, allowing data center operators to customize cooling configurations based on their specific workload profiles.

Beyond thermal solutions, Vertiv commands a substantial position in power management infrastructure. The business delivers battery storage systems, electrical distribution equipment, and backup power solutions that markets research projects will expand from under $9 billion annually today to surpassing $16 billion by 2035. Through the first nine months of 2025, Vertiv’s revenue climbed nearly 30% year-over-year, with profitability metrics more than doubling during the same span — performance that reflects the accelerating demand curve Cathie Wood’s team has identified.

Income and Stability: Digital Realty Trust’s Dual Investment Merit

Digital Realty Trust (NYSE: DLR) occupies a distinctly different niche within the AI infrastructure ecosystem. Rather than operating as a manufacturer or service provider, the company functions as a real estate investment trust — holding title to physical data center facilities and leasing capacity to operators worldwide.

This structural distinction carries meaningful implications. Digital Realty Trust maintains and operates more than 300 distinct facilities distributed across 50+ metropolitan areas, generating recurring revenue streams from over 250 Fortune 500 organizations. During the three-month period concluding in September 2025, the company generated approximately $1.6 billion in quarterly revenue, reflecting 10% year-over-year expansion and extending a two-decade streak of consecutive annual revenue growth.

The investment proposition extends beyond growth metrics. Digital Realty Trust’s status as a REIT mandates distribution of its taxable income to shareholders — creating a significant income component unusual in technology infrastructure plays. The company’s current forward dividend yield stands near 3.1%, providing immediate cash returns while retaining exposure to the secular infrastructure expansion that Cathie Wood and other institutional strategists have highlighted. For investors seeking both growth participation and regular portfolio income from the same holding, Digital Realty Trust presents an unusual combination.

High-Growth Potential With Volatility: Nebius and Emerging Opportunities

Nebius Group (NASDAQ: NBIS) delivers the purest exposure to AI infrastructure growth among the three candidates, but this directness comes coupled with meaningful volatility and execution risk. The company operates data center facilities purpose-built for AI workloads, positioning it as a more specialized player than its larger, more diversified competitors.

Nebius’ financial trajectory underscores both the growth opportunity and the associated challenges. During its third quarter 2025, revenue expanded 355% year-over-year to $146 million — a pace that validates the market demand thesis. However, the company’s bottom line has deteriorated rather than improved. Losses expanded from approximately $44 million in Q3 2024 to nearly $120 million in the three-month period ending September 2025, suggesting the company remains in an investment phase rather than approaching profitability.

Yet this apparent weakness contains important context. In September 2025, Nebius secured a transformational multibillion-dollar, multiyear contract with Microsoft to supply AI infrastructure services from its New Jersey facility. That Microsoft — possessing resources to build its own data center infrastructure or negotiate with any competitor — selected Nebius carries significant signal value regarding the company’s technical capabilities and competitiveness. The deal announcement initially drove shareholder enthusiasm, though recent share weakness has created what analysts covering the name predominantly view as an attractive entry point. The consensus analyst price target of $158.50 suggests approximately 70% upside from current levels, though prospective investors should acknowledge that Nebius will likely deliver higher price volatility than either Vertiv or Digital Realty Trust.

Evaluating Your Infrastructure Allocation

Each candidate addresses the AI infrastructure opportunity through distinct pathways. Vertiv offers operational execution and profitability visible in current financial metrics. Digital Realty Trust provides the combination of growth and dividend income. Nebius presents the highest-risk, highest-potential-reward profile backed by institutional validation from Microsoft’s partnership commitment.

The broader investment framework Cathie Wood and institutional strategists have articulated suggests that capturing this infrastructure expansion opportunity requires moving capital from late-cycle semiconductor investments toward the companies building and maintaining the computational foundation that will serve AI systems throughout this decade. The specific vehicles you select should reflect your risk tolerance, income requirements, and timeline for portfolio deployment.
