3 AI-Enabled Infrastructure Stocks to Buy and Hold for the Next Decade

The artificial intelligence revolution is accelerating, but its success hinges on a critical, often overlooked layer: the infrastructure that powers AI workloads. As demand for high-performance computing, data storage, and connectivity surges, companies enabling this infrastructure are poised for outsized gains. Among them, Applied Digital (APLD), Lumentum (LITE), and Marvell Technology (MRVL) stand out as undervalued enablers with robust fundamentals, strategic positioning, and long-term growth trajectories.

Applied Digital: The Powerhouse Behind AI Data Centers

Applied Digital has emerged as a linchpin in the AI infrastructure ecosystem by specializing in high-power, liquid-cooled data centers tailored for hyperscalers. Its recent 15-year, $7 billion contract with CoreWeave for a 250-megawatt campus in North Dakota underscores its critical role in meeting the energy demands of AI training and inference workloads. This long-term visibility has already driven a 37.9% expected revenue increase for fiscal 2026, with analysts projecting 30.4% revenue growth and 61.3% earnings growth for the same period.

What sets APLD apart is its ability to compress construction timelines from 24 months to 12–14 months, enabling rapid scalability as demand surges. With AI-driven workloads expected to dominate hyperscaler budgets for the next decade, Applied Digital's infrastructure is not just a short-term play but a foundational asset for the AI era.

Lumentum: The Photonics Enabler for AI Networking

Lumentum's optical and photonic technologies are indispensable for high-speed data transmission in AI infrastructure. As AI models grow in complexity, the need for low-latency, high-bandwidth networking solutions has skyrocketed. Lumentum's partnerships with industry leaders like NVIDIA position it as a key supplier of silicon photonics and AI networking components.

Recent financials highlight its momentum: LITE reported $533.8 million in revenue for its latest quarter, with $4.2 million in net income, while investing $81.4 million in R&D to maintain its edge. Analysts project 56% revenue growth in 2026 and 31.4% in 2027, driven by AI and telecom demand. Rosenblatt Securities' Mike Genovese recently raised LITE's price target to $380, citing its strategic relevance in the AI infrastructure value chain.

Marvell Technology: Semiconductor Solutions for AI Connectivity

Marvell's Q4 2025 results revealed a 27% year-over-year revenue increase to $1.817 billion, with data center revenue surging 78% due to demand for high-speed connectivity solutions. This momentum continued into Q3 2026, where revenue hit $2.1 billion, a 37% year-over-year jump, and non-GAAP earnings rose 77% to $0.76 per share according to reports.

The company's strategic acquisition of Celestial AI-a developer of AI inference accelerators-positions it to capitalize on the next phase of AI adoption, with revenue contributions expected from late 2028 according to financial reports. Marvell's operational efficiencies and favorable product mix have also driven improved gross margins, while its Zacks Rank of 1 and Momentum Score of A signal strong earnings growth potential according to market analysis.

Why These Stocks Deserve a Decade-Long Hold

Applied Digital, Lumentum, and Marvell represent three pillars of AI infrastructure: physical data centers, optical networking, and semiconductor connectivity. Their long-term contracts, R&D investments, and strategic acquisitions ensure they remain indispensable as AI adoption scales. With AI-driven workloads projected to dominate global data center demand for years to come, these companies offer a compelling combination of visibility, growth, and resilience.

For investors seeking undervalued, long-term holdings, the time to act is now-before the AI infrastructure boom fully materializes.
