Reasons to Buy These 2 AI Stocks Offering Triple-Digit Returns in 2025

The artificial intelligence (AI) saga, supported by the massive growth of cloud computing and data centers, is yet to unfold fully. Solid demand from AI infrastructure end markets such as hyperscale automation, robotics, healthcare, energy, materials, financials and cybersecurity will dramatically change this space over the next five years.Here, we recommend two AI infrastructure developers that have skyrocketed in 2025 with more than 200% returns. Yet their diversified products for AI infrastructure and strong demand will ensure growth in the future. These two stocks are: Applied Digital Corp. APLD and Lumentum Holdings Inc. LITE. Each of our picks currently carries either a Zacks Rank #1 (Strong Buy) or 2 (Buy). You can see the complete list of today’s Zacks #1 Rank stocks here. The chart below shows the price performance of our two picks year to date.Image Source: Zacks Investment ResearchApplied Digital Corp.Zacks Rank #2 Applied Digital is a U.S. designer, developer, and operator of high-performance data centers for AI and blockchain workloads. APLD’s long-term prospects ride on accelerating spending on AI infrastructure by hyperscalers. The global AI market is expected to hit $500 billion by 2027. AI needs data centers with high power density, as well as changing power and cooling requirements. Hyperscalers require high-capacity data centers to meet the escalating power needs of AI and GPU-driven applications. These factors bode well for APLD’s prospects. Innovative Product PortfolioAPLD’s HPC pivot is anchored by multi-year leases at its Ellendale campus (Polaris Forge 1), which expanded from 250 MW in May 2025 to a fully leased 400 MW by August 2025 with a single hyperscaler tenant, CoreWeave Inc. CRWV. Management cites approximately $11 billion of anticipated contracted lease revenue across roughly 15 years.APLD targets 12-14 month build timelines, shortened from approximately 24 months previously, and is scaling to develop multiple campuses in parallel, with 700 MW under construction. Design features include direct-to-chip liquid cooling with a design PUE target of 1.18 and near-zero water use, leveraging over 200 days of natural cooling in the Dakotas. These capabilities, cited across 2025 and the first quarter of fiscal 2026, differentiate Applied Digital as data center power constraints tighten and hyperscaler demand accelerates. A proven design-and-deliver model, evidenced by recent fit-out activity and full campus leasing, increases the likelihood of repeat wins and schedule adherence as projects ramp.While the strategic focus is HPC, the Data Center Hosting business remains fully contracted at approximately 286 MW across two North Dakota sites and is operated at full capacity as of Aug. 31, 2025. The legacy hosting base offers operational continuity and cash generation support that can complement the staged conversion toward long-duration, hyperscaler-backed data center rental economics.Strong Estimate RevisionsApplied Digital has an expected revenue and earnings growth rate of 30.4% and 61.3%, respectively, for the current year (ending May 2026).
