Three AI Stocks With Long-Term Growth Potential Investors Are Watching Closely

AI Investing Still in Early Stages Despite Significant Hype

As artificial intelligence continues reshaping industries globally, growth-focused investors are zeroing in on companies positioned to benefit from what many analysts describe as a multi-decade technological shift. While AI has already generated substantial market enthusiasm, analysts argue the technology remains in its earliest stages — with agentic AI only beginning to find traction among businesses and consumers, and use cases extending far beyond the chatbots that dominate headlines.

Three companies in particular — Iren, Alphabet, and Broadcom — have drawn attention for their distinct roles in the expanding AI ecosystem.

Iren: Infrastructure-Heavy Bet on AI Compute Demand

Iren (NASDAQ: IREN) has been aggressively expanding its energy capacity to meet surging demand for AI computing infrastructure. Year to date, the company has more than doubled its total gigawatt capacity from 2.9 to 5.8 gigawatts — a significant operational milestone that positions it to serve more enterprise clients requiring large-scale AI compute.

One headline development: Iren recently secured a five-year agreement with Nvidia (NASDAQ: NVDA) valued at $3.4 billion for 60 megawatts of capacity — an average annual value of $11.3 million per megawatt. That deal signals growing institutional confidence in Iren's infrastructure capabilities.

Comparisons with peers like Nebius (NASDAQ: NBIS) and Cipher Mining (NASDAQ: CIFR) reveal a nuanced picture. While those companies have moved faster in locking down hyperscaler tenant agreements, Iren has expanded its physical infrastructure pipeline at a quicker pace. The company is borrowing heavily to finance Nvidia chip purchases and data center construction, betting that returns will materialize in the near term.

Iren also raised its projected annualized run rate revenue from $3.7 billion to $4.4 billion, suggesting the company anticipates meaningful top-line growth ahead. Performance indicators point to a company still in an investment-heavy phase, with results expected to follow.

Alphabet: Established Giant With AI Momentum

Alphabet (NASDAQ: GOOG, GOOGL) brings a different profile to the AI conversation — one built on decades of dominance in search advertising and a growing cloud computing division that is now a primary AI growth driver.

The company reported 22% year-over-year revenue growth in Q1 2026, powered by the high-margin contributions of Google Search and YouTube. More notably, Google Cloud posted 63% year-over-year growth in the same quarter, driven largely by enterprise AI demand. The segment now represents nearly 20% of Alphabet's total revenue.

CEO Sundar Pichai described AI investments as "lighting up every part of the business" — a characterization that aligns with the accelerating cloud figures. Alphabet is also channeling its substantial capital reserves into longer-horizon projects like autonomous vehicle brand Waymo and its Gemini AI model.

Analysts note that Alphabet's financial strength gives it unusual flexibility to absorb early-stage losses in new ventures while funding AI infrastructure at scale — a dynamic that proved critical in the decade-long path to Google Cloud profitability.

Broadcom: Custom Chip Maker Riding a 143% AI Revenue Surge

Broadcom (NASDAQ: AVGO) occupies a specialized niche in the AI semiconductor market, designing custom chips for specific technology clients rather than producing general-purpose processors. That specialization appears to be paying off at scale.

In its fiscal 2026 second quarter, Broadcom reported 48% year-over-year revenue growth overall, with AI-related revenue surging 143% year over year. AI chips now account for nearly half of the company's total sales — a proportion that data suggests will continue to grow.

Profitability metrics were equally striking. Net income nearly doubled year over year, producing a 42% net profit margin for the quarter — a figure that underscores the economic leverage in custom chip design.

Perhaps the most attention-grabbing recent development is Broadcom's newly unveiled custom AI chip for OpenAI, named Jalapeño. Described as an LLM-optimized inference chip, the product earned notable praise in an OpenAI press release, which stated the chip "delivers performance per watt substantially better than current state-of-the-art" in early testing.

What to Watch Going Forward

Each of these three companies operates at a different layer of the AI stack — infrastructure, platforms, and silicon — giving investors a range of exposure points to what many analysts characterize as a generational technology wave.

Key metrics worth monitoring include Iren's progress on hyperscaler tenant agreements, Alphabet's cloud growth trajectory, and Broadcom's ability to expand its custom chip client roster. As AI adoption accelerates across enterprise and consumer markets, the performance of these companies could offer meaningful insight into which parts of the AI value chain are capturing the most durable economics.
