Profitable AI Stocks to Watch in October 2026

As AI workloads grow more demanding and public pushback against energy-intensive data centers rises, investors are shifting focus from speculative AI stocks to profitable companies with real earnings. This article highlights three AI-driven businesses currently generating strong revenue, each offering a unique perspective on the evolving AI landscape.

NVIDIA (NVDA) stands out as a prime example of a company successfully monetizing AI infrastructure spending. With a market value of around $5.6 trillion, NVIDIA generates most of its revenue from its Compute & Networking segment, which brings in approximately $275.4 billion. However, investors remain cautious about potential challenges, such as the emergence of an open-source alternative to NVIDIA's CUDA platform, which could erode its pricing power and market dominance.

Another key player, 2CRSI (ENXTPA:AL2SI), designs and builds GPU and AI servers, dense racks, and cooling systems. The company generated about €405 million in sales from components and finished products, but its slim profit margins of around 2% raise concerns about future sustainability, especially as AI infrastructure orders become more competitive.

eMemory Technology (TPEX:3529) focuses on embedded non-volatile memory and hardware security IP, generating NT$4.2 billion in sales. The company benefits from long product cycles in automotive, medical, and critical infrastructure sectors, which provide durable royalty streams. However, the stability of its royalty rates remains a critical factor in its financial performance.

These companies represent just a fraction of the 34 profitable AI players identified in the full screener, offering investors a range of opportunities to explore in the rapidly evolving AI market.
