Top 3 AI Penny Stocks To Watch In September 2026

AI is suddenly at the center of monetary policy debates, with US Federal Reserve officials explicitly linking stubborn inflation to demand for advanced computing power. When central bankers talk about data centers and chips, smaller AI-focused businesses are no longer a side story. That shift creates a window for investors hunting earlier stage AI opportunities. This article highlights three under-the-radar AI penny stocks from our screener that may warrant closer examination.

The three AI penny stocks covered below are only a small sample from our broader screen. This screen also surfaced 15 additional companies with equally compelling stories that are not included in this article.

If you want to go deeper into this opportunity, head straight to the AI Penny Stocks screener to analyze, compare, and identify the AI ideas that best match your own conviction.

SEERS (KOSDAQ:A458870)

Overview: SEERS develops AI-enabled medical monitoring systems that combine wearable biosensors, ECG Holter analysers, and clinical dashboards with more traditional medical hardware.

Market Cap: ₩974.3 billion

SEERS links directly to the AI Penny Stocks theme through medical AI algorithms that power real-time monitoring and diagnostics across its biosensors, ECG analysers, and ward dashboards, even though non-AI hardware still contributes to the product mix. Investors watching smaller AI players may find the stock interesting, depending on how one unseen pressure shapes the economics of those software driven deployments.

That hidden pressure point is exactly where margins and valuation could start to decouple, so review the DCF valuation analysis for SEERS before those economics fully reprice expectations.

S2W (KOSDAQ:A488280)

Overview: S2W builds AI driven data and cyber intelligence platforms, with SAIP’s tailored generative AI and tools like XARVIS and QUAXAR supporting user centric data operations and security.

Market Cap: ₩167.8 billion

S2W taps the AI Penny Stocks theme through SAIP, its generative AI engine for enterprise data operations, while cyber intelligence tools broaden its footprint. Forecasts indicate high earnings and revenue growth expectations. However, the stock carries a high P/S multiple and current losses, so much depends on how effectively SAIP and related AI platforms convert user traction into durable cash flows.

That conversion question is exactly what the 3 key rewards and 1 important warning sign unpacks so you can see where S2W’s AI potential might be masked or underestimated.

M31 Technology (TPEX:6643)

Overview: M31 Technology designs silicon IP and integration services that help chipmakers build AI accelerators and edge AI system on chips.

Operations: M31 Technology generates NT$1,715 million of revenue from semiconductor equipment and services across its silicon IP and design activities.

Market Cap: NT$21.3 billion

M31 Technology provides exposure to the AI Penny Stocks theme through silicon IP that powers custom AI accelerators and edge AI chips, while also operating a broader IP and services portfolio. The business has recently turned profitable, and the most important driver for margins and valuation still depends on one unresolved variable in future customer tape outs.

That single variable could be what the analysis report for M31 Technology reveals as the real swing factor for M31 Technology’s next chapter.
