3 Australian AI Stocks To Own In September 2026

AI optimism recently lifted global stocks after the Nasdaq 100 moved close to its record high, and that enthusiasm is feeding straight into how investors look at Australian artificial intelligence opportunities. When capital chases anything linked to ChatGPT or large language models, mispricing can appear on both the chip and software side. This article walks through three underappreciated Australian AI stocks from our screener that many investors may be overlooking.

These underappreciated AI stocks are only a starting sample, as the full screen surfaced 0 more companies with equally compelling narratives that are not covered below. To identify and analyze the highest conviction ChatGPT and AI plays across chips, software and cloud, head straight into the Undervalued Artificial Intelligence/ AI Stocks screener.

COSOL (ASX:COS)

Overview: COSOL provides AI enabled enterprise asset management and data services, using machine learning to support maintenance, performance and analytics for asset heavy industries worldwide.

Operations: COSOL generates about A$54.9 million from Australian consulting, A$30.7 million from asset management services, and A$12.9 million from the Americas, mostly across Asia Pacific.

Market Cap: A$35.5 million

COSOL integrates AI and machine learning into asset management processes, including predictive maintenance and enterprise data integrity. The stock provides exposure to AI driven infrastructure and resources projects at a P/S of about 0.4x and is trading below one fair value estimate, while margins and earnings depend on how one unseen pressure develops.

That unseen pressure is exactly what the COSOL financial health report unpacks so you can see whether COSOL’s AI opportunity is being masked or fairly priced.

CAR Group (ASX:CAR)

Overview: CAR Group runs online automotive marketplaces and data services globally, using AI powered tools to support valuations, inspections and tailored advertising.

Operations: CAR Group generates about A$517.6 million from Australia, A$326.9 million from North America, A$252.9 million from Latin America, A$144.8 million from Asia and A$11.2 million from investments.

Market Cap: A$8.8 billion

CAR Group matters in this AI focused screen because its vehicle marketplaces are increasingly wired into proprietary data, machine learning and automation that help dealers price, inspect and present inventory more intelligently.

"Per-share compounding as Encar / webmotors / US non-auto scale; deleveraging (ND/EBITDA ~2.1x to lower) shifts EV to equity."

What really moves the needle for CAR Group is how one quietly evolving AI data engine affects pricing power and long term margin resilience.

That quiet shift makes CAR Group worth a closer look through the full narrative for CAR Group, where the full story of its AI engine and equity leverage comes into focus.

Ai-Media Technologies (ASX:AIM)

Operations: Ai-Media Technologies generates about A$60.2 million from internet software and services, with roughly A$41.4 million from North America and A$18.8 million across APAC and EMEA.

Market Cap: A$50.4 million

Ai-Media Technologies matters for this AI screener because its LEXI suite turns speech into captions, translations and searchable data using AI models, directly tying the business into how video content is processed for ChatGPT era platforms.

"The transition from human-in-the-loop services to an AI-native workflow with the LEXI suite and encoders is increasing the share of higher margin SaaS in the mix, which directly supports gross margin and EBITDA outcomes."

What really shapes the Ai-Media Technologies story now is how shifts in customer adoption speed could affect future margins and cash flow.

That adoption question is exactly what the full narrative for Ai-Media Technologies unpacks, showing where Ai-Media Technologies could be accelerating and where risks might be masking the real opportunity.
