CAR Group's Network Effect Faces Its AI Test, and Most Managers Are Betting It Holds

The online vehicle marketplace has been sold down as a feared AI casualty, but a growing group of managers argues AI will strengthen its moat, while a vocal minority says the multiple still leaves little margin for error.

The AI question at the heart of the thesis

No ASX stock has absorbed the AI disruption debate quite like CAR Group. Over the past year, fund managers have split into two camps: those who see the vehicle classifieds business as a marketplace whose value lies in an audience AI cannot easily replicate, and those who see enough uncertainty to step aside. By October, Auscap Asset Management was firmly in the first camp, saying it had been adding to its exposure throughout the year and arguing AI could actually strengthen CAR Group's moat.

Investors Mutual Limited opened a new position in the September quarter, saying it believes CAR Group has been unfairly marked down because of the potential for AI disruption. Ten Cap, by contrast, profited from a short position in September, arguing that “a full multiple leaves little room when the growth outlook is under question.”

Why managers say the moat is the audience

Auscap's September presentation laid out the reasoning in detail. CAR Group's moat, it said, is that it attracts all of the potential buyers, and therefore all of the sellers who want maximum exposure for their listings. Even if a better mousetrap emerged, Auscap said, “Our working assumption here is that car sales through AI will be able to replicate that better technology more quickly than it will lose audience.” Forager Funds made a similar point in March, arguing that carsales.com.au could be replicated technically for a few tens of millions of dollars, but that the value lies in a network effect built over decades and reinforced by scale.

Vertium Asset Management put it more bluntly in July. “I think it's very difficult to vibe code your way into that type of market,” the manager said, describing CAR Group as a marketplace that has been washed out alongside genuinely AI-exposed stocks. Investors Mutual added in July that CAR Group holds rich data on what consumers want to buy and what they are willing to pay, which large language models cannot compete with.

From threat to tool

A recurring theme in recent commentary is that AI is becoming a product advantage. Auscap reported that CAR Group has more than 200 developers in an AI hub in Brazil and has already demonstrated three applications: an agent that guides users through buying or selling a car, one-touch listings that identify a vehicle from a single photo then write and price the ad, and automatically generated 3D walk-around images. In Auscap's view, AI lets established businesses compress what might have been a 10-year product roadmap into one or two years and enhance margins in the process.

Yarra Capital Management has held this view throughout the sell-off. “We actually see CAR Group as more of an AI beneficiary rather than a business being disrupted,” Yarra said in June, pointing to the intellectual property within its platform and the potential for AI to drive more traffic to its sites. Hyperion Asset Management noted earlier in the year that CAR Group is embedding conversational language tools into core search and using AI internally to lift product output and efficiency, which it views as supportive of the business's long-term sustainability.

The international growth engine

Beyond the AI debate, managers point to a business that offers more growth than it did a decade ago. Pendal Group summarised the FY26 result trends in August: Australia growing around 7 per cent with some margin expansion, Brazil around 20 per cent with margin expansion, South Korea in the low teens with reinvestment required, and Trader Interactive in the US around 10 per cent. CAR Group is guiding to 9 to 12 per cent constant currency NPAT growth, according to Pendal.

Vertium described CAR Group as replicating its Australian playbook offshore, including expanding media revenue in the US, where it represents about 5 per cent of revenue compared with about 15 per cent in Australia, and importing its depth and premium tier model into Latin America. Vertium framed the return arithmetic simply: with underlying growth of about 13 per cent and a yield of about 4 per cent, the stock could deliver close to a 20 per cent return even without a re-rating.

The skeptics and the fence-sitters

Valuation views vary widely depending on who is measuring. Pendal described the stock as fully valued at 26 times earnings and 2.5 times PEG after the August result, sustainable only if AI fears remain muted, and flagged quality issues including costs taken below the line, a low tax rate, higher capitalisation and weak cash flow. Ralton Asset Management exited in September, citing valuation multiples of 27 to 29 times forward earnings under pressure from bond yields, tightening dealership margins pushing back against price increases, softening North American recreational volumes and A$1.2 billion of net debt.

Others are waiting for evidence. Wilson Asset Management rated the stock a hold in July, saying it wants to see signs of earnings re-accelerating before becoming more constructive, and Medallion Financial said the jury is still out on whether AI will be a positive or a negative. Firetrail Investments exited back in December 2025, arguing classifieds could remain out of favour until the impact of AI becomes clearer.

What managers are watching next

The next tests are tangible. Managers will watch whether the AI features Auscap described lift engagement and margins, whether Brazil and South Korea sustain their growth, and whether US recreational vehicle volumes hold up as Ralton fears they will not. Above all, they will watch whether earnings keep compounding while the multiple contracts. Auscap's view captures the bull case: CAR Group is well placed not only to defend its existing position but to use AI to accelerate product development and margin improvement.
