CarGurus, Inc. (CARG)

How it makes money

Most of the money comes from recurring monthly subscriptions paid by dealers for listing packages — Enhanced, Featured+ and Featured Priority+ — priced according to the dealer's inventory size and geography, on top of which dealers buy à la carte add-ons such as Highlight, Audience Targeting, New Car Exposure and Geo Expansion. A second stream is advertising sold to car manufacturers and brand advertisers, in formats such as brand reinforcement, category sponsorship and segment exclusivity. A third, smaller stream comes from partnerships with auto lenders, where CarGurus is paid on the number of loans actually funded after a consumer pre-qualifies on the site. The economics are therefore those of a subscription advertising business, not a transaction business: CarGurus does not take title to cars and, after the CarOffer wind-down, no longer earns anything per vehicle sold. Growth comes from adding paying dealers and from selling each existing dealer a richer package — what management calls expanding wallet share.

CarGurus is a two-sided marketplace: the more dealers list inventory, the more useful the site is to shoppers, and the more shoppers arrive, the more a dealer must be present. That loop is real and is reinforced by the Instant Market Value pricing data the company accumulates from years of listings, which is hard for a newcomer to replicate. But the advantage is bounded rather than wide. Dealers routinely subscribe to several marketplaces at once, so being present on CarGurus rarely means being absent elsewhere, and subscription contracts can be cancelled. The company itself discloses that it depends in part on internet search engines to bring consumers to its sites, which means a meaningful share of the demand side is rented rather than owned.

Demand is driven by how much dealers are willing to spend to move inventory, which in turn follows used-car volumes, vehicle affordability, interest rates and manufacturers' marketing budgets. The subscription model dampens the swings — a dealer paying monthly does not cut the line item the moment a quarter turns weak, and the platform kept growing revenue at a double-digit rate in both 2024 and 2025 — but it does not remove them: when dealer margins compress, packages get downgraded and add-ons get cut. The company itself says its operating results have been more influenced by macroeconomic conditions than by consistent seasonal patterns, while noting the usual spring and summer lift tied to tax refund season and higher discretionary spending, and that it may become more susceptible to seasonality as it scales.

Key risks

• Dependence on dealer relationships and subscription renewals — The company states that its business is substantially dependent on its relationships with dealers and that it must maintain or increase the number of dealers paying subscription fees. Dealer agreements can be terminated, and dealer consolidation reduces the number of separate paying customers.
• Reliance on internet search engines for traffic — CarGurus discloses that it relies in part on internet search engines to drive traffic to its websites. Changes in ranking algorithms or in how search results are presented are outside the company's control and can affect the flow of consumers to the marketplace.
• Exposure to the wider automotive ecosystem and macroeconomic conditions — The filing lists risks tied to the larger automotive industry ecosystem and states that future revenue is uncertain, including because of potential macroeconomic effects. Inflation, interest rates and vehicle supply all feed through to dealer advertising budgets.
• Disputes over the accuracy of pricing and valuation products — The company flags that it may be subject to disputes regarding the accuracy of its pricing and valuation products. Deal ratings and Instant Market Value are central to the consumer proposition, so challenges to them go to the heart of the product.
• Data privacy, cybersecurity and service disruption — The filing discloses risks from the collection, processing, storage and sharing of personal data by the company and its third-party service providers, and separately warns that a significant disruption in service on its websites or mobile applications could harm the business.
• Competitive market — Among its general risk factors the company states that it participates in a competitive market and faces pressure from existing and new companies. Rival marketplaces, dealer software vendors and manufacturers' own channels all compete for the same dealer spend.
• Founder control of voting power — The company discloses that its founder controls a majority of the voting power of its outstanding capital stock, through a dual-class structure. Holders of Class A common stock therefore have limited influence over matters submitted to a shareholder vote.
• Failure to develop new products or adapt to new technologies — The filing warns that any inability to develop new products or adapt to new technologies could harm the business. This is stated as a company risk factor and is relevant to a marketplace whose discovery layer is being reshaped by AI-based search and assistants.

The filing does not disclose a figure for the share of revenue taken by the largest customers, and identifies no single customer as a material concentration. The structural picture is one of dispersion: revenue comes from 34,409 paying dealers at the end of 2025 — 26,049 in the United States and 8,360 internationally — each on its own subscription, so no individual dealer is large in relation to the group. The offsetting exposure is not to one customer but to the category: the company states that its business is substantially dependent on dealer relationships as a whole, and the advertising stream concentrates on a small number of car manufacturers.
