CarGurus is pulling away from competitors by shedding unprofitable operations while monetizing AI-powered dealer tools that demonstrably improve customer results.

While the broader market has been grinding lower in early 2026, CarGurus (NASDAQ:CARG) has been quietly doing something most auto marketplace competitors can only dream about: growing faster, getting leaner, and embedding itself deeper into dealer operations across the country and internationally. The stock is up 12.4% since its Q4 earnings report while SPY has dropped 2.11% over the same stretch. That divergence deserves a closer look.

For years, CarGurus carried the weight of CarOffer, its wholesale vehicle transactions business, which struggled in a volatile used-car pricing environment. That drag is officially over. The wind-down of CarOffer completed December 31, 2025, and the financial results speak for themselves.

Full-year 2025 gross profit hit $841.5 million, up nearly 14% year-over-year, while operating income exploded. Free cash flow came in at $265.96 million, up 47.49% for the year. This is what the core marketplace business looks like without subsidizing a money-losing wholesale operation.

CarGurus launched more new products in 2025 than any prior year, and early adoption data is compelling.

CEO Jason Trevisan said on the Q4 earnings call:

"On average, last year, we ingested approximately 0.5 billion first-party shopper signals each day, translating them into real-time consumer demand, pricing and inventory insights our dealer customers are leveraging for measurably improved performance."

PriceVantage, the company's AI-powered inventory pricing tool, launched in October and is already showing results. Nearly 80% of adopting dealers are active weekly on the PriceVantage suite, and early adopters reported five times faster vehicle turn times and a 71% increase in daily shopper connections. That's ROI dealers can see on their lot.

CG Discover, the company's conversational AI search tool, saw traffic grow 3.5x and leads grow 10x quarter-over-quarter. Discover users spend 4.4x more time on the platform than regular visitors.

Total paying dealers reached 34,409 in Q4, up 7% year-over-year. The more telling number is QARSD, or quarterly average revenue per subscribing dealer, which hit $6,616, up 8%. CarGurus isn't just adding dealers -- it's extracting more value from existing ones as they adopt more tools.

Management expects the monetized dealer products launched in 2025 to grow approximately 15x in 2026 and reach eight-figure revenue levels, a meaningful new revenue stream not yet in most analysts' models.

Compare that to Cars.com (NYSE:CARS), which carries a market cap of just $466.5 million with a profit margin of only 2.77%. CarGurus is operating in a different league with a 17.2% profit margin and a 43% return on equity.

The 2026 guidance calls for 10% to 13% revenue growth with deliberate margin compression as the company invests in AI. Management has framed this as an intentional investment in long-term product differentiation, with early adoption metrics from PriceVantage and CG Discover cited as indicators of progress.

Wall Street is pouring billions into AI, but most investors are buying the wrong stocks. The analyst who first identified NVIDIA as a buy back in 2010 — before its 28,000% run — has just pinpointed 10 new AI companies he believes could deliver outsized returns from here. One dominates a $100 billion equipment market. Another is solving the single biggest bottleneck holding back AI data centers. A third is a pure-play on an optical networking market set to quadruple.
