Enter a ticker to learn what the company does and how it makes money.
Tesla builds and sells electric cars, along with batteries and solar products, and increasingly makes money from software and energy storage.
Tesla is the company that made electric cars feel normal—and fast. It sells electric vehicles to regular people and fleet buyers, from the Model 3 and Model Y family cars to the bigger Model S and Model X, plus the angular Cybertruck pickup. For most of its life, the cars were the whole story: Tesla designs them, builds them in its own factories, and sells them directly to buyers, skipping the dealerships that traditional automakers rely on.
That direct-sales model matters more than it sounds. Traditional carmakers sell through franchised dealers, who hold inventory and take a cut. Tesla sells online and through its own stores, which gives it tighter control over pricing and inventory—but also means it eats the cost when demand softens. That cost has shown up lately: Tesla cut prices sharply starting in 2023 to defend its sales, and its once-enviable profit margins on cars shrank. The car business is also brutally competitive now, with cheap Chinese EVs from BYD pressing hard and every major automaker selling electric models of its own. The quieter second act is energy. Tesla sells battery packs for homes and utilities—its Megapack grid batteries have become a real, fast-growing business—and solar panels and roof tiles. Energy storage is simpler money than cars: utilities pay for big battery installations, and Tesla holds a leading position. Then there is the speculative third layer: Tesla has bet heavily on self-driving software, robotaxis, and humanoid robots, and its sky-high stock price is really a bet on those future businesses more than on car sales. It also runs a network of Supercharger fast-charging stations, which other automakers have begun paying to use.
Tesla spends its cash the way a company that believes it is building the future does: on new factories, battery development, and artificial intelligence computing chips for autonomous driving. Those big bets are the core of the controversy around the company. Supporters see a rare company that turns big engineering dreams into real products. Skeptics see a car company priced like a tech giant, run by a founder whose public persona and political activity create risk, and facing a car business that is no longer growing the way it used to.
