Becoming the StandardNarrow moat

In a striking turn, Tesla's charging connector — once a proprietary design isolating its cars on their own network — has been¹ adopted by nearly the entire North American auto industry as the standard, with rival after rival agreeing to build the Tesla plug into their vehicles and give their customers access to the Supercharger network. Becoming the industry standard is a rare and powerful position: it puts Tesla's technology at the center of the continent's charging infrastructure and turns a former competitive wall into a toll road every EV maker must use.

The strategic value is considerable. As the standard, Tesla earns charging revenue from other brands' customers, gains influence over the direction of charging technology, and secures a durable, infrastructure-like position that persists regardless of how its car business fares. Standards, once established, are extraordinarily sticky — the whole industry has now built around Tesla's connector, and unwinding that would be enormously costly, giving Tesla a lasting, entrenched role few companies achieve.

The trade-off, as with opening the network, is that being the standard means sharing what was once exclusive. The advantage shifts from differentiating Tesla's cars to monetizing everyone's charging — a good business, but a different one, and one that helps rivals sell EVs by solving their charging problem for them. So becoming the standard is a genuine and unusual achievement that gives Tesla a durable infrastructure position and a new revenue stream, while quietly relinquishing the exclusivity that made the network a reason to buy Tesla in the first place.
