America's electric vehicle fast-charging market keeps throwing surprises every quarter. Despite the reset in EV sales momentum, the fast-charging network continues to grow at a rapid clip. New players like Ionna have ramped up quickly, deploying hundreds of new ports in just about a year since entering the market. But retail giant Walmart is coming in hot with its own charging ambitions, posting some serious numbers for Q2.

According to EV charging data platform Paren, Walmart outranked every charging network except Tesla in second-quarter deployments. Walmart added 368 new ports in Q2, behind Tesla's 1,185 but ahead of ChargePoint (333), Red E (315) and Electrify America (202). That means Walmart alone accounted for 8.4% of new public fast-charging stations in the U.S. during the quarter, even though its all-time market share is still below 1%.

It's a remarkable surge for the retail giant. In the first quarter, Walmart ranked ninth in deployments, and it didn't even crack the top ten in the fourth quarter of last year. Within a few months, it's become the second fastest-growing EV charging network in the country.

Walmart might hold the secret to supercharging EV adoption in America, and it's just getting started. Its footprint of more than 3,500 Supercenters gives it a structural advantage that practically no other charging network can match. It already owns the real estate, so it doesn't have to negotiate leases or seek landowners' permission. Every Walmart store sits on a huge parking lot, which means there's plenty of room and flexibility to build large charging sites with multiple stalls. They also have bathrooms and food options, too, helping them compete with modern amenity-providing stations.
