Public DC fast EV charging rapidly expands in the US in Q1

The expansion of public DC fast charging infrastructure in the United States has accelerated significantly in the first quarter of 2026, with over 3,500 new charging ports added. This growth outpaces the previous year’s first quarter, which saw just over 2,700 new stalls. The total number of public DC fast charging ports has now surpassed 71,000 across more than 15,000 sites, reflecting a robust investment in EV infrastructure despite ongoing scepticism from some US automakers about consumer demand for electric vehicles. Key data from the Alternative Fuels Data Center (AFDC) reveals that the average size of charging sites is increasing, with more ports available per location than a year ago. However, the reported number of sites can be somewhat misleading due to the way adjacent stations operated by different networks are counted separately. The industry is dominated by a handful of major networks, which control roughly 85% of the total DC fast charging ports. Tesla remains the largest network by a wide margin, operating over 36,800 ports, although its market share has declined slightly to 51.6% as other networks expand. Tesla’s Supercharger network continues to grow, adding nearly 1,200 new ports in the first quarter alone, and more than two-thirds of its stations are now accessible to non-Tesla vehicles. This move towards greater interoperability is significant in broadening access to fast charging for all EV owners. Other leading networks include Electrify America and EVgo, each with over 5,000 ports, and ChargePoint, which ranks fourth but does not own most of its chargers outright, highlighting the complex ownership structures within the sector. The rapid expansion of DC fast charging infrastructure signals a strong response to the increasing demand for electric vehicles and addresses one of the key barriers to EV adoption cited by critics: the availability of reliable, fast charging. As the market continues to mature, the diversification of networks and the growth of site capacity will be crucial in supporting the transition to electric mobility across the US. With Tesla’s market share expected to dip below 50% soon, competition among charging providers is likely to intensify, potentially driving further improvements in coverage and service quality.
