DC fast-charging infrastructure in the United States is gradually expanding, even after the halt of the $5 billion NEVI program. It’s not a surprise, as the EV market continues to grow and requires more and more charging stations.

According to data provided by the Alternative Fuels Data Center, as of May 1, 2025, there were 55,750 DC fast-charging ports installed, including points that were temporarily unavailable (roughly 1.9%). That’s a few thousand more than in February (which had 52,250+).

The number of locations was estimated at roughly 12,800, which on paper is only slightly more than three months ago. However, this raw number might be a bit misleading because the real number of stations increased by a few hundred. The reason for that is simple — for the first time, the database shows a correct number of Rivian Adventure Network sites (111 instead of 600+ previously, which was the number of ports).

The numbers might differ slightly depending on the exact date of access, so please treat them as a close estimate.

Top DC Charging Networks by Ports

The top five largest DC fast-charging networks by the number of charging ports remain the same, but their combined market share decreased from 84% in February to 82%.

The Tesla Supercharging network recently exceeded 30,000 stalls, reaching 30,767 as of May 1, 2025. However, its share decreased by more than one percentage point to 55.2%.

The next three networks — Electrify America, EVgo, and ChargePoint — are relatively similar in size, with between 4,000 and 4,800 charging ports. Interestingly, ChargePoint is now ahead of EVgo.

The top DC fast-charging networks are as follows:

1. Tesla Superchargers: 30,767 ports (a 55.2% share)
2. Electrify America: 4,799 ports (an 8.6% share)
3. ChargePoint: 4,249 ports (a 7.6% share)
4. EVgo: 4,083 ports (a 7.3% share)
5. EV Connect: 1,668 ports (a 3.0% share)
   Top 5 networks: 45,566 ports or an 81.7% share
   other: 10,188 ports (an 18.3% share)
   

For the very first time, the Ionna charging network emerged in the stats with 13 locations and 122 stalls. We know that they are quickly expanding.

It will be very interesting to see the progress of the expansion of the Walmart EV charging network, as it might become another new heavyweight player like Ionna. Walmart plans to install thousands of charging stations with potentially a five-digit number of charging stalls.

As a side note, we must add that the Tesla Supercharging network has only NACS (SAE J3400) plugs, while the other networks use mostly CCS1, with the addition of some CHAdeMO and a very small number of NACS (SAE J3400).
