One company is the largest fast-charging network in 48 of the 51 states and DC: Tesla, which holds 50% of every public DC plug in the country. Its grip is not even, though — 74% of Nevada’s plugs against 24% of Vermont’s — and in 3 places somebody else leads.
Why the owner of the plugs matters to you
A charging map looks the same whoever built it, and a plug count says nothing about whether you can use the plug. Networks differ on the thing that decides a road trip: how many stalls sit at each site, whether the site is lit and staffed, what a kilowatt-hour costs, and whether your car can open the flap at all. When one network holds 74% of a state’s plugs, as it does in Nevada, that state’s charging experience is that network’s charging experience, and a bad week for the operator is a bad week for every driver in it.
The counts below are of plugs, not of plugs you personally can use. Our extract records the network and the plug count for each site; it does not record whether a given Tesla Supercharger stall accepts a non-Tesla car, which varies site by site. Read the Tesla column as concentration of ownership, not as a promise or a lockout.
Every state, by how concentrated its plugs are
Sorted by the share the largest network holds. The 3 rows where the leader is not Tesla are highlighted. The last column is registered electric cars, so you can see the states where a lot of drivers depend on a single operator — the full ratio is in how many EVs share each charging plug.

The three places Tesla does not lead
Michigan is led by Red E with 571 of its 1,746 plugs (33%), Oklahoma is led by FCN with 426 of its 897 plugs (47%), Hawaii is led by OpConnect with 72 of its 179 plugs (40%). Puerto Rico, which is in the federal extract but outside the electricity table we use for cost, has 1 public DC plugs in total, all ChargeLab. These are the states where a second network got to scale first, usually with public money behind it, and they are worth watching: they are the closest thing the US has to a control group for what a less concentrated market looks like.
Concentration is not the same as coverage
A state can be dominated by one network and still be well served, or split between several and still be thin. Nevada has the most concentrated market here at 74%, and 1,174 plugs for 85,600 registered electric cars. Vermont is the least concentrated at 24% and has 319. The number that actually predicts a queue is cars per plug, not brands per state.
The other half of the picture is how many plugs sit at each site. Nationally 4,978 of the 15,433 public fast-charging sites have exactly one plug, so if it is busy or broken there is no second stall — counted out in how many fast chargers the US really has.
Frequently asked questions
Which company owns the most EV chargers in the US?
Tesla, by a wide margin: 38,307 public DC fast-charging plugs at 3,110 sites, 50% of every public fast plug in the country, and the largest network in 48 of the 51 states and DC.
Which states are not led by Tesla?
Michigan (Red E), Oklahoma (FCN), Hawaii (OpConnect). In every other state and in DC, Tesla holds more fast-charging plugs than any other single network.
Does a Tesla plug work on my car?
Sometimes, and this data cannot tell you which times. The extract records the operator and the plug count for each site, not whether that site accepts other cars, which Tesla has been opening selectively. Treat the share column as a measure of who owns the infrastructure in a state.
Is a concentrated charging market a bad thing?
It is a risk rather than a verdict. One operator means one pricing policy, one app and one maintenance schedule for most of the state, so an outage or a price rise reaches nearly everybody at once. Against that, the largest network here also puts the most plugs per site, which is the single thing that stops a queue forming.
