300 kW chargers are pretty common here (Denmark), I did a search, and the fastest I can find is 400kW. But they are rare, and I don't think many cars can utilize that yet.
I have no doubt that when cars that can handle 1MW become common, we will also get the chargers for them. But it will probably also be expensive to use.
China doesn't have 1MW yet either, BYD has just begun building them. The fastest Tesla supercharger here is 250 kW.
