Rivian has its own network of chargers with the level 2 AC chargers, called waypoints, having already been opened up to all. Now they're projecting their
DC fast charging network to be open to all by the second half of 2024. It's at about 70 stations so far and each station usually has 6 stalls. There are more planned to be opened, but it's kind of decent little network for what is a very small player in the automotive world.
