Tesla has committed to making much of their supercharger network accessible to other EVs: https://www.tesla.com/support/supercharging-other-evs. As part of this effort, they are installing "Magic Docks" at some superchargers, which allow other EVs to use the superchargers with no need to bring an adapter.
This market resolves YES if the map at https://www.tesla.com/findus shows at least one "Supercharger Open to Other EVs" in each US state at or before midnight Pacific time on March 31, 2025. In particular, this could resolve early!
Note that Washington DC is not a US state.
May be resolved by another reputable source if need be (e.g. if Tesla takes down their interactive map). I will use my best judgement.
@diracdeltafunk Huh I'm sorry this seems to be wrong, I don't see NH on the map now. Also I must have missed OH and HI. I'll try to update with a more accurate count soon.
It looks like right now we're missing: ID, MT, WY, ND, SD, WI, NH, NV, KS, WV, VA, NM, OK, AR, TN, NC. I might have missed something, I just did a quick scan by eye!
