There are some single-market/regional providers that I'm aware of currently offering spectrum, but I believe you'll be hard pressed to find others with national footprints in the US that will. Zayo and Lumen both did a bit of a will they/won't they with it for a long time, and my understanding is that neither of them currently offer it, or at least will tell you that publicly.
