In CA, I think United Healthcare has the smallest share of customers out of all the exchange insurance companies…
If they left, maybe they lose 1% of customers? It could also be a cost cutting move since they aren’t really playing in the state anyways…
That said, I think Blue Shield made the most in 2014 from a latimes article I read…so some companies were able to make money, of course, Blue Shield and Blue Cross/Anthem are bad IMO.
