Nope, in a statement they made they said: "No Man's Sky will be a completely vast single player game with tons of explore ability, you will be able to discover planets and name them for your friends to see. Although multilayer content will not be present, we are considering adding something in the long future".
At least with star citizen you can do the same, in an actual MMO where multi crew ship combat etc. is available. I see this being like Subnautica etc. Looks good but just doesn't have anything to bring you back.
