It's not, but WeWork heavily implied they are and that seems to be a key part of their new strategy. Obviously many people are skeptical (including myself), but I suppose we'll find out soon enough.
Apparently the unit economics are still showing lost money because they aren't fully leased at many of their locations so their rationale is that as those locations, mature, they will fill up. Which is pretty normal in the real estate market.
But it's definitely not a certainty that the locations will fill to capacity.
