The bull case is that it has the potential to become as valuable as Marriott which is about $43 Billion in market cap.
Marriott for the most part has transitioned mostly to an all digital company over the past two decades. The Marriott of today is primarily about hotel operations (i.e. branding, bookings/pricing/revpar/SEO, front desk, housekeeping, wifi, remodeling) and its loyalty rewards program and mobile phone app (BonVoy).
Much of its assets have been moved to a standalone REIT that trades under a different ticker. In a way similar to WeWork, Marriott effectively leases hotels from the REIT.
So in that sense, if WeWork can be considered analogous to Marriott, then in a hand wavy way the $47 Billion market cap valuation could somewhat make sense.
The bear case is that its not a well implemented corporate structure full of accounting traps and is actually a fraction of Marriott's valuation...
