Why? It certainly has the feel of a 'public' stock that'll keep making news regardless. Not sure why they were losing money last year though, seems like you could run that thing with minimal operating costs. If they've improved their lean-ness via pandemic cutbacks I could see them benefitting from a travel business bounce and being in the news for it a lot. But no idea if they can/will actually be profitable (and if it matters?!).
Out of all the newish, gig/sharing, disruptive companies out there, I still haven't used Airbnb, and I don't like to invest in companies that I do not patronize. I looked into it a few times for trips, and it didn't seem to save me much money, and seemed less convenient than a traditional hotel booking or beach rental. Additionally, I do not know too many people who use Airbnb. I have used the likes of Uber, Uber Eats, Door Dash, Dine In CT, Poshmark, Robin Hood, PayPal, Venmo, and I'm sure a few others I can't recall at the moment, but even those wouldn't be ideas I would invest in (expect PayPal, which I am on HEAVY). I also think the IPO will considerably over value them.
