Right now Airbnb's IPO will be offered to institutions and others before it's offered to the general public. It would be great if Airbnb would give superhosts a chance to buy stock before it gets disbursed to the markets.
@O--C-0 Word has it they're going to do a direct listing, not an IPO, and if they do a direct listing, no new shares will be created. However, once it's listed on the Exchange, you'll be able to buy shares. It's not always great to get them in the IPO anyway, when prices are inflated as often as they're a good deal.
