Airbnb has already overtaken major hotel companies in terms of its valuation by investors, but its growth could have it outpacing them in more concrete terms—actual guest bookings—in a few years, according to a Barclays research report.
The rooms available in 2014 jumped from 300,000 in February to a million in December, while the largest hotel company in Europe measured by rooms, InterContinental Hotels Group (IHG), had about 698,000 rooms in its portfolio. Airbnb offers more rooms than many of the largest hotel groups in the world–Hilton, InterContinental and Marriott—which each maintain just under 700,000 rooms. (Marriott said today at the World Economic Forum that it expects its portfolio of hotels to surpass 1 million rooms by the end of 2015.)
