Airbnb Acquires HotelTonight to Expand Travel Portfolio

SAN FRANCISCO — Airbnb says it plans to acquire HotelTonight, a service for travelers seeking last-minute hotel bookings, in a deal that will expand the lodging-rental company’s portfolio with traditional and boutique hotel listings.

Terms of the deal were not disclosed. The acquisition values HotelTonight in the vicinity of its last private valuation, $465 million, said two people who were briefed on the deal and were not authorized to disclose the price. That would make it Airbnb’s biggest acquisition.
