Airbnb, who will go public in December 2020, filed an initial public offering (IPO) prospectus with the U.S. Securities and Exchange Commission (SEC) saying that "future success will be dependent on adapting to new technologies such as tokenization, cryptocurrencies, and new authentication technologies." Wall Street Journal reports that Airbnb's IPO could value the company at $30 billion. In 2014, Airbnb CEO Brian Chesky asked his followers on Twitter if Airbnb should accept bitcoin, sparking a public interest in AirBnb adopting cryptocurrencies. They also mentioned "distributed ledger and blockchain technologies" as areas where they anticipate short-term losses due to aggressive research and development. Another critical component to the future of Airbnb will be their ability to integrate new or emerging payment methods into their platform, they said in the prospectus. "Alternate payment providers such as Alipay, Paytm, and WeChat Pay operate closed-loop payments systems with direct connections to consumers and merchants in mobile-centric countries [like Asia, Africa, and Latin America]." According to Airbnb data, there are 2.9 million hosts on Airbnb worldwide in 2020 with an average of 7 million listings for sale on Airbnb at any given time across 100,000 cities and 220 countries. Over 14,000 new hosts are joining each month. Competitor is vacation rentals marketplace Vrbo with 2 million rentals for sale. Vrbo was acquired by HomeAway in 2006, then Expedia Group acquired HomeAway for $3.9 billion in 2015.
