The company, which has raised $5 billion from investors including Microsoft, Google, and Twitter, says it is still struggling to make money after its IPO.
But investors are still willing to bet on Airbnb, according to data from Axios, which tracks securities and valuation trends.
Airbnb is trading for about $19.5 billion, and the company raised $3.5 million in March.
The company’s stock fell more than 30% in 2017.
The ride-sharing startup has been trying to shake up the Airbnb industry, opening up its platform to non-profits, including the National Endowment for the Arts, which is running a pilot program with Airbnb to use the platform to rent out concerts.
It’s been a big hit for the artists and music venues who have used Airbnb to host their events.
