Airbnb is raising another $850 million, valuing the company at $30 billion, Bloomberg reported. The news stems from a late July filing in Delaware. One year ago, the sharing economy powerhouse was worth $25.6 billion, according to Equidate. Not including its most recent influx of cash, Airbnb has raised $2.39 billion since its 2008 launch. The additional $850 million brings that to just over $3.2 billion. The funding round is also part of a continued effort to avoid going public, the Wall Street Journalnoted. And comes at a time when Airbnb, which lets members rent out and book each other's rooms or homes while traveling, is still battling with cities like San Francisco over its ever-growing presence and subsequent effects on the housing and hotel markets. More and more cities and states are now trying to tax Airbnb, too. TopicsAirbnb
