Despite legal troubles in its S.F. hometown and NYC, Airbnb is pushing ahead with a new round of funding that will raise the firm’s valuation to $30B. According to a disclosure filed with the State of Delaware, the home-sharing behemoth is raising $850M from unknown sources, Bloomberg reports. Last year Airbnb raised $1.6B. But with the funding disclosed in last week’s filing, Airbnb has raised about $3.2B in equity, according to Equidate.
