San Francisco (Reuters): Airbnb Inc, peer-to-peer online marketplace and homestay network, is planning to raise an additional $153 million as an extension of a recent grant round, boosting its treasures as the company moves forward with global expansion.

According to venture capital database, Airbnb authorised the sale of up to $153 million in equity to investors which obtained the company's financial filing. The funding is an extension of a round in September, when Airbnb raised more than $555 million , according to financial filings. Investors have valued the company at $30 billion.

The price-per-share for the sale is $105, up from the $93.09 share price the company commanded in its 2015 financing round.

Airbnb , which provides a platform for homeowners to rent out their house or a room, has enjoyed tremendous growth but has also faced an intensifying global battle with regulators who say the service takes the affordable housing off the market and drives up rental prices. Several dealmakers have said they expect the company to go public next year.
