Silicon Valley’s elite start-ups have been on a fund-raising tear, and Airbnb has become the latest to try to add to its cash pile.

Airbnb, which lets users list their homes and apartments for short-term rentals, is in talks to raise $1 billion in venture capital, according to a person close to the discussions. The financing round would value Airbnb at $24 billion, said the person, who spoke on condition of anonymity.

If the financing closes, Airbnb will more than double its valuation of $10 billion from just over a year ago. The company has garnered nearly $800 million in funding to date from investors including Sequoia Capital and Andreessen Horowitz.

A spokeswoman for Airbnb declined to comment.

Airbnb’s funding talks, which were earlier reported by The Wall Street Journal, are another example of the fast growth and interest in so-called on-demand start-ups, many of which are seeking hundreds of millions of dollars and ever-climbing valuations in their quests to upend existing industries.
