UK digital challenger Zopa is in talks to raise $100 million in what could be its final funding round before going public, according to Sky News.

The raise, which would value the bank somewhat higher than its £750 million valuation from a £220 million round last October, is currently being discussed by the bank with both new and existing shareholders.

Having established itself as a leader in P2P lending, Zopa switched to becoming a typical bank two years ago. It achieved profitability this April and the £2 billion deposit milestone in August.

According to sources cited by Sky, the company, which has long been rumored to be contemplating an IPO, has gone to investors for what is anticipated to be the last capital infusion to fuel expansion.
