DC-based daily deals site LivingSocial plans to raise around $1 billion in an initial public offering (IPO) likely to be filed in the coming weeks. The company has picked JPMorgan Chase, Bank of America and Deutsche Bank as lead underwriters, CNBC first reported. News of the IPO, which would value the company at $10-$15 billion, comes more than a month after chief rival Groupon filed to raise up to $750 million in its IPO. LivingSocial in April raised $400 million in a round of funding that included Amazon and LightSpeed Venture Partners, and reportedly valued the company at more than $3 billion, according to Potomac Tech Wire.
