According to a report in the WSJ, Pinterest has filed for an IPO with the S.E.C. and the valuation is expected to be at least $12 billion.

Pinterest and its underwriters, led by Goldman Sachs Group Inc. and JPMorgan Chase & Co., are eyeing a late-June listing, according to people close to the deal. They warned that, as always with IPOs and unpredictable markets, the timing or valuation could shift. Pinterest most recently raised funding privately at a valuation of $12 billion.
