Flipkart Group, an Indian e-commerce marketplace, has announced an investment -- a mix of primary and secondary capital -- from SoftBank Vision Fund (SFTBF).

This is the biggest ever private investment in an Indian technology company, and will make the Vision Fund one of the largest shareholders in Flipkart. The investment is part of the previously announced financing round, where Flipkart had raised capital from three technology companies -- Tencent (TCEHY), eBay (EBAY) and Microsoft (MSFT). After this financing round, Flipkart will have in excess of $4B of cash on its balance sheet.
