SoftBank is holding talks to increase its investment in Paytm Mall, reported The Economic Times.

As per the report, the Japanese firm, which may sell its stake in Flipkart could boost its investment in Paytm Mall as it will be freed from a clause in its agreement with Flipkart that prevents it from investing more than $500 million in Paytm Mall until 2020.

The firm currently holds 21% stake in Paytm Mall and as per sources mentioned in the paper, is holding talks to invest as much as $3 billion in the company.

While the decision about selling stake in Flipkart has not yet been finalised, the report said that the firm could pocket about $4 billion if it sells its entire 21% stake.

If the proposed investment by the Japanese firm becomes a reality, the Indian e-commerce industry could well witness a three way competition between Walmart controlled Flipkart, e-commerce giant Amazon and Paytm Mall.
