Amazon has held early exploratory talks to buy Flipkart even as the latter closes in on a sale to Walmart. Other than Amazon and Walmart, Google also offered to invest in the e-commerce firm at a valuation of $15-16 billion.

Apart from its eponymous platform, Flipkart owns fashion businesses Myntra and Jabong, eBay India and mobile payments firm PhonePe
