Vijay Shekhar Sharma-led Paytm's e-commerce vertical is reportedly raising $180-200 million (around ₹1,210 to ₹1,350 crore) in a funding round led by Chinese e-commerce giant Alibaba. The incoming investment would value the online retailer at about $1 billion. Paytm's parent company One97 was valued at nearly $5 billion the last time it raised about $60 million funding in August 2016.
