Why has Zomato further increased the size of its IPO?

Zomato has not only increased the size of its IPO but also advanced the date. Instead of opening on 19 July as originally planned, the Zomato IPO could now open as early as 14 July itself. Only the ROC approval of the red herring prospectus is pending. The fresh issue portion has been hiked further from Rs.7,500 crore to Rs.9,000 crore with an additional Rs.375 crore coming from OFS for Info Edge.
