Paytm's offer of up to 183 billion rupees, which was increased last month from 166 billion rupees, garnered interest from 122 institutional investors who bought more than 38.3 million shares for 2,150 rupees apiece, according to a regulatory document dated Nov. 3. Several companies including Paytm have tapped capital markets this year in a fund-raising frenzy on the back of record highs hit by the Indian stock market, which has outperformed Asian peers so far this year.
