Indian digital payments company Paytm is set to make its stock market debut on Thursday, after its $2.5 billion initial public offering (IPO), India’s largest, was oversubscribed last week. Paytm, which counts China’s Ant Group and SoftBank among its backers, raised $1.1 billion from institutional investors and last week received $2.64 billion worth of bids for the remaining shares on offer, or 1.89 times. The company, headquartered on the outskirts of India’s capital New Delhi, has priced its 85.1 million-share issue at the top of the range at 2,150 rupees ($28.92) each. It had flagged a price range of 2,080-2,150 rupees per share for the deal. Some market analysts said they expected the shares to nudge higher on their debut despite Paytm’s expensive valuation. Engineering graduate Vijay Shekhar Sharma founded Paytm in 2010 as a platform for mobile recharges. The company grew quickly after ride-hailing firm Uber listed it as a quick payment option in India and its use swelled further in late 2016 when New Delhi’s shock ban on high-value currency notes boosted digital payments. Paytm’s success has turned Sharma, a school teacher’s son, into a billionaire with a net worth of $2.4 billion according to Forbes. Its IPO has also minted hundreds of new millionaires in a country where per capita income is below $2,000. ($1 = 74.3550 Indian rupees)
