The National Stock Exchange of India (NSE) officially debuted on the BSE on Thursday, September 24th, after a nearly decade-long wait for its public listing. The shares opened at ₹1,800, a ₹15 premium over the issue price of ₹1,785, resulting in a modest listing gain of approximately 0.84% for allottees. Despite the flat debut, the listing instantly positioned NSE among India's most valuable listed companies, with a market capitalization of roughly ₹4.46 lakh crore.

The initial public offering (IPO) was a substantial $2.3 billion issue, India's second-largest on record, and was oversubscribed 5.71 times, attracting bids worth close to ₹90,000 crore against an issue size of around ₹22,560 crore. Institutional investors, specifically qualified institutional buyers (QIBs), drove much of this demand, with their portion receiving over 12 times the subscription. Anchor investors, including foreign sovereign wealth funds and domestic institutions like LIC, had already contributed ₹6,746 crore before the public offering.

Market observers had predicted a modest debut, with grey market premiums (GMP) signaling gains between 2% and 5%. Experts like Arun Kejriwal of Kejriwal Research and Investment Services and Mahesh M. Ojha of Kantilal Chhaganlal Securities advised long-term investors to hold the shares due to NSE's strong fundamentals, reflecting India's GDP growth. However, short-term and listing-gain investors were advised to maintain a strict stop-loss at ₹1,740 per share due to the stock's sensitivity to market trading volumes and potential regulatory shifts from SEBI. The debut also comes amid concerns about a cooling derivatives market in India.
