NSE IPO Grey Market: Back Blockbuster Issue as GMP Points to Strong Listing Gains

Post

The financial markets are buzzing with anticipation as the National Stock Exchange (NSE) prepares to launch its monumental ₹22,561.57 crore initial public offering on September 17, 2026. After experiencing a minor dip in its grey market premium (GMP) earlier in the week due to valuation discussions and broader global market pressures, the NSE GMP has made a solid rebound. According to leading grey market tracking platforms such as InvestorGain and IPOWatch, the current GMP is hovering between ₹210 and ₹218. Based on the upper price band of ₹1,785 per share, market observers are estimating a potential listing debut around the ₹2,000 mark, indicating projected listing gains exceeding 10 percent for successful allottees.

Industry Experts Bullish on NSE’s Growth Potential and Financialization Surge

Market sentiment received a major boost following comprehensive analyses shared by top financial experts on CNBC-TV18's Market Forum, including veteran investors and fund managers like Ramesh Damani, Harsh Raghavan, Manish Kejriwal, and Harish Krishnan. Panelists lauded the NSE as a premier proxy for India’s ongoing financialization wave and digital trading boom. Ramesh Damani expressed strong confidence that the IPO will witness overwhelming investor demand and maintain its status as a high-growth compounding stock. Echoing this sentiment, Manish Kejriwal praised the exchange's exemplary management track record, while Harsh Raghavan projected potential listing gains of up to 20 to 22 percent, noting that the stock remains under-allocated in many existing mutual fund portfolios, leaving substantial room for institutional accumulation. Meanwhile, Harish Krishnan pointed out that while valuations are premium, the structural earnings growth and dominance of the exchange position it well to deliver positive surprises over the long term.

Essential IPO Details, Price Band, and Listing Schedule
