NSE IPO Opens as Grey Market Premium Signals Weaker Gains
The National Stock Exchange of India is offering shares to the public.
The shares cost between ₹1,700 and ₹1,785 each.
The IPO received some investor interest on its first day.
In unofficial trading, called the grey market, the extra amount people may pay for the shares has fallen.
A ₹125 premium would suggest a possible listing price of about ₹1,910.
However, grey-market prices are not official and may not accurately predict the real listing price.
The IPO shares are being sold by existing shareholders, not by NSE itself.
NSE also reported that its revenue and transaction-charge revenue fell in FY26 compared with FY25.
The NSE IPO opened with a price band of ₹1,700–₹1,785 per share and will remain open until September 21, 2025.
The issue attracted 0.30-times subscription by 1:20 p.m. on its first day, with reported issue values of ₹22,569 crore and approximately ₹22,561.57 crore.
The grey market premium was reported at ₹125 before recovering to about ₹148 by 3 p.m., remaining below recent levels.
At the upper price band, a ₹125 GMP implies a potential listing price of about ₹1,910 and an estimated gain of roughly 7%.
The IPO is an offer for sale by existing shareholders, while NSE reported declines in FY26 operating revenue and transaction-charge revenue.
