NSE IPO Listing Tomorrow: GMP Falls to 2.5% Ahead of Market Debut

Reported by News Desk (Editorial Desk)

September has been a largely positive month for IPO listings, with most newly listed stocks trading above their issue prices. The spotlight now shifts to the ₹22,562-crore NSE IPO, which was subscribed 5.71 times but has seen its grey market premium fall to around 2–2.5% ahead of its BSE debut.

NSE IPO Set for September 24 Listing as GMP Cools

The much-awaited National Stock Exchange of India (NSE) IPO is scheduled to make its stock-market debut on September 24, 2026, with shares set to list on the BSE.

The ₹22,562-crore public issue attracted strong overall demand during its three-day subscription period, closing with 5.71 times subscription. Qualified institutional buyers (QIBs) subscribed 12.68 times their allotted portion, while the non-institutional investor category was subscribed 6.55 times. Retail investors subscribed 1.39 times.

The IPO was entirely an offer for sale (OFS) involving around 12.64 crore shares. This means the proceeds will go to existing shareholders selling their stakes rather than directly to NSE.

September IPOs Have Mostly Rewarded Investors

NSE's debut comes against a relatively strong backdrop for IPO listings in September. According to Ace Equity data cited by Economic Times, 16 IPOs had listed during the month, with the majority opening above their issue prices. Five had listed below their issue prices and one opened flat.

Some stocks have delivered particularly strong listing gains. ESDS Software Solution, for example, listed at ₹746 against an issue price of ₹429, representing a 74% listing gain. However, the post-listing performance of individual IPOs has varied, showing that an initial premium has not necessarily translated into sustained gains.

NSE GMP Falls Ahead of Debut

The key talking point ahead of NSE's listing is its declining grey market premium (GMP).

Moneycontrol reported a GMP of around ₹45.5, implying an indicative price of approximately ₹1,830.50 against the upper issue price of ₹1,785 — a premium of about 2.55%. Economic Times reported the premium at around 2.4%.

GMP is an unofficial market indicator and can change before listing. It does not guarantee the actual opening price on the exchange.

With NSE's large issue size and the availability of a substantial number of shares for trading, market participants will be watching whether strong institutional subscription translates into a sizeable listing premium.

NSE IPO: What Investors Are Watching

The NSE listing will be closely tracked not only because of the size of the IPO but also because it marks the public-market debut of one of India's major market infrastructure institutions.

For investors, the September IPO trend, strong institutional participation and declining GMP offer different signals. The actual market price on September 24 will ultimately depend on demand and trading conditions when the shares begin trading.
