NSE IPO GMP Today: Premium Falls to ₹48 on Final Day—What It Means for Investors

The much-awaited National Stock Exchange (NSE) IPO enters its final day of bidding on Monday, September 21, with the grey market premium (GMP) falling sharply from the levels seen when the price band was announced.

The latest reports put the NSE IPO GMP at around ₹48, down from approximately ₹192 when the price band was initially announced. At the upper price band of ₹1,785, the latest GMP indicates an unofficial premium of roughly 2.7%.

The decline has shifted some of the market discussion from the possibility of large listing gains to questions around the potential listing premium and downside risk. However, GMP remains an unofficial indicator and does not guarantee how NSE shares will perform after listing.

NSE IPO GMP Falls Sharply

The NSE IPO initially generated considerable interest in the grey market. However, the premium has steadily declined during the subscription period.

Reports had earlier put the GMP at around ₹192, while it subsequently dropped to ₹58 and has now been reported at around ₹48 on the final day of bidding. Based on the upper issue price of ₹1,785, a ₹48 GMP translates into an indicative premium of about 2.7%.

The fall in GMP does not necessarily mean that the IPO will list at a similar premium or discount. Grey-market transactions operate outside the formal stock-market mechanism, and GMP can change before listing.

NSE IPO Subscription Crosses 1.4 Times

Despite the decline in GMP, demand for the NSE IPO has remained significant.

The ₹22,561.57-crore issue was fully subscribed by the second day of bidding. On the third and final day, total subscription had reached around 1.46 times the shares on offer, according to the latest reported figures.

Institutional and non-institutional investors have accounted for much of the demand, while retail participation has been comparatively slower. The latest reports put retail subscription at around 87% of the shares reserved for that category.

This contrast—strong overall subscription but a sharply lower GMP—has become one of the key talking points around the NSE IPO.

NSE IPO Price Band, Issue Size and OFS Details

The NSE IPO has a price band of ₹1,700 to ₹1,785 per share. The issue comprises an Offer for Sale (OFS) of approximately 12.64 crore equity shares by existing shareholders.

Since the issue is entirely an OFS, NSE itself will not receive fresh capital from the IPO. Instead, the proceeds will go to the shareholders selling their shares.

At the upper end of the price band, the issue is valued at approximately ₹22,562 crore, making it one of India's largest IPOs.

Why Has the NSE IPO GMP Fallen?

Several factors are being discussed in the market in connection with the decline in GMP.

One is the sheer size of the offering. With more than ₹22,500 crore worth of shares being offered, the large supply can affect the potential for a sharp listing premium.

The all-OFS structure is another factor. Because there is no fresh issue, NSE does not receive new capital from the offering.

There are also broader concerns surrounding NSE's dependence on trading activity, particularly derivatives volumes, as well as regulatory changes affecting the segment. Reuters reported before the IPO that investor caution was partly linked to changes in derivatives trading and declining volumes from previous peaks.

These factors have contributed to debate over the valuation and the potential for short-term listing gains.

When Will NSE Shares Be Listed?

The NSE IPO opened for subscription on September 17 and closes on September 21, 2026.

According to the IPO schedule, the basis of allotment is expected on September 22, refunds and share credits are scheduled for September 23, and the shares are expected to be listed on September 24.

What Does the Falling GMP Mean for NSE IPO Investors?

The fall in GMP suggests that grey-market expectations for the listing premium have moderated compared with the initial levels. However, it should not be treated as a definitive indication of the listing price.

The NSE IPO also needs to be assessed on factors beyond the grey market, including valuation, financial performance, regulatory developments, business growth, trading volumes and the risks outlined in the company's offer documents.

With bidding closing on September 21, investors now face the final opportunity to participate in the issue before the allotment process begins.
