NSE IPO GMP Today: Grey Market Premium Stands at 3% on Final Day
The National Stock Exchange of India (NSE) IPO has entered its third and final day of bidding on September 21, 2026. The ₹22,569-crore public issue has maintained steady demand, while its grey market premium (GMP) is currently around ₹48 per share, or approximately 3% above the upper price band of ₹1,785.
Based on the prevailing GMP, the indicative listing price works out to around ₹1,833 per share. However, GMP is an unofficial market indicator and does not guarantee the actual listing price.
The NSE IPO received bids for 1.16 times the 8.86 crore shares on offer by the end of Day 2. The retail category was subscribed to 72%, while non-institutional investors and qualified institutional buyers recorded stronger participation.
NSE IPO GMP Today: ₹48 or Around 3%
The NSE IPO grey market premium is currently hovering around ₹48, which represents roughly a 3% premium over the upper issue price of ₹1,785.
| Particular | Details |
|---|---|
| IPO Price Band | ₹1,700–₹1,785 |
| Current GMP | Around ₹48 |
| GMP Percentage | Around 3% |
| Indicative Listing Price | Around ₹1,833 |

| Minimum Investment at ₹1,785 | ₹14,280 |
At the upper end of the price band, adding the ₹48 GMP gives an indicative price of approximately ₹1,833. This is only a grey-market indication and should not be treated as a guaranteed listing price.
NSE IPO Subscription Status
The issue had already crossed the overall subscription mark by the end of the second bidding day.
The overall NSE IPO subscription stood at 1.16 times against the 8.86 crore shares available.
Retail Investors
The retail portion received bids equivalent to 72% of the 4.41 crore shares reserved for individual investors.
The retail response therefore remained below full subscription at the end of Day 2.
Non-Institutional Investors
The NII category was subscribed 1.68 times against 1.89 crore shares reserved for the segment.
Qualified Institutional Buyers
QIBs subscribed to 1.53 times the 2.52 crore shares allocated to the category.
NSE IPO: Issue Size and Offer for Sale
The NSE IPO is structured entirely as an Offer for Sale (OFS).
The issue comprises the sale of approximately 12.64 crore existing shares by existing shareholders. Because there is no fresh issue component, the money raised through the IPO will go to the selling shareholders rather than to NSE itself.
The IPO has a price band of ₹1,700 to ₹1,785 per share, with a lot size of eight shares.
At the upper end of the price band, a retail investor needs ₹14,280 for one lot.

Why the NSE IPO Is Attracting Attention
NSE is one of India’s key market infrastructure institutions and operates across several segments of the financial markets.
Its business covers:
- Cash equity trading
- Equity derivatives
- Mutual fund transactions
- Commodity derivatives
- Currency derivatives
- Wholesale debt market
- Interest-rate futures
- Clearing and settlement
- Market data
- Index licensing
The exchange has maintained a leading position in India’s cash market and equity derivatives segments, according to the information cited in the source material.
NSE’s Market Position
As of June 2026, NSE had approximately:
- 132.4 million unique registered investors
- 1,328 trading members
- 3,005 listed companies
- Approximately ₹474.1 trillion market capitalisation of companies listed on the exchange
These figures illustrate the scale of the exchange’s existing market ecosystem.
NSE’s Dominance in Key Market Segments
One of the major factors investors are examining is NSE’s market share.
According to the figures cited in the source report, as of June 2026 NSE accounted for approximately:
| Segment | NSE Share |
|---|---|
| Cash Market Activity | 93% |
| Equity Futures | 99.7% |
| Equity Options | 68.5% |
The exchange’s significant market share is an important part of the IPO’s investment discussion, while the concentration of revenue in transaction-related activities also represents a factor investors need to consider.
Transaction Charges Remain a Key Risk Factor
A significant portion of NSE’s revenue comes from transaction-related charges.
According to the figures cited in the report, transaction charges accounted for 78.7% of NSE’s FY26 revenue, while options contributed 60.2% of revenue from operations during the year.
This makes changes in trading activity, market structure and regulations affecting derivatives particularly relevant to NSE’s future revenue profile.
Equity Options Market Share Has Changed
The source report also highlights a decline in NSE’s share of the equity options market based on premium turnover.
According to figures attributed to YES Securities, NSE’s share declined from:
- 96.86% in FY24
- 74.71% in FY26
- 68.48% in the June 2026 quarter
This trend is one of the factors being watched alongside NSE’s overall market leadership and business scale.
What Does a 3% GMP Mean for NSE IPO?
A GMP of approximately ₹48 against the upper issue price of ₹1,785 translates into an indicative grey-market price of around ₹1,833.
The calculation is:
₹1,785 + ₹48 = ₹1,833
That represents an indicative premium of roughly 2.7%, commonly rounded to around 3%.
However, grey market premium is unofficial and can change before listing. It should not be considered a reliable guarantee of the actual listing price.
NSE IPO: What Investors Are Watching
With the subscription period ending today, investors are primarily watching several factors:
1. Final Subscription Numbers
The final subscription figure could differ substantially from the Day 2 figure of 1.16x as bidding continues on the last day.
2. Retail Participation
The retail category stood at 72% subscribed at the end of Day 2, making the final retail response an important data point.
3. GMP Movement
The GMP has declined from earlier levels and is currently around ₹48, according to reports published on September 21.
4. Regulatory Environment
Because a large part of NSE’s revenue is linked to transaction activity and derivatives, regulatory changes affecting these markets remain relevant to its business.
5. Actual Listing Price
The grey market estimate of around ₹1,833 is not the actual listing price. The market price on listing day can be different.

NSE IPO: Important Investor Note
The GMP figure is based on unofficial grey-market activity and can move quickly depending on market conditions and investor sentiment. It is not a substitute for the IPO’s official financial information or a guarantee of listing gains.
Investors evaluating the NSE IPO should consider the issue structure, valuation, business fundamentals, market-share trends, regulatory risks and their own investment objectives rather than relying solely on GMP.
