NSE IPO Listing September 24: GMP & Analyst Views

NSE IPO Listing on September 24: Analysts Weigh Prospects of a Subdued Debut

September 21, 20265 Mins Read

The NSE IPO is heading toward its proposed September 24 listing, with grey market indicators pointing to a more measured debut than the premium levels seen earlier in the IPO cycle. Analysts tracking the issue have noted that the cooling grey market premium suggests expectations of a large listing gain have moderated.

The IPO, which carries a price band of ₹1,700–₹1,785 per share, is a ₹22,561.57 crore offer for sale (OFS) involving 12.64 crore shares. Since the issue is entirely an OFS, NSE itself will not receive proceeds from the IPO.

Grey Market Premium Cools Ahead of Listing

The NSE IPO’s grey market premium has declined significantly from levels seen earlier in September.

PL Capital reported a GMP of around ₹70 per share on September 21, implying an estimated price of approximately ₹1,855 at the upper end of the IPO price band. That represents a premium of around 3.92% over the ₹1,785 issue price.

Grey market premium is an unofficial indicator and does not guarantee the actual listing price. The movement nevertheless provides a snapshot of changing expectations ahead of the listing.

Earlier in the IPO process, the GMP had been considerably higher. India Today reported a GMP of ₹218 on September 11, which subsequently declined to ₹125 by September 17.

Analysts Point to Moderated Listing Expectations

The cooling GMP has led analysts to discuss the possibility of a relatively subdued listing.

According to Moneycontrol, Ponmudi R, CEO of Enrich Money, said the declining GMP suggests expectations of a large listing gain have moderated. He also noted that the listing could be relatively muted if broader market sentiment remains subdued.

At the same time, analysts have cautioned against treating GMP as a standalone assessment of NSE’s underlying business.

The distinction is important because the grey market reflects short-term expectations around the listing, while NSE’s long-term business performance depends on factors including trading volumes, market share, regulatory changes and growth in non-transaction revenue.

NSE’s Market Position Remains a Key Factor

NSE continues to hold a dominant position across several segments of India’s capital markets.

According to data cited by Moneycontrol for the three months ended June 2026, NSE held a 93.05% share of the cash market, 99.72% of equity futures, and 68.48% of equity options based on premium turnover.

The exchange also had a large investor and trading ecosystem ahead of the IPO. India Today, citing IPO research, reported that NSE had 261.36 million registered investor accounts and 132.37 million unique registered investors as of June 30, 2026.

Derivatives Revenue Remains an Important Watchpoint

One of the key issues for investors following the IPO is NSE’s dependence on transaction-related revenue, particularly from derivatives.

NSE’s FY26 revenue from operations stood at ₹16,601.31 crore, while transaction charges accounted for the majority of operating revenue. Equity options represented approximately 60.2% of operating revenue, according to analysis of the company’s IPO documents.

Changes in derivatives regulations and taxation have also affected trading activity.

The regulatory framework for equity-index derivatives has undergone several changes, including higher contract values and changes to expiry structures. From April 2026, the securities transaction tax on futures was also increased from 0.02% to 0.05% of contract value, while the rate on options increased from 0.10% to 0.15% of premium value.

These developments make derivatives volumes and transaction revenue important metrics to monitor following the listing.

IPO Subscription Shows Strong Institutional Participation

Despite the cooling GMP, the IPO has continued to attract substantial demand during the subscription period.

As of September 21, PL Capital reported overall subscription of 2.38 times, with QIB subscription at 3.75 times, NII subscription at 3.74 times and retail subscription at 1.03 times as of 1:11 p.m.

Goodreturns separately reported overall subscription at 2.65 times later in the day, highlighting continued bidding activity during the final session.

The difference between subscription data points reflects the timing of the respective updates during the final bidding day.

What Investors Will Watch After Listing

Once NSE begins trading publicly, investors will have several factors to track beyond the initial listing price.

These include:

- Trading volumes: Changes in cash and derivatives activity could directly affect transaction revenue.

- Options concentration: Equity options remain a significant contributor to NSE’s operating revenue.

- Regulatory changes: Further changes to derivatives rules or transaction taxes could influence market participation.

- Competitive dynamics: BSE’s growing activity in certain derivatives segments could affect NSE’s market share.

- Non-transaction revenue: Data services, index licensing and listing services could become increasingly important to revenue diversification.

- Profitability: Investors will track whether NSE can maintain its historically strong margins amid changing trading patterns.

NSE IPO Listing: The Bigger Picture

The NSE IPO has generated significant market attention because of the exchange’s dominant position in India’s capital markets. However, the expected listing premium has moderated as the IPO approaches its September 24 debut.

The current GMP provides an unofficial indication of market expectations, but it should not be treated as a forecast of the actual listing price. The longer-term performance of NSE as a listed company will depend on trading activity, regulatory developments, competitive positioning, and its ability to sustain revenue and profitability.

With allotment expected on September 22 and listing scheduled for September 24, investors will soon have actual market-price data to assess how the IPO’s valuation compares with its public-market performance.
