MUMBAI / NEW DELHI, SEPTEMBER 21, 2026 — During intraday trade on Monday, September 21, the National Stock Exchange (NSE) initial public offering (IPO) maintained steady momentum on its third day of bidding. While the retail portion has achieved full subscription, cooling sentiment in the grey market has led analysts to project a more conservative listing performance than initially anticipated.

Grey Market Premium (GMP) Tracking
According to the latest tracking data from Chittorgarh and IPOWatch, the Grey Market Premium (GMP) for the NSE IPO has witnessed a notable softening. As of Monday, September 21, the premium stands at approximately 3% over the upper price band. This indicates a shift toward a more cautious listing sentiment compared to earlier unlisted market expectations. The trend is currently classified as Soft/Muted.
In-Depth Analysis: Subscription Trends & Market Sentiment
Data compiled by Moneycontrol and The Economic Times confirms that the NSE IPO has seen a steady, if not explosive, intake. By the afternoon of Day 3, the total subscription crossed the 2x mark, driven largely by the retail segment which is now fully covered. The Qualified Institutional Buyer (QIB) and Non-Institutional Investor (NII) portions are expected to see a late-stage surge before the bidding window closes.
Institutional & Retail Appetite
Brokerage research from Motilal Oswal suggests that while the NSE’s market dominance is a long-term moat, the massive ₹16,500 crore Offer for Sale (OFS) size may be weighing on immediate listing gains. The exit of several large selling shareholders, who are poised to realize significant gains, remains a key focal point for fundamental analysts.

Balanced Investor Framework (Bull vs. Bear)

Investment Verdict

Risk Level: Medium — High regulatory sensitivity balanced by a monopoly-like business model.
Key Watch Point: Final QIB subscription figures on the last day to gauge institutional conviction.
Frequently Asked Questions
Should investors apply for the NSE IPO based on current valuations?
While NSE is a fundamentally strong entity with a dominant market position, the current 3% GMP suggests that listing gains may be marginal. Investors should focus on the long-term growth of the Indian capital markets rather than short-term listing arbitrage.
What is the Grey Market Premium (GMP) and expected listing sentiment for NSE?
The GMP currently tracks at approximately 3%, indicating a muted debut. According to data from Chittorgarh and Moneycontrol, this softening reflects a cautious stance among grey market participants ahead of the Thursday listing.
What are the primary balance sheet strengths and risk factors for NSE?
NSE’s primary strength lies in its massive operating cash flows and technological moat. However, the primary risk factors include evolving SEBI regulations and the potential impact of the large ₹16,500 crore OFS on secondary market liquidity post-listing.
