Introduction

The National Stock Exchange of India (NSE) , the country's largest and one of the world's most valuable stock exchanges ,is finally going public after years of regulatory delay. Its Rs. 22,569 crore initial public offering opened for subscription today, September 17, 2026, marking one of the biggest listings in Indian capital-market history. 

The catch: this isn't NSE raising fresh capital to grow its business. It's a pure Offer for Sale, meaning existing shareholders, including SBI, LIC, and several private equity and pension investors,are simply cashing out part of their stakes while NSE itself pockets nothing directly from the issue. 

With the exchange commanding roughly 93% of India's cash-market share and virtually the entire equity derivatives market, investors are watching closely to see whether this listing captures the same fervour as recent blockbuster IPOs, or whether rich valuations and a shaky grey market premium temper the enthusiasm.

What's Changed for NSE Today

The National Stock Exchange (NSE) IPO opened at 10 am on September 17 and will close September 21, 2026. Here's what's fresh since yesterday:moneycontrol

1. GMP has been volatile throughout the day. After trading near Rs.145-165 on September 16, the grey market premium dipped to around Rs.125 in the early hours of September 17, a sharp fall from the Rs.218 level seen on September 11, before climbing back through the day.By late morning, the live tracker showed GMP near Rs.155 (an 8.7% implied gain), while the Economic Times reported the latest GMP at approximately 9.4% by early afternoon, valuing NSE at 42.9 times earnings versus rival BSE's 53.3 times.Given how quickly these numbers are shifting, from Rs.125 to Rs.155 to a 9.4% implied gain within a few hours, treat any single GMP figure as a point-in-time snapshot rather than a fixed data point, and always check the timestamp on the source before quoting it.

2. Day 1 subscription is underway. The issue was subscribed 16% within an hour of opening, with retail bids at 20%, NII bids at 25%, and the employee quota at 41%. The QIB (institutional) category had not logged bids yet at that stage, which is typical since institutions usually bid closer to the closing date. (Source: Ndtvprofit dated September 2026)

3. The anchor book is confirmed at Rs.6,746.2 crore, higher than earlier media estimates of Rs.6,000-6,250 crore. NSE allotted 3.77 crore shares to 189 anchor investors the top price of Rs.1,785.

4. LIC is the largest anchor investor, picking up shares worth Rs.465.3 crore, even though it is not selling any of its existing 10.72% stake through the OFS. Other marquee anchor participants include Norges Bank, Fidelity, the Abu Dhabi Investment Authority (ADIA), Government Pension Fund Global, the Monetary Authority of Singapore, Nippon Life and HDFC Life.

Who Is Selling NSE Shares? Updated Shareholder List

The final RHP confirms the updated list of selling shareholders, with State Bank of India (SBI) remaining the largest seller:

Notably, Life Insurance Corporation of India (LIC), which holds a 10.72% stake in NSE, has opted out of selling any shares in this IPO. National Insurance Company, which appeared as a seller in earlier drafts, is no longer part of the final selling shareholder list.

Conclusion

The NSE IPO is a rare chance for investors to acquire a stake in the country’s leading stock exchange. The price band has been fixed at Rs.1,700-1,785 and the minimum lot size has been kept at affordable Rs.14,280. The strong anchor backing from LIC, Fidelity and ADIA indicates institutional confidence, while the declining GMP of about Rs.125 indicates moderate listing-gain expectations. 

Brokerage views are split between caution on valuation and optimism on long-term, so the subscribe decision should be made on fundamentals not just gray market signals.
