After years of regulatory hurdles and delays, India's largest stock exchange is finally ready to enter the stock market.
The National Stock Exchange of India (NSE) will open its long-awaited IPO for subscription on September 17, seeking a valuation of about $46 billion. The issue will be entirely an offer for sale (OFS), so NSE itself will not receive any fresh capital.
The price band has been fixed at ₹1,700-1,785 a share. The IPO will close on September 21 and the shares are expected to list around September 24.
For investors, this is more than another large IPO. NSE is the dominant platform for India's equity and derivatives trading, and its listing will give the public a chance to own a stake in one of the country's most strategically important financial-market businesses.

NSE has reduced the issue size by more than 15% from the 14.89 crore shares proposed earlier. Some existing shareholders have cut the number of shares they plan to sell.
Because the IPO is an OFS, the proceeds will go to the selling shareholders rather than to NSE.
NSE was established in 1992, following a period marked by major stock-market scandals and concerns over the fragmented system of regional exchanges.
The idea was to create a modern, technology-driven national exchange with greater transparency and wider access. The initial investors included major financial institutions such as Life Insurance Corporation of India, IDBI and State Bank of India.
More than three decades later, NSE has become the dominant force in India's capital markets. According to exchange data, NSE had more than 2,000 registered members and more than 2,200 listed companies as of June 17. The companies listed on the exchange had a combined market capitalisation of about $5 trillion.
NSE's biggest strength is its market dominance. The exchange has about 95% of India's cash-equity market and around 75% of the equity-derivatives market, according to its disclosures.
Its dominance is even more striking in global derivatives trading. NSE is the world's largest derivatives exchange by the number of contracts traded. Data from the World Federation of Exchanges showed that it accounted for roughly 89% of global stock-index options volumes in 2025.
The rapid growth of options trading in India has been a major driver of NSE's business.
NSE reported a profit of ₹10,300 crore for the financial year ended March 2026, although this was about 15% lower than the previous year.
Its revenue has nevertheless grown dramatically. Revenue more than doubled between April 2019 and April 2026 to about ₹18,700 crore. The key driver has been the explosion in derivatives trading.
More than 80% of NSE's total income comes from transaction-related revenue, with derivatives accounting for the bulk of this income.
That is both a strength and a risk.
High trading volumes can generate enormous profits during periods of strong market participation. But a sharp fall in trading activity, particularly in derivatives, could have a significant impact on revenue.
Another point investors should consider is NSE's revenue mix. The world's major exchanges typically derive only around 40% of their income from transaction fees. The rest comes from businesses such as market data, technology, indices and other services.
NSE, by contrast, remains heavily dependent on transaction revenue. For investors, this raises an important question: Can NSE diversify its income beyond trading fees as it grows?
A stronger contribution from data, technology and other non-transaction businesses could make its earnings more stable over the long term.
NSE's first attempt to go public was planned for 2016. But the IPO was held up by regulatory investigations into allegations involving preferential access to certain trading members and other governance issues.
In 2019, SEBI imposed a penalty of about ₹1,100 crore on NSE. The exchange and the regulator have been involved in prolonged legal proceedings over the matter.
NSE has now proposed an out-of-court settlement involving a payment of about $157 million. The proposal is under SEBI's consideration, according to the IPO documents.
The long delay is an important part of NSE's IPO story. Investors therefore need to consider not only the exchange's strong market position and profitability, but also its regulatory and governance history.
For retail investors considering the IPO, five factors deserve attention:
Valuation: At about $46 billion, is NSE's valuation justified by its earnings and growth prospects?
Trading volumes: NSE's profits are closely linked to transaction activity, particularly derivatives.
Market dominance: Its commanding share gives NSE significant competitive strength.
Regulation: Changes in rules governing derivatives and retail participation could affect future earnings.
Revenue diversification: Greater income from data, technology and other businesses could reduce dependence on trading fees.
NSE's IPO marks the public-market debut of an institution that sits at the heart of India's investment economy.
Its near-dominant market share, huge trading volumes and strong profitability make it an unusual IPO. At the same time, its dependence on transaction income and its long regulatory history mean investors should not look at the exchange simply as a "must-own" business.
The IPO may generate enormous interest among retail and institutional investors. But the crucial question will remain the same: Is the price right for the business?
The answer will depend less on NSE's brand name and more on its valuation, future earnings growth and ability to maintain its market dominance while diversifying its revenue.
The lot size is eight shares, and investors can bid in multiples of eight.
At the lower price of ₹1,700, one lot will cost ₹13,600. At the upper price of ₹1,785, it will cost ₹14,280.
State Bank of India is the biggest seller, offering up to 1.59 crore NSE shares. Other major sellers include:
Canada Pension Plan Investment Board: 1.18 crore shares
Aranda Investments (Mauritius): 1.12 crore shares
MS Strategic (Mauritius): 1.10 crore shares
New India Assurance Company: 1.05 crore shares
SBI Capital Markets: 87.8 lakh shares
Several shareholders have reduced the number of shares they plan to sell. These include SBI, MS Strategic, Bank of Baroda, Stock Holding Corporation of India and General Insurance Corporation of India.
National Insurance Company, which was earlier part of the proposed OFS, has exited the issue.
The IPO allocation provides for:
Retail investors: at least 35%
Non-institutional investors: at least 15%
Qualified institutional buyers: up to 50%
This gives retail investors a sizeable allocation, although the actual allotment will depend on subscription demand.
This is where retail investors need to look beyond the NSE brand.
NSE is arguably one of India's most important financial-market businesses, with a dominant position in several segments of the country's capital markets. Its IPO is therefore attracting enormous interest.
But a great business is not automatically a great investment at any price.
At ₹1,785 a share, investors should examine NSE's valuation against its earnings, growth prospects, profitability, market position and regulatory risks.
The fact that the minimum investment is only ₹14,280 should not be confused with affordability in valuation terms.
The NSE IPO is likely to be one of India's biggest and most closely watched market events of the year.
For retail investors, the entry ticket is relatively small — ₹14,280 for one lot at the upper end of the price band.
But the more important question is not “Can I afford one lot?” It is “Am I getting enough value for my money?”
NSE is a high-profile business with a powerful position in India's financial markets. That makes the IPO worth watching. But investors should make the final decision based on valuation and long-term prospects, rather than the excitement surrounding the listing.
