NSE's ₹22,569-Crore IPO Opens This Week, Ending a Decade-Long Wait to Take India's Largest Exchange Public

Nearly ten years after it first filed papers to go public, the National Stock Exchange of India will finally face investors this week. The bourse's initial public offering opens for public subscription on Wednesday, September 17, with anchor investors placing bids a day earlier, and closes on September 21. The offer is worth about ₹22,569 crore at the top of the price band, making it one of the largest public issues in Indian history, and it values the country's biggest exchange at roughly ₹4.42 lakh crore, or about $46 billion. In a twist of market structure, NSE's shares will list on September 24 on its old rival, the BSE, because Indian rules do not allow an exchange to list on itself.

A pure exit for early shareholders

The IPO is entirely an offer for sale of 12.64 crore equity shares in a price band of ₹1,700 to ₹1,785, according to Millennium Post. Not a rupee of fresh capital goes to the exchange itself; every share sold belongs to existing investors. Ten shareholders are selling, led by the State Bank of India and the Canada Pension Plan Investment Board, alongside Temasek's Aranda Investments (Mauritius), Morgan Stanley's MS Strategic (Mauritius), The New India Assurance Company, SBI Capital Markets, Bank of Baroda, Stock Holding Corporation of India, General Insurance Corporation of India and United India Insurance.

Retail investors can bid for a minimum lot of eight shares, which works out to ₹14,280 at the upper band. Half the issue is reserved for qualified institutional buyers, 35 per cent for retail investors and 15 per cent for non-institutional investors, with additional reservations of ₹70 crore for employees and ₹71 crore for existing NSE shareholders, per Multibagg's Market Pulse analysis of the red herring prospectus. A syndicate of around twenty book-running lead managers, including Kotak Mahindra Capital, JM Financial, Morgan Stanley India, Citi and HSBC, is marketing the issue, with MUFG Intime India acting as registrar.

A listing delayed by a decade of scandal

NSE first filed a draft red herring prospectus on December 28, 2016, for an issue then planned at about ₹10,000 crore. That attempt collapsed under the weight of the co-location controversy, in which some brokers were alleged to have received tick-by-tick market data fractions of a second before other participants by exploiting the exchange's co-located servers. A related "dark fibre" matter involved allegations that select brokers obtained preferential connectivity to the exchange's network.

The endgame came only this year. According to Outlook Business, SEBI cleared a settlement of ₹1,491.21 crore on July 30, 2026, comprising ₹1,223.56 crore for the co-location case and ₹267.65 crore for the dark fibre matter. NSE had first proposed a settlement of ₹1,387.39 crore in June 2025 and revised the offer upward in March 2026; it had already deposited ₹776.47 crore and paid the balance of ₹714.74 crore. Earlier, in 2023 and 2024, the Securities Appellate Tribunal had set aside SEBI's disgorgement orders while directing a ₹100 crore contribution to the Investor Education and Protection Fund, and SEBI's appeals in the matter remain pending before the Supreme Court. The regulator issued its no-objection certificate for the listing on January 30, 2026, and NSE filed its fresh draft prospectus on June 18, 2026.

The business investors are buying

The numbers explain why the issue is so keenly awaited. For the financial year 2025-26, NSE reported total revenue of ₹16,601 crore and a profit after tax of ₹10,302 crore, a margin of about 62 per cent, according to Multibagg's review of the prospectus. Momentum has continued into the current year: Millennium Post reported revenue from operations of ₹4,560 crore and net profit of ₹3,121 crore for the quarter ended June 30, 2026. The exchange serves a registered investor base of roughly 13 crore, and earns from transaction charges, co-location and connectivity services, data feeds, clearing and licensing of its Nifty family of indices.

The price is not cheap. At the upper band, the offer values NSE at about 43 times its FY26 earnings per share of ₹41.62 and nearly 14 times book value, though the exchange is debt-free with a return on equity of about 33 per cent. Analysts tracking the issue flag familiar risks: the exchange's heavy dependence on equity derivatives volumes, the possibility of further regulatory tightening on options trading through changes to expiry rules, securities transaction tax or margin norms, and the unresolved Supreme Court appeals.

A milestone for the primary market

The offer also carries symbolic weight for India's primary market. Business Today reported that the NSE issue will take total IPO fundraising in 2026 past the ₹1 lakh crore mark, the third year in a row and only the fourth time ever that the milestone has been crossed, after 62 mainboard IPOs raised ₹73,673.54 crore between January and August. The announcement was felt immediately by the competition: BSE's own shares fell about 3 per cent after NSE fixed its price band, Business Today noted.

Share allotment is expected on September 22, with trading to begin on September 24. Whether the stock's debut rewards the patience of shareholders who waited a decade for this listing, the offer closes one of the longest and most contentious chapters in the history of Indian market infrastructure.
