NSE – SEBI Clears IPO, Paving the Way for a September Listing

The decade-long wait is finally over. The Securities and Exchange Board of India (SEBI) issued its observation letter for the National Stock Exchange of India's (NSE) initial public offering on September 4, 2026 — clearing the last major regulatory hurdle for what is set to become the largest IPO in Indian capital market history.

The approval came just one day after the Supreme Court of India disposed of SEBI's appeals in the colocation and dark fibre cases, following NSE's ₹1,491.21 crore settlement with the regulator. Sources indicate the price band could be announced as early as next week, with the IPO opening for subscription around September 15 and a BSE listing targeted for September 25.

The IPO structure

NSE's IPO is structured as a 100% Offer for Sale (OFS) of up to 14.89 crore equity shares — approximately 6% of the exchange's paid-up capital. The exchange itself will not raise a single rupee of fresh capital. Every rupee goes to existing shareholders who are selling part of their holdings.

Key sellers include SBI Group, Bank of Baroda, GIC Re, New India Assurance, National Insurance, United India Insurance, and Stock Holding Corporation of India (SHCIL). Notably, Life Insurance Corporation (LIC) — NSE's single largest shareholder with a ~10.72% stake — is not selling. Neither are Premji Invest nor veteran investor Radhakishan Damani. When the most informed, most patient long-term holders choose to hold through a listing rather than cash out, it says something about how they view the asset.

At the widely reported issue size of ~₹30,000 crore, the NSE IPO would surpass Hyundai Motor India's ₹27,859 crore record from 2024 to become India's largest-ever public offering. Kotak Mahindra Capital Company is acting as the coordinating lead manager.

The numbers behind the exchange

NSE is, by any measure, one of India's most profitable businesses. In Q1 FY27 (April–June 2026), the exchange reported net profit of ₹3,120 crore on operating revenue of ₹4,560 crore — representing 7% profit growth and 13% revenue growth year-on-year.

For the full year FY26, NSE posted a PAT of ₹10,302 crore, though reported profitability was pulled down by the ₹1,391 crore provision booked for the colocation and dark fibre settlement, plus a ₹126 crore one-time hit for new Labour Code compliance. Stripping out these one-offs, underlying profitability remained strong, with operating margins historically running above 70%.

The exchange's dominance is near-absolute: over 92% market share in the cash equity segment, near-monopoly in equity futures, and approximately 75–76% share in equity options. Its investor base has crossed 120 million registered investors and 240 million total accounts. NSE also earns substantial income from its ~₹3 lakh crore treasury and investment book, plus listing fees, data feeds, colocation/connectivity charges, clearing and settlement, and index licensing (Nifty 50 and 425+ indices via NSE Indices).

The colocation saga — finally resolved

The NSE IPO has been discussed, delayed, litigated, and rumoured since 2016. The primary reason for the decade-long delay was the colocation controversy — allegations that certain brokers received preferential, faster access to NSE's tick-by-tick data feed through its colocation servers between 2010 and 2014, potentially giving them an unfair trading edge. A related dark fibre case involved allegations about preferential network connectivity.

The resolution came in stages: NSE filed its settlement application with SEBI in June 2025, offering ₹1,388 crore under SEBI's Settlement Regulations 2018. SEBI agreed in principle in January 2026 and issued a no-objection certificate shortly after. NSE provisioned ₹1,391 crore in FY26 and paid ₹1,491.21 crore (including accrued interest) in July 2026. The Supreme Court disposed of SEBI's appeals on September 3, 2026, and NSE received its SEBI observation letter the very next day.

Because the settlement was already fully provisioned, the cash payment is a balance-sheet event — it won't show up as a fresh expense in FY27 results.

Valuation and the unlisted market

NSE shares have been trading in the unlisted market at approximately ₹1,950–2,050 per share, implying a market capitalisation of roughly ₹5 lakh crore. At FY26 EPS of approximately ₹41.62, this translates to a trailing P/E of around 47–49x.

For context, listed peer BSE currently trades at approximately 65x earnings — a premium multiple despite being significantly smaller (~3.4x smaller by revenue, ~4x by profit). Analysts estimate NSE's fair IPO price in the range of ₹1,970–2,100 per share, with some noting that pricing below the prevailing unlisted market rate (as was done with the SBI AMC IPO) would ensure healthy post-listing demand.

Early shareholders stand to make extraordinary returns. Many institutional holders — including SBI — acquired NSE stock at costs under ₹1 per share decades ago. At current valuations, the IPO represents a multi-thousand-fold return on their original investment.

What to watch

The official price band, expected next week, will set the tone for institutional and retail sentiment. Key variables include the anchor investor response, the quantum of retail oversubscription, and whether the IPO is priced at a discount or premium to the unlisted market price. The broader market environment — and the positioning of the NSE IPO relative to other anticipated mega-listings like Jio Platforms — will also influence timing and demand.

For the Indian capital markets ecosystem, the NSE listing is more than just another IPO. It offers investors a direct way to participate in the growth of India's financial market infrastructure itself — the rails on which every equity, derivative, and index trade in the country runs.
