NSE Spent a Decade and ₹1,491 Crore Getting to the Listing Bell. The Stock Fell the Very Next Day

On September 24, the National Stock Exchange — the venue where nearly every Indian equity and derivatives trade actually clears — became a stock you could buy on its own exchange, one of the world's biggest by trading volume finally trading itself. Shares opened at ₹1,800 on the BSE, a premium of just 0.84% over the ₹1,785 issue price. By the following afternoon, they were changing hands at ₹1,806.60, down 0.63% on the day. NSE had already touched a 52-week low of ₹1,790 that same week — barely above what anyone paid to get in.

For context: when BSE itself went public in February 2017, its shares closed the debut day roughly 33-35% above the issue price. NSE is the larger, more dominant of India's two exchanges by a wide margin, and its own listing barely moved.

A decade in the waiting room

NSE first filed for an IPO in 2016, seeking to raise nearly ₹10,000 crore through an offer for sale. It never got there. A colocation scandal — brokers alleged to have received preferential, faster access to NSE's trading servers, giving them a speed edge on virtually every other participant — blew up shortly after, and SEBI told the exchange to withdraw its listing application while the matter was investigated. In 2019, SEBI fined NSE ₹1,100 crore (₹11 billion) for failing to provide members equitable access to its systems. A separate dispute over "dark fibre" networking access compounded the overhang.

What actually cleared the path, nearly a decade later, was money. NSE filed settlement applications with SEBI in June 2025 proposing to pay roughly ₹1,387 crore to close both matters. SEBI came back with revised terms in March 2026, and the two sides landed on a final figure of ₹1,491.21 crore — ₹1,223.56 crore for the colocation case, ₹267.65 crore for the dark-fibre dispute. NSE had already provisioned ₹1,391.21 crore for this in its FY25-26 accounts, and paid the full ₹1,491.21 crore to SEBI on July 31, 2026. The Supreme Court disposed of the remaining pleas around it in mid-September, and SEBI cleared the IPO to proceed days later.

That is, in effect, the price of admission: NSE didn't resolve the colocation case on the merits so much as it paid to make the merits stop mattering to its listing timeline.

Why buyers showed up and the stock still shrugged

The demand side of the IPO was not the problem. The ₹22,569 crore issue — entirely an offer for sale by existing shareholders, so NSE itself raised no fresh capital from it — was subscribed 5.71 times, drawing bids worth roughly ₹90,300 crore against shares worth ₹22,569 crore on offer. The anchor book alone raised about ₹6,746 crore from institutions including LIC, Goldman Sachs and Fidelity. Brokerages have stayed bullish since: Emkay Global initiated coverage with a Buy rating and a ₹2,050 target, PL Capital rated it Accumulate at ₹1,950 — both comfortably above the ₹1,785 issue price.

None of that produced a pop. A few things explain the gap between enthusiastic bidding and a flat debut:

• It's a pure offer-for-sale. Every rupee paid at the IPO went to existing shareholders cashing out, not into NSE's own balance sheet. A listing that raises no growth capital reads differently to the market than one that does — there's no new business being funded, just existing ownership changing hands at a price the company itself had no say in setting beyond the band.
• A decade of anticipation was already priced in. By the time the IPO opened, NSE's unlisted shares had traded in grey and pre-listing markets for years on the assumption this would eventually happen. A 5.71x subscription on an issue priced at the top of its ₹1,700-1,785 band suggests buyers paid up for certainty, leaving less room for a debut-day surprise.
• The settlement doesn't erase the governance question, it just closes the file. NSE bought its way past the colocation matter rather than being cleared of it, and a company that just wrote a ₹1,491 crore cheque to make a preferential-access scandal go away is not the same story, to a market participant weighing it fresh, as one that never had the scandal at all.
• Its core revenue line is shrinking, and buyers can read a prospectus. NSE's own FY26 numbers, disclosed ahead of the IPO, show revenue and profit both down year-on-year, driven by an 18% fall in F&O turnover after SEBI's 2024 curbs on retail derivatives trading. A subscriber weighing 5.71 times oversubscription against a business whose most profitable segment is under active regulatory pressure has reason to bid cautiously even while still bidding.
• NSE listed into a falling market. The exchange's debut landed inside the same stretch that has produced the Nifty's longest weekly losing run since the 2020 Covid crash — seven straight weeks lower, with foreign investors pulling out capital faster than domestic funds have been able to absorb it. A muted listing-week performance during a market-wide risk-off stretch says less about NSE specifically than a flat debut in a rallying market would.

The business the market is actually pricing

Strip away the settlement and the listing-day theatrics, and NSE is a business whose own numbers were already moving in the wrong direction before it rang the bell. Revenue fell to ₹16,601 crore in FY26 from about ₹17,141 crore in FY25, and net profit dropped roughly 15% to ₹10,302 crore from about ₹12,188 crore. Transaction fees — the toll NSE collects on every trade that clears through it — brought in ₹13,057 crore, down 4% from ₹13,636 crore, and made up 78.65% of operating revenue. Clearing and settlement income fell harder, down 22% to ₹251 crore from ₹321 crore.

The reason all of that slipped is concentrated almost entirely in one place: options trading. Derivatives account for about 69% of NSE's FY26 revenue, and options alone — mostly the short-dated weekly index contracts that became a genuine retail obsession over the last several years — contributed roughly ₹9,998 crore, or 60% of the total. F&O turnover fell 18% in FY26, and that decline traces directly back to SEBI itself. In October 2024, the regulator rolled out six measures explicitly designed to curb retail speculation in index derivatives: raising the minimum contract size from about ₹5 lakh to ₹15-20 lakh, tightening margin requirements, cutting weekly expiries to one benchmark index per exchange, requiring upfront collection of the full option premium from buyers, and adding intraday position monitoring. The effect showed up fast. Combined index options volume on NSE and BSE fell 52% in FY26 — 62.8 billion contracts against 131.4 billion the year before — and the number of unique retail traders in F&O fell about 20%, to 78.6 lakh from 98.1 lakh. India's share of global equity options premium, which had reached roughly 35% of the US market at its 2024 peak, slipped to about 20% by 2025.

That is the irony sitting underneath the listing: the single regulator whose clearance NSE spent a decade waiting on, and just paid ₹1,491.21 crore to get past, is the same regulator that has spent the last two years deliberately shrinking the trading activity NSE depends on for roughly six of every ten rupees it earns. A buyer weighing NSE's IPO wasn't just pricing in a scandal settlement and a flat-to-down debut week — they were pricing a company whose largest profit engine has a governor on it, installed by the same authority that decides what NSE is allowed to do next.

The irony of going public

The scandal that delayed this listing by roughly a decade is now, because of the listing, a matter of permanent public record rather than a regulatory file NSE could quietly settle and move past. As a listed company, NSE owes shareholders quarterly disclosure, is subject to public shareholder votes, and will have every future SEBI interaction read by analysts and covered by the same financial press that covers the exchanges it operates. The IPO didn't just monetise a decade-old asset for its existing shareholders — it converted NSE from a quasi-monopoly answerable mainly to its regulator into one that also has to answer to a stock price, on a day when that stock price already told it the market isn't inclined to be generous.
