For nearly a decade, the National Stock Exchange has helped thousands of companies go public, while quietly failing to do the one thing itself. That is now changing.
In today's FirstScroll, we unpack the long, strange road to the NSE's own IPO, why it took ten years, and what the listing of India's biggest exchange really means.
The Story
Think about what a stock exchange actually does. It is the marketplace where companies sell shares to the public and where investors buy and sell those shares every day. The National Stock Exchange of India, the NSE, is by far the largest such marketplace in the country. If you own a single share of any Indian company, there is a very strong chance it trades on the NSE.
Now here is the irony that has hung over the NSE for nearly ten years. The exchange that helps everyone else go public has not been able to go public itself.
That is finally about to change.
In a sequence of decisions over the past few months, the path has been cleared. On January 30, 2026, the Securities and Exchange Board of India, or SEBI, the market regulator, issued the NSE a no-objection certificate, or NOC, for its IPO. Then, on February 16, 2026, the Delhi High Court dismissed a legal petition that had challenged that approval, removing the last major obstacle. The NSE has since reconstituted its IPO committee and appointed Rothschild and Co as an independent adviser for the process.
After almost a decade of false starts, India's biggest stock exchange is genuinely heading for its own listing.
To understand why this is such a big deal, you first need to understand why it took so long.
For the uninitiated, the NSE first filed its draft IPO papers all the way back in October 2016, aiming to raise around ₹10,000 crore. It looked routine at the time. Then it ran into a scandal that would consume the next several years, known as the co-location case.
Here is what that case was about, simply. A stock exchange runs on computer servers. Some trading firms, particularly high-frequency traders who profit from tiny price differences in fractions of a second, pay to place their own servers physically close to the exchange's servers. That is called co-location, and it is legal. The problem at the NSE was an allegation that certain brokers were getting preferential access. Because of how the exchange's systems were set up, some traders allegedly received market data a crucial split-second before others. In high-frequency trading, a split-second is everything. It is the difference between a guaranteed profit and a fair race.
This triggered years of investigations by SEBI. In 2019, SEBI imposed a significant penalty on the NSE for governance and systems lapses. The IPO was effectively frozen. You cannot ask the public to buy shares in a company while its core fairness is under official investigation.
So how did the logjam finally break? Through settlement.
In June 2025, the NSE filed settlement applications with SEBI for the co-location and related dark fibre cases. Under SEBI's settlement mechanism, a company can resolve a long-running case by paying a sum and making fixes, without a never-ending legal battle. The NSE made provisions of around ₹1,300 crore toward these settlements. Once SEBI was satisfied with the remedial steps the NSE had taken on governance and systems, it granted the NOC.
There was one more hurdle. A former judicial officer, K. C. Aggarwal, filed a petition in the Delhi High Court challenging SEBI's NOC, raising concerns about how the NSE handled certain derivatives adjustments. But on February 16, the court declined to entertain the petition, with the judge observing that the plea appeared to have been filed only to stall the IPO of the country's largest stock exchange. The court also noted it lacked territorial jurisdiction, since both SEBI and the NSE are headquartered in Mumbai.
With that, the road was clear.
So what will this IPO actually look like?
A few features are worth understanding.
First, it is expected to be an Offer for Sale, or OFS. This is an important distinction. In a normal IPO, a company issues brand new shares and the money raised goes into the company to fund growth. In an OFS, no new shares are created. Instead, existing shareholders sell a part of their holdings to the public, and the money goes to those selling shareholders, not to the company. The NSE is choosing an OFS because, frankly, it does not need the cash. It is a highly profitable institution and does not require fresh capital to run or expand. The IPO is about giving existing shareholders a way to sell and about getting the exchange listed, not about raising funds.
Second, the scale is large. Reports have estimated a dilution of around 4% to 5% of the exchange, which could translate into an IPO size in the broad range of ₹21,000 crore to ₹24,500 crore. That would place it among the largest public issues in Indian market history. The exact size and pricing will only be known when the formal documents are filed.
Third, the timeline is a process, not an event. NSE management has indicated it needs roughly four to five months to prepare and file the Draft Red Herring Prospectus after the NOC, followed by SEBI's review, roadshows, and final approvals. Putting it together, the listing is widely expected somewhere in late 2026 or early 2027, subject to market conditions.
So why does the listing of a stock exchange matter to you, beyond being a milestone?
Three takeaways.
One, an exchange is a genuinely unusual and attractive kind of business. Most companies have to fight hard for every customer and worry constantly about competitors. A large stock exchange has a different economic character. It earns fees on transactions, on listings, on data, and on technology services. As trading activity in India grows, as more companies list, and as more retail investors enter the market, the exchange earns more, largely without having to spend proportionally more. The NSE's strong profitability reflects this. For investors who eventually get the chance to buy in, a stock exchange is, in effect, a way to bet on the growth of Indian capital markets as a whole, rather than on any single company.
Two, there is a fascinating structural quirk here, and it is worth pausing on. Once listed, the NSE will be a publicly traded company whose shares trade on a stock exchange. But the NSE is itself a stock exchange, and it is also a regulated market infrastructure institution overseen by SEBI. This raises real questions about oversight and conflict of interest, which is part of why the governance bar for this listing has been set so high, and why SEBI spent years insisting on remedial action before clearing it. The scrutiny was not bureaucratic delay for its own sake. An exchange asking the public to become its shareholders has to be held to an unusually high standard of fairness, because fairness is the entire product it sells.
Three, watch this as a signal of where Indian markets are in their cycle. The NSE choosing to list now, and a wave of other large companies lining up IPOs through 2026, tells you something. Companies and their existing shareholders list when they believe there is strong investor appetite and reasonable valuations available. The NSE IPO is, in a sense, a vote of confidence in the depth and maturity of India's own capital markets, the very markets the NSE operates.
But let's be clear about what this listing is not.
It is not yet done. An NOC and a cleared legal challenge are major steps, but the DRHP still has to be filed, SEBI still has to review it, and the final listing depends on market conditions at the time. IPO timelines, especially for something this large and this scrutinised, can move. A late-2026 or early-2027 listing is the expectation, not a guarantee.
And it is not a fundraising exercise for the NSE. Because it is structured as an Offer for Sale, the IPO will not put new money into the exchange's own coffers. It is a liquidity event for existing shareholders and a listing milestone for the institution, nothing more. Anyone evaluating it should understand they would be buying shares from current owners, not funding the exchange's expansion.
Step back, and there is a quietly fitting story here. The NSE was created in the early 1990s precisely to modernise and clean up Indian stock trading, to replace an opaque, broker-dominated system with a transparent, electronic, screen-based market. It largely succeeded, and in doing so it became the backbone of Indian equity trading.
Then it spent nearly a decade unable to list itself, held back by a scandal about fairness, the one thing an exchange cannot afford to be seen failing at. The long road to this IPO, the investigations, the penalty, the settlements, the governance overhaul, was in effect the NSE being forced to hold itself to the same standard it sets for every company that lists on it.
That is a slow and frustrating process. But it is also, arguably, the system working as intended. The marketplace finally gets to enter its own marketplace, only after proving it deserves to be there.
Until next time…
