NSE readies to list on a tight leash

The long-awaited IPO of the National Stock Exchange of India has been almost a decade in the making. Repeatedly stalled by governance issues and regulatory scrutiny, in theory the listing should mark a fresh start for the country’s dominant bourse.

In practice, there is little sense of reset or regeneration. If anything, it seems more like a long messy chapter has been cleaned up enough for existing investors to exit. The IPO is expected to be an offer for sale, with no fresh capital raised.

Media reports suggest only 4–5% will be sold—enough to list, but not to broaden the investor base or be included in major indices—making this look like a controlled, low-dilution cash-out for investors in India’s longest-running IPO-in-waiting. It also raises the question of whether years of unofficial trading in the grey market have already set the price.

No prospectus has been issued and a listing is not expected before year-end. But already the priority seems clear: get the listing over the line.

Keep calm and carry on

Ten years after NSE applied to go public, the Securities and Exchange Board of India (SEBI) in January 2026 issued a no-objection certificate that allowed the exchange to restart its listing process.

NSE is in full pre-IPO swing, assembling an unusually large cast of advisors around the offering—around 20 investment banks, multiple global and domestic law firms, and an independent advisor in Rothschild—which suggests how tightly managed this listing will be.

But NSE is not just preparing for an IPO. It is working through the aftermath of a series of controversies that derailed its listing ambitions. Chief among them was the co-location scandal, where brokers were alleged to have gained unfair access to NSE’s trading systems and execute trades faster. The events took place from the early 2010s for a few years but regulatory scrutiny spanned close to a decade and raised serious questions about market integrity and internal controls.

An overlapping controversy known as the “dark fibre” case saw certain brokers allowed to use dedicated or preferential fibre routes to connect to NSE’s servers. Layered on top was the strange governance saga involving a former chief executive who in 2022 was penalised by SEBI for sharing confidential and sensitive information with an unidentified “yogi”, further denting confidence in the exchange’s board oversight.

Together, these episodes drew sustained regulatory scrutiny and effectively froze NSE’s listing ambitions for years. Still, while these issues are now technically settled, the chapter feels incomplete.

Enforcement has largely taken the form of fines, settlements and individual penalties, with limited public clarity into how decision-making structures have changed, or where accountability was apportioned within the institution. The focus appears to have been on closing cases rather than a broader institutional reckoning.

As a result, it is hard to tell whether the exchange has fundamentally changed, or simply checked the necessary boxes to move past scrutiny. There has been no single moment where responsibility was clearly pinned down. Instead, the system has adjusted, tightened its rules, and carried on.

A selective opening

The decision to float only around 4–5% of the company looks like a deliberate attempt to keep a tight grip—give existing shareholders some liquidity, but without really shifting who holds power, while also creating a sense of scarcity around the stock.

That approach has been made easier by changes in regulation. India recently revised its public float rules to enable companies such as NSE to list: from March 2026, mega-cap companies are being allowed to IPO with as little as 2.5% public float, eventually building up to 25%.

But the exchange will remain firmly under SEBI’s hand. Key appointments—from the CEO to public interest directors and other senior roles—require regulatory approval, embedding SEBI’s influence deep within the exchange’s governance.

Of its eight board members, five are Public Interest Directors, all of whom must be approved by SEBI. The chairperson and managing director are also subject to regulatory approval, meaning that at least six—and effectively seven, including the CEO—of the eight positions are directly vetted by the regulator.

Such oversight is not unusual for critical market infrastructure. The Bombay Stock Exchange (BSE) operates under the same framework. Yet it is a fully free-float company—so NSE’s more cautious approach looks at least partly shaped by its past.

Testing the grey market

The company which runs India’s largest stock exchange has spent the past decade being traded in an informal one.

NSE is one of the most actively traded names in India’s unlisted share market, where brokers, wealth managers and WhatsApp groups match buyers and sellers ahead of IPOs.

This IPO is therefore less about discovering a price than validating one already set. NSE has produced a widely accepted valuation in the unlisted market and has an investor base that rivals that of many public companies: it already has more than 100,000 shareholders.

Thus the IPO will also serve as India’s biggest test yet of the grey market’s price discovery. In the private market, NSE’s share price in early 2026 implied a valuation of around US$55-60 billion, putting it among India’s largest blue chips.

Recent IPOs have disappointed grey market investors, and any sharp divergence could invite scrutiny. SEBI has already flagged concerns over gaps between unlisted trading and IPO valuations, leaving this listing to validate—or undermine—the grey market and perhaps draw the regulator’s eye.
