India’s biggest stock exchange is finally going public, roughly a decade after it first tried. The Securities and Exchange Board of India (SEBI) granted clearance on September 4 for the National Stock Exchange of India (NSE) to proceed with an initial public offering projected to raise around ₹30,000 crore, or approximately $3.6 billion.
That would make it the largest IPO in India’s recent history. The exchange carries an unlisted valuation of roughly $55 billion, which would slot it comfortably among the country’s top ten companies by market capitalization.
A decade in the making
NSE first filed its draft red herring prospectus back in December 2016. The long delay wasn’t bureaucratic foot-dragging for its own sake. SEBI had been investigating the exchange over a co-location controversy, where certain traders allegedly received preferential access to NSE’s servers through dark fibre connections. Governance lapses compounded the problem. The exchange eventually settled with the regulator, paying roughly ₹14.91 billion (about $155 million) to resolve the matter.
With those issues finally in the rearview mirror, the regulatory dominoes fell quickly in 2026. SEBI issued a no-objection certificate in January. NSE’s board approved the offer-for-sale structure in February. The exchange filed a fresh DRHP on June 17. And now, the final clearance.
NSE Chairperson Srinivas Injeti called the approval a monumental achievement in the exchange’s evolution.
How the IPO is structured
The offering is structured as a 100% offer-for-sale of approximately 14.89 crore shares, representing about 6% of NSE’s paid-up capital. That means existing shareholders are cashing out a portion of their holdings. NSE itself won’t raise any fresh capital from the listing.
Among the key sellers is State Bank of India (SBI) Group, which is expected to offload up to roughly 2.48 crore shares. Other institutional shareholders will also participate in the sale.
Because of regulatory rules preventing an exchange from listing on its own platform, NSE will debut on the Bombay Stock Exchange (BSE). BSE, for its part, offers a compelling data point for what exchange listings can deliver in India. Since its own IPO in 2017, BSE’s shares have risen 28-fold.
The IPO could launch as early as mid-September 2026, which would position it ahead of another highly anticipated debut: Jio Platforms.
Why this matters beyond India
For international investors, the listing creates a direct way to bet on the growth trajectory of Indian capital markets themselves, rather than picking individual stocks within them.
Domestic investors have been waiting years for this opportunity. NSE shares have traded on India’s unlisted market at steadily climbing premiums, reflecting pent-up demand from institutions and high-net-worth individuals who couldn’t access the stock through normal channels.
