After years of regulatory delays and anticipation, the National Stock Exchange of India is finally preparing to enter the public markets, and the numbers attached to its IPO underline just how important the exchange has become to India’s financial system.

NSE has fixed a price band of ₹1,700 to ₹1,785 per share for its much-awaited initial public offering. At the upper end of the band, the exchange is being valued at approximately ₹4.42 lakh crore, or $46.3 billion. The IPO is scheduled to open for subscription on September 17 and close on September 21, with the listing expected around September 24, according to current market reports.

The valuation places NSE in a different league from its domestic rival, the Bombay Stock Exchange.

BSE’s market capitalisation stood at around ₹1.34 lakh crore as of September 9, according to market data. At the upper end of NSE’s IPO price band, the National Stock Exchange would therefore command a valuation of roughly 3.3 times BSE’s market value.

That valuation gap is one of the most closely watched aspects of the NSE IPO.

Why NSE commands such a premium

The difference is not simply about the number of companies listed on each exchange. NSE has built a dominant position in actual trading activity, particularly in equity derivatives.

The exchange operates the benchmark Nifty 50 index and has become India's principal venue for equity trading. It is also the world's most active derivatives exchange by the number of contracts traded.

The financial performance further explains why investors are willing to attach such a large valuation to NSE.

For the financial year ended March 2026, NSE reported revenue from operations of approximately ₹16,601 crore, more than three times BSE's ₹4,834 crore, according to financial comparisons based on the exchanges' disclosures.

NSE's latest quarterly numbers have also remained strong. In the June 2026 quarter, the exchange reported net profit of around ₹3,120 crore, compared with ₹2,923 crore a year earlier. Revenue from operations rose to approximately ₹4,560 crore from ₹4,032 crore.

A major milestone after nearly a decade

The IPO has an unusually long backstory.

NSE first filed its IPO documents in 2016, but regulatory and legal issues surrounding the exchange delayed its public-market ambitions for years.

A major hurdle was removed this month after the Supreme Court dismissed a long-running case involving allegations relating to preferential access to NSE's trading systems. The development followed a settlement process involving the market regulator.

SEBI subsequently cleared NSE's IPO process, allowing the exchange to move towards what is expected to become one of India's largest stock-market listings.

The offering is particularly significant because it is an offer for sale, meaning existing shareholders are selling their holdings rather than NSE issuing new shares to raise fresh capital. The exchange itself will therefore not receive the IPO proceeds.

SBI and other major investors among sellers

A number of prominent institutional investors are participating in the offer.

The selling shareholders include State Bank of India, SBI Capital Markets, Bank of Baroda, Canada Pension Plan Investment Board and other institutional investors. LIC, one of NSE's largest shareholders, is not participating in the offer and is expected to retain its holding.

The final IPO size has also been reduced from earlier expectations. NSE is now offering around 126.4 million shares, with the reduction attributed partly to shareholders cutting the number of shares they intend to sell at the revised valuation.

NSE versus BSE: the valuation battle

The IPO is also creating an interesting valuation comparison between India's two major exchanges.

BSE has delivered an extraordinary stock-market performance since its listing in 2017, with its market capitalisation rising sharply as trading activity, particularly in derivatives, expanded. Its market cap is currently around ₹1.34 lakh crore.

But NSE's expected valuation of ₹4.42 lakh crore would put it more than three times higher.

That does not necessarily mean NSE will automatically outperform BSE as an investment after listing. Public-market valuations can change rapidly once shares begin trading, and the final market value will ultimately depend on investor demand, earnings growth and expectations for India's capital markets.

For NSE, however, the IPO provides something that has been missing for years: a transparent public-market valuation.

Why the IPO matters for India's financial markets

The NSE listing is bigger than a conventional IPO story.

The exchange is at the centre of India's capital-market infrastructure. Its trading systems, indices and derivatives markets are closely connected to the country's investment ecosystem.

The exchange also had more than 3,000 listed companies on its platform as of June 2026, with the combined market value of those companies approaching $5 trillion. (

A successful NSE listing could therefore become another marker of the growing scale of India's financial markets.

It also comes at a time when India's IPO market is regaining momentum, with several large companies preparing to tap public investors.

Global ranking in focus

At an expected valuation of about $46 billion, NSE would rank among the world's most valuable publicly traded exchange operators. Depending on the valuation date and the exchange-ranking methodology used, estimates place it around the upper tier of global exchanges.

Earlier unlisted-market valuations had put NSE closer to $55 billion, but the final IPO price band has brought the proposed valuation down to around $46 billion.

That adjustment is important. Investors are no longer valuing NSE purely on its private-market expectations; the IPO will provide the first major public test of what the market is actually willing to pay.

The bigger question after listing

The NSE IPO may dominate India's primary market in the coming days, but the more important story could begin after the listing.

Investors will be watching whether NSE can maintain its commanding position in derivatives and cash-market trading while navigating regulatory changes, taxation and evolving market behaviour.

The exchange has already demonstrated its importance to India's financial ecosystem. Now, the public markets will decide how much that dominance is worth.

At a valuation of up to ₹4.42 lakh crore, NSE is entering the public markets not merely as another IPO candidate, but as one of India's most valuable financial institutions and with a valuation more than three times that of its historic domestic rival, BSE.
