Summary: NSE’s Draft Red Herring Prospectus presents the National Stock Exchange as a broad financial-infrastructure business rather than merely a traditional stock exchange. FY26 revenue from operations stood at approximately ₹16,601 crore, with ₹13,057 crore coming from transaction charges and equity options contributing approximately ₹9,998 crore, making options the dominant revenue driver. Data connectivity, listing services and index licensing remain smaller but faster-growing revenue streams. The DRHP also shows that revenue does not move simply with trading volume, as equity-options notional volume declined over FY24–FY26 while options revenue remained comparatively stable, supported partly by higher price realisation. NSE’s investor base and listed entities expanded substantially, but operating revenue did not rise at the same pace. NSE reported approximately ₹64,771 crore of treasury investments as of March 31, 2026, principally representing investments made from its own surplus funds and separate from member margins, settlement obligations and other restricted market-infrastructure balances. Although these investments demonstrate considerable financial strength, the entire amount cannot automatically be treated as freely distributable shareholder cash. Investment income provides another important earnings stream. NSE’s competitive position is supported by very high market shares, liquidity network effects, integrated clearing, risk management, technology, indices and data services. At the same time, technology expenses rose sharply as the exchange handled increasingly large order-message volumes. The DRHP therefore shifts the key investment question from whether NSE is simply a good IPO to how much additional Indian financial-market activity it can monetise and, once the offer price is announced, how much prospective growth will already be reflected in its valuation.
When we think of the National Stock Exchange of India (NSE), we usually think of one thing: trading.
But the NSE Draft Red Herring Prospectus (DRHP) tells a far more interesting story.
Behind every trade sits a massive financial infrastructure—clearing, settlement, margins, data, technology, indices and a sizeable treasury operation.
The numbers show that NSE is no longer just a traditional exchange taking a fee every time someone buys or sells a stock. It has built an entire ecosystem around market activity.
NSE Is Not Simply a “Stock Exchange” Business
NSE’s FY26 revenue from operations was approximately ₹16,601 crore. Of this, ₹13,057 crore came from transaction charges—almost 79% of operating revenue.
At first glance, the business looks substantially dependent on trading activity. But there is another layer.
NSE also earns from data connectivity, data feeds, listing services, index licensing and other services. Data connectivity revenue rose from ₹825 crore in FY24 to ₹1,129 crore in FY26, while listing services grew from ₹223 crore to ₹352 crore. Index licensing increased from ₹98 crore to ₹152 crore over the same period.
These segments are still small compared with transaction charges, but they are growing faster. That matters because they monetise NSE’s market infrastructure without requiring investors to place additional trades.
The Real Engine Sits in Options
Here is where the DRHP gets particularly interesting.
Of the ₹13,057 crore in FY26 transaction charges, approximately ₹9,998 crore came from equity options alone. Equity options therefore accounted for approximately 60% of NSE’s total operating revenue and nearly 77% of its transaction-charge revenue.
This changes how we should look at NSE. It is not enough to say that Indian markets are growing or that more investors are entering. NSE’s core economics are deeply tied to a particular activity: derivatives, especially equity options.
There is also an important detail. The notional trading volume of equity options declined over FY24–FY26. Nevertheless, options revenue remained comparatively stable—₹9,550 crore in FY24, ₹10,194 crore in FY25 and approximately ₹9,998 crore in FY26.
The DRHP notes that equity-options price realisation increased by 7.08% in FY26, partly offsetting the decline in volume. However, this should not necessarily be interpreted as a discretionary price increase because effective realisation can also change with product mix, premium turnover, contract specifications and the applicable charging structure.
The equation is therefore not simply:
- Revenue = Trading Volume
It is more accurately understood as:
- Revenue = Volume × Product Mix × Effective Pricing
Why the Distinction Matters
For an exchange, that distinction is crucial. Trading volumes may decline without causing an equivalent decline in revenue if product mix or effective realisation improves. Conversely, high growth in notional turnover may not necessarily produce proportionate revenue growth.
The performance of this segment must also be considered in the context of the regulatory framework for exchange-traded derivatives. Relevant requirements relating to margins, liquid assets and risk management are consolidated in the SEBI Master Circular on Matters Relating to Exchange-Traded Derivatives.
More Investors Do Not Automatically Mean More Revenue
NSE’s investor base has expanded rapidly. Unique registered investors grew from 91.75 million in FY24 to 129.09 million in FY26. Listed entities increased from 2,438 to 2,978 over the same period.
However, operating revenue did not grow at the same pace. It stood at ₹14,780 crore in FY24, increased to ₹17,141 crore in FY25 and declined to ₹16,601 crore in FY26.
This reveals a subtle truth: the next phase of NSE’s growth cannot rely solely on adding more registered investors. The larger opportunity lies in monetising existing market activity through increased participation, derivatives, data, indices, listings and other financial products.
The quality and intensity of participation matter far more than the headline investor count.
Decoding NSE’s Balance Sheet
This is one of the most important parts of the prospectus.
NSE reported treasury investments of approximately ₹64,771 crore as of March 31, 2026, up from ₹48,016 crore in FY24.
These treasury investments principally represent investments made from NSE’s own surplus funds. They should be distinguished from member margins, settlement obligations and other earmarked or restricted market-infrastructure balances.
The amount demonstrates NSE’s considerable financial strength and accumulated liquidity. However, it should not automatically be treated as a pool of cash that can be distributed entirely to shareholders.
NSE must continue to satisfy regulatory capital, liquidity, operational, technology, risk-management and statutory-reserve requirements. Potential contingent liabilities, litigation exposure, settlement-guarantee obligations and future capital requirements must also be considered before estimating surplus cash available for distribution.
Separately, an exchange and its clearing infrastructure manage substantial member margins, collateral and settlement-related funds that do not economically belong to shareholders. Settlement obligations and member margin money were approximately ₹30,147 crore as of March 2026.
These third-party or operational balances must be analysed separately from NSE’s treasury investments. The ₹30,147 crore of settlement obligations and member margin money should not be used to characterise NSE’s ₹64,771 crore of treasury investments as restricted or belonging to market participants.
The regulatory requirements applicable to stock exchanges and clearing corporations are consolidated in the SEBI Master Circular for Stock Exchanges and Clearing Corporations.
Earning From the Money Behind the Trades
There is another source source of earnings that can be easy to overlook.
NSE earns investment returns on its treasury investments and certain operational funds. Depending upon the nature of the underlying funds and the applicable accounting classification, investment-related income may be presented either within operating revenue or under other income.
In FY26, investment income included under “other income” was approximately ₹1,929 crore. Additionally, investment-related income classified within operating revenue was approximately ₹842 crore.
These income streams must be interpreted carefully. Income generated from NSE’s own treasury investments should be distinguished from income associated with margins, collateral or other operational funds.
This gives the exchange two broad economic engines:
1. Income generated from the activity of the market.
2. Income generated from investments and funds supporting or accumulated through the business.
This helps explain the exchange’s high margins, but it also means that looking only at transaction revenue does not capture the complete economics reflected in its income statement and balance sheet.
A Strong Moat With a High Price Tag
NSE’s market position is dominant. In FY26, its market share was approximately 93% in the cash market, 99.79% in equity futures and 74.71% in equity options, based on premium turnover.
However, the real moat is not merely its high market share—it is the network effect.
- More liquidity attracts more traders.
- More traders create deeper liquidity.
- Deeper liquidity attracts more brokers and institutions.
Once an exchange becomes the principal liquidity hub, displacing it becomes extremely difficult. NSE reinforces this network through integrated clearing, risk management, technology, indices and data services.
The regulatory framework governing the recognition, ownership and governance of stock exchanges and clearing corporations is set out in the Securities Contracts (Regulation) (Stock Exchanges and Clearing Corporations) Regulations, 2018.
Yet this moat comes at a cost. Technology expenses increased from ₹786 crore in FY24 to ₹1,315 crore in FY26, representing a compound annual growth rate of approximately 29.3%.
In March 2026, NSE handled a peak of 21.89 billion order messages in a single day.
Calling NSE “asset-light” is therefore accurate only in a limited sense. It does not require factories or large conventional manufacturing facilities, but it requires continuous and substantial investment in fast, reliable, secure and resilient technology systems.
Key Takeaways From the DRHP
At its core, NSE is a financial-infrastructure powerhouse whose most visible product happens to be a stock exchange.
- Revenue concentration: Transaction revenue relies heavily on derivatives, particularly equity options.
- Competitive moat: NSE’s position is supported by liquidity, network effects, scalable technology and integrated clearing and risk-management systems.
- Growing ancillary revenue: Data connectivity, listing services and index licensing remain relatively small but are growing faster than transaction revenue.
- Complex balance sheet: NSE’s own treasury investments must be distinguished from member margins, settlement obligations and other restricted or third-party balances.
- Investment income: Returns on treasury and operational funds form an important component of NSE’s overall earnings.
- Regulatory exposure: NSE’s revenue, especially from equity options, remains sensitive to changes in derivatives regulation, contract design, margins and trading activity.
- Technology requirements: The business requires substantial and continuing expenditure on capacity, cybersecurity, resilience and trading infrastructure.
The DRHP ultimately shifts the focus away from a simple question such as “Is NSE a good IPO?” to a more critical one:
How much additional Indian financial-market activity can NSE successfully monetise—and, once the offer price is announced, how much of that prospective growth will already be reflected in its IPO valuation?
