India's largest stock exchange, the National Stock Exchange (NSE), is moving closer to its long-awaited public listing via the IPO route. In a fresh research note, global brokerage Jefferies has outlined why it believes the exchange is uniquely positioned among global peers, citing its dominant market position, diversified revenue streams, robust profitability, strong cash generation and improving regulatory outlook.Here are the five key reasons highlighted by the brokerage:1) India's options boom has transformed NSE's businessJefferies says India has become an options-driven market, with the equity options segment expanding at a 56% compound annual growth rate (CAGR) between FY20 and FY26, significantly outpacing the 19% CAGR seen in the cash market.The brokerage estimates derivatives now contribute nearly 70% of Indian exchanges' operating revenues. While options trading volumes are among the highest globally, India's option premiums remain just about one-fifth of those in the US, indicating further room for market development.Also Read | NSE eyes September launch for $3 billion IPO; marketing likely to begin next week2) Unmatched market leadership across segmentsAccording to Jefferies, NSE commands over 90% market share across most trading categories, including equities, stock futures, equity futures and currency derivatives.The exchange also enjoys an 88% share in cash market clearing through its clearing corporation (NCL). Beyond trading, technology and data services account for nearly 13% of its FY26 revenues, providing an additional growth engine.The brokerage believes this diversified business model distinguishes NSE from domestic peers while making it comparable to leading global exchanges.Also Read | IPO-bound NSE set to be the change in exchange game3) NSE among the world's most profitable exchangesDespite regulatory provisions weighing on reported earnings over the past two years, Jefferies notes that NSE continues to rank among the most profitable exchanges globally.The brokerage estimates that excluding one-time regulatory expenses related to Sebi settlements, NSE's operating EBITDA margin has remained stable at around 76-77% between FY24 and FY26.This profitability has been supported by the exchange's dominant clearing business, premium derivatives franchise and efficient cost structure.4) Strong balance sheet supports generous shareholder payoutsJefferies highlights NSE's robust financial position, noting that the exchange held investment assets worth around ₹28,800 crore across government securities and mutual funds during FY26.Combined with limited capital expenditure requirements, which is estimated at just 3-3.5% of revenues, and strong operating cash flows have enabled the company to return a substantial portion of earnings to shareholders.According to the brokerage, NSE distributed about 74% of earnings as dividends in FY25 and approximately 85% in FY26.5) Regulatory overhang appears manageableWhile acknowledging that regulatory actions and litigation have weighed on investor sentiment, Jefferies believes much of the uncertainty is already being addressed.NSE has made provisions for settlements with the Securities and Exchange Board of India (Sebi), including matters relating to colocation and dark fibre cases. The brokerage expects these one-off expenses to have a limited impact on the exchange's long-term earnings profile.At the same time, the report notes that regulatory changes, including restrictions on weekly index options and higher minimum contribution requirements for the derivatives settlement guarantee fund, affected the exchange during FY25 and FY26.Jefferies estimates NSE generated operating revenue of Rs 16,601 crore in FY26, while reported operating EBITDA stood at Rs 11,098 crore. Reported EBITDA margin was 66.8%, though the brokerage estimates normalised EBITDA margin at around 76.2% after adjusting for exceptional regulatory costs.The brokerage believes the proposed NSE listing will provide investors access to one of India's strongest financial infrastructure businesses. The brokerage says the exchange combines market leadership, diversified revenue streams, high profitability, strong cash generation and scalable technology offerings—traits that compare favourably with leading global exchanges.As regulatory issues move closer to resolution, Jefferies expects the IPO to draw significant investor interest given NSE's dominant position in India's rapidly expanding capital markets.(Disclaimer: Recommendations, suggestions, views and opinions given by the experts are their own.
