National Stock Exchange of India Limited (NSE) will open its mainboard IPO on 17 September 2026 and close on 21 September 2026, with listing scheduled for 24 September 2026. The price band is ₹1,700 to ₹1,785 per share and the lot size is 8 shares. The total issue size is ₹26,579.64 crore and the issue is entirely an offer for sale (OFS), with no fresh issue component.

What NSE does and how the group earns revenue

NSE is a vertically integrated, multi-asset stock exchange group in India that operates an electronic marketplace for trading and listing across equities, equity derivatives, currency derivatives, commodities, mutual funds and fixed income. It is supported by in-house trading technology and post-trade infrastructure through clearing and settlement subsidiaries, including NSE Clearing Limited.

Alongside the core exchange and clearing stack, NSE also operates complementary businesses such as NSE Indices and NSE Data & Analytics. The revenue model described in the RHP is driven largely by transaction charges and also includes other income streams linked to market infrastructure, such as listing fees, colocation and connectivity, data feeds and terminals, index licensing, clearing services and investment income.

NSE also performs first-level market regulator functions, including surveillance, compliance and investor protection, alongside its commercial operations. This dual role is a defining feature of how the institution functions in India’s market structure.

Milestones and scale indicators cited in the offer documents

NSE was incorporated in 1992 and was recognised as a stock exchange by the Ministry of Finance, Government of India in 1993. It commenced screen-based trading in 1994 and established the Investor Protection Fund Trust and introduced the NEAT screen-based electronic trading system in 1995. The Nifty 50 index was launched in 1996, and the exchange subsequently expanded product coverage over time across index and single-stock derivatives, ETFs, currency derivatives and commodity derivatives.

The offer documents also highlight the platform’s progression into newer channels and market infrastructure initiatives, including internet trading (commenced in 2000), and the SME platform EMERGE (launched in 2012). NSE’s international initiative in GIFT City is referenced through NSE International Exchange (NSEIX), and the RHP also cites regulatory approval and inauguration related to the NSE IX–SGX Connect.

Recent operational and scale markers in the stated milestones include expansion in the registered investor base and high throughput on peak trading days. The milestones section notes that the unique registered investor base crossed over 110 million in January 2025 and crossed about 130 million in 2026. It also cites peak daily processing levels, including execution of 201.00 million trades on 24 March 2026, and a single-day peak of 293.85 million trades on 4 June 2024.

Product and market development initiatives mentioned for 2024–2026 include a beta version of T+0 settlement in the equity segment, electricity futures, electronic gold receipts, and Brent crude oil (Platts) futures. The milestones also note the incorporation of National Coal Exchange of India Limited on 19 June 2026 after SEBI approval, and the launch of a closing auction session in the equity cash segment.

IPO structure, objects of the offer, and who receives proceeds

At this snapshot, NSE’s IPO is structured entirely as an OFS of ₹26,579.64 crore, with no fresh issue. In an OFS, shares are sold by existing shareholders; proceeds from the OFS go to the selling shareholders and not to NSE. With no fresh issue component, NSE is not raising primary capital through this IPO.

The stated objects of the offer include carrying out the OFS of up to 126,436,650 equity shares of face value ₹1 each by certain selling shareholders, and achieving the benefits of listing the equity shares on BSE.

The IPO is a mainboard issue with a lot size of 8 shares. Category-wise reservations disclosed at this snapshot indicate 50% for Qualified Institutional Buyers (QIBs), 15% for Non-Institutional Investors (NIIs) and 35% for Retail Individual Investors (RIIs). The offer also indicates that anchor allocation is a portion of the QIB category, with up to 60% of the QIB portion available for anchor investors and a 33.33% reservation within the anchor book for domestic mutual funds. The snapshot also carries employee and shareholder reservation amounts of ₹70 crore and ₹71 crore, respectively.

Financial trajectory across FY2024 to FY2026

NSE’s reported financials show movement across FY2024, FY2025 and FY2026 in total revenue, profit after tax (PAT) and total assets. The financial profile should be read in the context of exchange economics described in the RHP, where revenues are driven by transaction-linked activity as well as non-transaction streams such as listing, connectivity, data/analytics, index licensing, clearing services and investment income.

In narrative terms, the table shows that FY2026 total revenue and PAT are below FY2024 levels, while total assets increased in FY2025 compared with FY2024 and are reported at the same level in FY2026 as in FY2025. The PAT margin in the table remains above 60% across the three financial years presented.

Valuation and KPI context disclosed for the IPO

The RHP discloses key performance indicators (KPIs) and valuation references at the IPO price band. These include earnings per share (EPS), return on equity (ROE), return on capital employed (ROCE), return on net worth (RoNW), EBITDA margin (as a percentage) and reported PAT margin.

At the disclosed snapshot values, EPS is ₹41.62, ROE is 32.98%, ROCE is 42.80% and RoNW is 33.21%. EBITDA margin is reported at 77.59% and PAT margin is reported at 50.98%. Valuation references in the snapshot include a pre-IPO price-to-earnings (P/E) multiple of 42.89 times and a price-to-book multiple of 13.76 times. Debt-to-equity is reported as 0.

For a market-infrastructure business such as an exchange group, these KPIs are typically considered alongside the revenue mix (transaction-linked versus non-transaction), the contribution from data/indices and connectivity, and how regulatory settings affect product design and trading activity.

Key risks highlighted and monitoring points to track

The risk themes highlighted in the supplied context focus on the sensitivity of exchange revenues to trading activity and regulation, operational resilience expectations, and concentration factors.

First, the context flags that a significant portion of revenue depends on trading volumes, especially options. It also cites that regulatory recalibrations such as expiry-day rules, limits on weekly expiries, higher securities transaction tax (STT), and tighter margin and position norms may reduce turnover, particularly in derivatives.

Second, the context highlights revenue concentration, noting that a large share of revenue comes from a small set of trading members. A loss of a few active members could reduce volumes and affect the economics of transaction-linked income.

Third, technology and security risks are central for an exchange. The context notes that technology failures or cyberattacks could disrupt trading, damage trust and invite regulatory action. It also highlights that systemically critical infrastructure requires continuous technology and security investment, and that faster settlement cycles such as T+1 and initiatives such as T+0 can create capacity, interoperability and operational strains if infrastructure lags volumes.

Fourth, the context references regulatory inspections, past notices and settlement payments as an ongoing compliance and governance risk, with the potential for penalties, restrictions and reputational impact.

Monitoring points, based on the business model and stated risks, include watching for changes in the revenue mix between transaction charges and non-transaction streams such as data, indices, connectivity and listing; tracking regulatory changes that affect derivatives market structure and participation; tracking platform stability and cybersecurity posture given the systemically important role of the exchange; and tracking concentration indicators across active trading members and segments.
