NSE IPO Enters Execution Phase: OFS Process Underway For ₹20,000+ Cr

National Stock Exchange Formally Launches IPO Process Through OFS Route

The National Stock Exchange of India has officially entered the execution phase of its highly anticipated initial public offering by issuing formal offer for sale letters to existing shareholders. This marks a concrete step forward in what is expected to become one of the largest public offerings in Indian market history.

India's premier stock exchange recently contacted its shareholder base to gauge their interest and obtain consent for participating in the proposed public issue. The entire offering will be structured as an offer for sale, meaning existing shareholders will divest their holdings to new public investors rather than the company raising fresh capital.

According to information available about the planned offering, the issue size could exceed ₹20,000 crore. This figure places the NSE IPO among the largest public offerings ever conducted on Indian bourses, comparable to landmark listings such as Life Insurance Corporation and Hyundai Motor India.

The exchange has set clear eligibility criteria for shareholders who wish to participate in the OFS component. Only those who held NSE shares on or before June 15, 2025, will be permitted to tender their holdings in the public issue. Shareholders who acquired shares after this cutoff date will not qualify for participation.

This eligibility date was strategically chosen to fall at least one year before the expected filing of the draft red herring prospectus with regulators. The one-year holding requirement ensures that long-term shareholders have the opportunity to monetize their investments through the public offering.

Understanding the Offer for Sale Mechanism

An offer for sale differs fundamentally from a fresh issue of shares in terms of how capital flows and who ultimately benefits from the transaction. In a fresh issue, the company itself issues new shares and receives the proceeds, which then become available for business expansion, debt reduction, or other corporate purposes.

In contrast, an offer for sale involves existing shareholders selling a portion of their holdings to public market investors. The proceeds from an OFS go directly to the selling shareholders rather than to the company's balance sheet. The company neither raises capital nor dilutes its existing paid-up share capital through this route.

For NSE's IPO, the decision to pursue a pure OFS structure means that the exchange's operational and financial resources will remain unchanged post-listing. The company will continue running its business with the same capital base it currently maintains as an unlisted entity.

The OFS route serves multiple purposes for different stakeholders. For existing institutional investors who backed NSE during its private phase, the offering provides an exit opportunity to monetize years of patient capital. For the broader market, it creates access to ownership in an institution that has been central to India's capital market ecosystem for over three decades.

For NSE itself, listing through OFS allows the company to become publicly traded and establish a market-determined valuation without altering its capital structure or taking on obligations associated with fresh fundraising. This approach aligns with the exchange's position as a mature, profitable entity that does not require additional capital for operations.

Shareholder Consent and Participation Process

The NSE has initiated a structured process to obtain consent from eligible shareholders regarding their willingness to participate in the OFS. The exchange issued formal letters to shareholders outlining the terms, conditions, and procedures for tendering shares in the proposed public offering.

Shareholders who wish to participate must submit an expression of interest by April 27, 2026, at 5:00 PM. This deadline provides existing shareholders with adequate time to evaluate the opportunity, consult advisors if necessary, and make informed decisions about partial or complete divestment of their holdings.

It is important to note that submitting an expression of interest does not constitute a binding commitment. Rather, it indicates a shareholder's preliminary interest in potentially selling shares through the IPO. The actual allocation and sale will depend on various factors including the final issue size, pricing, and regulatory approvals.

Shareholders participating in the OFS must ensure their shares meet specific conditions. The shares must be fully paid-up with no outstanding payment obligations. They must have been held continuously since June 15, 2025, without any gap in ownership. Additionally, the shares should not be subject to any court or tribunal order, nor should they carry any charge, lien, pledge, encumbrance, or transfer restriction.

The exchange has also specified that selling shareholders will be restricted from participating as investors in the IPO. This prevents a situation where shareholders could simultaneously sell shares through OFS and apply for allotment in the public portion, which would create conflicts of interest and complicate the book-building process.

All shares offered through the pre-IPO OFS will be subject to a lock-in period of six months from the date of allotment in the public offering. This lock-in requirement ensures that selling shareholders cannot immediately exit their remaining holdings post-listing, providing stability to the stock in its initial trading period.

NSE's Unusual Shareholder Structure

One of the most distinctive aspects of the NSE IPO is the company's extraordinarily broad shareholder base despite never having conducted a public issue. As of early 2026, NSE has approximately 1.91 lakh shareholders, making it the largest unlisted company in India by shareholder count.

This wide ownership distribution has evolved organically over the years through secondary market transactions in unlisted shares. Since NSE never raised public capital through an IPO, the only way individuals and institutions could acquire stakes was by purchasing shares from existing holders in the unlisted market.

The shareholder count has expanded dramatically in recent years. In December 2023, NSE had around 5,000 shareholders. This number grew to approximately 20,500 by December 2024 and further swelled to about 1.84 lakh by December 2025 before reaching its current level of 1.91 lakh.

This massive expansion in shareholder numbers reflects growing investor interest in acquiring NSE stakes ahead of the anticipated IPO. The unlisted share market for NSE has been active for years, with shares changing hands at privately negotiated prices that reflect market participants' views on the exchange's value.

Such a broad shareholder base creates both opportunities and challenges for the IPO process. On one hand, it demonstrates widespread confidence in NSE's business model and long-term prospects. On the other hand, coordinating with nearly 2 lakh shareholders to obtain participation consent, collect necessary documentation, and manage the logistics of share tendering represents a significant operational undertaking.

The exchange must legally notify each eligible shareholder about the OFS opportunity and obtain their agreement to participate. Processing expressions of interest from potentially tens of thousands of shareholders requires robust systems and dedicated resources. This logistical complexity distinguishes the NSE IPO from typical large offerings that involve a handful of institutional selling shareholders.

Estimated Issue Size and Valuation

Market estimates suggest that existing shareholders may offload approximately 4.5 to 5 percent of NSE's equity through the public offering. The final percentage will depend on factors including regulatory requirements for minimum public shareholding, demand during book-building, and strategic considerations about maintaining adequate float for trading liquidity.

Based on prevailing unlisted market prices for NSE shares, which have been trading in the range of ₹1,900 to ₹2,150 per share during recent months, analysts estimate the total market capitalization of the exchange at approximately ₹4.70 to ₹5 lakh crore. Some investment banking sources have suggested that NSE may seek valuations in the ₹6 to ₹7 lakh crore range during the IPO, representing a premium to current unlisted trading levels.

If the offering involves a 4.5 to 5 percent dilution at these valuations, the total issue size would range from approximately ₹21,000 crore to ₹25,000 crore. This would position the NSE IPO among the largest ever in Indian capital markets, comparable in scale to the Life Insurance Corporation offering of ₹20,557 crore in 2022 and the Hyundai Motor India IPO of ₹27,859 crore in 2024.

The actual pricing will be determined through a book-building process where institutional investors submit bids within a specified price band. The final issue price represents a balance between maximizing proceeds for selling shareholders and ensuring sufficient demand to support the stock post-listing.

At the estimated market capitalization levels, NSE would rank among India's top 15 most valuable companies upon listing. The current threshold for the top 15 companies ranges from approximately ₹3.77 lakh crore to ₹18.87 lakh crore. NSE's entry into this elite group would be particularly notable given that it would be the first stock exchange globally to achieve such a high market valuation.

Regulatory Clearances and Timeline

The NSE IPO process has progressed through several regulatory milestones over the past few months. In February 2026, the exchange's board of directors approved the plan to pursue a public listing exclusively through the offer for sale route. This board approval formalized the company's intent and authorized management to proceed with necessary preparations.

The Securities and Exchange Board of India granted a no-objection certificate to NSE for proceeding with its IPO plans. This NOC represented a crucial regulatory clearance that had been pending for several years due to unresolved compliance matters related to the co-location case and other governance issues.

NSE filed a settlement application with SEBI in June 2025 to resolve outstanding regulatory matters. The settlement involved NSE agreeing to pay approximately ₹1,400 crore to close investigations related to co-location practices and other alleged lapses. The exchange made a provision of ₹1,297 crore in its November 2025 financial disclosures to account for this settlement obligation.

With regulatory clearances now in place, NSE is targeting to file its draft red herring prospectus by the end of March 2026 or early April 2026. The timing of the DRHP filing depends on which quarter's financial statements will be included in the prospectus. Regulations allow companies to file offer documents with financial statements that are not more than six months old.

If NSE uses its September 2025 quarter audited financials, the filing could occur by March 31, 2026. Alternatively, if the company opts to include December 2025 quarter results, the filing timeline may extend into early April. The choice depends on operational readiness and strategic considerations about presenting the most current financial picture to potential investors.

Following DRHP filing, SEBI typically takes several weeks to review the documents and raise queries or seek clarifications. Companies respond through amendments or corrigendum filings. Once SEBI is satisfied with disclosures and compliance, it issues formal observations allowing the company to proceed with filing the final red herring prospectus.

Based on the current timeline, market participants expect the NSE IPO to potentially open for public subscription sometime in the second half of 2026, subject to market conditions and regulatory processing timelines.

Merchant Banker Selection and IPO Structure

NSE has appointed a large syndicate of merchant bankers to manage its public offering. According to reports, the exchange has selected 20 book running lead managers for the transaction. This represents one of the largest banker syndicates ever assembled for an Indian IPO.

The decision to appoint multiple lead managers reflects the exceptional size and complexity of the offering. With an estimated issue size exceeding ₹20,000 crore and a shareholder base of nearly 2 lakh individuals and institutions, the transaction requires substantial distribution capabilities and coordination.

The merchant bankers will collectively handle various aspects of the IPO process. This includes preparing the draft red herring prospectus, conducting due diligence on the company's business and financials, determining an appropriate valuation range, structuring the offer to optimize demand, conducting roadshows and investor meetings, managing the book-building process, and coordinating allocation among different investor categories.

Rothschild & Co has been appointed as an independent advisor to the transaction. The independent advisor provides guidance on valuation, market positioning, and strategic decision-making throughout the IPO process. This additional layer of advisory support is common in very large or complex transactions.

The final merchant banker appointments and their respective roles were expected to be finalized by mid-March 2026. Each lead manager typically underwrites a portion of the issue and is responsible for procuring bids from institutional investors within their network.

NSE's Market Position and Business Performance

Understanding NSE's dominant position in India's capital markets ecosystem provides context for the extraordinary investor interest in its IPO. The exchange operates the country's largest equity trading platform and has maintained market leadership across multiple segments for over two decades.

In the cash equity segment, NSE holds a market share of approximately 93 percent as of early 2026. This near-monopoly position reflects the exchange's technological superiority, trading infrastructure, and the network effects that come from being the primary venue where institutional and retail investors meet for price discovery.

In the derivatives segment, NSE commands a 57 percent market share in terms of notional turnover as of early 2026, up from 52 percent in January. The exchange is the world's largest derivatives trading venue by number of contracts traded, with equity index and stock futures and options forming the backbone of this business.

Globally, NSE ranked as the largest derivatives exchange and the third largest cash equity market by number of trades for calendar year 2023. The exchange facilitates trading worth trillions of rupees daily across equity, equity derivatives, debt, currency derivatives, and commodity derivatives segments.

As of early 2026, NSE oversees securities with a combined market capitalization exceeding ₹460 lakh crore. The exchange provides trading, clearing, settlement, indexing, and market data services across asset classes. India's capital markets ecosystem is fundamentally dependent on NSE's infrastructure and operational reliability.

The exchange reported a consolidated net profit of ₹2,924 crore for the quarter ended June 2025, representing a 14 percent increase year-on-year and 10 percent growth quarter-on-quarter. Total income for the quarter stood at ₹4,798 crore, up 9 percent sequentially.

For the nine months ended December 2025, NSE reported profit after tax of ₹7,431 crore, down 22 percent from ₹9,538 crore in the same period the previous year. Total income declined 10 percent to ₹13,354 crore from ₹14,780 crore. This decline was attributed to higher Securities Transaction Tax impacting derivatives volumes and changes in pricing structures.

Despite the year-on-year decline in certain financial metrics, NSE remains a highly profitable enterprise with strong cash generation capabilities. The company's business model benefits from operating leverage, where incremental volumes translate directly into higher margins since fixed infrastructure costs are already covered.

Historical Context: A Decade-Long Journey to Listing

NSE's path to public markets has been far from straightforward. The exchange first attempted to list in 2016, filing preliminary papers with regulators. However, that listing effort was halted when SEBI launched investigations into alleged irregularities related to co-location facilities and preferential access provided to certain high-frequency trading firms.

The co-location controversy centered on whether certain broker-dealers received unfair advantages through their proximity to the exchange's trading servers. Investigations revealed that some firms had exploited technological loopholes to gain milliseconds of advantage over other market participants, potentially violating market fairness principles.

For nearly a decade, NSE focused on resolving these regulatory issues, strengthening governance structures, and satisfying SEBI's conditions for allowing the exchange to proceed with its listing. During this period, the exchange avoided engaging with regulators on the IPO topic, instead prioritizing the resolution of compliance matters.

The co-location case saw multiple layers of investigation involving SEBI, the Central Bureau of Investigation, and other enforcement agencies. Former senior executives of the exchange faced questioning and regulatory action. The matter extended to criminal investigations and became a significant overhang on NSE's listing aspirations.

The narrative shifted meaningfully in 2025 when NSE filed its settlement application with SEBI, agreeing to pay a substantial penalty to close the co-location matter. In early 2026, regulatory clearances began falling into place, including SEBI's no-objection certificate and the CBI's acceptance of closure reports in certain aspects of the case.

The Delhi High Court also dismissed a petition challenging SEBI's no-objection for the NSE IPO, calling the plea an attempt to obstruct the listing process. This legal clearance removed another potential hurdle that could have delayed the offering.

With these matters now largely resolved, NSE has moved from speculation about listing to concrete execution of the IPO process. The decade-long journey underscores the importance of corporate governance and regulatory compliance, particularly for institutions that occupy systemically important positions in the financial ecosystem.

Investment Considerations and Market Implications

The NSE IPO presents unique considerations for potential investors. Unlike typical initial public offerings where companies seek capital for expansion or existing investors seek complete exit, this transaction offers access to ownership in a mature, highly profitable financial market infrastructure company.

NSE operates what is effectively a monopoly in certain market segments, particularly cash equities. The network effects inherent in exchange businesses create natural barriers to competition. Liquidity attracts more participants, which in turn deepens liquidity, creating a self-reinforcing dynamic that is difficult for competitors to replicate.

The business model generates predictable revenue streams tied to market activity. Transaction fees from trading, listing fees from companies, data licensing revenues, and technology service charges create diversified income sources. While trading volumes can fluctuate with market sentiment, NSE benefits from secular growth in Indian capital markets participation.

However, several risk factors warrant consideration. Regulatory changes could materially impact the business. Adjustments to transaction tax structures, changes in trading rules, or mandates around competitive neutrality could affect volumes and profitability. The exchange operates in a highly regulated environment where policy decisions significantly influence outcomes.

Competition from other platforms, including BSE and newer technology-driven trading venues, could pressure market share and pricing power. While NSE's dominant position provides significant advantages, maintaining that leadership requires continuous technology investment and service quality improvements.

The company's financial performance shows some volatility related to policy changes. The decline in profit during recent quarters was attributed to higher Securities Transaction Tax and its impact on derivatives trading behavior. Similar policy interventions in the future could create earnings uncertainty.

Valuation will be a critical determinant of returns. At the rumored valuations of ₹6 to ₹7 lakh crore, NSE would trade at substantial premiums to global exchange peers on metrics such as price-to-earnings ratios. Investors must assess whether such premium valuations are justified by growth prospects, profitability levels, and competitive positioning.

The large issue size and broad retail participation expected in the offering could create supply-demand dynamics that influence listing performance. While NSE's brand recognition and business fundamentals support strong demand, the sheer scale of shares being sold requires substantial capital deployment by investors.

Broader Market Significance

Beyond its financial dimensions, the NSE IPO carries symbolic importance for India's capital markets. The exchange has been the primary venue enabling thousands of companies to raise capital and millions of investors to participate in wealth creation. Its own transition to becoming a publicly traded company represents a coming full circle.

The listing will establish a market-determined valuation for exchange infrastructure as an asset class in India. Currently, BSE is the only major listed stock exchange, trading at specific valuation multiples. NSE's listing will provide an additional data point and potentially reset market expectations for how these businesses should be valued.

For the financial sector broadly, NSE's IPO validates the public market pathway for large, profitable institutions. After years of uncertainty about whether the listing would materialize, successful execution could encourage other financial market infrastructure providers to consider public listings.

The offering also represents a test of market depth and institutional appetite for mega-sized IPOs in India. A ₹20,000 crore-plus offering requires significant capital commitment from domestic and foreign institutional investors. The response will indicate the market's capacity to absorb large deals and could influence the pipeline of future offerings.

Conclusion

The National Stock Exchange has transitioned from IPO speculation to IPO execution with the formal issuance of offer for sale letters to shareholders. The mega-sized offering, potentially exceeding ₹20,000 crore, represents one of the largest public market transactions in Indian history.

The pure OFS structure, broad shareholder base, and dominant market position make this a unique offering with characteristics unlike typical IPOs. Eligible shareholders now have until April 27, 2026, to express their interest in participating, setting the stage for the next phases of documentation and regulatory approval.

As the exchange progresses toward filing its draft red herring prospectus and eventually opening for public subscription, market participants will gain detailed visibility into financial performance, risk factors, and valuation parameters. The success of this listing will have implications extending far beyond NSE itself, potentially reshaping perceptions about exchange valuations and infrastructure asset pricing in emerging markets.

For investors, the NSE IPO offers access to an institution that has been central to India's economic transformation over three decades. Whether the offering delivers attractive returns will depend on entry valuations, post-listing performance, and the exchange's ability to navigate evolving regulatory and competitive landscapes in the years ahead.
