NSE Mega IPO: Everything to Know About the ₹30,000 Crore Offering

The National Stock Exchange (NSE) is set to trigger a historic milestone in the Indian capital markets with its upcoming Initial Public Offering (IPO). By filing its Draft Red Herring Prospectus (DRHP), the exchange has signaled its intent to launch a massive public issue that could redefine the scale of corporate debuts in India.

A Potential Record-Breaker for India's IPO Market

The scale of the NSE IPO is unprecedented. The exchange has filed to issue up to 148,905,525 equity shares of Rs 1 each, with an estimated issue size of approximately ₹30,000 crore. If successfully completed, this offering will eclipse the current record held by Hyundai Motor India, which raised ₹27,859 crore in October 2024. This move positions the NSE to become the largest corporate market debut in the history of the Indian stock market.

Structure of the Issue: A Pure Offer for Sale

According to the DRHP filed with the Securities and Exchange Board of India (SEBI), this is not a fresh issue of shares to raise new capital for the exchange. Instead, it is structured as a "pure offer for sale" (OFS). This means the proceeds from the IPO will go entirely to the existing shareholders who are divesting their stakes, rather than to the NSE itself.

The selling shareholders include a mix of major financial institutions and public sector entities:

  • State Bank of India (SBI): The largest seller, divesting 24.75 million shares.
  • Foreign Institutional Investors: MS Strategic (Mauritius) Limited (16 million shares) and the Canada Pension Plan Investment Board (11.87 million shares).
  • Public Sector Entities: Bank of Baroda (10.98 million shares) and several state-owned insurers, including General Insurance Corporation of India (10.66 million shares) and The New India Assurance Company Ltd (10.50 million shares).

Global Dominance and Financial Performance

The IPO comes at a time when the NSE is cementing its status as a global financial powerhouse. Data from the World Federation of Exchanges highlights that the NSE remains the world’s largest equity derivatives exchange, having recorded over 36.99 billion contracts traded in Fiscal 2026. It also ranks as the third-largest globally by number of cash equity trades.

Financially, the exchange continues to demonstrate robust numbers, despite slight fluctuations in year-on-year revenue. For the fiscal year ending March 31, 2026, the NSE reported:

  • Total Income: ₹187,133.70 million.
  • Revenue from Operations: ₹166,013.09 million.
  • Net Profit: ₹103,020.61 million.

While total expenses rose to ₹59,999.03 million in FY26, the exchange maintained a healthy profit margin, ensuring it remains a highly attractive entity for institutional and retail investors alike.

Key Takeaways

  • Market Milestone: At an estimated ₹30,000 crore, the NSE IPO is poised to become the largest IPO in Indian history, surpassing Hyundai Motor India.
  • OFS Model: The offering is a pure Offer for Sale (OFS), meaning existing shareholders like SBI and various public sector insurers are divesting their stakes.
  • Global Leader: The exchange enters the public market as a global leader, holding the title of the world's largest equity derivatives exchange.
