The National Stock Exchange (NSE) is reportedly preparing to open its massive nearly Rs 30,000-crore initial public offering for public subscription on September 18, with a planned market debut on September 25, according to source reports. This offering is positioned to surpass previous records to become India’s largest public listing.
The Bottom Line
- Record-Breaking Scale: The public issue aims to raise approximately Rs 30,000 crore, eclipsing Hyundai Motor India’s 2024 offering of Rs 27,870 crore.
- Strict Timetable Constraints: Sources indicate the exchange aims to list shares before the commencement of the 16-day lunar period ‘Pitru Paksha’ on September 26.
- Pure Offer for Sale: The transaction consists entirely of an offer for sale (OFS) of up to 148.9 million equity shares, meaning the exchange will raise zero primary capital from the event.
Mapping the IPO Timeline and Structure
Market watchers anticipate that the official price band will be revealed on September 15. This announcement will precede the anchor investor book building scheduled for September 17. If the current schedule holds true, the public subscription window will remain active across September 18, September 21, and September 22, leading up to the target listing date on September 25.
The offering represents an offer for sale of up to 148.9 million equity shares with a face value of Rs 1 each. This volume accounts for roughly 6 percent of the exchange’s paid-up equity capital. Because the transaction involves no fresh issuance of shares, the corporate entity itself will not bank any capital proceeds from the offering. Instead, existing stakeholders looking to liquidate portions of their holdings will capture the liquidity.
According to recent reporting, Bank of Baroda (NSE: BANKBARODA) is expected to divest 35% of its holding in the exchange, equating to 7,690,375 shares sold through the OFS mechanism.
Regulatory Clearance and Market Positioning
This market debut has been in development for nearly a decade. The timeline cleared a major hurdle when the Securities and Exchange Board of India (SEBI) issued its regulatory clearance. This regulatory green light cleared the path for the exchange to advance its public offering plans.

As the dominant player in domestic financial infrastructure, the exchange operates the benchmark Nifty 50 index and commands the position of India’s largest stock exchange by trading activity. Furthermore, international metrics designate the platform as the world’s most active derivatives exchange when measured by the number of contracts traded.

Navigating Calendar Pressures
