What happened
NSE priced its IPO at ₹1,700-1,785 per share, opening for subscription on September 17, 2026, raising ₹22,569 crore through an offer-for-sale.
National Stock Exchange of India has priced its IPO at ₹1,700-1,785 per share, opening for subscription on September 17, 2026. At the upper band, the exchange — India's largest — looks strikingly cheap compared to peer BSE, trading at roughly a 30% discount on FY27 earnings estimates.
The catch is in the derivatives ledger. NSE's share of the equity options premium market collapsed from nearly 97% in FY24 to 68.5% in Q1FY27 after SEBI's single-weekly-expiry rule forced liquidity toward BSE. Monthly derivatives turnover has since fallen from ₹42.6 trillion in July 2026 to ₹33.5 trillion in August — its lowest since November 2023.
With recurring revenue from colocation, data feeds and index licensing contributing less than 12% of total income, the question for retail investors is whether the apparent valuation discount masks a structural earnings problem rather than a temporary dip.
The Valuation Paradox
The NSE IPO presents a classic valuation paradox: it is simultaneously the cheapest large-cap financial listing in recent memory at ~30% below BSE, and one of the most exposed to regulatory disruption in the derivatives segment that drives over 60% of its revenue.
- ~30% discount to BSE on FY27 earnings estimates at ₹1,785 upper band
- Options transaction revenue accounts for more than 60% of operating revenue
CAS and the Derivatives Reset
SEBI's regulatory timeline — from the single-weekly-expiry rule in late 2024 to the Closing Auction Session in August 2026 — has progressively reshaped NSE's derivatives franchise. The August 2026 turnover drop to ₹33.5 trillion marks the sharpest monthly decline since November 2023.
- SEBI single-weekly-expiry rule (late 2024): options premium share began shifting to BSE
- SEBI CAS (August 2026): monthly derivatives turnover fell ₹42.6T → ₹33.5T
Why it matters for me
The valuation discount to BSE may mask a structural problem: NSE's equity options premium market share has collapsed from 97% to 68.5% after SEBI regulatory changes, and derivatives turnover has fallen by ₹9.1 trillion month-over-month.

NSE IPO appears ~30% cheaper than BSE on FY27 earnings estimates, but the discount may reflect structural derivatives weakness rather than genuine value.

SEBI's single-weekly-expiry rule and CAS have cut NSE's options market share from 97% to 68.5% and derivatives turnover by ₹9.1 trillion month-over-month, affecting trading volumes and brokerage economics.

NSE's recurring-revenue businesses (colocation, data, index licensing) grew 18% annually but contribute under 12% of total revenue, limiting the buffer against derivatives headwinds.
What to remember
The NSE IPO may look cheap on paper, but the real test is whether the exchange can offset derivatives headwinds with its still-small recurring-revenue businesses.
NSE IPO at ₹1,785 looks 30% cheaper than BSE, but the catch is a derivatives share collapse from 97% to 68.5%. Is this a bargain or a trap?
