₹22,561 crore raised, zero rupees to NSE: a 100% Offer for Sale means every paisa goes to selling shareholders, not the exchange.
MUMBAI: The initial public offering of the National Stock Exchange of India closed for subscription on September 21, 2026, capping a bidding window that began September 17 and drew sharply divergent responses from institutional and retail investors. The issue, structured entirely as an Offer for Sale worth up to ₹22,561.57 crore at the upper price band of ₹1,785 per share, ranks as the second-largest public offering in Indian capital markets history, trailing only Hyundai Motor India’s ₹27,859 crore issue in 2024.
Because the transaction is a pure OFS with no fresh issue component, NSE itself receives none of the proceeds; the entire sum flows to selling shareholders. The offer comprises 12,64,36,650 equity shares, roughly 5.11% of the exchange’s total paid-up capital of 247.5 crore shares, implying an equity valuation between ₹4.21 lakh crore and ₹4.42 lakh crore or approximately $46 billion at the top end. In a detail that underscores the peculiarities of exchange regulation, NSE’s shares will list exclusively on rival BSE Limited, since SEBI rules prohibit an exchange from listing on its own trading platform.
Institutions Came Late, But They Came Hard
Subscription data through the bidding window revealed a familiar but pronounced pattern. Qualified Institutional Buyers subscribed just 0.19 times on the opening day, before surging to 3.72 times by early afternoon on the final day. Non-institutional investors followed a similar trajectory, climbing from roughly 0.70 times on Day 1 to 3.58 times by the close. Retail investors, by contrast, built demand gradually and only reached full subscription, 1.00 times, during the afternoon of the final bidding day, a comparatively muted response that analysts attribute partly to the ₹14,280 minimum retail ticket size and a crowded primary market calendar competing for the same capital.
The anchor round, completed a day ahead of the public opening, told its own story. NSE allocated shares worth ₹6,746.18 crore to 189 institutional anchors at the top price band, with foreign portfolio investors taking the largest share at 42.73%, followed by domestic mutual funds at 36.98%. Perhaps the most notable signal came from Life Insurance Corporation of India, which chose not to sell a single share from its existing 10.72% stake in the OFS, instead committing over ₹500 crore in fresh capital through the anchor allocation, a move that reads as a clear vote of confidence from India’s largest institutional investor.
The Grey Market Cooled as Bidding Progressed
Unofficial grey market premiums, which had signalled listing gains as high as 15.8% in early September before the price band was finalised, compressed steadily through the bidding window, falling to between ₹52 and ₹113 by the close on September 21, implying gains closer to 3% to 6%. Analysts point to three factors behind this cooling: the sheer scale of paper requiring absorption, over ₹22,500 crore, broader secondary market volatility through mid-September, and institutional recalibration of NSE’s earnings outlook following SEBI’s tightening of index options regulations. It is worth noting that grey market figures remain informal and non-binding, offering an indicative rather than definitive read on post-listing performance.
Why the Valuation Carries a Built-In Discount
At the upper price band, NSE is priced at a Price-to-Earnings multiple of roughly 35.4 to 42.9 times FY26 earnings, a noticeable discount to domestic peer BSE Limited, which trades at 46.9 to 50.5 times. This gap exists despite NSE posting a considerably higher net operating margin of 62.05% against BSE’s 47.38%, and stems chiefly from NSE’s slower revenue growth. The exchange’s operating revenue actually declined 3.15% year-on-year in FY26 to ₹16,601.31 crore, while net profit fell 15.47% to ₹10,302.06 crore, largely because SEBI’s regulatory changes, including larger options contract lots and rationalised weekly expiries, curbed retail derivatives trading. NSE’s share of the equity options market consequently slipped from 96.86% in FY24 to 74.71% in FY26, ceding ground to BSE. Against global exchanges such as Nasdaq, the London Stock Exchange Group and Hong Kong Exchanges, which trade between 24 and 34 times earnings, NSE still commands a premium, reflecting continued optimism about India’s long-term market growth given equity penetration of only around 13.5% of the population.
What a Decade-Long Wait Reveals
The listing itself closes out an unusually long regulatory journey. NSE first filed IPO papers in 2016, only for the process to stall amid SEBI investigations into alleged preferential co-location access for algorithmic trading firms, followed by governance overhauls and scrutiny after technical outages in 2021 and a denial-of-service incident in 2025. SEBI finally cleared a fresh prospectus on September 4, 2026, paving the way for this listing.
What Comes Next
Trading is scheduled to begin on BSE on September 24, 2026 and several questions will shape how the stock performs from there. Because the entire tradable float equals the OFS size, just over 5% of total equity, secondary market liquidity will face an early test in absorbing that supply without sharp price swings. Longer term, investors will be watching whether NSE’s options market share stabilises against BSE’s gains, how the exchange manages its dividend policy, having already declared an interim payout of ₹160 per share for FY27, and how future SEBI directives on derivatives and clearing fund requirements shape earnings from what remains, at its core, a highly profitable but increasingly regulation-sensitive market utility.
