The initial public offering of the National Stock Exchange of India has gathered significant investor interest on the second day of bidding, with the Rs 22,562 crore issue becoming fully subscribed by Friday afternoon, September 18, 2026. The strong demand was largely supported by institutional investors as the country's largest stock exchange moves closer to its proposed public listing.
The NSE IPO opened for subscription on Thursday, September 17, and the bidding window will remain open until Monday, September 21. According to exchange data reported on Friday afternoon, investors had placed bids for around 8.83 crore shares against approximately 8.86 crore shares available under the public issue. Reuters reported that the issue was fully subscribed by the second day, with institutional demand playing a major role.
The IPO has a size of approximately Rs 22,561.57 crore, according to IPO details published by The Economic Times. The price band has been fixed at Rs 1,700 to Rs 1,785 per equity share, while the minimum retail lot consists of eight shares. At the upper end of the price band, a retail investor applying for one lot would need Rs 14,280, excluding applicable charges.
One of the key features of the NSE IPO is that it is entirely an Offer for Sale. There is no fresh issue of shares. Existing shareholders are offering their shares to public investors, and therefore NSE itself will not receive the IPO proceeds. The money raised through the offering will go to the shareholders selling their stakes.
The IPO has attracted considerable attention because it represents the proposed public listing of the National Stock Exchange, one of India's major financial market institutions. The exchange operates trading and related market infrastructure across several asset classes, including equities, derivatives, currency derivatives, debt securities and other financial products.
Investor participation has varied across categories during the first two days of bidding. On the first day, the IPO was subscribed 0.43 times overall, with the non-institutional investor category recording 0.72 times subscription. Retail investors subscribed 0.44 times, while the qualified institutional buyer category excluding anchors stood at 0.19 times at the end of September 17.
Demand strengthened considerably on the second day. Moneycontrol reported that by Friday, the NII portion had moved above its reserved quota, while institutional and retail participation also increased. At one stage, the overall subscription was reported at 0.90 times, before further bids took the issue to full subscription.
Reuters subsequently reported that the IPO had received bids for about 88.3 million shares against approximately 88.6 million shares on offer by 2:44 pm IST on September 18. The report said the issue was fully subscribed on the second day, with institutional investors providing strong demand.
The IPO reservation structure includes separate portions for qualified institutional buyers, non-institutional investors, retail individual investors and eligible employees. The IPO details show that approximately 4.41 crore shares have been reserved for retail investors, while around 1.89 crore shares are allocated to the non-institutional investor category. The employee reservation stands at about 4.33 lakh shares.
For investors who are tracking the issue, the IPO timeline is another important factor. The bidding period will close on September 21. The basis of allotment is expected to be finalised on September 22. Refunds or unblocking of funds for applicants who do not receive shares are expected to begin on September 23. Shares allotted to successful applicants are also expected to be credited on September 23, while trading is scheduled to begin on September 24, subject to the final exchange and regulatory process.
The NSE IPO is being offered at a price band of Rs 1,700 to Rs 1,785. Investors applying through the retail category can bid for a minimum of eight shares. The final price within the band will determine the amount payable for allotted shares.
The issue has also generated interest in the unlisted market, where the grey market premium has been closely tracked by investors. However, grey market premiums are unofficial indicators and are not guaranteed to reflect the eventual listing price. They can change significantly before listing and should therefore be treated separately from the formal IPO subscription data.
Another important point is that the IPO does not result in a fresh infusion of capital into NSE. Since it is an offer for sale, the transaction primarily provides an opportunity for existing shareholders to sell part of their holdings to public investors. The company will not receive the proceeds generated from the sale of those shares.
The strong subscription on the second day comes during a period of significant activity in India's primary market. Large public offerings have attracted attention from institutional as well as retail investors, while companies and existing shareholders have continued to assess market conditions for fundraising and stake sales.
Investors should also distinguish between subscription data and the eventual performance of the stock after listing. A heavily subscribed IPO does not by itself determine the price at which shares will trade after listing. The listing price will depend on market conditions, investor demand, broader equity-market sentiment and the company's valuation at the time of listing.
For NSE IPO applicants, the immediate focus will now be on the completion of the subscription period on September 21, followed by the allotment process on September 22. Applicants who receive shares are expected to see the securities credited to their demat accounts on September 23, while funds for unsuccessful applications are expected to be unblocked or refunded around the same time.
The shares are scheduled to begin trading on the BSE on September 24. The Economic Times IPO dashboard lists September 22 as the expected allotment date, September 23 as the refund and share-credit date, and September 24 as the listing date.
The NSE IPO's second-day subscription marks a significant development in the public issue process. While the offering has already received bids covering the shares available, investors will be able to participate until the official closing time on September 21. Final subscription figures will therefore depend on the bids received during the remaining portion of the issue period.
