NSE IPO: What is keeping retail investors cautious despite full subscription on Day 2?

The ₹22,562-crore initial public offering (IPO) of the National Stock Exchange of India (NSE) was fully subscribed on the second day of bidding, but failed to generate the same level of interest among retail investors. The portion reserved for retail investors received only 72% subscription at the close of bidding on September 18.

The overall issue received bids for 10.28 crore shares worth ₹18,350 crore against 8.86 crore shares on offer, resulting in a subscription of 1.16 times, according to BSE data. The issue received a total of 20,38,323 applications by the second day of bidding.

As per exchange data, the qualified institutional buyers (QIBs) portion was subscribed 1.53 times, while the non-institutional investors (NIIs) quota was subscribed 1.68 times. The employee portion was also subscribed 1.53 times.

The company has reserved 50% of the issue for QIBs, 15% for NIIs and the remaining 35% for retail investors.

The relatively subdued retail participation, compared with the other investor categories, stands out given the strong interest retail investors have shown in IPOs in recent years. So, what explains the slower response to NSE’s mega public offering?

Large minimum investment

One factor could be the relatively high minimum investment required for retail investors.

NSE has fixed the IPO price band at ₹1,700-₹1,785 per share, with a lot size of eight shares. At the upper end of the price band, a retail investor needs to commit at least ₹14,280 for one lot.

For investors looking to spread their money across multiple IPOs, the relatively high ticket size could be a consideration, particularly when the issue is one of the largest public offerings in India’s capital market.

The IPO is an offer for sale

Another important feature is that NSE is not raising fresh capital through the IPO. The issue comprises an offer for sale (OFS) of up to 12.64 crore existing shares. This means the proceeds will go to existing shareholders selling their stakes rather than to NSE for expansion or new projects.

For some investors, an OFS structure may be less compelling than a fresh issue, where the company receives the proceeds for growth or expansion.

The OFS structure, however, does not alter NSE’s underlying business or financial position; it primarily represents a change in ownership.

Valuation remains a key consideration

NSE has fixed the price band at ₹1,700-₹1,785 a share. At the upper end, the exchange is valued at around ₹4.42 lakh crore.

While NSE’s dominant position in India’s capital markets has attracted strong institutional demand, investors are also weighing the valuation against its earnings outlook and dependence on the derivatives segment.

Concerns around derivatives concentration

NSE derives a significant portion of its revenue from equity derivatives, making its exposure to the segment an important consideration for investors assessing the sustainability of earnings.

Regulatory changes affecting derivatives trading and the broader debate around options activity have added another layer of uncertainty to the exchange’s earnings outlook.

Brokerages have also flagged this concentration risk while highlighting NSE’s strong market position and cash-generating ability.

YES Securities said NSE derived 79% of its FY26 revenue from transaction charges, with options-related charges alone accounting for 60%. It noted that revenue growth was sluggish over FY24-26, although growth recovered to 13.1% year-on-year in the first quarter of FY27, led by a 15.6% rise in options transaction charges. The brokerage also sees scope for NSE to diversify into data, index licensing and clearing services.

Deven Choksey Research similarly flagged the concentration risk, noting that transaction charges account for 79% of revenue and equity options alone contribute 60%. It said the IPO valuation is not inexpensive and that the investment case depends more on earnings growth than on further multiple expansion.

Mirae Asset Sharekhan highlighted NSE’s over 90% market share across key trading segments and strong profitability, while noting that near-term earnings have been affected by regulatory costs and moderation in trading volumes.

Concerns over listing premium

Another consideration for retail investors could be the changing expectations around the listing premium.

The grey market premium (GMP) for the NSE IPO dropped sharply to ₹58 as of September 19, according to grey market tracking data. At the upper end of the price band, the GMP indicates an estimated listing price of around ₹1,843, implying a potential listing gain of about 3.25%.

The latest GMP is well below the recent high of ₹310. The premium has ranged between ₹142 and ₹310 over the past 15 sessions, indicating softer grey market expectations ahead of the listing.

GMPs are unofficial indicators and can change before listing; they do not guarantee the actual listing price or gains.

A narrowing premium could make the IPO less attractive to investors primarily seeking short-term listing gains, particularly when the issue requires a minimum investment of ₹14,280 for one lot.
