A Much-Awaited IPO Opens Amid Cooling Sentiment

The much-awaited initial public offering of the National Stock Exchange of India (NSE) opened for public subscription on Thursday, even as its grey market premium (GMP) has come under sustained pressure over the past week, tempering some of the enthusiasm that had initially surrounded the issue.

Tracking the GMP's Decline

According to market reports, NSE's GMP stood at Rs 218 per share on September 11. It subsequently moved to Rs 208 on September 12, Rs 210 on September 13, Rs 208 on September 14, before dropping more sharply to Rs 160 on September 15 and Rs 145 on September 16. The premium was quoted at Rs 125 per share on September 17, before recovering to around Rs 148 by 3 pm on Thursday, the day subscription opened.

A Notable Week-on-Week Decline

Despite this intra-day recovery, the GMP remains significantly below the level seen a week earlier, indicating a decline of nearly 32 per cent over the period. This sustained downward movement, even accounting for the partial recovery on listing day itself, suggests that investor sentiment around the issue has cooled meaningfully compared to where it stood in the run-up to subscription.

Understanding What GMP Actually Signals

The grey market premium is an unofficial indicator of the premium investors may be willing to pay over an IPO's issue price before the shares are formally listed. However, it is worth noting that GMP is not an official market metric and does not guarantee that the stock will actually list at a premium once trading begins, making it a useful but imperfect gauge of pre-listing sentiment rather than a reliable predictor of listing-day performance.

Subscription Window and Pricing Details

The NSE IPO will remain open for retail and other eligible investors until September 21. The exchange has fixed the price band at Rs 1,700-1,785 per share. At the upper end of this price band, the issue is valued at around Rs 22,561.57 crore, with 12.64 crore shares being offered to investors as part of the sale.

An Offer for Sale, Not a Fresh Issue

The issue is structured entirely as an offer for sale (OFS), meaning that the proceeds from the share sale will go to existing shareholders rather than to NSE itself. This distinction is significant for investors to understand, since an OFS does not raise fresh capital for the company's own operations or expansion, unlike a traditional fresh issue of shares.

Financial Performance Under Scrutiny

Apart from the subdued grey market sentiment, investors are also likely to closely assess NSE's recent financial performance while evaluating the issue. The exchange reported revenue from operations of Rs 16,601.31 crore in FY26, compared with Rs 17,140.67 crore in FY25, marking a decline of more than 3 per cent year-on-year.

A Decline in Key Transaction Revenue

Revenue from transaction charges, one of NSE's key sources of income, also declined during the period. It fell to Rs 13,057.01 crore in FY26 from Rs 13,635.76 crore in FY25, representing a year-on-year decline of around 4 per cent. Given that transaction charges make up a substantial portion of NSE's overall revenue, this decline is likely to draw particular attention from prospective investors weighing the exchange's growth trajectory against the backdrop of a cooling grey market premium heading into the subscription period.
