The grey market premium (GMP) for the National Stock Exchange's (NSE) Rs 22,562 crore IPO has seen a significant decline despite the issue being fully subscribed by the second day of bidding.
As of September 18, the IPO was subscribed 1.15 times, driven primarily by qualified institutional buyers (QIBs) and non-institutional investors (NIIs). The QIB portion was subscribed 1.32 times, while the NII portion saw subscriptions between 1.36 and 1.44 times. However, retail subscription lagged at around 66-68%.
The IPO, which opened on September 17 and is set to close on September 21, is entirely an offer for sale (OFS), meaning NSE will not receive any fresh capital from the issue. Existing shareholders are selling approximately 12.64 crore shares, with the price band set at Rs 1,700-1,785 per share. The stock is expected to list on the BSE on September 24.
“The massive size and absence of a fresh-issue growth engine could mean upside 'right out of the gate may be more measured compared with smaller, high-growth niche IPOs.'”

The sharp fall in GMP indicates more sober listing expectations. Analysts suggest that the large size of the IPO, being over Rs 22,500 crore, could absorb significant demand and limit extreme listing gains. The absence of a fresh-issue growth engine further tempers expectations for immediate upside.
The structure of the IPO as an OFS has become a focal point for investors, as it does not directly fund expansion or new business lines. Instead, proceeds go to selling shareholders, shifting the focus to price discovery and liquidity.
Subscription trends show decent but not euphoric demand. The issue was 42% subscribed on the first day, with retail and NII demand initially outpacing institutional interest. By the second day, full subscription was achieved, although retail demand remained below full subscription levels.
Background
NSE is one of India's leading market infrastructure businesses, and its IPO has been long-awaited. The decision to structure the IPO as an OFS means that the proceeds will not be used for growth initiatives, which is a departure from typical IPOs that raise capital for expansion.
Looking ahead, investors should monitor the final subscription figures and the impact of the OFS structure on listing gains. The market will also be watching for any regulatory changes affecting NSE's revenue streams, particularly from options transactions.
