Grey Market Premium Signals Strong Demand for Mainboard IPOs

 Mainboard IPO momentum: India’s mainboard IPO market is showing stronger grey-market sentiment than smaller-company offerings. Recent mainboard issues such as Bombay Coated and Special Steels and M.K. Sons Fine Jewels recorded positive GMPs before listing, signalling investor willingness to pay above issue price.

Bombay Coated and Special Steels: Bombay Coated and Special Steels’ IPO carried a GMP of about 9.76 per cent before listing, implying an estimated listing price near the upper end of its ₹78–₹82 band. The issue later listed at ₹91 on NSE, a 10.98 per cent premium over its issue price.

M.K. Sons Fine Jewels: M.K. Sons Fine Jewels showed a GMP of roughly 6.17 per cent, or ₹10 per share, ahead of its November 4 listing. The premium indicated moderate but positive demand, even though its overall subscription level was comparatively modest at 5.09 times.

 SFC Environmental Technologies: SFC Environmental Technologies entered listing with a GMP of 4.70 per cent, suggesting a cautious but constructive market outlook. Its debut ultimately exceeded expectations, reinforcing the view that mainboard IPOs with positive grey-market readings can translate sentiment into listing gains.

Lenskart’s strong premium: Lenskart’s IPO GMP was around ₹67, implying an estimated listing gain of about 16 per cent over the upper price band. The elevated premium reflected near-term enthusiasm for one of India’s prominent consumer-internet listings, although GMP remains an unofficial market signal.

2026 listing performance: Mainboard IPOs listed in 2026 have averaged a 13.8 per cent listing-day gain over issue price, according to IPO Guru’s market tracker. That aggregate performance supports the narrative that larger, exchange-listed offerings are currently attracting firmer pre-listing demand than many SME issues.

GMP is unofficial: Grey market premium is the unofficial price at which IPO shares trade before formal listing; it is neither regulated by SEBI nor published by exchanges. It can change quickly and should be treated as a sentiment indicator, not a guaranteed forecast of the opening price.

Upcoming mainboard pipeline: Market trackers show eight upcoming mainboard IPOs, including National Stock Exchange of India, Adroit Industries, Srit India, German Green Steel and Power, and Runwal Enterprises. However, no mainboard issue was open for bidding as of November 11, making the near-term pipeline a key watchpoint.
