The NSE IPO's grey market premium (GMP) closed at around ₹300 on September 7, 2026, the final day before the six-month lock-in period for pre-IPO investors began, according to livemint.com. This GMP level reflects strong demand in the unlisted market, where NSE shares finished near ₹2,050 on the same day.
The GMP represents the price difference between the IPO's expected share price band and the price at which shares trade unofficially before listing. Experts explained that the NSE IPO's price band cannot exceed ₹1,750 due to mathematical valuation constraints. The GMP growth to ₹300 indicates investor optimism despite the price band cap, with pre-IPO investors offloading shares to avoid the lock-in restrictions.
This GMP movement is significant in the context of recent large IPOs where grey market premiums have served as an indicator of market sentiment. The ₹1,750 price band cap aligns with valuation models and market expectations, ensuring the IPO remains accessible to a broad investor base. The NSE IPO's GMP performance places it among notable recent offerings that saw strong pre-listing demand.
The lock-in period for pre-IPO investors commenced on September 8, 2026, restricting share sales for six months. This regulatory measure aims to stabilize post-listing trading and protect retail investors. The NSE IPO's final price band and listing date are expected to be announced shortly, completing the public offering process.
