Is IPO GMP Accurate? We Checked 104 IPO Listings

We compared the last grey market premium (GMP) recorded before listing with the actual listing-day opening price of 104 Mainboard and SME IPOs listed 31 December 2025 – 8 October 2026. Here's how often GMP got it right — and by how much it missed.

70% of IPOs with a positive GMP listed above the issue price
7.8 pp median gap between GMP-implied and actual listing gain
59% listed within ±10 percentage points of their GMP
3.2 pp median amount GMP overestimated the listing gain

Key findings

  1. GMP gets the direction right more often than not. When the last GMP was positive, the IPO opened above its issue price 69.9% of the time (Mainboard 73.8%, SME 63.2%).
  2. It tends to run a little hot. The average GMP implied a 21.8% listing gain; the average actual gain was 18.8%. The median IPO listed 3.2 percentage points below its GMP.
  3. A small GMP is close to a coin toss. When GMP implied a gain of 0–10%, only 43.9% of IPOs actually listed above the issue price, and the median listing gain was 0.0%.
  4. A big GMP is a strong signal — but not of the exact number. Every IPO with a GMP above 50% listed at a premium, yet the median listing gain (+56.1%) was well below the average GMP-implied +73.0%.
  5. GMP is more reliable for Mainboard than SME. 71.2% of Mainboard IPOs listed within 10 points of their GMP, versus 36.8% of SME IPOs (median miss 6.1 vs 16.2 points).

GMP-implied gain vs actual listing gain

Each dot is one IPO. Dots on the dashed line listed exactly where GMP pointed; dots below it listed lower than GMP implied. Correlation: r = 0.77. The SME cluster at +90% is the exchanges' cap on an SME IPO's listing-day opening price (90% above the issue price) — for those IPOs, GMP was capped by the rules, not wrong by that much.

Frequently asked questions

Is IPO GMP accurate?

Directionally, mostly. In our study of 104 IPO listings, a positive GMP was followed by a listing above the issue price 69.9% of the time. As a precise forecast it is rough: the median gap between the GMP-implied gain and the actual listing gain was 7.8 percentage points.

Does GMP overestimate listing gains?

Slightly, on average. The median IPO listed 3.2 percentage points below what its last GMP implied, and the average GMP-implied gain was 21.8% against an average actual gain of 18.8%.

Is GMP more reliable for Mainboard or SME IPOs?

Mainboard. 71.2% of Mainboard IPOs listed within 10 percentage points of their GMP, compared with 36.8% of SME IPOs.

Should I apply for an IPO based on GMP?

GMP is an unofficial, unregulated indicator of demand and can change sharply in the last days before listing. Use it as one signal alongside the company's financials, valuation and subscription data — not as a guarantee of listing gains.
