Reading this GMP history
How the GMP moved
The first grey market reading in our record for the Bench Mark Infotech Services IPO came in at ₹0 on 19 Sept 2026. The premium peaked at ₹29, roughly +26.4% on the issue price on 28 Sept 2026. The final reading before listing was ₹25, dated 5 Oct 2026. Start to finish, over 17 days, that is a net rise of ₹25 per share. Day-end readings ranged between ₹0 and ₹29 across 17 days of data — a band of ₹29 that shows how much dealer sentiment shifted while the quote was live.
GMP versus the actual listing
Going into listing day, the final premium of ₹25 implied a debut near ₹135 against the issue price of ₹110. The stock actually debuted at ₹110, a listing gain of +0.0% on the issue price. That puts the actual debut ₹25 below what the final premium implied — a gap worth noting when weighing how much signal GMP carried for this issue.
Kostak and subject-to-sauda
The grey market in this issue went beyond the share premium to application-level deals. The subject-to-sauda rate — what a buyer pays for an application that is honoured only if it wins allotment — was last quoted at ₹22,800 per application as of 4 Oct 2026. Unlike a kostak deal, where an application changes hands at a fixed price regardless of the outcome, a sauda payout depends entirely on the allotment draw. At the prevailing premium, the dealer-estimated profit per lot stood at ₹30,000 on a lot of 1200 shares. Both metrics come from the same dealer network as the GMP itself and move with it.
