What is IPO GMP (Grey Market Premium) Today?

IPO GMP stands for Grey Market Premium — the price at which IPO shares are traded in the unofficial grey market before they officially list on NSE or BSE.

Kostak Rate and Subject to Sauda — Explained

📋 Kostak Rate
The price at which an entire IPO application is bought or sold in the grey market — regardless of allotment status. Example: Kostak of ₹800 means you earn ₹800 per application sold, allotment or not.
📌 Subject to Sauda (Sub2Sauda)
A grey market deal where payment is made only if the seller receives IPO allotment. Sub2Sauda rates are always higher than Kostak rates because the buyer takes on allotment risk.

Is IPO GMP Reliable for Predicting Listing Price?

GMP is a sentiment indicator — not a guarantee. Always check subscription data, company financials, valuation vs peers, and anchor investor quality.
