What is IPO GMP? How Grey Market Premium Works in India

If you've ever explored IPOs in India, you’ve probably come across the term IPO GMP, short for Grey Market Premium. For many retail investors, IPO GMP serves as an early indicator of how an IPO might perform on its listing day. But what exactly is IPO GMP, and how does it work in the Indian market?

In this blog post, we'll break down what is IPO GMP, how the grey market functions, and how to use it wisely when deciding to apply for an IPO.

📌 What is IPO GMP?

IPO GMP (Grey Market Premium) is the premium amount at which shares of an IPO are traded unofficially before their official listing on the stock exchaanges like NSE or BSE.

Let’s say a company is offering its shares in an IPO at ₹100, and in the grey market, those shares are being traded at ₹120. That means the GMP is ₹20. This premium reflects investor sentiment and the perceived demand for the IPO.

🕵️ What is the Grey Market?

The grey market is an unregulated and unofficial market where IPO shares are bought and sold before they are formally listed. This market operates outside the purview of SEBI (Securities and Exchange Board of India) and stock exchanges.

While it's not illegal to observe or discuss GMP, trading in the grey market is unofficial and unregulated, meaning there’s no legal protection for buyers or sellers.

🧮 How is IPO GMP Calculated?

IPO GMP is determined by market demand and investor sentiment. There’s no formal process or institution calculating it. Instead, GMP information is based on deals struck between IPO investors, brokers, and dealers who operate in this grey zone.

🔹 Formula:

Estimated Listing Price = IPO Price + IPO GMP

For example:

• IPO Issue Price: ₹100
• GMP: ₹30
• Estimated Listing Price: ₹130

💡 Types of Grey Market Transactions

There are mainly two types of grey market transactions:

1. GMP Deals (Grey Market Premium Only)

In this transaction, the seller agrees to sell IPO shares at a fixed premium. If shares are allotted, the seller delivers them to the buyer at the agreed GMP. If not allotted, the deal is canceled.

1. KOSTAK Rate

Kostak is the premium a person gets for selling their entire IPO application. This means an investor can sell their IPO application before allotment, regardless of whether the shares are allotted or not.

Example: If the Kostak rate is ₹500 and you applied for 1 lot of an IPO, you can sell your application for ₹500 to someone else who will benefit if you get the allotment.

📊 Why IPO GMP is Important

• Investor Sentiment: A high GMP reflects strong interest in the IPO.
• Listing Day Expectations: Helps predict potential listing gains.
• Demand Indicator: GMP often rises with oversubscription numbers, especially in QIB and HNI categories.

🚫 Limitations of IPO GMP

While IPO GMP can be a useful tool, it's important to understand its limitations:

• Unregulated & Risky: No legal framework protects investors in grey market transactions.
• Not Always Accurate: GMP doesn’t always reflect the actual listing price or long-term performance.
• Manipulation Possibility: GMP can be artificially inflated to create hype.

Disclaimer: IPO GMP is purely speculative. Use it only as a reference, not as a guarantee of returns.

✅ Best Practices for Using IPO GMP

• Use GMP only as a sentiment indicator, not for final investment decisions.
• Focus on company fundamentals, valuation, and sector outlook.
• Track subscription status across retail, HNI, and QIB categories.
• Always read the RHP (Red Herring Prospectus) before applying.
