The full form of IPO is Initial Public Offering.
In the Indian stock market, an Initial Public Offering (IPO) is the process through which a privately owned company offers shares to the public for the first time, listing on stock exchanges such as the National Stock Exchange (NSE) or Bombay Stock Exchange (BSE) to raise equity capital.
1. Understanding the Three Words: "Initial", "Public", "Offering"
The Very First Time
Prior to an IPO, the company's shares were owned privately by founders, family, and venture capitalists. "Initial" signifies that this is the inaugural occasion these equity shares are offered to general public market participants.
Open to All Investors
The offer is open to all categories of public investors—from retail individuals applying with ₹15,000 via UPI to multi-billion-dollar domestic mutual funds and global institutional pension managers.
Sale of Equity Shares
The company makes a formal statutory offer to sell ownership units (equity shares) at a designated price band, enabling buyers to become part-owners of the enterprise.

3. Deep Dive into the 4 Most Confusing IPO Acronyms
1. GMP (Grey Market Premium)
Quoted informally in rupees per share before official listing. If an IPO issue price is ₹500 and its GMP is ₹150, the estimated listing price is ₹650 (+30% gain). Read our dedicated What is IPO GMP Guide.
2. ASBA (Application Supported by Blocked Amount)

4. OFS (Offer for Sale) vs. Fresh Issue
