What is Mainboard IPO?
A Mainboard IPO is the process where a well-established company raises capital by offering its shares to the public on major stock exchanges like the BSE (Bombay Stock Exchange) and NSE (National Stock Exchange). Companies listed under Mainboard IPOs are larger and must meet strict eligibility criteria set by SEBI, including financial performance, profitability, and minimum paid-up capital requirements.
In a Mainboard IPO, a company offers shares to different types of investors—retail, qualified institutional buyers (QIBs), and non-institutional investors (NIIs). Investors apply during the IPO subscription period, and after the allotment process, the shares get listed on the stock exchange. Once listed, these shares can be traded in the open market.
Mainboard IPOs at BSE and NSE attract investors looking for stable, high-growth opportunities. They provide companies with funds for expansion while offering investors a chance to own a stake in established businesses with proven track records.

How to Apply for Mainboard IPOs in India?
Investing in a Mainboard IPO is easy and can be done through your Demat and trading account. Follow these steps to apply:
Step 1: Choose a Stockbroker
To apply for a Mainboard IPO at BSE or NSE, you need a Demat account with a SEBI-registered broker like Zerodha, Groww, Upstox, ICICI Direct, or Angel One.
Step 2: Check the IPO Details
Before applying, research the IPO thoroughly. Check:
Issue Price & Lot Size
Subscription Dates
Financials & Business Model
GMP (Grey Market Premium) for market sentiment
Step 3: Apply via UPI or ASBA
You can apply using UPI (Unified Payments Interface) or ASBA (Application Supported by Blocked Amount) via net banking.
UPI Method (For Retail Investors):
Log in to your broker’s app (e.g., Zerodha, Groww).
Select the IPO and enter bid details (lot size, price).
Enter your UPI ID and submit.
Approve the UPI mandate request in your UPI app.
ASBA Method (For Bank Customers):
Log in to your net banking.
Go to ‘IPO’ or ‘ASBA Services’.
Select the IPO and enter details.
The amount gets blocked in your account until allotment.
Step 4: Wait for IPO Allotment
After the subscription closes, check IPO allotment status on the registrar’s website (e.g., Link Intime or KFintech).
If allotted, shares are credited to your Demat account.
If not allotted, the blocked funds are released.
Step 5: Listing & Trading
On the listing day, shares start trading on BSE/NSE.
You can hold or sell based on market performance.
Benefits of Investing in Mainboard IPO
Investing in Mainboard IPOs at BSE and NSE offers multiple advantages for both short-term and long-term investors:
1. Early Entry into a Growing Business
Buying shares in an IPO allows you to invest in a company before it becomes widely available on the stock market. If the company performs well, early investors can benefit from significant price appreciation.
2. Potential for Listing Gains
Many IPOs list at a premium, meaning the share price on the listing day is higher than the issue price. Investors who receive an allotment can sell their shares on the first day and earn quick profits from listing gains.
3. Long-Term Wealth Creation
Investing in IPOs can be a great way to build long-term wealth, especially if you invest in companies with strong fundamentals, high growth potential, and industry leadership.
4. Transparency and Regulation
Mainboard IPOs are strictly regulated by SEBI (Securities and Exchange Board of India), ensuring that companies meet financial and operational requirements before going public. This reduces the risk of fraud.
5. Price Advantage
IPO shares are often priced lower than post-listing market prices, giving early investors a chance to buy at a competitive rate before the stock starts trading.
6. Portfolio Diversification
Mainboard IPOs come from different industries, allowing investors to diversify their portfolios with new-age businesses, emerging leaders, and high-growth sectors.
7. Higher Liquidity
Since Mainboard IPOs are listed on NSE and BSE, investors can easily buy and sell shares after listing, ensuring high liquidity compared to unlisted or SME stocks.
8. Stronger Corporate Governance
Companies going public must follow strict corporate governance and disclosure norms, making them more accountable and transparent to investors.
Risks of Investing in Mainboard IPOs
While Mainboard IPOs at BSE and NSE offer significant opportunities, they also come with risks. Here are some key risks investors should consider before applying for an IPO:
Market Volatility Risk: IPO share prices can be highly volatile, especially on the listing day. Sudden market downturns can impact IPO performance, even if the company is strong.
Listing Loss Risk: Not all IPOs deliver listing gains. Some stocks list below their issue price, causing immediate losses to investors. Poor market sentiment or overpricing can lead to a weak debut.
Business Performance Uncertainty: Newly listed companies have limited public financial history, making it harder to predict long-term performance. Some companies may struggle with post-IPO execution and growth.
Oversubscription & Allotment Risk: Highly popular IPOs get oversubscribed, reducing the chances of retail investors getting an allotment. Investors may receive fewer shares than applied for or no allotment at all.
Lock-in Period for Pre-IPO Investors: Promoters, early investors, and institutional backers have a lock-in period. If they sell large stakes after the lock-in ends, the stock price may decline.
SEBI & Regulatory Risks: Companies must comply with SEBI’s regulations, but any non-compliance issues post-listing can affect stock prices. Changes in government policies or taxation laws may impact IPO performance.
Liquidity Risk: Some IPOs may have low trading volumes after listing, making it difficult for investors to sell shares quickly.
Hype vs. Reality: IPOs often generate excitement, but some may not justify their valuations. Investors should evaluate financials, industry trends, and management quality before investing.
Mainboard IPO Subscription Status
The Mainboard IPO subscription status shows how many times an IPO has been subscribed by different investor categories—Retail Investors (RII), Qualified Institutional Buyers (QIBs), and Non-Institutional Investors (NIIs).
This data is updated daily during the IPO subscription period and indicates investor demand. A higher subscription ratio suggests strong interest, potentially leading to listing gains. Investors can check real-time Mainboard IPO subscription status on NSE, BSE, or the IPO registrar’s website. It helps in assessing market sentiment before applying.
Mainboard IPO Allotment Status
The Mainboard IPO allotment status determines whether an investor has received shares after applying. Once the subscription period ends, shares are allotted based on demand, with retail applicants usually allocated through a lottery system.
Investors can check their IPO allotment status on the registrar’s website (e.g., Link Intime, KFintech) using their PAN or application number. If allotted, shares are credited to the Demat account; otherwise, the blocked amount is refunded. The allotment status plays a crucial role in IPO investing, influencing listing day trading decisions.
