The Indian stock market offers a big platform for existing companies to raise funds. These large companies make their debut in the market under the name of a Mainboard IPO. It enables them to gather capital from a large number of investors from throughout the country.

These funds are used by large corporations to grow or for repayment of debts. Investors wait for such opportunities to invest in known and stable brands. This guide will teach you about the primary market listings in India.

What is Mainboard IPO?

A Mainboard IPO is a first time for a large and established company to sell its shares to the general public. These companies are listed on the main exchange of the National Stock Exchange or the Bombay Stock Exchange. They should possess good financial experience and must have paid-up capital of at least 10 crore rupees. Also, the operating profits of ₹15 crore over 3 of the last 5 years are necessary.

This kind of public issue is very popular in attracting a large number of participants, such as big banks and foreign investors. These listings have very strict rules to protect the interests of small retail investors. Companies are required to adhere to all the rules laid down by the Securities and Exchange Board of India.

Rules to Apply for Mainboard IPO

Mainboard IPOs are accessible to almost everyone with a basic investment budget. The rules are made as easy as possible to ensure maximum participation from common people. These issues are highly regulated to ensure a fair chance for all applicants.

Retail Investment Cap

The retail investor can make an application for a maximum of two lakh rupees in a single IPO. For those who want to invest more, they will have to apply under the Non-Institutional Investor (NII) category. This rule ensures that big investors do not crowd out small retail participants.

Single PAN Application

You are allowed to submit only one application per PAN card for a specific IPO. If more than one application is found in a system with the same PAN, all applications will be rejected. This will help to keep the allotment process fair and follow a lottery system when demand is high.

Steps to Apply for Mainboard  IPO

The IPO application process is extremely fast and takes only a few minutes. The UPI method is the most common way for most investors to invest due to its speed and convenience. If you prefer a direct bank method, you can use the net banking ASBA facility. To apply for the Mainboard IPO, you can follow the following steps:

StepDescription

To access the bidding form, click on the “Apply” button next to the company name. You can check the mainboard IPO GMP to know the unofficial demand.
Place Your BidIf you want to improve your chances of getting an allotment, select the “Cut-off Price”. This ensures that your bid is valid regardless of the final price decided by the company. Now, you will need to enter the number of lots and your UPI handle to continue.
Verify and block fundsWhen the mandate request message appears on your phone authorise the transaction immediately. Your bank will send you a confirmation message once the funds are successfully blocked. After the closing of the window, you can check the status of your application on the registrar’s website.

Steps to Launch a Mainboard IPO

The process of going public on the main board is a lengthy and detailed process. It takes months to prepare and several approvals from the market regulators. Each step ensures the company gives correct information to the public.

StepDescription
Appointment of Lead ManagersThe company first appoints professional experts known as Book Running Lead Managers to handle the issue. These experts manage the legal aspect and help decide the value of the shares. They act as the main point of contact between the company and the regulators.
Filing the Draft ProspectusThe company prepares a massive document for the authorities, known as the Draft Red Herring Prospectus. This file contains the complete business plan and audited financial reports for the past few years. SEBI carefully reads this document and asks for changes if any information is missing.
Obtaining SEBI ObservationsThe market regulator issues an observation letter after checking the draft document thoroughly. This letter is a green light for the company to proceed with the public offer. The company then files the final version with the Registrar of Companies.
Marketing and RoadshowsThe company management sits down with large institutional investors and discusses their growth plan. This is a stage to help generate demand for shares prior to the actual bidding process. They also announce the price range in which investors can place their orders.
Bidding and AllotmentThe IPO opens for three to five days so that the public can apply for shares. The registrar then determines the final price after the window closes based on the bids received. The shares are then allotted to the successful applicants through a fair and computerized process.

Conclusion

Mainboard IPOs play a crucial role in the Indian financial system and in building wealth. They offer a transparent way for large companies to expand without sacrificing profits to the public. Before investing in these issues, investors need to closely analyse the performance of the company. Also, mainboard IPO GMP is an unofficial indicator of the demand and calculation of the probable listing price. IPO INDEX offers live updates with live and day-wise GMP status.

Frequently Asked Questions

What is Mainboard IPO?

A Mainboard IPO is for big, established companies that have a long track record. These companies are traded on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE). A company needs to have a high net worth and consistent profitability to qualify.

These public issues have a huge number of investors, including large global funds and retail individuals. The reporting standards are extremely strict because of the complete transparency for the public. The most famous household brands that you see on the stock market are listed via the Mainboard.

What is the minimum amount for a Mainboard IPO?

Retail investors usually need to spend around fifteen thousand rupees to apply for one lot. The exact amount depends on the price band and the number of shares in a single lot. If you have a larger budget for investment, you can apply for more lots. SEBI ensures that this entry barrier remains low, which will allow more people to participate in the market.

How can I apply for a Mainboard IPO online?

You may use your mobile trading app or the net banking portal of your bank. Most people prefer the ASBA method as it keeps the money in the individual’s account. All you have to do is choose the IPO name and enter your UPI ID or bank details. Then the exchange will submit a request to block the amount of the application in your account. You can check the official subscription status and unofficial mainboard IPO GMP updates to understand the demand.

What is the T+3 listing rule in 2026?

The T+3 rule means that the company must list shares within three working days. This timeline starts from the day the subscription window for the public closes. It speeds up the whole process and helps investors get their money back quickly if they do not get shares. This system has improved the efficiency of Indian stock market to a great extent.

Can I cancel my IPO bid after submitting?

Yes, retail investors can change or cancel their bid as long as the window is open. You must log in to the same platform where you originally placed your application. In the event of a cancellation, the money in your bank account will be unlocked and available for use. You cannot make any changes once the subscription period ends for the public.

How do I check if I received the shares?

The allotment status can be checked on the website of the registrar with the help of the PAN number. The registrar will show if you were received full allotment or not. You will also receive an email and a text message from the stock exchange about the status. If you get the shares, they will appear in your demat account before the listing day.

Why is my UPI mandate not showing for the IPO?

There may be a technical delay between the exchange and your UPI application. Make sure that you have written the correct UPI ID with no spelling errors or spaces. You should also find out whether or not your bank has UPI 2.0 functionality to block funds. If it doesn’t arrive within a few hours, reach out to your broker for assistance.

What if the IPO is oversubscribed?

When the demand for shares is significantly greater than the number of shares available, it is called oversubscription. In this case, the registrar uses a lottery system to distribute shares among retail investors. This ensures that every applicant has a fair chance of getting at least one lot. You might not get any shares if the demand is extremely high from the public.

What is the 'Cut-off Price' in an IPO application?

The cut-off price is the final price at which the company decides to issue its shares. By selecting this option, you agree to buy the shares at whatever final price is decided. This is the best strategy for retail investors to avoid their application getting rejected due to a low bid. Most successful allotments happen to those who choose the cut-off price option.

How to get a refund if I do not get allotment?

You do not need to worry about a manual refund because the money never leaves your account. The bank simply removes the block on the application amount after the allotment process is over. This money becomes available for your regular use within twenty-four hours of the status declaration. You should contact your bank branch if the amount remains blocked for more than a week.

What is the difference between a Fresh Issue and OFS?

A Fresh Issue means the company is creating new shares to raise fresh capital for its growth. An Offer for Sale or OFS means existing owners are selling their own shares to the public. In a fresh issue, the money goes to the company treasury for business operations. In an OFS, the money goes directly to the pockets of the selling shareholders.

Can I apply for an IPO from multiple accounts?

You can apply from different demat accounts only if they are registered under different PAN numbers. If you apply from multiple accounts using the same PAN, the exchange will reject all your applications. Many people apply in the names of their family members to increase their chances of allotment. Always ensure that the bank account and demat account belong to the same person.
