Reviewed November 2026. Investors looking for upcoming mainboard IPOs should distinguish a proposed stock-market listing from an officially announced public issue. Draft offer documents, price-band notices and issue timetables are published at different stages. This guide explains where to check confirmed details and how to compare opportunities without relying on speculative dates.
Where to find an upcoming mainboard IPO list
Use NSE upcoming IPO information, NSE issue advertisements, BSE and SEBI public filings to confirm what is officially available. For company-by-company summaries, our WatchIPO GMP tracker aims to present currently relevant issues, with source and observation times when available. An estimated issue month on a news site should not be treated as a booking date.
A draft filing is not an open IPO
An issuer may submit a Draft Red Herring Prospectus (DRHP), an updated draft or a confidential filing before any public bid period begins. Subsequent documents and price-band announcements establish more details. The final offer timetable and company disclosures, rather than an early analyst prediction, should determine when you can apply.
Five checks before considering a mainboard IPO
- Opening and closing dates: confirm the company, stock exchange and official issue schedule.
- Price band and lot: verify the shares in one retail application lot and the minimum required amount.
- Prospectus risks: review customer concentration, debt, cash flows, legal risks and the use of proceeds.
- Offer structure: distinguish a fresh issue that funds the issuer from an offer for sale by shareholders.
- Valuation: compare earnings, growth and balance-sheet quality with comparable listed businesses.
Price band, cut-off price and IPO application amount
The minimum retail bid amount depends on the specified lot size and the applicable issue price. For example, 20 shares at a hypothetical upper price of ₹250 cost ₹5,000; this is an illustration rather than a live IPO. Broker and bank interfaces may present a cut-off choice for eligible retail applicants, while the official issue rules govern deadlines and accepted payments. Read the RHP before submitting a bid.
What is ASBA and a UPI IPO mandate?
Application Supported by Blocked Amount (ASBA) keeps the application amount blocked in the bank account until the applicable allotment or release process. Eligible applicants may use approved UPI-based methods through supported intermediaries. Complete the bank or UPI mandate on time; a submitted broker order alone may not complete an application. Use only the authentic broker or bank interface.
IPO subscription and GMP are different signals
Subscription statistics describe bids made under categories such as qualified institutional, non-institutional and retail investors. Grey market premium (GMP) is an unofficial quote outside the exchange order book. Neither a high subscription multiple nor a positive GMP guarantees listing gains, and different sources can report different GMP prices. Always check the time and source of a reported premium.
IPO allotment, listing and refund timeline
After bidding closes, the basis of allotment is determined according to the applicable issue rules. The registrar handles issue-specific allotment records; successful applicants receive allotted shares in their demat account, and other applicants generally have blocked funds released. Our Link Intime/MUFG allotment guide explains how to check one major registrar, but other issues may use KFin Technologies or Bigshare.
How to use this article when names and dates change
This is an evergreen explainer, not a fixed list of IPOs claimed to be open right now. For each newly announced company, use its individual article and check for a source-backed last-updated time. Revisit the official exchange notice if the issuer changes the timeline, lot or price band. For the broader list, use the regularly maintained IPO dashboard rather than relying on old snapshots.
