Open and Upcoming Mainboard IPOs

Open Mainboard IPOs are accepting bids now. Compare their closing dates, price bands, lot sizes, minimum investment, and subscription before applying.

For upcoming issues, check whether the dates are confirmed or expected. A company that has filed only a DRHP may not have announced its final price band or valuation. The guide on how to read a DRHP can help you examine the business, financials, and risk factors.

How to Compare Mainboard IPOs

AreaQuestions to ask
BusinessIs the revenue model understandable and reasonably diversified?
FinancialsAre revenue, profit, and operating cash flow moving consistently?
DebtHow much debt does the company have, and will the IPO reduce it?
Offer structureHow much is fresh issue and how much is OFS?
ValuationHow does the price compare with suitable listed peers?
RisksWhat do the offer documents disclose about litigation and key dependencies?
DemandHow are QIB, NII and retail investors responding?

Follow the IPO analysis framework to compare issues consistently.

How to Judge the Offer Structure

A fresh issue brings money into the company. An OFS allows existing shareholders to sell their shares. Neither structure is automatically good or bad, but the mix changes how the IPO may affect the business.

Check how fresh-issue proceeds will be used. Debt repayment, capacity expansion, or working capital may support future operations, but the benefit depends on execution. If most of the issue is an OFS, understand who is selling, how much ownership they retain, and why they are exiting.

Also check post-issue dilution. A growing company may use new capital productively, but issuing more shares changes the ownership and per-share economics for investors.

Which Mainboard IPO Should You Apply For?

Start with companies whose businesses you understand. Remove issues whose risks do not fit your financial position or investment horizon. Then compare financial quality, use of proceeds, and valuation.

High subscription cannot make an expensive or weak business attractive. If your objective is listing gains, demand and market conditions may matter more, but the outcome remains uncertain.

Mainboard IPO Decision Checklist

Before applying, answer these questions:

  • Can you explain how the company makes money?
  • Is growth supported by operating cash flow?
  • Is debt manageable before and after the issue?
  • Will the fresh proceeds strengthen the business?
  • Is the valuation reasonable compared with suitable peers?
  • Are promoter, governance or related-party risks acceptable?
  • Can you remain invested if the stock lists below the issue price?

If several answers are unclear, revisit the RHP or wait until the company has a public trading record. Missing an IPO does not prevent you from buying the stock after listing.

Mainboard IPO Allotment and Listing

After bidding closes, track final subscription, allotment, funds unblock, demat credit, and listing. For listed issues, compare the issue price with both the listing price and latest market price.

Listing gain measures the change from issue price to listing price. Current return measures the change from listing price to the latest price. These are different figures. If allotted shares are sold, refer to the IPO taxation guide for the applicable treatment.

How to Read Recent Mainboard IPO Performance

Compare IPOs over the same period. A high listing gain reflects the first market price, while long-term performance depends on results, execution, and the valuation investors continue to assign to the company.

Look at the issue price, listing price, listing-day close and current market price separately. This helps you avoid calling an IPO successful only because it opened strongly or unsuccessful only because it listed at a discount.

Mainboard IPOs vs SME IPOs

Mainboard and SME IPOs differ in listing framework, company scale, application amount, trading lot, and liquidity. Mainboard status does not make an IPO risk-free. Assess the individual company instead of relying on its category. The guide to types of IPOs explains the differences.
