India's primary market could see a major surge in activity this September, with around 25 companies reportedly preparing to launch their initial public offerings (IPOs).

According to market estimates, companies could collectively raise around ₹20,000-25,000 crore during the month. A key reason behind the expected rush is the approaching deadline for several companies whose SEBI approvals are set to expire.

With market sentiment improving after a relatively cautious first half of the year, several issuers appear keen to take advantage of the current fundraising environment.

Around 25 Companies in the IPO Queue

Bankers say nearly 25 companies are currently lined up for potential IPO launches in September. The list includes both large businesses and mid-sized companies, with several proposed issues expected to raise more than ₹500 crore.

According to Sonia Dasgupta, MD and CEO of Investment Banking at JM Financial, the September pipeline indicates that companies have become more confident about accessing the capital markets after taking a cautious approach earlier this year.

Recent successful listings and improving investor sentiment have also encouraged companies to move ahead with their fundraising plans.

Major IPOs Waiting to Hit the Market

Several companies with existing SEBI approvals could potentially launch their issues before the September 30 deadline.

Estimated figures are based on the cited Prime Database data and may change when companies announce their final IPO structures.

Why September Could Be So Busy

The upcoming rush is closely linked to the validity period of SEBI's observations for several companies.

Typically, companies are required to launch their public issues within the prescribed validity period after receiving SEBI's observations. However, market conditions prompted the regulator to provide a one-time extension for certain approvals.

Companies whose approval periods were due to expire between April 1 and September 30, 2026, were reportedly given additional time until September 30, 2026.

This has created a relatively concentrated pipeline of companies attempting to complete their IPOs before the extended deadline.

SEBI Had Extended the Approval Window

SEBI's decision came amid concerns about geopolitical uncertainty and heightened market volatility, which had caused some companies to delay their fundraising plans.

The extension gave issuers additional breathing room to wait for more favourable market conditions rather than rushing into a public offering during a period of excessive volatility.

However, that additional window is now approaching its end.

According to data cited from Prime Database, 35 of the 161 companies with valid IPO approvals had approvals scheduled to expire on September 30, 2026.

What Happens If Companies Miss the Deadline?

Companies that fail to launch their IPOs before the applicable approval expires could face additional regulatory hurdles.

In such a situation, they may have to seek fresh regulatory clearance before proceeding with their public offering, potentially delaying their fundraising plans further.

This is one of the reasons why September could witness a significant concentration of IPO activity.

Investor Sentiment Has Improved

The expected IPO rush also reflects a change in market sentiment.

After a relatively subdued first half of the year, companies are now looking to capitalise on improved investor appetite and strong performances from some recent listings.

For issuers, a favourable market environment can provide an opportunity to raise capital at attractive valuations. For investors, however, a crowded IPO calendar means there could be many opportunities to evaluate at the same time.

IPO Boom Does Not Mean Every Issue Is a Good Investment

A large number of IPOs entering the market does not automatically mean that every offering will deliver strong returns.

Investors should examine factors such as the company's revenue growth, profitability, debt levels, valuation, use of IPO proceeds, promoter holdings and industry outlook before subscribing.

The September IPO pipeline could make the month an exciting one for India's primary market, but investors should assess each issue individually rather than making decisions based solely on the overall IPO momentum.
