Upcoming IPO Calendar: September 2026

The latest market listings corroborate most of this calendar and the announced price bands.

Important correction: the supplied IPO calendar image shows Kheria Autocomp closing on September 22. More recent market information from Economic Times and Moneycontrol lists the closing date as September 21, 2026, with allotment expected on September 22. Investors should therefore check the latest RHP/exchange notice before applying.

1. Hero Motors IPO

The IPO rush starts on September 16, 2026, with Hero Motors among the most prominent offerings.

Hero Motors IPO details

• Opening date: September 16, 2026

At the upper end of the band, one lot of 178 shares costs approximately ₹14,952.

The allotment is expected on September 21, followed by refunds/share credit on September 22 and listing on September 23.

Hero Motors could attract attention from investors looking for exposure to India's automotive and engineering ecosystem, but investors should still examine the company's financial performance, valuation, debt and issue objectives before subscribing.

2. Jindal Supreme India IPO

Another mainboard IPO opening September 16 is Jindal Supreme (India) Limited.

Jindal Supreme IPO details

• IPO date: September 16–18, 2026
• Price band: ₹88–₹93
• Lot size: 161 shares
• Minimum investment at upper band: ₹14,973
• Issue size: around ₹124.88 crore
• Allotment: September 21
• Listing: September 23

Jindal Supreme manufactures and supplies steel pipes and tubes for industrial and infrastructure applications.

The IPO therefore provides exposure to a business whose demand can be influenced by infrastructure investment, industrial capex and steel-market conditions.

3. SS Retail IPO

SS Retail Limited will also open for subscription on September 16.

SS Retail IPO details

• Opening: September 16, 2026
• Closing: September 18, 2026

4. NSE IPO: The Biggest IPO to Watch

The National Stock Exchange of India IPO is easily the headline IPO of this calendar.

NSE IPO dates and price

Open: September 17, 2026
Close: September 21, 2026
Price band: ₹1,700–₹1,785
Lot size: 8 shares
Minimum investment at upper band: ₹14,280
Expected listing: September 24, 2026

The final offer consists of an offer for sale of roughly 126.4 million shares, and reports put the overall issue at approximately ₹22,562–₹22,569 crore around the upper end of the price band. Since it is an OFS, the proceeds go to selling shareholders rather than directly to NSE.

Why is the NSE IPO important?

NSE occupies a central position in India's capital-market infrastructure. Consequently, the IPO is not merely another corporate listing; it gives public-market investors an opportunity to own equity in one of the institutions at the core of India's securities ecosystem.

Because of its size and profile, the NSE IPO is likely to dominate investor attention during the September 17–21 bidding window.

5. Sonaselection India IPO

• Listing: September 24

SpectraA is an engineering-led company working on greenfield and brownfield projects across sectors including breweries, distilleries, food and beverages, FMCG and pharmaceuticals.

SME IPOs can carry greater liquidity and volatility risks than larger mainboard offerings, so investors should evaluate these factors separately rather than comparing them solely on potential listing gains.

Big IPOs Still Waiting for Dates

September's scheduled issues are only part of India's broader IPO pipeline.

Jio Platforms IPO

Jio Platforms filed its DRHP on June 19, 2026 for a proposed fresh issue of up to 27 crore equity shares. However, the final public bidding dates and price band have yet to be announced.

Zepto IPO

Zepto filed an updated draft red herring prospectus in June 2026. Its final issue dates have not yet been announced.

PhonePe IPO

PhonePe is also progressing through the IPO process, with an updated DRHP-I appearing in January 2026 offer-document records. The final opening date remains awaited.

boAt / Imagine Marketing IPO

Imagine Marketing, the parent company behind boAt, has also filed updated IPO documents, but a final bidding schedule has not yet been announced.

Hero FinCorp also continues to feature in IPO documentation, although its final issue dates are yet to be confirmed.

Mainboard vs SME IPO: What's the Difference?

The September IPO calendar contains both categories.

Mainboard IPOs generally involve larger companies, greater issue sizes and shares listed on the main exchanges.

SME IPOs are designed for small and medium-sized companies and can have higher minimum application amounts, lower trading liquidity and additional volatility.

For example, NSE, Hero Motors and SS Retail are mainboard offerings, while SpectraA Technology, Kheria Autocomp, Axiom Gas Engineering and Robokidz are SME issues.

Investors should therefore not judge the two categories using identical risk assumptions.

---

What Should Investors Check Before Applying for an IPO?

An IPO's popularity or grey-market premium should not be the sole basis for an investment decision. Investors should examine:

• revenue and profit growth;
• cash flow;
• debt and working-capital requirements;
• valuation compared with listed peers;
• fresh issue versus offer for sale;
• use of IPO proceeds;
• promoter holdings;
• customer or supplier concentration;
• sector outlook;
• risks disclosed in the RHP/DRHP; and
• institutional and retail subscription trends.

A high GMP can change rapidly and is neither regulated exchange pricing nor a guarantee of listing gains.

September 2026 Could Be a Major Month for India's IPO Market

September 2026 is shaping up to be a significant period for India's primary markets.

The NSE IPO is likely to capture the most attention due to its size and the exchange's position in India's financial system, while Hero Motors, SS Retail, Jindal Supreme and Sonaselection India provide investors with exposure to very different industries.

At the same time, a busy SME calendar means investors will have choices across engineering, auto components, industrial equipment, education technology and printing.

Beyond these offerings, the IPO pipeline remains strong, with Jio Platforms, PhonePe, Zepto, Hero FinCorp and boAt/Imagine Marketing among the major names investors are watching.

All IPO dates, price bands and issue details should be checked against the latest RHP, stock-exchange announcement or SEBI filing before making an investment decision.
