Upcoming IPO in September 2026.
Indian primary markets are buzzing again this month, and investors are actively searching for details on the Upcoming IPO in September 2026. From mainboard heavyweights to fast-moving SME issues, September has brought a fresh wave of listings across sectors like fintech, engineering, chemicals, and payments infrastructure. If you are planning to apply for any of these offers, knowing the price band, issue size, and current grey market premium (GMP) can help you make a more informed decision before the subscription window closes.
In this article, we break down the complete Upcoming IPO in September 2026 calendar, share the latest GMP trends, and answer the most common questions investors are asking right now.
Mainboard IPOs Opening This Week
Several mainboard companies have hit the market together, making this one of the busiest weeks of the year. Prasol Chemicals and Glass Wall Systems opened their subscription windows on September 8, while Rentomojo, Karamtara Engineering, Asset Reconstruction Company of India (ARCIL), and Manipal Payment followed on September 9. Kanohar Electricals has also drawn strong attention, largely because of its unusually high grey market activity compared to peers listing in the same window.
Rentomojo stands out as the largest issue this cycle, with an issue size of over ₹1,255 crore and a price band placed between ₹384 and ₹404 per share. Investors tracking rental-tech and subscription-based business models are watching this listing closely.

Why GMP Alone Can’t Determine a Good IPO Investment
Many first-time applicants rely heavily on GMP while ignoring fundamentals like subscription numbers, anchor investor participation, and the company’s financial health. A high GMP can fade quickly if institutional demand weakens closer to listing day, so treating the Upcoming IPO in September 2026 GMP figures as one data point rather than the final word is a safer approach.
How to Monitor These IPOs Before You Invest
Before applying to any Upcoming IPO in September 2026, check the red herring prospectus (RHP), compare the company against listed peers, and review subscription data on the final bidding day. QIB and HNI subscription trends often reveal more about listing-day demand than GMP alone.
