August 2026 kept India’s primary market busy with Manipal Health, Juniper Green Energy, and a wave of SME listings. September is shaping up to be even more crowded — ten confirmed mainboard IPOs are opening across three overlapping weeks, spanning construction, specialty chemicals, transformers, smart cards, irrigation EPC, stressed-asset reconstruction, furniture rental, solar structures, and industrial steam supply.
And that’s before the two names every investor is actually waiting on: Jio Platforms and the NSE itself. Neither has an official price band or date yet — but if either opens this month, September’s total fundraising could jump from a base case of roughly ₹20,000–25,000 crore to as much as ₹70,000 crore.

1. Pranav Constructions IPO
Mumbai’s redevelopment specialist goes public
Pranav Constructions IPO opens for subscription on September 7, 2026 and closes on September 9, 2026. The price band is set at ₹118 to ₹124 per share, with a lot size of 120 shares. Pranav Constructions IPO will list on the BSE and NSE with a tentative listing date of September 15, 2026.
| Detail | Information |
|---|---|
| Company | Pranav Constructions Limited |
| Business | Construction — residential, commercial & infrastructure redevelopment |
| Incorporated | 2003 |
| Open Date | September 7, 2026 |
| Close Date | September 9, 2026 |
| Price Band | ₹118 – ₹124 per share |
| Issue Size | ₹351.03 crore |
| Lot Size | 120 shares |
| Min Investment (Retail) | ₹14,880 |
| Retail Quota | 45% |
| Allotment Date | September 10, 2026 |
| Listing Date | September 15, 2026 |
| Registrar | Kfin Technologies Ltd. |
Why it matters: Pranav Constructions works across tendering, planning, construction, and post-handover for redevelopment projects in and around Mumbai — one of India’s tightest, highest-value real estate markets. The 45% retail quota is unusually generous versus the 35% standard, meaning individual investors get a bigger slice of this issue than most others opening this month.
2. Glass Wall Systems (India) IPO
Facade specialist with projects in the US and Australia
Glass Wall Systems (India) IPO opens on September 8, 2026 and closes on September 10, 2026. The price band is ₹172 to ₹182 per share, lot size 82 shares. Listing is tentatively fixed for September 16, 2026 on NSE and BSE.
| Detail | Information |
|---|---|
| Company | Glass Wall Systems (India) Limited |
| Business | Facade solutions & fenestration systems |
| Incorporated | 2010 |
| Open Date | September 8, 2026 |

| Price Band | ₹172 – ₹182 per share |
| Issue Size | ₹427.89 crore |
| Lot Size | 82 shares |

| Retail Quota | 35% |
| Allotment Date | September 11, 2026 |
| Listing Date | September 16, 2026 |
| Registrar | MUFG Intime India Pvt. Ltd. |
Why it matters: Glass Wall Systems has delivered more than 150 projects, including international work in the USA and Australia — a niche but export-relevant construction-materials play that isn’t a pure domestic real-estate bet.
3. Prasol Chemicals IPO
150+ products across acetone- and phosphorus-based chemicals
Prasol Chemicals IPO opens on September 8, 2026 and closes on September 10, 2026. Price band ₹643 to ₹676 per share, lot size 22 shares. Tentative listing date September 16, 2026.
| Detail | Information |
|---|---|
| Company | Prasol Chemicals Limited |
| Business | Specialty chemicals — performance, paints/inks, pharma, agrochemical & personal-care inputs |
| Manufacturing | Khopoli & Mahad (Maharashtra) |
| Open Date | September 8, 2026 |
| Close Date | September 10, 2026 |
| Price Band | ₹643 – ₹676 per share |
| Issue Size | ₹500 crore |
| Lot Size | 22 shares |
| Min Investment (Retail) | ₹14,872 |
| Retail Quota | 35% |
| Allotment Date | September 11, 2026 |
| Listing Date | September 16, 2026 |
| Registrar | Kfin Technologies Ltd. |
Why it matters: At ₹643–₹676, Prasol carries the highest per-share price band among this week’s mainboard issues — a small lot size of just 22 shares keeps the retail minimum in the standard ₹14,000–15,000 range despite the steep price.
4. Kanohar Electricals IPO ⭐ BIGGEST OF THE WEEK
One of only four RDSO-accredited 100 MVA transformer makers in India
Kanohar Electricals IPO opens on September 8, 2026 and closes on September 10, 2026. The price band is ₹601 to ₹632 per share, lot size 23 shares. Tentative listing date is September 16, 2026 on NSE and BSE.
| Detail | Information |
|---|---|
| Company | Kanohar Electricals Limited |
| Business | Transformers — power transmission, railways, renewables, distribution |
| Incorporated | 1972 |
| Open Date | September 8, 2026 |
| Close Date | September 10, 2026 |
| Price Band | ₹601 – ₹632 per share |
| Issue Size | ₹1,055.74 crore |
| Lot Size | 23 shares |
| Min Investment (Retail) | ₹14,536 |
| Retail Quota | 35% |
| Allotment Date | September 11, 2026 |
| Listing Date | September 16, 2026 |
| Registrar | MUFG Intime India Pvt. Ltd. |
Why it matters: At ₹1,055.74 crore, Kanohar is the largest issue opening in the September 8–10 window. The company is one of just four Indian manufacturers accredited by RDSO for 100 MVA 132 kV Scott transformers — a specialised niche tied directly to railway electrification and grid expansion. It also has the lowest minimum retail investment (₹14,536) among this week’s four IPOs.
5. Manipal Payment & Identity Solutions IPO
India’s largest banking and smart-card manufacturer
| Detail | Information |
|---|---|
| Company | Manipal Payment & Identity Solutions Limited (MPISL) |
| Business | Banking & smart cards — design, production, personalisation, delivery |
| Footprint | 10 manufacturing facilities, 19 units across 11 cities; UK, Europe, APAC, MEA presence |
| Open Date | September 9, 2026 |

| Lot Size | 44 shares |
| Min Investment (Retail) | ₹14,916 |
| Retail Quota | 10% (lowest of the week) |
| Allotment Date | September 15, 2026 |
| Listing Date | September 17, 2026 |
| Registrar | MUFG Intime India Pvt. Ltd. |
Why it matters: MPISL’s 10% retail quota is by far the lowest among this week’s issues — the bulk is reserved for institutional and HNI investors, a structure typical of larger, more capital-intensive manufacturing businesses.
6. LCC Projects IPO
Irrigation EPC with a 68-project order book across 11 states
| Detail | Information |
|---|---|
| Company | LCC Projects Limited |
| Business | EPC — dams, barrages, canals, pipe distribution, lift irrigation |
| Founded | 2017 |

| Retail Quota | 35% |
| Allotment Date | September 15, 2026 |
| Listing Date | September 17, 2026 |
| Registrar | Kfin Technologies Ltd. |
Why it matters: With an order book of 68 projects spanning 11 states, LCC is a pure infrastructure play tied to India’s ongoing irrigation and water-supply capex cycle.
7. Asset Reconstruction Company (India) IPO
A 100% offer-for-sale — proceeds go to sellers, not the company
| Detail | Information |
|---|---|
| Company | Asset Reconstruction Company (India) Limited (ARCIL) |
| Business | Acquiring & resolving stressed corporate, SME and retail loan assets |
| Issue Structure | 100% Offer for Sale — no fresh issue |
| Open Date | September 9, 2026 |
| Close Date | September 11, 2026 |
| Price Band | ₹132 – ₹139 per share |
| Issue Size | ₹732.97 crore |
| Lot Size | 107 shares |
| Min Investment (Retail) | ₹14,873 |
| Retail Quota | 35% |
| Allotment Date | September 15, 2026 |
| Listing Date | September 17, 2026 |
| Registrar | MUFG Intime India Pvt. Ltd. |
Why it matters: ARCIL’s entire ₹732.97 crore issue is an offer for sale — existing shareholders are exiting, and the company itself receives no fresh capital from the listing. Worth reading the RHP closely to understand who’s selling and why.
8. Rentomojo IPO 🛋️ LARGEST OF THE MONTH SO FAR
India’s largest furniture-and-appliance rental platform by subscribers
| Detail | Information |
|---|---|
| Company | Rentomojo Limited |
| Business | D2C furniture & appliance rental subscriptions |
| Scale | 2,53,825 live subscribers, 22–29 cities, 82 experience stores, 20 warehouses (as of FY26) |
| Issue Structure | Fresh issue ₹150 crore + OFS ₹1,105.57 crore |
| Open Date | September 9, 2026 |
| Close Date | September 11, 2026 |
| Price Band | ₹384 – ₹404 per share |
| Issue Size | ₹1,255.57 crore |
| Lot Size | 37 shares |
| Min Investment (Retail) | ₹14,948 |
| Retail Quota | 35% |
| GMP (Sep 4) | ₹30–₹45 (~8–11%) |
| Allotment Date | September 15, 2026 |
| Listing Date | September 17, 2026 |
| Registrar | Kfin Technologies Ltd. |
Why it matters: At ₹1,255.57 crore, Rentomojo is the single largest mainboard IPO confirmed for September so far. But only ₹150 crore of that — roughly 12% — is a fresh issue; the remaining ₹1,105.57 crore is OFS, meaning most proceeds go to existing shareholders rather than funding growth. Revenue grew 45% and profit after tax jumped 142% YoY, but at the upper band the post-issue P/E works out to roughly 40x, which is a demanding valuation for a rental business.
GMP signal: Grey-market trackers show Rentomojo’s premium moving between ₹30 and ₹45 in the days before close — mild-to-moderate positive sentiment, but GMP this early in the subscription window is a weak predictor. It tends to firm up (or unwind) on the final bidding day.
9. Karamtara Engineering IPO ☀️
Solar structures and transmission fittings exported to 50+ countries
| Detail | Information |
|---|---|
| Company | Karamtara Engineering Limited |
| Business | Solar structures, fasteners, transmission line fittings; own galvanizing & rolling mill |
| Operating since | 1996 |
| Open Date | September 9, 2026 |
| Close Date | September 11, 2026 |
| Price Band | ₹241 – ₹254 per share |
| Issue Size | ₹875 crore |
| Lot Size | 59 shares |
| Min Investment (Retail) | ₹14,986 |
| Retail Quota | 35% |
| Allotment Date | September 15, 2026 |
| Listing Date | September 17, 2026 |
| Registrar | MUFG Intime India Pvt. Ltd. |
Why it matters: Karamtara sits directly in India’s renewable-energy supply chain, with one of the largest solar-segment galvanizing and rolling-mill setups in the country and exports to more than 50 countries.
10. Steamhouse India IPO
Industrial steam and gas supply across a 45-km pipeline network
| Detail | Information |
|---|---|
| Company | Steamhouse India Limited |
| Business | Industrial utility — steam & gas supply via pipeline |
| Coverage | 45+ km pipeline network across Sachin, Vapi, Ankleshwar |
| Incorporated | 2015 |
| Open Date | September 9, 2026 |
| Close Date | September 11, 2026 |
| Price Band | To be announced |
| Issue Size | ₹414 crore |
| Retail Quota | 35% |
| Allotment Date | September 15, 2026 |
| Listing Date | September 17, 2026 |
| Registrar | Kfin Technologies Ltd. |
Why it matters: Steamhouse India is the smallest issue of the week by size and the only one still awaiting a confirmed price band as of publication — we’ll update this section the moment it’s announced.
Jio Platforms IPO 🚀
Could be India’s largest-ever IPO
| Detail | Information |
|---|---|
| DRHP Filed | June 19, 2026 |
| SEBI Status | Reportedly approved |
| Est. Issue Size | ~₹37,700 crore (~$3.8 billion) |
| Issue Type | Reported 100% Fresh Issue |
| Expected Window | August – October 2026 |
Why it matters: Jio remains the single biggest IPO story of 2026. Reports suggest SEBI approval has cleared, but no price band or exchange filing date has been made official — anything beyond “approved” is still speculation until the RHP lands.
NSE IPO 📈
The exchange that powers India’s markets
| Detail | Information |
|---|---|
| DRHP Filed | June 17, 2026 |
| Est. Issue Size | ~₹30,000 crore |
| Issue Type | Reportedly 100% OFS |
| Expected Window | Q3–Q4 2026 |
Why it matters: An NSE listing would be a landmark, decade-in-the-making event. If it launches alongside Jio in September, the two mega-issues alone could push the month’s total fundraising toward ₹70,000 crore — well above the ₹20,000–25,000 crore base case from confirmed IPOs.
Also Reportedly in the Pipeline
Beyond the ten confirmed IPOs and two mega-names above, several other companies are reportedly eyeing a September 2026 window, per industry trackers — though none have confirmed dates yet: Deepa Jewellers, Rays of Belief, Veegaland Developers, Elevate Campuses, Virupaksha Organics, Hero Motors, Manika Plastech, Parijat Industries, and Learnfluence Education. We’ll spin up dedicated coverage as each firms up its dates.
Note: This list is based on market reports, not official filings. Final launch dates, issue sizes and price bands may change or may not materialise this month at all.
