Some IPO websites also list other small issues for this week. We have included only the issues on the official NSE and BSE lists on 24 October 2026.
What about grey market premium (GMP)?
GMP is not included in this article. When we checked on 24 October 2026, GMP figures for these issues appeared only on IPO aggregator websites, not in a named news outlet we could cite. The grey market is unofficial and not regulated by SEBI or the exchanges, and its numbers can change quickly. GMP is not an indicator of listing gains and is not advice.
Be careful with anyone who sends IPO "tips" or GMP-based calls over WhatsApp or Telegram. Our guide on how to check whether advice is SEBI-registered shows how to check who is behind such messages.
Before you apply: a few basics
You apply through ASBA (net banking) or UPI, usually inside your broker's app. You need a demat account to receive any shares that are allotted. If you are still choosing an account, our comparison of SEBI-registered stock brokers in India explains how to check a broker's registration and what it charges.
The UPI mandate has to be accepted by 5:00 pm on the last day of bidding, as each NSE issue page states.
Read the RHP's "Risk Factors" and "Objects of the Offer" sections. They tell you what the company does with the money and what could go wrong.
An IPO is equity. If you also trade MCX commodity futures, note that this is a separate segment. Our commodity brokers comparison covers that side.
Other issues coming up later are tracked in our upcoming IPOs watchlist for 2026.
FAQ
1. Which mainboard IPOs open between 26 and 30 October 2026?
Four: EAAA India Alternatives (26 to 28 October), BLS Polymers (27 to 29 October), SFC Environmental Technologies (27 to 29 October) and M. K. Sons Fine Jewels (28 to 30 October). All four plan to list on NSE and BSE.
2. What is the difference between a mainboard IPO and an SME IPO?
A mainboard IPO lists on the main NSE and BSE markets. An SME IPO lists on an SME platform such as BSE SME or NSE Emerge. SME issues are usually smaller and have much bigger minimum bids. This week the minimum SME bid is 2,400 shares for Core4 Engineers and 1,200 shares for Wiscon Industries.
3. When will these IPOs list?
According to the RHP timetables, EAAA India Alternatives is due to list on or about 2 November, BLS Polymers and SFC Environmental Technologies on or about 3 November, and M. K. Sons Fine Jewels on or about 4 November 2026. On BSE SME, Core4 Engineers is due on or before 30 October and Wiscon Industries on or before 3 November. These dates can change.
4. Does this article include the grey market premium (GMP)?
No. On 24 October 2026 we did not find GMP for these issues reported by a named news outlet that we could cite. GMP is unofficial and not regulated, it can change quickly, and it is not an indicator of listing gains or advice.
