Some weeks in the market calendar are busy. This one is genuinely overloaded. Between September 22 and 26, retail investors have to track a mega stock exchange listing, six or more fresh mainboard IPOs across completely different sectors, a steady stream of SME issues, and a heavy stretch of dividend ex-dates landing almost every single day. If you only have time to check one calendar this week, this is the one to bookmark.

The Headline Event: NSE Finally Lists

This is the story everyone is actually watching. NSE's own IPO, after months of build-up, is set to list on September 24, right in the middle of this week. We have tracked this story closely from the moment its issue opened, through our coverage of NSE IPO's final days to apply, GMP, and allotment details, and our broader guide on everything retail investors need to know about the NSE IPO. If you applied and are waiting on allotment, this week is when you finally find out where you stand.

The Mainboard IPO Lineup

Alongside NSE, at least six other mainboard companies are opening for subscription this week, spanning a genuinely wide mix of sectors.

Swastika Infra is worth a closer look if you're drawn to infrastructure names. The company had 18 ongoing power transmission and distribution projects and an unexecuted order book of around Rs. 916 crore as of July 2026, giving it reasonable revenue visibility for a smaller issue. A-One Steels' price band sits between Rs. 385 and Rs. 405, with a lot size of 37 shares working out to roughly Rs. 14,985 at the upper end, similar to the minimum ticket size on both Varmora Granito and Swastika Infra, a pattern worth noticing if you're planning to apply to more than one of these in the same week.

Hero Motors and the Broader Listing Pipeline

Hero Motors, which we covered in our piece on the IPO flood featuring Hero Motors, Jindal Supreme and Glass Wall, is also part of this same cluster of activity, and its listing is expected to land around this same window. Between NSE's mega listing and these smaller mainboard debuts, this is genuinely one of those weeks where checking allotment status across multiple applications at once becomes its own small task.

SME Issues Add to the Volume

On top of the mainboard names, the SME segment continues its usual heavy pace through this same stretch, following the same pattern we've tracked in recent weeks, including our coverage of Kanohar Electricals' GMP and subscription status. If you're specifically tracking SME opportunities, it's worth checking a live IPO tracker for the most current day-by-day list, since SME issue dates tend to shift more frequently than mainboard ones.

The Dividend Ex-Date Stretch

Alongside all this IPO activity, September is historically one of the heaviest months for dividend ex-dates, since many companies with July-August board meetings finalise record dates that land in this exact window. It's common to see well over a hundred stocks going ex-dividend across NSE and BSE combined during a single busy week like this one, spread fairly evenly across all five trading days rather than bunched on one day. If dividend income is part of your strategy, our piece on the best dividend yield stocks in India for 2026 is a good starting point, and it's worth checking NSE and BSE's live corporate action calendars directly for the exact list this week, since individual ex-dates do get revised close to the actual date.

How to Actually Navigate a Week Like This

With this much happening at once, the temptation is to apply to everything and sort it out later. That rarely works well in practice. We covered this exact dilemma in our piece on how to choose when 10 IPOs open on the same day, and the core advice holds here too, pick two or three issues that genuinely fit your risk appetite and sector interest, rather than spreading thin cheque amounts across every single name on the calendar.

Before applying to any of these, it's worth understanding how much weight to actually give the grey market premium. Our piece on whether you can trust grey market premiums is a useful reality check, since GMP tends to be far noisier for smaller, less-covered issues like several of the ones opening this week than it is for a name as widely tracked as NSE. And once you've applied, knowing how to actually read your subscription numbers matters just as much, something we detailed in our guide on how to read Day 1 and Day 2 subscription numbers. A slow first day doesn't always mean a weak issue, retail and institutional demand often show up on very different days within the same subscription window.

This is also not the first time this many issues have landed together. Our earlier coverage of a Rs. 7,681 crore IPO week showed a similar pattern, strong overall retail interest, but genuinely uneven outcomes across individual names once they actually listed. That's worth keeping in mind before assuming every issue this week will perform the same way just because the calendar looks equally busy for all of them.
