There is a particular kind of overwhelm that only shows up during a busy IPO week. You open your broker app expecting to check on one issue, and instead you are staring at ten of them, each with its own price band, its own grey market premium, its own countdown timer. This is exactly what happened this week, when ten IPOs were open for subscription on the same day, together looking to raise more than Rs. 7,288 crore, reportedly the busiest single day the primary market has seen in three decades.

The honest truth is that most retail investors do not have a clean process for choosing between this many options at once. They end up either applying for everything with the highest grey market premium, or freezing entirely and missing the window. Neither is a good strategy. So let us build an actual framework, using this exact week as the working example.

What Actually Opened This Week

Six mainboard IPOs opened fresh for subscription, alongside four others already in their second or third day of bidding, plus a handful of SME issues layered on top. Rentomojo, the furniture and appliance rental platform, led the pack with a Rs. 1,256 crore issue split between a fresh issue and a larger offer for sale. Manipal Payment and Identity Solutions came in much smaller at Rs. 320 crore, aimed at funding capacity expansion in card issuance and identity solutions. Steamhouse India, an industrial equipment player, opened a Rs. 414 crore issue after already pulling in Rs. 124 crore from anchor investors. Asset Reconstruction Company brought its stressed-asset resolution business to market, while LCC Projects and Karamtara Engineering rounded out the day's fresh listings.

Layered on top of these were issues already mid-bidding, Pranav Constructions on its final day, Glass Wall Systems and Kanohar Electricals on day two, and Prasol Chemicals also on day two after a comparatively lukewarm opening. If you want a sense of how quickly this kind of primary market pipeline can build, our earlier piece on a Rs. 7,681 crore IPO week covered a similarly stacked stretch just weeks ago, and the pattern of bunching is becoming a genuine feature of this IPO cycle rather than an exception, something we also touched on when covering the current pipeline of India's biggest upcoming IPOs for the year ahead.

The Ten, At a Glance

IPO	Sector	GMP Signal
Pranav Constructions	Construction	Around 35%
Kanohar Electricals	Electricals	Around 35%
Rentomojo	Rental & Subscription Services	Around 32%
Glass Wall Systems	Building Materials	Around 31%
LCC Projects	Infrastructure Projects	Around 27%
Karamtara Engineering	Engineering	Around 27%
Steamhouse India	Industrial Equipment	Around 22%
Asset Reconstruction Co.	Stressed Asset Resolution	Around 22%
Manipal Payment & Identity	Payments & Identity Tech	Around 11%
Prasol Chemicals	Specialty Chemicals	Around 4%

A Simple Framework for Choosing Between Them

Grey market premium is the first number everyone looks at, and it is genuinely useful, but only as a starting filter, not a final answer. Notice how wide the spread is above, from 35% down to 4%, within a single day's set of issues. That gap alone tells you the market is already pricing in real differences in perceived quality, growth story, and risk. The mistake is treating GMP as a prediction rather than a sentiment snapshot; our coverage of the Leap India listing where shares fell 12% below issue price despite a reasonably positive GMP beforehand is a useful reminder that grey market signals can and do get it wrong.

Once GMP has narrowed your list, look at what the money is actually funding. Rentomojo's issue is a mix of a modest fresh issue and a much larger offer for sale, meaning most of the money is going to existing investors cashing out rather than the company itself, a structure we explained in detail in our piece on the LIC OFS and what it means to bid or wait. Compare that with Manipal Payment and Identity Solutions, where the fresh issue money is earmarked specifically for capacity expansion, a cleaner growth story even though its GMP sits far lower.

Sector context matters more than people give it credit for. A muted response like Prasol Chemicals is seeing is not automatically a red flag, some sectors simply carry less retail excitement even when the underlying business is sound; our earlier piece on a Horizon Industrial Parks IPO with a similarly muted GMP made a similar point, that unglamorous sectors often get judged unfairly against flashier consumer names in the same bidding window.

Company specific risk flags deserve their own separate check. Rentomojo's filing includes a co-founder's pending legal petition, a detail easy to miss in the excitement of a 32% GMP but genuinely worth reading about before applying. Similarly, Manipal Payment's promoter stake dropping to 53% post-issue is a dilution level worth noting, even if it is not disqualifying on its own.

Why So Many IPOs Land on the Same Day Anyway

This bunching is not really a coincidence. Companies and their bankers often try to launch when broader market sentiment is calm enough to support demand, and SEBI approval windows tend to clear in batches rather than evenly through the year. When ten issues land together, it usually means ten different companies all independently judged this to be a reasonable window, which is itself a small signal, though not one you should over-read given how differently each of them is being received by the grey market.

What This Means for Your Application Strategy

With this many options open at once, the temptation is to spread thin, applying for a little bit of everything. That is rarely the right instinct. It is more useful to rank your shortlist by conviction, using GMP as a first filter, use-of-proceeds as a second, and specific risk flags as a final check, then commit meaningfully to two or three names rather than diluting your allocation odds across all ten. Position sizing discipline matters here just as much as it does in any other trade, something our piece on the 3-5-7 rule for money management covers well, and a busy IPO week is precisely the kind of moment where that discipline tends to slip because everything feels urgent at once.

It is also worth remembering that listing day gains and long term holding are two entirely different decisions. Our coverage of the Manipal Health IPO and whether it was worth holding long term is a good example of how a strong listing pop and a genuinely good multi year investment do not always overlap, and a stacked IPO week is exactly when that distinction gets lost in the noise.

Frequently Asked Questions (FAQ)

1. Is it safe to apply for the IPO with the highest GMP?

Not necessarily. GMP reflects current sentiment, not a guaranteed outcome, and several IPOs with strong GMP have still listed below their issue price.

2. How many IPOs should I apply for in a busy week like this?

It is generally better to shortlist two or three names based on conviction rather than applying thinly across every available issue, since spreading too widely reduces meaningful allocation in any single one.

3. Why did some IPOs this week have a much lower GMP than others?

GMP differences often reflect sector sentiment, use of issue proceeds, and company specific risk factors rather than the underlying business quality alone.

4. Does an offer for sale structure make an IPO less attractive?

Not automatically, but it does mean proceeds go to existing shareholders rather than funding company growth, which is worth factoring into your decision.

5. Why do so many IPOs open on the same day?

This usually happens because SEBI approvals tend to clear in batches and companies often time launches around periods of calmer broader market sentiment.
