Nine IPOs open between August 24 and August 31, 2026 — seven on the mainboard and two SME issues — while two of the biggest names of the current cycle close their books. Grey market premiums across the incoming batch range from flat to +68%, and the spread tells you more than any single number does. Here is the full week, what the GMP is actually signalling, and how to think about a calendar this crowded.

What the grey market is signalling
Ranked by GMP, the incoming batch looks like this: Kwick Forensic +68%, Lumino Industries +59%, Hy-Tech Engineers +57%, Symbiotec Pharmalab +40%, Sumax Engineering +32%, Skyways Air Services +24%, Madhur Knit Crafts +9%, Annu Projects +5%, and ABH Healthcare flat at zero.
That is an unusually wide spread for a single week, and it is worth reading carefully rather than simply going down the list from the top.
The highest GMP has the thinnest sourcing
We track how many independent grey market sources contribute to each reading, because a premium confirmed across multiple desks is a stronger signal than one quoted by a single operator.
Kwick Forensic Solutions leads the week at +68% — but that reading currently comes from a single source. Sumax Engineering at +32% is also single-sourced, as are both SME issues.
By contrast, Lumino Industries (+59%), Hy-Tech Engineers (+57%), Symbiotec Pharmalab (+40%), Skyways Air Services (+24%) and Annu Projects (+5%) all carry two-source consensus readings. Those are the numbers we would weight more heavily.
This is not a claim that Kwick's premium is wrong. It is a reminder that a single-source GMP has more room to move — in either direction — than a consensus one, and the headline number alone does not tell you which you are looking at.
Hy-Tech is the only opener with live subscription data
Hy-Tech Engineers is already showing 5.20x subscription, which is a genuine early demand signal rather than a grey market opinion. Subscription is verifiable exchange data; GMP is not. When the two agree — as they do here, with a +57% two-source premium — the case is materially stronger than GMP alone.
ABH Healthcare is the counter-example: at 0.31x subscribed with a flat GMP, both signals are pointing the same unenthusiastic direction.
The two closing this week deserve attention
Tempsens Instruments closes on August 24 at 134.76x subscribed with a +108% grey market premium — the strongest combination of the entire cycle. Augmont Enterprises closes August 25 at 12.04x with a +47% premium on a ₹750–₹788 band.
Both are past the point where a new applicant has much room to act, but they matter for a different reason: they set the sentiment backdrop the incoming batch opens into. A market that has just absorbed a 134x subscription is a market with less uncommitted retail capital available for the nine IPOs opening behind it.
What our listing data says about weeks like this
We track every IPO through to its actual Day 1 listing price. Across the 81 listings where we now have confirmed outcomes:
- 59 of 81 listed at a premium — a 73% positive rate
- Average listing gain was +19.1%, but the median was +10.1%
- Mainboard issues: 83% positive, +17.4% average across 29 listings
- SME issues: 67% positive, +20.0% average across 52 listings
The gap between the average and the median is the most useful number here. A handful of exceptional outcomes pull the average upward, which means half of all IPOs we have tracked returned less than 10.1%. If you are budgeting expectations for this week, the median is the more honest anchor.
The mainboard-versus-SME split is equally relevant given two SME issues open on Monday. SME listings have delivered a higher average gain but a meaningfully lower success rate — more upside, more variance. With the SEBI minimum application for SME issues now at ₹2 lakh, that variance is being taken on at double the ticket size it used to require.
The full GMP-versus-actual comparison for every IPO we track is on our GMP performance tracker, updated as each one lists.
How to approach a crowded calendar
Nine issues in eight days creates an allocation problem, not just a selection problem. A few things worth holding in mind:
Your capital is finite; the calendar is not
Applying to everything spreads your funds thin and blocks capital across multiple issues simultaneously. Retail allotment in an oversubscribed IPO runs on a lottery at one lot per successful applicant, so scale does not improve your odds within a single issue — it only reduces what is available for the next one.
Crowding dilutes subscription
When several issues compete for the same retail pool in the same week, subscription figures across the group tend to be softer than the same companies would have seen in a quiet week. Do not read a modest subscription number in a crowded week the same way you would read it in isolation.
Staggered closes give you information
The August 24 openers close on the 27th; the August 27 openers close on the 31st. That means by the time Kwick and Lumino close, you will have seen final subscription data for Symbiotec, Hy-Tech, Skyways and both SME issues — and Tempsens will have already listed on August 28. Waiting costs you nothing and tells you a great deal.
Live subscription and GMP for every one of these is tracked on our upcoming IPO page, updated through the day.

Frequently Asked Questions
Which IPO has the highest GMP this week?
Among the issues opening between August 24 and 31, Kwick Forensic Solutions has the highest reading at +₹61 (+68%) on a ₹85–₹90 band. However, that figure currently comes from a single grey market source. Lumino Industries at +59% and Hy-Tech Engineers at +57% carry two-source consensus readings and are, on sourcing quality alone, firmer numbers. Tempsens Instruments is higher still at +108% but closes on August 24.
How many IPOs open this week?
Nine open between August 24 and August 31, 2026 — seven mainboard issues (Symbiotec Pharmalab, Hy-Tech Engineers, Skyways Air Services, Sumax Engineering, Annu Projects, Kwick Forensic Solutions and Lumino Industries) and two SME issues (ABH Healthcare and Madhur Knit Crafts). Two more, Tempsens Instruments and Augmont Enterprises, close during the same week.
Should I apply to all of them?
Applying to every issue spreads capital thin and blocks funds across multiple applications at once. Because retail allotment is decided by lottery at one lot per successful applicant, applying to more issues does not improve your odds within any single one. The staggered close dates this week mean you can see final subscription data for the earlier issues before committing to the later ones.
What does a single-source GMP mean?
It means the premium is being quoted by one grey market operator rather than confirmed across several. Grey market liquidity is thin and informal, so a single-source reading can move sharply in either direction and is a weaker signal than a consensus figure carrying the same headline number.
