IPO GMP, Live Subscription Status: How to Read Both as HD Fire Protect Opens (Oct 13, 2026)

HD Fire Protect’s ₹712-crore IPO opens for bids today, Tuesday, October 13, 2026, and all week two numbers will follow it around. The first is the grey market premium, or GMP, that tracking websites quote. The second is the live subscription status the exchanges publish. Looking at IPO GMP and live subscription status side by side helps, but only once you accept that they measure completely different things. Below we go through what each number is, where it comes from, how to read it and why the two can point in opposite directions, with HD Fire Protect and last month’s NSE IPO as worked examples.

IPO GMP and Live Subscription Status: The Short Answer

Subscription status is an official count. It shows how many shares investors have bid for in each category against the number reserved for that category. GMP is an unofficial price quote. It’s what informal dealers say they’d pay over the issue price for shares that aren’t listed on any exchange yet.

What Live Subscription Status Actually Measures

Subscription is just a ratio. UpcomingIPO’s explainer defines it as shares bid for divided by shares reserved. An issue subscribed 3 times has drawn bids for three times the stock on offer. It doesn’t measure money raised, and it isn’t a price.

Each investor category gets its own ratio, because shares are reserved in fixed blocks. For HD Fire Protect, the issue details on IPO Master give the split as not more than 50% of the net issue for qualified institutional buyers (QIBs), not less than 35% for retail investors and not less than 15% for non-institutional investors (NIIs). The NII block is split again into small NIIs, bidding between ₹2 lakh and ₹10 lakh, and big NIIs, bidding above ₹10 lakh. Retail investors can bid up to ₹2 lakh.

This is exactly why the headline number can fool you. An issue can look massively subscribed overall because institutions rushed in, while the retail book is barely covered. Or it can be the other way round. What decides your allotment odds is the row for the category you bid in.

Why the anchor book is left out

Anchor investors are big institutions that get their shares one working day before the public window opens. In larger issues, anchors can take up to 60% of the QIB portion. Since their shares are already settled, exchange subscription tables show the QIB category “ex-anchor” and leave the anchor portion out of total shares offered, as HDFC Sky’s NSE IPO data note shows.

HD Fire Protect wrapped up its anchor round on Monday, October 12. Livemint reported that the company raised ₹213.11 crore by allotting 78.64 lakh shares at ₹271 each, the top of the ₹258-271 price band. Domestic mutual funds took 56.52 lakh of those shares, or 71.88% of the anchor allocation, through 17 schemes. The entire issue is an offer for sale of 2.63 crore shares by the promoters, which means the company itself gets none of the money. When the exchanges start putting out subscription data today, those 78.64 lakh anchor shares won’t be in the denominator.

Where to watch it live

While an issue is open, the exchanges publish category-wise bid data. On the NSE IPO pages, open the issue’s own page to see bids by category. Treat these figures as provisional until the issue closes, since the exchanges reconcile bids afterwards. For a step-by-step walk through those tables on smaller issues, see our guide to SME IPO subscription status.

What GMP Is, and Why It Is So Slippery

The grey market is an informal, over-the-counter network where dealers trade IPO applications and allocations before listing. The Hindu BusinessLine describes it as a market SEBI doesn’t regulate the way it regulates the formal one, with no formal investor protection. GMP is just the rupee amount over the issue price implied by those off-exchange quotes. Price an IPO at ₹300, see grey quotes at ₹360, and the GMP is ₹60. The same piece warns that rumour or a tight group of dealers can push these prices around, particularly in issues with a small float, and that you have no SEBI-backed recourse if the other side doesn’t pay up.

We go deeper into the mechanics in what is GMP in IPO, with an example. What matters here is that GMP has no single official source. Every website reports its own take on informal quotes.

Subscription status counts bids that actually exist in the exchange book. GMP reports what someone outside the book says a share might be worth. Only one of them is a fact.

HD Fire Protect: two GMPs on the same evening

HD Fire Protect shows the problem nicely. On the evening of October 12, IPO Ji logged a GMP of ₹78 at 8:45 PM IST, which it worked out as 29% over the ₹271 upper band and an indicative listing price of ₹349. IPO Master, updated at 8:00 PM IST that same evening, had the GMP at ₹86, or 31.73% over the upper band, implying ₹357. That’s an ₹8 difference between two trackers inside an hour. And IPO Master’s own history shows the quote sitting at zero on October 6 before it climbed.

Put that in terms of one retail lot. A lot is 55 shares, which costs ₹14,905 at ₹271. A ₹78 premium suggests a paper gain of ₹4,290 on that lot; an ₹86 premium suggests ₹4,730. Neither is a promise. Both are snapshots of informal quotes that can shift within hours, and both sites call them unofficial.

The NSE IPO: Strong Subscription, Shrinking GMP

The National Stock Exchange’s own IPO last month is a good lesson in why you have to read these two numbers separately.

Subscription was strong. Angel One’s summary of exchange data shows the issue closing on September 21, 2026 at 5.71 times overall. The QIB (ex-anchor) portion was subscribed 12.68 times, NIIs 6.55 times and retail 1.39 times. In the retail book, bids came in for 6,13,05,464 shares against 4,41,01,125 reserved. Demand built up late, too: HDFC Sky’s data put the overall figure at 0.43 times on day one and 1.04 times on day two.

GMP, meanwhile, was sliding. ET Now reported that the unlisted premium peaked at ₹310 on September 5, fell to ₹192 by September 10 and ₹160 by September 15, and was at ₹43 the day before listing. That ₹43 pointed to a debut around ₹1,828 against the ₹1,785 issue price.

The listing came in lower still. The Times of India reported that NSE shares opened at ₹1,800 on BSE on September 24, a 0.84% premium to the issue price. They hit ₹1,878 and closed at ₹1,818, a first-day gain of 1.85% for IPO investors, on a day the Sensex lost 1.67%.

So here was an issue subscribed more than five times, with institutions bidding for over twelve times their quota, and it opened with a gain of under 1%. The GMP that had once hinted at a ₹310 premium per share overshot the actual opening premium of ₹15 by a mile. Heavy subscription told investors that allotment would be tough and that demand was genuine. It said nothing about how big the listing pop would be. On that, the early GMP was just wrong.

High subscription means it is hard to get shares. It does not mean the shares will list at a big premium. Those are two separate questions.

How to Use Each Number Without Getting Burned

Use subscription status for allotment odds and demand quality

• Read your own category. If you’re applying as a retail investor, the retail row matters more than the headline figure. The more times that row is covered, the lower your chance of getting any shares at all.
• Look at who’s bidding. A strong QIB (ex-anchor) number shows institutional demand over and above the anchor book.
• Wait for the last day. As the NSE example shows, day-one figures tend to be low. Judge demand on the closing number.

Treat GMP as gossip with a number attached

• Compare at least two trackers and check the time stamp. HD Fire Protect showed an ₹8 gap inside an hour.
• Watch the direction more than the level. When the premium keeps falling while subscription climbs, as it did with NSE, listing-day hopes are cooling off.
• Never apply just because of GMP. Look at the issue size, the use of proceeds (for HD Fire Protect, none of it goes to the company), the financials and the valuation first. Our upcoming IPO calendar for this week lists the other issues opening at the same time.
• Stay out of the grey market. No exchange stands behind the trade, and there’s no SEBI-backed recourse if a deal isn’t honoured.

Why SEBI Wants a Regulated Alternative

The regulator hasn’t hidden its discomfort with pre-listing grey market activity. In January 2025, then SEBI chairperson Madhabi Puri Buch said SEBI was actively looking at “when-listed” trading, The Indian Express reported. She pointed out that listing happens at T+3, three working days after the issue closes, and that plenty of grey market trading goes on even in those three days. Under the T+3 rule, allotment happens on T+1.

At the FICCI Capital Market Conference 2025, SEBI chairman Tuhin Kanta Pandey said a regulated venue for pre-IPO companies, subject to disclosures, was being considered on a pilot basis, according to the Times of India, which cited PTI. Until something like that covers the window between allotment and listing, GMP numbers will keep coming from informal quotes. That alone is a good reason not to lean on them much. SEBI’s own investor notices are on the SEBI website.

HD Fire Protect: Dates to Track This Week

• Bidding: October 13 to October 15, 2026, price band ₹258-271

• Valuation: about ₹4,750 crore at the top of the band, per Livemint

Over the next three days, keep an eye on the retail and QIB (ex-anchor) rows on the exchange bid pages, and read any GMP you come across as a mood reading rather than a forecast. Once bidding closes, our guide on how to check IPO allotment on NSE and BSE takes you through the result pages.
