Why Chasing IPO Listing Gains Might Be A Bad Idea

If you've spent five minutes in an Indian investing WhatsApp group during IPO season, you've seen the number. Grey Market Premium: an unofficial, SEBI-unregulated price at which IPO applications trade hands before the shares even list. It gets treated like a crystal ball. A high GMP and the group lights up. A GMP that drops and everyone gets nervous. We get asked about it constantly, usually with the same question underneath: "should I apply because the GMP looks strong?"

Four IPOs, right now, telling the same story

We're writing this in the third week of July 2026, and there happen to be four live examples sitting right in front of us. We're not picking these because they prove a point we already wanted to make; they're just what's in the market this month.

Kusumgar Limited priced its IPO at ₹419. In the days before listing, the grey market premium bounced around anywhere from ₹92 to ₹171, a swing of nearly 80 percent in the "predicted" gain, all before a single share had actually traded (IPO Watch, 2026). It finally settled near ₹154 the day before listing, suggesting roughly a 37 percent gain. The stock listed at ₹569, a 35.8 percent gain, close enough to that final number (Chittorgarh, 2026). Then it kept climbing to around ₹588 the next day, about 40.5 percent above the issue price (IPOJI, 2026). So if you'd applied based on the GMP two weeks earlier, you'd have been anywhere from wildly wrong to reasonably close, depending on which day you happened to check.

Alpine Texworld is the opposite story. Early GMP suggested a premium of around ₹10, about 9.5 percent (Sahi.com, 2026). By the day before listing, that had faded to ₹1 to ₹3, roughly a 2 to 3 percent premium (IndiaInfoline, 2026; IPOGrow, 2026). Subscription came in soft too, just 1.04 times overall (IndiaInfoline, 2026). The grey market got excited, then it didn't.

Laser Power & Infra went the other way again. GMP in the days before listing hovered around ₹34 to ₹37, implying roughly a 16 to 17 percent gain (Sahi.com, 2026; Multibagg, 2026). The stock actually listed at ₹250, a 16.8 percent gain, basically in line, and then it kept running to ₹288.66 the next day, nearly 35 percent above issue price (IPOJI, 2026). The grey market got the listing day roughly right and then missed the bigger move entirely, because GMP isn't designed to price in what happens after day one.

Caliber Mining & Logistics is still open as we write this. Its GMP has ranged from ₹15 to ₹116 within a single ten-day bidding window, and on the last day of bidding it sat at ₹80, down ₹6 from the quote before it (IPOJI, 2026; IPO Watch, 2026). We genuinely don't know where this one lands. Neither does the grey market, no matter how confident the number looks on a given afternoon.

Four IPOs. One faded hard, one roughly tracked its own final-day number, one wildly undershot a rally that followed listing, and one is still swinging by 50 percent within the space of a week and a half with no answer yet. That's not a cherry-picked bad month for GMP. That's what GMP does.

What GMP actually is, and isn't

Here's the part that doesn't get said enough: GMP isn't a forecast. It's a price. Specifically, it's the price at which a small, informal, unregulated group of traders is willing to buy or sell the right to an IPO allotment before it exists, usually based on subscription numbers, sentiment, and how loudly people are talking about the issue on a given day (Acumen Group, 2026). Every single source we pulled for this piece, including the trackers that publish GMP numbers daily, carries some version of the same disclaimer: unofficial, unregulated, can change overnight, not a reliable indicator of listing gains (Sahi.com; IPOJI; IPOGrow, 2026, among others). The people publishing the number are telling you not to lean on it. We think that's worth listening to.

The mechanical reason GMP swings so much is that it's thinly traded. A handful of trades among dealers can move the "market price" for an entire IPO's sentiment, which is a very different thing from the deep, liquid trading that sets a stock's price once it's actually listed. It's less like a stock price and more like asking three people at a party what they think a house down the street is worth. You might get a decent guess. You also might get a wildly overconfident one from whoever's had the most coffee that day.

So what do we actually look at?

Not GMP, and also, honestly, not "will this IPO pop on day one" at all. That's a different question from the one we think you should be asking.

We look at the same things a listing-gain chaser tends to skip: the business itself, its revenue and margin trend over multiple years rather than one hot quarter, its debt levels, how the IPO proceeds are actually being used (a fresh issue funding real expansion is a different animal from an offer-for-sale where existing owners are simply cashing out), and how the valuation compares to listed peers in the same industry. Alpine Texworld, for instance, showed strong profit growth on paper but also carried a debt-to-equity ratio of 2.35, a detail that matters a lot more to a three-year holder than to someone flipping shares on listing day (IndiaInfoline, 2026). That's the kind of thing GMP will never tell you, because GMP doesn't know or care what happens after day one.

We also just don't think "will I make a quick gain by tomorrow" is a useful question to build an investing habit around, even when it works. The four examples above show why: two out of four roughly rewarded the grey-market crowd, one badly disappointed them, and one is still an open question. A coin flip with occasionally better odds isn't a strategy, it's a habit that occasionally pays off, and habits that occasionally pay off are exactly the ones that are hardest to walk away from later.

The habit we'd rather you build instead

If an IPO's underlying business is genuinely strong, that strength doesn't expire at 10:00 am on listing day. A company worth owning is still worth owning next month, and next year, regardless of what the grey market guessed about its first hour of trading. If the business isn't strong, no amount of pre-listing hype changes that either; it just delays when the truth shows up in the price.

So here's the honest version of our answer, the one we'd give a friend rather than a client: check the fundamentals, size the position sensibly, decide before you apply whether you're actually comfortable holding this for years and not just for a day, and let the GMP number be background noise rather than a decision. If it happens to be right, fine. If it's wrong, and per the examples above, it's wrong often enough to matter, you won't have built your decision on it in the first place.

A few honest questions people ask us

Does this mean GMP is completely useless? Not completely. A strongly positive GMP alongside strong institutional subscription can be a weak signal of near-term sentiment. But "weak signal" is the operative phrase, not "reliable predictor," and the four examples above show why treating it as more than that goes wrong often enough to matter.

If GMP is this unreliable, why do so many financial sites publish it daily? Because there's real reader interest in it, and publishing an unofficial number with a disclaimer isn't the same as recommending you act on it. Most of the trackers we cited here do include that disclaimer, even while publishing the number prominently.

Should I never apply for an IPO, then? That's not what we're saying. We're saying the reason to apply should be the business, the valuation, and your own time horizon, not a number that changed by 50 percent in a week and a half for one of the IPOs discussed above.

What happened with Caliber Mining in the end? We genuinely don't know yet as of this writing; the issue was still in its bidding window. That's part of the point: if we can't tell you the answer with a live example sitting in front of us, a grey-market number three weeks earlier definitely couldn't either.
