A company launches an IPO at ₹500 per share. Trading begins. By the end of the day, it closes at ₹650. Investors cheer at the 30% listing gain. But the company may well be disappointed. It sold yesterday for ₹500 what the market is now willing to pay ₹650 for. The ₹150 windfall went to whomever got shares at the IPO price.

Two Prices Exist Within Days

An IPO creates an unusual marketplace. Before the listing, investment bankers and the issuer set a price through the issue process and the demand for it. Afterwards, thousands of buyers and sellers determine the price. These two pricing mechanisms can and do conflict.

If the market immediately discounts the IPO price, early investors are made to feel foolish. When the listing price exceeds the issue price, the company has benefited from IPO underpricing. The company raised the capital it needed. It may also have left money on the table.

Imagine Selling a House This Way

Suppose you sold your house for ₹1 crore. The buyer walked out, then turned around and sold it for ₹1.3 crore. You received ₹1 crore. It would be human nature to wonder if you could have gotten a higher price. An IPO listing gain is the same.

If the company issued 1 crore new shares, it could have generated another ₹100 crore by pricing them ₹100 higher, assuming demand was there at that price. That is a crucial assumption. The company cannot simply pick the highest possible price. An IPO has to have demand to clear the market.

Why Not Price Every IPO Perfectly?

Because the future price is unknowable. Bankers have to make their best guess at what the market will support before continuous two-way trading begins. They also have other incentives to underprice the IPO. A failed or undersubscribed offering is embarassing and can damage future fundraising.

Institutional investors who take allocation risk need some reward. A small discount creates demand and helps ensure the listing price is achieved. Pricing therefore involves a trade-off. Price too high and no one will buy. Price too low and the company leaves money on the table. The "correct" price is obvious to everyone with the benefit of hindsight.

Listing Gains Attract a Different Investor

For long-term investors, an IPO is an opportunity to own a piece of the action. For others, the company itself is a means to an end. The goal is to get an allotment, wait for the listing gain, then sell the shares to someone else at a higher price.

SEBI studied investor behaviour in IPOs and found that 54% of shares allotted to investors other than anchor investors were sold within one week of listing (Securities and Exchange Board of India). That's a stunning rate of turnover for securities that have only been in the market for a week. Many investors were clearly not interested in holding onto the shares for any length of time.

Bigger Listing Gains Encourage Faster Selling

SEBI's report on IPOs found what most people intuitively understand. Investors were more likely to sell if the listing gain was positive. A big listing gain turns an uncertain long-term investment into a sure thing in the short term. It encourages flipping.

The IPO is more of a vehicle to predict the near-term market than to invest in the long-term value of the company. That is why grey-market premiums and subscription multiples are such a popular barometer for retail investors. They indicate the potential listing gain, which in turn provides an estimate of the short-term value of investing in the IPO.

Oversubscription Does Not Mean Everyone Gets Rich

If the retail portion of an IPO is ten times subscribed, that does not mean ten times more shares are available. It means ten times more people are applying for the same number of shares. Some of those applicants are bound to be disappointed.

The headline may read that the IPO was subscribed 50×, but an investor who applied because of that headline has a very low chance of getting any meaningful allotment. Popularity creates demand. It does not create supply. This is another reason why the IPO can be like a lottery. The product on offer has value, but the prize is only available to a few.

A Listing Gain Is Not New Wealth for the Company

This is a critical point that is often overlooked. Assume a share is issued in an IPO for ₹500. The company gets the money in its bank account. When that share is later sold on the stock exchange for ₹650, the extra ₹150 goes to the new buyer, not the company. The company's market capitalisation has increased, but its cash balance has not. Market value and cash are two completely different metrics.

Sometimes the IPO Is Mostly an Exit

One of the most important distinctions in an IPO is the difference between a fresh issue and an offer for sale. In a fresh issue, the company issues new shares and raises capital. In an offer for sale, existing shareholders sell their shares. The money goes to the selling shareholders, not the operating company.

SEBI's report on IPOs noted that offer-for-sale components accounted for 64% of the amount raised by mainboard IPOs in November 2025, illustrating the importance of such transactions in facilitating shareholder exits. (Securities and Exchange Board of India) Two IPOs can have the same headline raising amount, but the money can go to completely different parties.

The Best IPO Is Not Necessarily the Biggest Pop

A big listing gain is great for investors. It makes the company feel good about its fundraising. It creates positive word-of-mouth for future offerings. But a 70% listing gain is also an indication that the company could have raised significantly more money by pricing the shares higher.

For the company, the best IPO is one that raises the maximum amount of money without underpricing. For investors, the best IPO is one that is significantly discounted to its intrinsic value. These goals are not entirely compatible. Every IPO is a negotiation between the two. When a stock price gains on the listing day, investors smile. The company may well be frowning.
