If the Grey Market Premium is the "shadow price" whispered in the alleys, then IPO Subscription data is the roaring crowd in the stadium. During the three or so days an Initial Public Offering (IPO) is open, you will often see headlines screaming numbers like "Subscribed 50 times!" or "Retail portion fully booked in 1 hour!"
For the amateur investor, subscription figures are just a popularity contest. But for the seasoned financial expert, they are a complex dashboard revealing who is buying, how much smart money is flowing in, and most importantly how hard it will be to actually get your hands on shares.
Today, let’s decode IPO Subscription: the categories, the math, and the "herd mentality" traps you need to avoid.
In simple terms, IPO Subscription represents the demand for a company's shares compared to the supply available. It tells you how many times investors have applied for shares versus the total number of shares the company is actually offering.
Think of it as a ticket sales counter for a blockbuster movie. If there are 100 seats in the theater but 500 people are standing in line with cash in hand, the show is "oversubscribed."
Exact match.
Oversubscribed.
Red flag.
Just because an IPO is heavily subscribed doesn't always mean the company is fundamentally great. It often just means the "listing gain" sentiment is strong, fueled by market liquidity rather than long-term value.

Seeing 100x subscription from QIBs gives you confidence that "smart money" sees value here.
High oversubscription signals scarcity, which often drives prices up on listing day due to pent-up demand.
High subscription figures can be deceptive. Here is why you should never invest blindly just because a stock is oversubscribed.
QIBs wait until Day 3 to bid. Judging an IPO as a 'flop' on Day 2 is a classic amateur mistake.
Many HNIs use borrowed funds to flip stocks. If GMP crashes, this massive demand can evaporate instantly.
At 100x sub, your chance is 1 in 100. Tying up capital for terrible lottery odds isn't always smart.
Subscription numbers are a confirmation tool, not a strategy. They tell you if the wind is blowing in your favor, but they don't tell you if the ship is seaworthy.
Look at the QIB numbers first. If institutions are putting their money on the line, it's a safer bet. If only retail is oversubscribed while QIBs stay away, proceed with extreme caution—it might be a trap.
If an IPO fails to get at least 90% subscription, the issue is considered to have failed (devolved). In this scenario, the company must cancel the IPO and refund all the money collected from investors. However, usually, underwriters step in to buy the unsold portion to save the issue.
