Why IPOs get oversubscribed

With Indians shifting from traditional investments such as real estate and gold to the equity market, India is emerging as a global leader in Initial Public Offers (IPOs), with issuances in FY26 being 20% higher than FY25.

IPOs have become a buzzword for both beginners and seasoned investors aiming for wealth creation or quick listing gains. Many IPOs get oversubscribed based purely on hype, regardless of the company's fundamentals.

Let’s understand in detail why IPOs get oversubscribed and whether you should invest in them.

What Does IPO Oversubscription Mean?

Oversubscription occurs when the demand for new shares issued exceeds the available supply in an IPO. This indicates that there are more willing to buy the shares than the shares available for sale, signifying positive market sentiment and strong investor confidence in the shares' performance.

An oversubscribed IPO can list at a higher price on the stock market on the listing date, as investors who weren’t allotted the shares would want to purchase them in the secondary market.

How is IPO Subscription Level Measured?

IPO subscription is measured in real time by stock exchanges as a multiple of the shares available for sale. It is measured as the ratio of:

IPO Subscription = Total Number of Shares Bidding for / Total Number of Shares for Sale.

For example, a company offers 10,000 shares but receives applications for 30,000 shares, then it is considered 3x oversubscribed.

IPO subscription is calculated for different investor categories such as retail, QIBs (Qualified Institutional Buyers), and HNIs (High Net Worth Individuals). This helps investors understand which types of players are applying for the IPO. Typically, when HNIs and QIBs oversubscribe, it signals strong confidence in the company's future performance, attracting retail investor participation.

IPO Subscription Levels:

The following is a breakdown of subscription levels and their interpretation.

• Below 1x Subscription

If the IPO subscription is below 1x, it signals weak demand for the shares.

• 1x – 2x Subscription

An IPO with a subscription between 1–2x is considered to have moderate demand.

• 2x – 10x Subscription

If an IPO has 2x – 10x subscriptions, it is considered to have healthy demand.

• Above 10x Subscription

An IPO with above 10x subscription is considered to have high demand and is significantly oversubscribed.

What Happens When an IPO Is Oversubscribed?

For retail investors, when an IPO is oversubscribed, shares are allotted using the lottery system to decide who gets how many shares. An investor may receive only one lot or no shares at all. The higher the oversubscription, the lower the chances of receiving shares.

For HNIs, shares are allotted on a pro-rata basis, meaning if an IPO is oversubscribed by 10 times, the HNI may receive 1/10th of the bid placed.

Often, highly oversubscribed shares list at a premium, offering quick and significant gains to investors. In some cases, companies may choose to sell more shares if the demand is high to raise more capital.

Pro Tip: Use ASBA when applying for IPOs, ensuring your fund remains in your bank account in case you’re not allotted shares.
