Planning to apply for an IPO? Before you do, it’s crucial to understand the different types of investors in IPO and how they influence who actually gets allotted shares.
Under SEBI's (Issue of Capital & Disclosure Requirements) Regulations, all IPOs are broadly divided into four key investor categories for reservation and allotment.
Here are the 4 main categories of investors in IPO:
Any individual (including resident individuals, Non-Resident Indians (NRIs), and Hindu Undivided Families (HUFs)) applying for shares with a total value up to ₹2 Lakh falls under the Retail Individual Investors (RIIs) category. These investors have the option to bid at the cut-off price, which is the highest price discovered during the book-building process. This increases their probability of receiving an allotment compared to bidding at a fixed, lower price.
The allocation of shares to RIIs in an IPO is determined by the company's route.
Due to high demand, shares in the RII segment are typically allocated through a lottery system to ensure fair distribution among applicants. The low investment limit makes IPO participation highly accessible for beginners and allows individuals to gain direct ownership in companies with potential for long-term growth.
NIIs, often referred to as High Net-Worth Individuals (HNIs), represent the second-largest category of non-retail investors. An investor applying for shares with a total value above ₹2 Lakh falls under the NII category. This segment includes wealthy individuals, Hindu Undivided Families (HUFs), corporate bodies, trusts, and institutions that are not registered as Qualified Institutional Buyers (QIBs). Unlike QIBs, NIIs do not require specific registration with SEBI.
A minimum of 15% of the total public issue is typically reserved for this category. NIIs are allotted shares in proportionate to their investment. This means if the segment is oversubscribed by 10 times, an investor who applied for 1,000 shares will receive approximately 100 shares.
Key Benefits:
QIBs are large, specialised investors that are crucial for the success of any major public issue. QIBs are professionally managed institutions, including Mutual Funds, Commercial Banks, Insurance Companies, and Foreign Portfolio Investors (FPIs) registered with SEBI. Their participation adds credibility to the IPO and helps ensure that a significant amount of capital is raised.
SEBI restricts the QIB portion to a maximum of 50% of the total net offer size. This is a regulatory measure to ensure the IPO is accessible to other investors (Retail and NIIs). Allotment within the QIB segment is also done on a proportionate basis.
Benefits for QIBs:
Anchor Investors are a specialised category of institutional buyers who commit early capital to the IPO. They are a special subset of QIBs (Qualified Institutional Buyers), including large mutual funds, insurance companies, sovereign wealth funds, and FPIs. They invest in the IPO one day before the public issue opens. Their early, substantial commitment adds credibility and stability to the IPO, boosting overall investor confidence. They commit large sums (minimum bid value of ₹10 Crore).
Up to 60% of the total QIB quota can be reserved for Anchor Investors. These investors are allotted shares at a fixed price (which is finalised within the IPO price band).
Key Benefits
Understanding the various types of IPO investors, QIBs, anchor investors, retail investors, and HNIs, gives you a clearer picture of how IPO demand is built and how shares are distributed. These categories of investors in IPOs ensure balanced participation, help maintain stability, and contribute to transparent price discovery in the Indian market.
By knowing the different types of investors in an IPO, you can make more informed decisions and better assess market sentiment for upcoming public issues.
