When a company launches an Initial Public Offering (IPO), investors are not treated as one single group. Instead, they are classified into distinct categories such as RII, NII, QIB, and Anchor Investors. Each category has different eligibility criteria, investment limits, and roles in the IPO process. Understanding these categories helps investors interpret IPO subscription data and allotment outcomes.
IPO investor categories are classifications created to ensure fair participation and balanced allocation of shares among different types of investors. These categories help regulators and issuing companies distribute shares systematically between retail investors, high-net-worth individuals, and institutional participants.
By dividing investors into categories, IPOs aim to protect retail participation, facilitate participation by long-term institutional investors, and maintain stability during the listing process.. Each category has a predefined portion of shares reserved for it, which directly impacts subscription levels and allotment chances.
RII stands for Retail Individual Investor. This category includes individual investors who apply for shares worth up to ₹2 Lakh in an IPO. Retail investors usually apply through online platforms using their demat and linked bank accounts.
The RII category is meant to encourage wider public participation in the stock market, especially from small investors. To support this goal, a fixed portion of the IPO is reserved for retail applicants.
Key points about RII investors:
Investment amount is capped at ₹2 Lakh per IPO application
Applications are made through ASBA via banks or trading apps
Shares are allotted on a lottery basis if the issue is oversubscribed
All valid applications have equal chances, regardless of the exact amount applied within the limit
This category helps improve retail participation in new listings
Because of the lottery-based allotment, even small applications have the same probability of receiving shares when demand is high.
NII refers to Non-Institutional Investors, commonly known as High Net-Worth Individuals (HNIs). Investors who apply for more than ₹2 Lakh worth of shares fall under this category.
NII investors typically apply with larger amounts compared to retail investors, which often leads to intense competition in this segment.
Key points about NII investors:
Application amount is more than ₹2 Lakh
Allotment is done on a proportional basis, not through a lottery
The category is split into:
Small HNIs (lower investment slab)
Big HNIs (higher investment slab)
Higher demand can reduce the final allotment percentage
Subscription levels in this category can be very volatile
Since allotment depends on the total demand and application size, investors may receive only a portion of the shares they applied for.
QIB stands for Qualified Institutional Buyer. This category includes large and experienced institutional investors who actively participate in capital markets.
These investors are considered capable of assessing business risks and financial performance, which is why they receive a significant share of IPO allocations.
Examples of QIBs include:
Mutual funds
Insurance companies
Banks and financial institutions
Foreign Portfolio Investors (FPIs)
Key points about QIB category:
A large portion of IPO shares is reserved for QIBs
Allotment is strictly proportional to the amount applied
No upper investment limit applies
High levels of QIB subscription indicate the extent of institutional participation in the IPO
Their participation is often tracked closely, as it reflects institutional confidence in the company.
Anchor investors are a special group within the QIB category who invest in an IPO before it opens to the public. Their shares are allotted one working day prior to the IPO opening at the final issue price.
This early participation provides visibility into institutional involvement before the public subscription period.
Key points about anchor investors:
Only QIBs can participate as anchor investors
Allocation happens before retail and HNI bidding begins
Investment is made at the same price as the IPO issue price
Shares come with a lock-in period, so immediate selling is restricted
Their presence can influence overall investor confidence
Strong anchor participation is often highlighted in IPO announcements and can affect how the issue is viewed by retail and HNI investors.
The following comparison highlights how each category plays a unique role in the IPO ecosystem:

Different investor categories exist to balance participation across market segments. Retail investors are protected through reservations, while institutional investors provide long-term capital and market confidence.
This structure ensures price discovery, reduces volatility, and promotes fairness in share distribution. It also prevents any single group from dominating the IPO and supports a healthy listing process.
RII, NII, QIB, and Anchor Investors each serve a distinct purpose in an IPO. Retail investors bring widespread participation, NIIs add volume, QIBs contribute expertise and stability, and anchor investors set the tone before public bidding begins. Understanding these categories helps investors interpret IPO demand, subscription data, and allotment outcomes more effectively.

RII, NII, QIB, and anchor investors are classified based on investment size, eligibility, and allotment process. Retail investors apply with smaller amounts, while institutional and anchor investors participate with higher capital and distinct allocation mechanisms.
IPO investors are categorised into Retail Individual Investors, Non-Institutional Investors, Qualified Institutional Buyers, and Anchor Investors. These categories differ in application size, regulatory requirements, and allotment rules defined under the IPO framework.
Qualified Institutional Buyers include regulated financial institutions such as mutual funds, insurance companies, banks, and foreign portfolio investors. These investors participate in IPOs with large capital commitments and are considered professionally managed entities.
Anchor investors are large institutional investors who receive share allotments before the IPO opens for public subscription. Their participation helps establish price visibility and demand, though it does not indicate future performance or outcomes.
