Why IPO Allotment Is Not Guaranteed
Introduction
Many investors assume that applying for an IPO automatically leads to share allotment.
In reality, IPO allotment is not guaranteed, especially when demand exceeds available shares.
Limited Number of Shares
Every IPO has a fixed number of shares available for allotment.
When applications exceed this number, it becomes mathematically impossible to allot shares to everyone.
Oversubscription Leads to Competition
IPO oversubscription occurs when demand is higher than supply.
Higher oversubscription means more applicants competing for the same shares, reducing individual chances of allotment.
Category-Wise Reservation of Shares
IPO shares are reserved separately for different investor categories such as Retail, NII, and QIB.
Oversubscription in one category does not affect allotment in another category, but it can eliminate guarantees within that category.
Lottery-Based Allotment in Retail Category
In heavily oversubscribed retail IPOs, allotment is often conducted through a lottery system.
Each valid application has an equal chance or no chance, regardless of application timing or expectations.
Proportionate Allotment May Still Reduce Quantity
In categories where allotment is proportionate, applicants may still receive fewer shares than applied for.
Even a valid application does not ensure full allotment of requested quantity.
Invalid or Rejected Applications
Applications may be rejected due to technical or compliance reasons.
- Incorrect PAN details
- Invalid demat account
- Multiple applications using the same PAN
- Non-compliance with application rules
Price and Cut-Off Bids Affect Priority
Bids placed below the cut-off price may receive lower priority or no allotment.
Cut-off bids are considered first, and remaining shares are allotted to price bids if available.
Final Allotment Is Done by the Registrar
IPO allotment is carried out exclusively by the official registrar.
No tool, estimate, or expectation can influence the registrar’s final decision.
IPO Allotment Probability Is Not a Guarantee
Probability figures only describe possible outcomes based on assumptions and public data.
They do not predict, assure, or promise actual allotment.
Key Reasons Allotment Is Not Guaranteed
- Limited number of shares
- High oversubscription
- Category-wise allocation rules
- Lottery or proportionate allotment systems
- Application rejections or bid priority
Final Note
Applying for an IPO means requesting shares, not reserving them.
Investors should always rely only on the official allotment results published by the registrar.
