Imagine this situation:
Raj, a young investor from Lucknow, applied for a popular IPO using UPI during office hours. Later that evening, after reading deeper company analysis and discussing risks with friends, he decided the IPO was too risky. Like many first-time investors, he wondered:
“Can I still modify or cancel my IPO application?”
The answer is yes — but only while the IPO remains open for subscription.
This updated 2026 guide explains everything in simple language, including:

Why Investors Modify or Cancel IPO Applications
There are many reasons investors decide to modify or cancel an IPO application:
Better research after applying
Market sentiment changes
Wrong bid quantity entered
Incorrect UPI ID or bank details
Family or financial concerns
IPO valuation looks expensive
Need to free blocked funds
Retail investors have the highest flexibility in the IPO system. As long as the IPO subscription window is open, they can:
Increase or decrease bid quantity
Edit bid price
Withdraw the IPO application completely
However, rules differ for HNIs and institutional investors.
Official IPO Modification & Cancellation Rules (2026)
According to SEBI, NSE, and BSE IPO guidelines:
Retail Individual Investors (RII) can modify or cancel IPO applications during the subscription period.
HNI/NII investors cannot cancel bids after submission.
HNIs can only revise bids upward.
QIB investors also cannot withdraw bids.
Changes are allowed only during market hours while the IPO remains open.

Real-Life Example: Raj’s Smart IPO Decision
Raj checked his Groww app the next morning and found his IPO under “My Applications.” Initially, he reduced the bid amount after reviewing the company’s weak fundamentals. Later, he decided to completely cancel the application.
He also revoked the UPI mandate through Google Pay.
Within a few hours:
IPO status changed to “Cancelled”
Funds were unblocked within two days
Raj avoided a risky investment decision
The experience taught him an important lesson:
Research first, apply carefully, and use the flexibility available in the IPO system wisely.
Common Mistakes Beginners Should Avoid

Broker servers may slow down near closing time.
2. Forgetting UPI Mandate Revocation
Funds may remain blocked longer.
