Diffusion Engineers IPO allotment probability

Your odds of an allotment in each category at the current subscription.

Retail (up to ₹2 L)
1 out of 86
~1.2% chance per PAN — based on 85.61x subscription. Winners get exactly 1 lot (₹14,784) by SEBI lottery, however many lots you bid.
Small HNI (₹2–10 L)
1 out of 216
~0.5% chance — based on 216.13x subscription. Lottery allots the minimum S-HNI application of 14 lots (₹2.1 L) per winner; bidding bigger doesn't improve odds.
Big HNI (above ₹10 L)
1 out of 203
~0.5% chance — based on 203.34x subscription. Lottery allots the minimum NII application of 14 lots (₹2.1 L) per winner, the same as S-HNI; any shares left over are allotted proportionately.
QIB (institutions)
95.74x
Proportionate allotment — at 95.74x, institutions receive ~1% of their bid. No lottery; not open to individual investors. Strong institutional endorsement.

Odds = allotment slots ÷ applications, or the subscription multiple where counts aren't available. Retail and HNI allotment is by lottery; QIB is proportionate. Not investment advice.

What does this subscription data mean?

IPO subscription data tells you how much demand exists for the shares being offered, broken down by investor category. Understanding each category helps you gauge the real sentiment behind the numbers:

  • 01 QIB (Qualified Institutional Buyers) — includes mutual funds, FIIs, insurance companies, and banks. QIBs do deep due diligence before bidding. A QIB subscription above 10x is a strong institutional endorsement. Watch QIB numbers closely on the final day — they often hold back and flood in after 3 PM.
  • 02 NII / HNI (Non-Institutional Investors) — high-net-worth individuals bidding above ₹2 lakh. NII allotment is proportionate (not lottery), so higher NII subscription means smaller per-lot allotment. Big HNI (B-HNI) bids above ₹10 lakh; Small HNI (S-HNI) bids ₹2–10 lakh.
  • 03 Retail — individual investors bidding up to ₹2 lakh. When retail is below 1x, everyone who applied gets full allotment. When oversubscribed, SEBI mandates a computerised lottery — only 1 lot per successful applicant regardless of how many lots you apply for.
  • 04 Overall Subscription — a blended multiple across all categories. A total subscription above 10x is considered strong; above 50x is exceptional and usually predicts strong listing gains.

Data sourced from BSE/NSE. Subscription numbers are updated during bidding hours (10 AM – 5 PM IST) on active subscription days.
