Tenneco Clean Air India IPO allotment probability

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

Retail (up to ₹2 L)
1 in 6
~19.6% chance per PAN — based on 5.11x subscription. Winners get exactly 1 lot (₹14,689) by SEBI lottery, however many lots you bid.
Small HNI (₹2–10 L)
1 in 29
~3.5% chance — based on 28.2x 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 in 48
~2.1% chance — based on 47.01x subscription. Lottery allots the minimum B-HNI application of 69 lots (₹10.1 L) per winner; the rest is proportionate.
QIB (institutions)
166.42x
Proportionate allotment — at 166.42x, institutions receive ~0.6% of their bid. No lottery; not open to individual investors. Strong institutional endorsement.

Odds marked with applicant counts are computed from the exchange's actual application data (applicants ÷ allotment slots); others assume minimum-size bids at the current subscription multiple. Retail and HNI allotment is by SEBI-mandated lottery of the minimum application when oversubscribed; QIB allotment is proportionate. Numbers move until subscription closes. This is 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.
