What this means

  • Retail is 5.20× subscribed. Each applicant has a ~19.2% chance of getting one minimum lot.
  • Applying multiple times from the same PAN is not allowed and will be rejected.

How allotment actually works

  • Retail (≤₹2L application): If oversubscribed, allotment is by lottery. Each successful applicant gets exactly one minimum lot. Multiple lots applied don't increase your odds — you still either get 1 lot or zero.
  • S-HNI (₹2L–₹10L): Proportionate allotment. If 5× subscribed, you get ~20% of applied.
  • B-HNI (>₹10L): Same as S-HNI — proportionate.
  • QIB: Discretionary within the QIB pool. Anchor allotment is locked in 60% of QIB before issue opens.
  • Pro tip: Multiple PANs from the same household are pooled — only one application counts. Apply early to avoid bid rejections close to deadline.
