Understanding the Retail Allotment Lottery Mechanism
With the retail quota standing oversubscribed at 4.85x, SEBI's proportionate retail allotment regulations dictate that every successful applicant will receive exactly one minimum lot of 182 shares (₹14,924) via a computerized draw. Bidding for multiple retail lots does not increase allotment probability over submitting single-lot bids across unique family PAN accounts. Read our mathematical guide on Why Multiple Retail Lots Do Not Improve Allotment Odds.
3. Price Band, Lot Size & Investment Thresholds
