FAQs

How is IPO allotment decided?

When an IPO is oversubscribed in the retail category, allotment is done via a lottery so each successful applicant gets at least one lot.

Does applying for more lots help?

In the retail category you are eligible for at most one lot, so extra lots in a single application do not raise your odds; separate PAN applications do.
