If a company is worth up to ₹1,600 crore, it still need to offer at least 25% of its shares to the public.
For bigger players (₹1,600-4,000 crore), the minimum is ₹400 crore.
As market cap goes up, so does flexibility: companies between ₹4,000 and ₹50,000 crore need to float at least 10%, and those above that have even lower percentage requirements or fixed rupee amounts, making life much simpler for India's giants.

There are clear deadlines too: For very large issuers that list with less than 15% public shareholding, the rules allow five years to reach 15% and 10 years to reach 25%.
This shift comes as Indian IPOs are booming: IPO activity has been strong in recent years.
The bottom line: these changes make it easier for more big brands to join the stock market, and for young investors like you to get in on the action.
