Top 10 Mainboard IPOs - By Subscription: 2025

When the demand for shares in an IPO is higher than the number of shares offered by the company, it results in oversubscription

Companies with strong fundamentals, trusted brands, large bids from institutional investors, reasonable issue pricing, and bullish market conditions often witness heavy demand, leading to oversubscription. An oversubscribed issue is generally considered successful, with the possibility of premium listing due to the huge demand.

As per SEBI rules, in the event of oversubscription, the first priority is to ensure that as many investors as possible receive at least one lot of shares in their Demat account.

Listed below are the Top 10 Oversubscribed Mainboard IPOs of 2025, along with the breakup of subscriptions across investor categories.
