Rubicon Research, a speciality pharmaceutical formulations company, launched its IPO in October 2025. The issue combined a fresh issue and an offer-for-sale, raising substantial interest from retail, non-institutional and institutional investors. Given the firm’s focus on complex generics and contract manufacturing, the IPO drew attention for both its business model and expected listing performance.
IPO Name, Price Band and Lot Size
The issue was listed as Rubicon Research Ltd. The IPO price band was set at ₹461 to ₹485 per share. Retail investors could apply in standard lot sizes applicable to the issue; the minimum application value depended on the lot multiple assigned for retail applicants.
IPO Date & Subscription Status
The public offer window ran in early–mid October 2025. The IPO saw strong subscription across categories and closed with a high overall subscription ratio, reflecting considerable investor demand. High subscription intensifies focus on the allotment process and expected listing behaviour.

Grey Market Premium (GMP)
Before listing, grey market indicators suggested positive sentiment. GMP quotes in informal markets signalled that many expected a listing premium on debut. Keep in mind GMP is an unofficial indicator and can change quickly based on market sentiment and last-minute flows.
Corporate Events and Listing Date
Following allotment, the next key event is the stock’s listing on public exchanges. The tentative listing date was set in mid-October 2025, subject to exchange confirmations. Listing day typically sees a mix of short-term trading and investor reallocation as brokers and funds digest the new stock.
Dividend, Bonus & Stock Price
At the time of the IPO, there were no special dividend or bonus declarations tied to the offer. The post-listing stock price is influenced by listing demand, GMP, analyst views and the company’s underlying fundamentals. Investors should track early trading volumes and broker research to form short-term expectations.
Allotment Status & How It Works
The allotment process determines who receives shares when an issue is oversubscribed. Basis of allotment is finalised by the registrar — typically within a few days after the issue closes. If you applied, your allotted shares (if any) will be credited to your demat account and refunds (if not allotted) will be processed back to the bank account used for ASBA.
Subscription Status
Rubicon Research experienced robust subscription across categories. Strong retail and institutional demand generally increases the probability of partial allotment for many applicants and higher listing volatility as market participants price the debut.
Is Rubicon Research a Multibagger Stock?
Calling an IPO a “multibagger” is speculative. While initial subscription and GMP can indicate listing appetite, long-term returns depend on revenue growth, margin improvement, customer concentration, regulatory environment and management execution. Evaluate fundamentals before making long-term bets.
