India’s primary market has entered September 2026 on a busy note, with a mix of Mainboard and SME IPOs attracting investor attention. From strong subscription numbers to changing Grey Market Premium (GMP) trends, investors are once again closely watching the IPO market for potential listing opportunities.
However, the current IPO environment also highlights an important point: GMP alone should not be treated as a signal to invest. Investors need to look at the issue price, company fundamentals, valuation, subscription pattern, financial performance and broader market conditions before making a decision.
September IPO Market Begins With Strong Activity
The beginning of September has brought several IPOs into focus across the Mainboard and SME segments.
According to the latest IPO data, companies such as Deepa Jewellers, Purple Style Labs, Shanti Inorganics, Ashutosh Fibre and Phychem Technologies are among the issues that investors have been tracking around the September 1–3 period.
The current IPO calendar shows a wide variation in GMP trends. For example, Shanti Inorganics has been showing a relatively strong grey market premium, while Purple Style Labs has been trading with a much smaller premium expectation. Deepa Jewellers has also attracted attention as its GMP has moved during the subscription period.
This difference is a useful reminder that every IPO needs to be evaluated separately.
What Is GMP and Why Are Investors Watching It?
Grey Market Premium, commonly known as GMP, represents the premium at which IPO shares are reportedly being traded in the unofficial market before their stock-market listing.
For example, if an IPO has an upper price band of ₹100 and the reported GMP is ₹20, the implied estimated listing price would be around ₹120.
That would indicate a potential 20% premium over the issue price.
But there is an important catch.
GMP is unofficial and can change quickly. It is not a guarantee that the stock will list at the estimated price. Market sentiment, subscription numbers, overall market conditions and demand on the actual listing day can all affect the final outcome.
This is why investors should use GMP as one data point rather than the entire investment thesis.
Deepa Jewellers IPO Shows How Quickly GMP Can Change
Deepa Jewellers is one of the Mainboard IPOs attracting attention in the current market.
The IPO opened for subscription on September 1 and is scheduled to close on September 3, 2026. The price band is ₹168–₹177 per share, with a lot size of 84 shares. The latest available IPO data shows a reported GMP of around ₹44, implying a potential premium of approximately 24.86% over the upper price band.
However, GMP has been volatile during the issue period. Other market reports have also highlighted a decline in GMP during the subscription window, demonstrating why investors should avoid assuming that today's GMP will necessarily be tomorrow's listing premium.
The broader lesson is simple: GMP is dynamic.
SME IPOs Are Also Getting Attention
The activity isn't limited to Mainboard IPOs.
Several SME IPOs are also being tracked by investors during the first week of September. Shanti Inorganics, Ashutosh Fibre, Phychem Technologies and Farm Peace are examples of SME issues appearing on the current IPO calendar.
SME IPOs can sometimes show substantial GMP movements because of limited liquidity and strong investor interest. At the same time, they can carry higher risks than many Mainboard offerings.
Investors should therefore pay particular attention to:
- Financial performance
- Valuation
- Promoter background
- Issue utilisation
- Liquidity after listing
- Lot size and minimum investment
- Subscription pattern
- Business scalability
A high GMP should never replace this analysis.
Subscription Data Provides Another Important Signal
Subscription numbers can provide a useful picture of investor demand.
The recently completed ESDS Software Solution IPO, for example, attracted extremely strong demand. The ₹720 crore issue was subscribed 135.88 times, with particularly high participation from qualified institutional and non-institutional investors. The issue is scheduled to list on NSE and BSE on September 4, 2026.
Interestingly, the IPO also attracted considerable attention in the grey market before listing.
Such situations demonstrate why investors often track three numbers together:
IPO subscription + GMP + fundamentals
Looking at only one of these indicators can provide an incomplete picture.
GMP vs Fundamentals: Which Matters More?
For investors looking for quick listing gains, GMP can be useful for understanding current market sentiment.
For long-term investors, however, fundamentals should carry significantly more weight.
Before applying for an IPO, investors should consider:
1. Revenue and Profit Growth
Check whether the company's revenue and profit have grown consistently over the last few financial years.
2. Valuation
A company may have excellent growth but still be expensive compared with its listed peers.
3. IPO Structure
Investors should understand whether the IPO consists primarily of a fresh issue, an Offer for Sale (OFS), or a combination of both.
4. Use of IPO Proceeds
Fresh issue proceeds used for expansion, debt repayment or working capital can have different implications for the business.
5. Industry Outlook
A strong company operating in a declining industry may face different challenges compared with a company benefiting from long-term structural growth.
6. Subscription Quality
Overall subscription numbers are useful, but investors should also examine which investor categories are driving the demand.
Where Can Investors Track IPO GMP?
With several IPOs entering the market every month, tracking the latest information manually can become difficult.
GMP IPO Watch provides IPO-related information including GMP trends, price bands, subscription information, lot sizes, listing dates and IPO calendars.
Its live IPO list currently covers hundreds of IPO records across Mainboard, SME and SSE categories, allowing investors to compare issues in one place.
Investors can use GMP IPO Watch as a convenient starting point for tracking the latest grey market trends and IPO developments, while conducting their own research before making investment decisions.
What Should Investors Watch Next?
The September IPO pipeline suggests that the primary market could remain active in the coming weeks.
The key areas worth watching are:
- New Mainboard IPO announcements
- SME IPO launches
- Changes in GMP before listing
- Subscription momentum
- IPO allotment results
- Listing-day performance
- Post-listing price stability
- Market-wide sentiment
The performance of recently listed companies will also be important because successful listings can encourage more companies to enter the primary market.
Final Thoughts
September 2026 is shaping up to be another interesting period for India's IPO market.
There are plenty of opportunities for investors to explore, but the growing popularity of IPOs also makes disciplined research more important. A strong GMP may indicate positive market sentiment, but it does not guarantee listing gains or long-term returns.
The best approach is to combine GMP, subscription data, financial performance, valuation and business prospects before making an investment decision.
For investors who want to keep track of changing GMP figures and upcoming IPOs, GMP IPO Watch can be a useful resource for monitoring the market.
Ultimately, the goal shouldn't be simply to find the IPO with the highest GMP. The better question is:
Does the IPO offer a business and valuation that make sense beyond the listing day?
Disclaimer: IPO GMP figures are based on unofficial grey market activity and can change frequently. They should not be considered a guarantee of listing price or investment returns. Investors should conduct their own research and consult a qualified financial adviser before investing.
