GMP Crosses 100%
The biggest talking point around the Tempsens Instruments IPO is its latest GMP trend.
Grey-market indications have moved to around ₹300 or more, which is equivalent to roughly a 100% premium over the IPO's upper price of ₹300. Some market trackers have reported GMP levels above ₹300, indicating expectations of a potentially strong listing.
At a hypothetical GMP of ₹300, the implied price would be around ₹600 per share.
However, investors should remember that this is only an unofficial grey-market indication. GMP can change sharply before listing and does not guarantee the actual listing price.
Strong Subscription Demand
The IPO has also received strong demand from investors.
According to the latest available subscription data, the issue had been subscribed more than 21 times, with particularly strong participation from non-institutional investors.
The NII portion was subscribed nearly 53 times, while the retail portion was subscribed more than 18 times. QIB participation stood above 3 times in the available data.
On the final day, reports indicated that overall subscription had moved substantially higher, highlighting the strong demand for the issue.
What Does Tempsens Instruments Do?
Tempsens Instruments is a Rajasthan-based thermal engineering and specialised cable manufacturer.
The company manufactures temperature-sensing solutions, electrical heating solutions and specialised cables. Its product portfolio includes thermocouples, resistance temperature detectors, infrared pyrometers, thermal imagers and other industrial temperature measurement products.
The company also has an international presence, with exports contributing a meaningful portion of its revenue.
Where Will the IPO Money Go?
The ₹650 crore IPO includes both a fresh issue and an Offer for Sale.
According to the available IPO details, approximately ₹95 crore is being raised through the fresh issue, while the remaining portion is an OFS by existing shareholders.
The fresh issue proceeds are planned to be used primarily for:
- Capital expenditure for electrical heating solutions
- Expansion of specialised cable solutions
- Repayment or prepayment of outstanding borrowings
- General corporate purposes
Around ₹55 crore has been earmarked toward repayment or prepayment of borrowings.
Why Are Investors Watching This IPO?
There are several reasons behind the strong interest in Tempsens Instruments.
First, the company operates in a specialised industrial segment with applications across sectors such as metals, petrochemicals and other industrial businesses.
Second, the company has reported revenue growth and has an established export business.
Third, the IPO has attracted substantial demand from non-institutional investors, while the grey market has also remained highly positive.
These factors have combined to make Tempsens one of the most closely watched IPOs of the current month.
But GMP Is Not Everything
The strong GMP may look attractive, but investors should not make an IPO decision based only on grey-market premiums.
Tempsens has exposure to cyclical industries, customer concentration and export-related risks. The company's performance can also be affected by raw material prices and industrial demand.
Therefore, investors should evaluate the company's financials, valuation, business prospects and risk factors before applying.
Tempsens Instruments IPO Allotment and Listing Date

Final Take
The Tempsens Instruments IPO has emerged as one of the strongest IPO stories of August, with a combination of heavy subscription demand and a GMP that has crossed the 100% mark in unofficial market indications.
The key question now is whether the strong grey-market sentiment will translate into an equally strong listing when the shares begin trading.
For investors who have already applied, the next important event will be the IPO allotment status. For those still considering an application, today is the final opportunity to participate in the issue.
