Tempsens Instruments IPO Day 1 Subscription Status
The ₹650 crore public issue received bids for about 9 crore shares against roughly 1.52 crore shares available for public bidding, taking the overall subscription to 5.93 times.
| Investor category | Day 1 subscription |
| Qualified Institutional Buyers (QIBs) | 0.05x |
| Non-Institutional Investors (NIIs) | 12.50x |
| Retail Individual Investors | 6.44x |
| Overall | 5.93x |
The strongest response came from NIIs, where bids were 12.50 times the shares reserved for the category. Retail demand was also above the overall multiple at 6.44 times. QIB participation remained limited on the opening day.
Subscription multiples measure the quantity of shares bid for relative to shares reserved in each category. They do not represent the number of unique applicants. Category allocation also matters, so a higher multiple in a smaller reserved bucket should not be compared mechanically with a larger category.
What the Day 1 Subscription Numbers Indicate So Far
Day 1 demand was concentrated mainly in the NII and retail portions rather than being broad-based across all investor groups. The NII category crossed double-digit subscription, while retail demand also moved well beyond full coverage.
QIB demand, at 0.05 times, was modest at this stage. Institutional participation often builds later in the bidding period, but Day 1 data alone does not indicate how that category will finish. The more useful signal on Day 2 will be whether demand broadens beyond NII and retail investors.
Tempsens Instruments IPO GMP Today and Estimated Listing Price
Tempsens Instruments IPO GMP was around ₹230 on 20 August 2026, compared with a previous available reading of ₹220 earlier the same day. That indicates an increase of ₹10.
| GMP observation | Premium | Movement |
| Current, 20 August 2026 | ₹230 | Up |
| Previous available reading, morning (9:00 a.m. to 10:59 a.m. IST) on 20 August 2026 | ₹220 | +₹10 |
At the upper price band of ₹300, a ₹230 GMP implies an indicative price of ₹530 per share. The calculation is ₹300 + ₹230 = ₹530. The GMP percentage is about 76.7%, calculated as ₹230 divided by ₹300 and multiplied by 100.
GMP is unofficial, unregulated, and can change quickly. It is not published by the Securities and Exchange Board of India (SEBI), National Stock Exchange of India (NSE), or BSE Limited (BSE), and it does not guarantee the actual listing price or listing gains.
What Stands Out in Today’s Bidding
Two signals stand out. First, NIIs were the clear Day 1 demand driver at 12.50 times, while retail investors also subscribed their portion 6.44 times. Second, the GMP strengthened to ₹230, so both bidding demand outside QIBs and the unofficial grey-market signal were positive on the opening day.
There are also limits to these readings. QIB participation was only 0.05 times, so demand was not yet broad-based. Separately, neither high subscription nor a high GMP establishes fair valuation, business quality, or future returns. GMP can also reverse before listing.

Brief Company and Financial Context
Tempsens Instruments is a thermal engineering and specialised cable manufacturer that designs temperature-sensing solutions, electrical heating systems, and specialised cables for industrial customers. In financial year 2025-26, total revenue rose to ₹455.86 crore from ₹382.47 crore a year earlier, while profit after tax increased to ₹71.07 crore from ₹62.56 crore.
The company plans to use fresh-issue proceeds for capital expenditure in electrical heating and specialised cable solutions, repayment of certain borrowings, and general corporate purposes. One valuation consideration is that the IPO was priced at about 35.4 times FY26 earnings at the upper band, leaving investors to assess whether growth justifies that multiple.
What Happens Next
Day 2 bidding is scheduled for 21 August 2026. The main figures to watch are whether QIB participation rises, whether NII demand continues to lead, whether retail subscription keeps building, and whether the GMP holds near its current level or changes direction. The IPO is scheduled to close on 24 August 2026.
