Tempsens Instruments IPO - Day 2 Subscription Status
Day 1 closed with the issue subscribed 4.93 times overall, after getting fully booked within just an hour of opening. Demand has accelerated dramatically on Day 2, with the overall figure climbing to 11.70x by midday.
What Day 2 Numbers Indicate
NII has driven this surge in dramatic fashion, now at 25.29x, with small HNIs (38.75x) running well ahead of big HNIs (18.56x). This kind of acceleration in the HNI segment points to growing conviction around listing gains, even this early in a five-day bidding window.
Retail has also jumped sharply, from 5.55x at Day 1's close to 11.91x by Day 2's midday, and the employee quota is running hotter still at 18.62x. QIB has crossed full subscription too, now at 1.07x, up from just 0.04x at Day 1's close, an early signal of institutional interest, though QIB bids typically continue to build meaningfully in the closing days.
Overall subscription at 11.70x by Day 2's midday confirms the issue has moved firmly into heavily oversubscribed territory, with every single category now past full subscription. With three more bidding days still ahead, this level of early demand suggests the final tally could climb significantly further as the window heads toward its August 24 close.

Should You Apply for Tempsens Instruments IPO?
A few things worth weighing before you decide:
- It's a mix of fresh issue and offer for sale, with the ₹95 crore fresh issue going toward capital expenditure for electrical heating and specialised cable solutions, along with prepayment or repayment of certain outstanding borrowings, while the larger ₹555 crore OFS portion goes to existing shareholders selling part of their stake.
- Tempsens Instruments is the market leader in India's temperature sensing space, holding a 21.3% market share in the smaller, specialised non-contact temperature sensing segment, which gives it meaningful pricing power.
- The company raised ₹194.55 crore from anchor investors ahead of opening, and has developed a significant patent portfolio backed by an in-house R&D team of 83 people.
- Every category, QIB (1.07x), NII (25.29x), retail (11.91x), and employees (18.62x), was already past full subscription by Day 2's midday, reflecting broad-based investor conviction across the board.
- With demand already running well ahead of the shares on offer in every category, allotment for retail and NII is very likely to be decided by lottery.
