On: October 18, 2026 9:57 AM

Welcome back to EliteBulletin’s Daily IPO GMP Roundup, your ultimate destination for real-time insights into the primary market. Today, we are dissecting a high-stakes batch of mainboard IPOs currently battling for investor capital. As bidding windows rush toward their close, let’s dive straight into the numbers to see where the smart money is heading—and which listings are leaving investors hanging.

Overall Market Sentiment: A Cautious Landscape

The primary market sentiment today can best be described as cautiously selective. While retail and institutional investors are showing genuine interest in high-tech and defense-adjacent plays, overall grey market premiums (GMP) remain completely flat across the board at Rs. 0. With multiple major IPOs locking horns for liquidity simultaneously, subscribers are being extremely pickier than usual, avoiding broad-brush bidding in favor of fundamental strength.

Spotlight on Active IPOs: Subscription vs. GMP Reality

Let’s break down how the current active mainboard offerings are performing as we approach their final bidding hours on October 19, 2026:

  • Tonbo Imaging India Limited (TONBO): Standing tall as the clear momentum leader of the pack. With an issue price band of Rs.665 to Rs.700 and a lot size of 21 shares, Tonbo has successfully raced ahead to pull in a total subscription of 5.20x. Despite a flat GMP of Rs. 0, its robust subscription numbers show strong investor conviction.
  • Bonfiglioli Transmissions Limited (BONFIG): Priced between Rs.558 and Rs.586 (lot size: 25), this industrial transmission giant has managed a moderate subscription rate of 0.71x. While it hasn’t crossed the fully subscribed mark yet, it is hovering close with a steady push expected before closure.
  • Sahajanand Medical Technologies Limited (SMT): The medical tech player, carrying an issue price of Rs.327 to Rs.344 (lot size: 43), is currently seeing quieter traction with a 0.28x subscription rate and a stagnant Rs. 0 GMP.
  • Zetwerk Manufacturing Businesses Limited (ZETWERK): This much-talked-about manufacturing network play is currently lagging behind in the subscription race. Priced affordably at Rs.143 to Rs.151 (lot size: 99), it has only logged a 0.19x subscription so far, accompanied by a flat Rs. 0 GMP.

Which IPO Has the Highest GMP?

To be completely transparent with our readers: None of the active IPOs are currently commanding a positive GMP. Across Tonbo Imaging, Bonfiglioli Transmissions, Sahajanand Medical, and Zetwerk, the grey market premium sits firmly at Rs. 0. In a flat GMP environment like today’s, seasoned investors are relying less on grey market whispers and focusing heavily on fundamental subscriptions and long-term sector growth.

Which IPO is Struggling?

While no stock is technically “crashing,” Zetwerk Manufacturing Businesses is currently seeing the softest momentum on the board. Trailing with just 0.18x subscription, it needs a massive surge in institutional bidding over its final hours to cross the finish line comfortably. Similarly, Sahajanand Medical Technologies at 0.28x requires a late-surge rush from retail and QIB participants.

Where is the Momentum Today?

If you are looking for where the actual pulse is, Tonbo Imaging India Limited is capturing almost all the oxygen in the room. Crossing the 5x subscription threshold while other peers struggle to break past 1x proves that investors are willing to back specialized tech and defense-oriented plays, even when the grey market is playing it safe with zero premium indicators.
