MUMBAI: Dalal Street’s primary market entered high gear on Thursday as institutional and retail participants mobilized capital across multiple tranches, led by the high-profile tonbo imaging and bonfiglioli ipo pipeline alongside customer experience major Fusion CX. The unprecedented convergence of six concurrent public offerings across mainboard and SME segments underscores deep liquidity reserves, even as secondary indices face macro fluctuations driven by offshore monetary cues.
⚡ Quick Highlights: Tonbo Imaging, Bonfiglioli IPOs Open: Check GMP & Details
Bengaluru-headquartered Tonbo Imaging has taken center stage in the current issue roster, leveraging its niche position as an indigenous developer of electro-optical and thermal imaging payloads for global aerospace and autonomous systems. The Rs 1,150 crore offering features a balanced mix of fresh capital raise and an offer-for-sale (OFS) component, with proceeds designated towards expanding domestic chip-level sensor packaging facilities and international defense sales pipelines.
Market observers note that Tonbo’s proprietary sensor architecture positions it advantageously against traditional legacy imports. Even as global macro signals remain cautious after the Nasdaq Slumps 2% as Hot US Inflation Data Ignites Federal Reserve Rate Hike Fears, domestic high-conviction defense electronics continue to command premium multiples from institutional desks.
“Niche defense electronics manufacturing provides sustained multi-year earnings visibility, making deeptech defense suppliers highly insulated from short-term secondary market headwinds.” — Rajan Swaminathan, Head of Research, Apex Capital Insights

Below is the detailed comparative breakdown of active initial public offerings open for subscription on Thursday, October 15, 2026, outlining price bands, issue valuations, minimum bid lots, and grey market premium indicators.
| Issuer Name | Issue Size (Rs Cr) | Price Band (Rs) | Lot Size (Shares) | Indicative GMP (%) |
|---|---|---|---|---|
| Tonbo Imaging | 1,150 | 430 – 455 | 32 | +28% |
| Bonfiglioli Transmissions | 1,800 | 510 – 540 | 27 | +19% |

Italian engineering giant’s domestic subsidiary, Bonfiglioli Transmissions, presents a pure-play bet on India’s capital goods expansion and renewable infrastructure push. Generating steady cash flows from industrial gearboxes and wind turbine pitch drives, the company’s Rs 1,800 crore offer appeals directly to long-only institutional portfolios hunting for non-cyclical manufacturing assets with robust return on capital employed (ROCE).
Simultaneously, Fusion CX represents the enterprise services spectrum, capitalizing on digital transformation mandates and omnichannel customer engagement. While enterprise software and IT solution providers have seen renewed operational interest—as reflected when Nifty IT Soars 4% as TCS, Infosys and Coforge Spark 2,000-Point Rally: Key Catalysts Behind Tech Surge—Fusion CX seeks to fund international delivery hubs across Southeast Asia through its public float.
“The simultaneous arrival of precision engineering like Bonfiglioli and enterprise service players like Fusion CX gives portfolio allocators a balanced spread across traditional industrial and new-age digital cash flows.” — Sunita Aggarwal, Equity Strategist, Mewar Equities
Lending massive institutional credibility to Dalal Street’s current IPO feast, contract manufacturing unicorn Zetwerk Manufacturing concluded an explosive anchor book round, mobilizing Rs 2,251 crore ahead of its retail opening on October 15. The anchor allocation list reads like a global financial directory, with BlackRock, Goldman Sachs, Nomura, Abu Dhabi Investment Authority (ADIA), and top-tier domestic mutual funds scooping up their respective maximum allowable quotas.
This formidable institutional backing has dramatically spilled over into Day 1 bidding metrics. Across both mainboard counters and specialized issues like Shellz India, Qualified Institutional Buyers (QIB) and high-net-worth individuals (HNIs) demonstrated decisive early commitment, dispelling liquidity fatigue worries.

“When global tier-1 sovereign entities absorb large anchor books within hours, it validates the structural durability of Indian supply-chain manufacturing assets on the global stage.” — Vikram Sethi, Managing Director, Axis Institutional Equities
Grey Market Premium (GMP) readings across unofficial trading hubs in Rajkot, Ahmedabad, and Mumbai indicate sustained investor appetite. Tonbo Imaging is commanding an unofficial premium of Rs 125–130 per share (+28%), while Zetwerk maintains steady grey trades near Rs 200 (+31%). Bonfiglioli Transmissions and Shellz India are similarly logging double-digit premiums over their respective upper price bands.
Investment bankers highlight that underwriters are deliberately pricing these multi-sectoral mid-cap and large-cap issues with demonstrable ‘money left on the table’. This disciplined pricing strategy is vital to ensure broad-based primary liquidity ahead of the unprecedented Rs 30,000 crore Reliance Jio IPO scheduled to open its doors on October 21.
“Merchant bankers are actively avoiding peak-cycle valuations. Leaving money on the table ensures successful listings and preserves market appetite for mega-issues lined up later this month.” — Devendra Chundawat, Partner, Lake City Merchant Banking
For retail and non-institutional investors navigating this multi-issue feast, capital allocation requires strict adherence to balance-sheet fundamentals. While Tonbo Imaging offers unmatched deeptech defense scarcity value and Bonfiglioli provides stable cash generation, investors should closely track working capital cycles and post-listing lock-in schedules for pre-IPO venture funds.
Wealth managers advise spreading application lots across diverse household demat accounts to optimize mainboard allotment probability under SEBI’s randomized draw mechanism, while reserving contingency liquidity for late October’s historic telecommunications offerings.
“Selective bidding based on EBITDA conversion and reasonable debt levels is paramount when six issues vie for identical liquidity simultaneously.” — Meenakshi Vyas, Portfolio Manager, Mewar Wealth Advisory
Six key public issues are actively open for bidding, including Tonbo Imaging, Bonfiglioli Transmissions, Fusion CX, Zetwerk Manufacturing, Shellz India, and Crest Micro Life.
In unofficial grey market trades, Tonbo Imaging is trading at a premium of approximately 28% (Rs 125–130 over the upper band), while Bonfiglioli Transmissions is commanding an estimated premium of 19% (Rs 95–102).
Zetwerk successfully mopped up Rs 2,251 crore from marquee institutional anchors including BlackRock, Goldman Sachs, Nomura, and leading Indian mutual fund houses at the upper price band of Rs 645 per share.
Under the standard T+3 settlement cycle mandated by SEBI, allotment for the current batch will finalize within 24–48 hours of issue closure, with listings on the BSE and NSE scheduled between October 20 and October 23, 2026.
