Note: Grey market premiums (GMP) are unofficial, market-reported figures collected from public GMP trackers as of Monday morning (~7:30 AM IST). They are not regulated, not SEBI-endorsed, and can change quickly through the day.

Biggest GMP Movers
- Tonbo Imaging is the runaway leader — ₹515 (~74%) as of Monday morning, ticking up from ₹505 on Sunday, and firmly in line with its 7.78x subscription. It is the only IPO closing today with a genuinely hot grey market.
- Jio Platforms GMP has firmed to ₹245–₹250 (~22%) from ₹235 on Sunday, reflecting the media-reported ~₹2.5 lakh crore early institutional demand (about 8x the ₹30,213 crore issue) ahead of today's anchor book.
- Bonfiglioli recovered to ₹130 (+22.2%) after a soft patch — interesting because subscription stands at only ~0.99x going into the final day.
- Zetwerk is the clear laggard: GMP has faded from ~₹20 mid-last-week to just ₹5–₹7 (~3–5%), matching its weak 0.31x subscription.
- Shellz India (SME) GMP readings are mixed across trackers (₹0 to ₹35); the median suggests roughly ₹24 (~13%), worth watching as it closes today.
5 IPOs Close Bidding Today
The final bidding day is today for the five issues that opened on 15 October. Tracker-reported subscription as of Monday morning:
| IPO | Size | Subscription (tracker-reported) | GMP (unofficial) | Allotment / Listing |
|---|---|---|---|---|
| Tonbo Imaging | ₹852 cr | 7.78x | ₹500–₹525 (~74%) | Allotment 21 Oct; lists 23 Oct |
| Bonfiglioli Transmissions | ~₹2,534 cr | 0.99x | ₹129–₹140 (~22%) | Allotment 21 Oct; lists 23 Oct |
| Sahajanand Medical | ₹475 cr | 0.83x | ₹15–₹25 (~4–7%) | Allotment 21 Oct; lists 23 Oct |
| Zetwerk | ~₹5,013 cr | 0.31x | ₹5–₹7 (~3–5%) | Allotment 21 Oct; lists 23 Oct |
| Shellz India (SME) | ₹60 cr | 0.89–0.91x | ₹24–₹35 (~13–20%) | Allotment 21 Oct; lists 23 Oct |
Only Tonbo is comfortably oversubscribed heading into the close. The rest — especially Zetwerk and Sahajanand — will need a strong final-day push from QIBs to build a comfortable book. Allotment for all five is expected on 21 October, with listing on 23 October.
Jio Platforms Anchor Book Opens Today
The main event of the day: the Jio Platforms anchor book opens today, 19 October, ahead of the public issue on 21–23 October. This is the first formal reading of institutional demand for India's biggest-ever IPO (₹30,213 crore, ₹1,065–₹1,119, 12-share lot).
- Media reports point to roughly ₹2.5 lakh crore in early institutional demand — about 8x the issue size — with GIC, Norges Bank, ADIA, QIA, BlackRock, Fidelity, Capital Group, LIC, SBI MF and HDFC MF reportedly in the queue. (These are media-reported indications, not formal subscriptions.)
- The issue includes a ₹2,500 crore RIL-shareholder reservation (record date 14 October) and a ₹500 crore employee quota.
- Broking platforms (Groww, Zerodha Kite, Upstox, ICICI Direct) have enabled pre-application, queued to hit exchanges at 10 AM on 21 October.
