IPO GMP Today (23 October 2026): Jio & Paras Close, 5 IPOs List
Friday, 23 October 2026 is one of the busiest primary-market days of the year: Jio Platforms (₹30,213 crore) and Paras Healthcare (₹1,450 crore) close for subscription today, five IPOs list — Tonbo Imaging, Bonfiglioli Transmissions, Sahajanand Medical, Zetwerk and Shellz India — and Core4 Engineers' ₹54.82 crore BSE SME IPO opens. Jio's grey market premium holds at ₹240 (~21.5%) on its final day, while Tonbo Imaging commands the strongest pre-listing GMP of the debutants at ₹438–516 (~63–74%).
Note: GMP is unofficial, unregulated and self-reported by grey-market dealers — it reflects market sentiment, not a guaranteed listing price. Tracker quotes differ, so ranges are shown where sources disagree.
Listing-day GMP: 5 IPOs debut today
All five debutants closed on 19 October; their shares begin trading on BSE and NSE today (Shellz on BSE SME). Latest available tracker quotes (23 October morning):
| IPO | Issue price | GMP (unofficial) | Implied listing | Final subscription |
|---|---|---|---|---|
| Tonbo Imaging | ₹700 | ₹438–516 (~63–74%) | ~₹1,138–1,216 | 135.90x |
| Bonfiglioli Transmissions | ₹586 | ₹60–178 (~10–30%) | ~₹646–764 | 46.06x |

| Shellz India (SME) | ₹179 | ₹5 (~2.8%) | ~₹184 | 58.54x |
Tonbo Imaging is the standout — the ₹852.18 crore defence-electronics OFS was subscribed 135.90 times, and tracker GMP implies the strongest debut of the five. Bonfiglioli's GMP varies widely across trackers (₹60–178), so treat its implied range with caution. Zetwerk's ₹5,012.33 crore issue, subscribed 3.06 times (QIB 4.73x, NII 1.40x, retail 0.73x), is priced for a flat listing near ₹151–152, with grey-market demand having collapsed from earlier highs. See our 5-IPOs listing-day preview for the full setup, and Tonbo's allotment recap for subscription detail.

FAQs
What is GMP (grey market premium)?
GMP is the unofficial price at which IPO shares trade among dealers before listing, over and above the issue price. It is unregulated, self-reported and can change quickly — it signals sentiment but does not guarantee the listing price.
Why do GMP numbers differ across trackers?
Different dealer networks, quote timings and sample sizes. This article shows ranges (e.g. Bonfiglioli ₹60–178 across marketframe, upcomingipo and ipowatch) where sources disagree rather than picking one number.
When does the Jio IPO close?
Today, 23 October 2026. The UPI mandate cut-off is 7:00 PM IST. Allotment is on 26 October and listing is expected on 28 October on BSE and NSE.
What is the Jio IPO GMP today?

Shares typically begin trading after the opening session around 10:00 AM IST, following the pre-open call auction (9:00–9:45 AM) on the listing exchanges.
Conclusion
Today is a rare double event: the close of India's biggest IPO ever and five simultaneous listings. Jio's ₹240 GMP suggests a healthy ~21% pop if sentiment holds into 28 October, while Tonbo's ₹438–516 GMP sets up the day's most-watched debut. The day's risk marker is Zetwerk — a flat GMP on a ₹5,012 crore issue, where listing-day trading will be decided by institutional absorption, not grey-market hype. We'll cover the debuts in the evening slot.
