IPO GMP Today (1 Nov): BLS Polymers at 45% Before Listing
The primary market heads into a busy week, and the grey market has already picked its favourite. BLS Polymers is commanding a premium of roughly 45% ahead of its 3 November listing, far ahead of the other issues lined up for debut. EAAA India Alternatives, meanwhile, lists tomorrow (2 November) with a modest premium of around 3%. Here is the full picture for Sunday, 1 November 2026 — today's grey market premiums, the IPOs still open for subscription, and the key dates for the week ahead.
Important: Grey market premium (GMP) is unofficial, market-reported data from an unregulated market. It is not published or recognised by SEBI, NSE or BSE, it varies across dealers and locations, and it can change quickly. It is a sentiment indicator only — never a guarantee of the listing price.

BLS Polymers: the week's standout
BLS Polymers is the clear grey-market leader. The ₹255 crore mainboard IPO, which closed on 29 October, was subscribed a massive 241.22 times, and the grey market is now pricing it at ₹68–73 over its ₹150 upper-band price — an estimated listing price of roughly ₹218–223. That kind of premium, backed by genuine subscription demand rather than thin grey-market chatter, makes it the debut to watch on Tuesday, 3 November.
SFC Environmental Technologies, which lists the same day, tells a quieter story: a 9.47 times subscription and a GMP of just ₹20–21 (~6%) over its ₹330 issue price, pointing to a modest listing around ₹350–351.
EAAA lists tomorrow at a modest premium
EAAA India Alternatives makes its stock market debut on Monday, 2 November, on the NSE and BSE. The ₹1,200 crore issue was entirely an offer for sale by the Edelweiss Group and was subscribed 5.25 times. With a GMP of ₹52–56 over its ₹1,665 final price, the grey market is pricing a flat-to-modest debut at roughly ₹1,717–1,721. Allotment for the issue was finalised on 29 October.

Conclusion
Sunday's grey market is a two-speed story: BLS Polymers heads into its Tuesday listing with a commanding ~45% premium and a 241 times subscription behind it, while EAAA, SFC and M.K. Sons all point to modest single-digit debuts. Monday brings the first test with EAAA's listing and M.K. Sons' allotment, plus the final day of bidding for Bombay Coated.
