The IPO Calendar tracks every scheduled IPO event in India — covering both Mainboard issues (listing on BSE / NSE) and SME issues (listing on BSE SME / NSE Emerge). For each IPO you'll see four key dates: the opening date (when bidding starts), the closing date (last day to apply), the allotment date (when the registrar finalises share distribution), and the listing date (when shares begin trading on the exchanges). Events are colour-coded — green for opening, orange for closing, purple for allotment, blue for listing — so you can scan a month at a glance and never miss an application deadline.

IPO Timeline Explained — From Bid to Listing

An Indian IPO follows a roughly 7-day timeline once it opens. Here's what happens at each stage:

Day T−1 (Anchor allocation): Anchor investors (mutual funds, FIIs, insurance companies) bid one day before the public issue opens, taking up to 60% of the QIB portion.
Day T (Open): Public issue opens for retail, NII, and remaining QIB bids. Application via UPI or ASBA.
Day T+2 to T+3 (Close): Bidding window closes. Most Mainboard issues run for 3 working days; SME issues sometimes run for 5.
Day T+5 to T+6 (Allotment): Registrar finalises the basis of allotment. Successful applicants see shares credited to their demat account; unsuccessful applicants get refunds (or UPI mandates released).
Day T+6 to T+7 (Listing): Shares begin trading on the exchange. Listing-day price discovery happens during a special pre-open session, then continuous trading.

SEBI has been steadily compressing this timeline — the goal is "T+3 listing" (listing 3 working days after issue close), and many recent IPOs have moved to that schedule. The calendar above reflects the actual announced dates for each IPO.

Why Some IPO Dates Shift

IPO dates can change after initial announcement for several reasons. SEBI observations on the DRHP (Draft Red Herring Prospectus) may require the company to file a revised version. Market conditions sometimes prompt promoters or merchant bankers to delay launch — for example, a sharp Nifty fall in the week before the planned open often pushes IPOs back. Regulatory clearances from RBI (for financial services issues) or sector-specific bodies can take additional time. Less commonly, book-building issues (insufficient demand or pricing concerns) can lead to deferral.
