IPO details
From calendar to cash
This calendar answers "when". The calculator answers "how much". Pair them: pick an IPO here, jump to the calculator, enter your lots + expected oversubscription, and see your probability and margin ROI before the subscription window closes.
This calendar shows the deals. It does not show how they were allocated.
The tracker lists what is open for subscription right now. The Pro HK IPO allocation desk carries 681+ deals of full history — oversubscription multiple, cornerstone share, grey market read and each sponsor’s debut-break record — so you can check how comparable deals actually allotted before you apply.

How often is this calendar updated?▾
Twice daily at 11:00 and 22:00 Hong Kong time. A cron job on our VPS scrapes AAStocks, diffs the JSON, and triggers an incremental revalidate. In practice you will see same-day changes within an hour of AAStocks publishing them.
What do the stage codes mean?▾
O = Subscription opens · P = Subscription period · C = Subscription closes · F = Offer price fixed · A = Allotment announced · L = Listing day on HKEX. Two derived codes: R = Refund (allotment date − 1, afternoon) when unallocated capital actually returns to your account, G = Grey market (listing date − 1, evening) when you can trade on the off-exchange venue before official listing.
How do I tell when my capital is free for the next IPO?▾
Official allotment date (A) is when the exchange publishes results, but most brokers SMS/push the outcome the afternoon BEFORE, which is when unallocated cash is already usable. Rule of thumb: if IPO B's subscription_close date is on or after IPO A's (allotment − 1), you can roll the same capital from A into B. The 'Capital-compatible combos' cards above do this check for you.
What happens at grey market?▾
Grey market is the off-exchange trading window on the evening before official HKEX listing (typically 16:15 – 18:30 HKT on L − 1). Brokers like Phillip / Futu let you enter trades at expected open prices, useful for locking in gains / cutting losses before the 09:00 listing session.
How do I estimate my allotment probability?▾
Click "Estimate allotment" on any IPO card. Our free calculator uses the dual-pool model (Pool A retail, Pool B large) calibrated against real HKEX allotment data. Enter your lots + expected oversubscription, get probability + margin-financed return.
