Where can I find the subscription figure of an IPO?

IPO Subscription are made available to public on stock exchanges website on almost real time basis. Please visit the IPO section of exchange's website to get the detail. Note that each exchange shows only the data for bid received by themselves on real time. You can add the two (BSE and NSE Data) to get the figures at any time during the day. Total figures (combined bidding status from BSE and NSE) at the end of a day are however displayed directly on these sites at around 5 PM.
