Primary Data Sources

National Stock Exchange (NSE)

Website: nseindia.com
Coverage: Mainboard, SME and DEBT IPOs listed on NSE
Update Frequency: Near real-time

Bombay Stock Exchange (BSE)

The BSE data source is in public beta starting 2nd January, 2026. What this means is:

We have developed pipelines to aggregate data from BSE's publicly announced IPOs. These pipelines will attempt to make this data available in the API.
This does not guarantee any form of accuracy, reliability, consistency or that IPOs from BSE will always be available.
All IPO objects that are sourced from BSE will have a field source with the value set to "bse". Similarly, all IPO objects that are sourced from NSE will have the source value set to "nse". All existing IPOs remain unchanged.
We will work towards improving these pipelines over the next few weeks to ensure better quality. If you find any issue with the data or its accuracy, please reach out to support@ipoalerts.in and we will look into it.
