IPO Bulletin is an independent website tracking Indian primary-market activity: Mainboard and SME IPOs, grey market premium (GMP), subscription status, listing-day performance, and related news — built for retail investors who want the same real-time picture professional desks work from, in one place.
What this site does
Every IPO currently open, upcoming, or recently listed is tracked automatically: price bands, bidding windows, subscription multiples, GMP, and since-listing returns. Nothing here requires manual updating day to day — the data refreshes itself on a schedule, and pages like Recently Listed or GMP Updates update as issues move through their lifecycle.
How the data is sourced — full transparency
We believe a site built on financial data owes its readers a clear account of where that data actually comes from, so here it is in full:
- IPO facts, dates and GMP figures are pulled from free, publicly available data projects (community-maintained scrapers of NSE, BSE and grey-market tracking sites, hosted on GitHub) and, where configured, the IPO Guru API.
- Market indices, stock quotes and cryptocurrency prices come from Yahoo Finance’s public quote data.
- The GIFT Nifty quote in the top bar is a live widget from TradingView, showing their real-time data directly — we don’t process or store it ourselves.
- News headlines are pulled from the public RSS feeds that outlets such as Economic Times, Reuters and The Hindu publish specifically for this kind of use, always linking back to the original article with full attribution.
- IPO allotment status is checked directly on BSE’s official public portal — we never store or process your PAN or application number ourselves.
None of these sources are official exchange feeds, and none of them are guaranteed to be perfectly accurate or up to the second. Grey Market Premium in particular is unofficial, unregulated sentiment — not a number published or endorsed by SEBI, NSE or BSE. Where we don’t have a genuine data source for something, we say so on the page rather than showing an invented number — you will see that disclosure on several sections of this site.
Built with AI assistance
In the interest of full transparency: this website’s theme, layout and much of its data-integration code were built with the help of Claude, an AI assistant made by Anthropic, working directly with the site owner. AI assistance was used for development and design — the data shown on the site itself, however, is pulled live from the real sources listed above, not generated or estimated by AI. If that ever changes for any specific feature, we’ll disclose it plainly on that feature.
Not investment advice
Nothing on this site is investment, legal or tax advice. Read the official Red Herring Prospectus (RHP) for any IPO you’re considering, and speak with a SEBI-registered investment adviser before making investment decisions. See our Disclaimer and Risk Disclosure pages for the full detail.
