Solving Information Asymmetry in Primary Capital Markets
The Indian primary capital market is experiencing an unprecedented surge in participation. With hundreds of companies listing on the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE) — alongside growing micro-cap enterprises on NSE Emerge and BSE SME — retail investors, High-Net-Worth Individuals (HNIs), and qualified institutional buyers require clean, timely, and verified data to make informed allocation decisions.
Historically, informal primary market indicators such as Grey Market Premium (GMP), Kostak rates, and Subject to Sauda contracts were restricted to closed informal circles, WhatsApp groups, and localized broker corridors in cities like Mumbai, Ahmedabad, Rajkot, Surat, Jaipur, and Delhi.
Grey Market Premium IPO was created with a singular objective: to bring absolute transparency, institutional-grade analytical rigor, and zero-bias reporting to every participant in the Indian stock market.
Real-Time Data Feeds
We update GMP figures, Kostak prices, and live bidding subscriptions multiple times throughout the trading day as market conditions shift.
Fundamental Breakdowns
Every IPO review includes deep breakdowns of Draft Red Herring Prospectus (DRHP) filings, financial ratios, peer valuations, and promoter checks.
100% Unbiased
We do not issue buy or sell tips, nor do we broker informal contracts. We deliver verifiable market data so you remain in control.
Our 4-Step Triangulated GMP Research Methodology
Our intelligence desk follows a structured multi-step verification pipeline before updating any Grey Market Premium figure.
Multi-City Dealer Network
We collect live bid and offer spreads from active over-the-counter (OTC) dealers in primary trading hubs across Ahmedabad, Mumbai, Rajkot, Surat, Jaipur, and Delhi.
Bid-Ask Volume Matching
A quote is only recorded if real transactional volume exists. Single-lot speculative quotes without committed counter-parties are discarded.
Outlier Rejection Filter
Our algorithms identify and filter out price manipulation attempts, artificial hype spikes, and operator-driven deviations.
Timestamped Publishing
Every GMP change is logged with a precise timestamp, calculated percentage return against the upper price band, and expected listing price projection.
