Backed by official regulatory filings and corporate disclosures, the National Stock Exchange of India has adjusted its initial public offering parameters, cutting its offer-for-sale size to 126.4 million shares and setting anchor bidding for September 16.

Advancing toward one of the most anticipated market debuts in global financial history, the National Stock Exchange of India (NSE) officially updated its draft red herring prospectus documents, modifying key structural terms of its landmark public offering. According to official exchange filings released on September 10, 2026, the aggregate offer-for-sale (OFS) size has been trimmed from the previously estimated 148.9 million shares down to up to 126.4 million equity shares. Institutional anchor investors are slated to submit their preliminary bids on September 16, 2026, setting the stage for the primary public subscription window to open across the country.
