With NSE filing Draft Red Herring Prospectus (DRHP) for its much-awaited IPO, the public issue of shares is set to gain limelight in the coming days since this will be the largest in terms of issue size in the Indian market. The 100% offer for sale (OFS) comprises 14.89 crore shares representing nearly 6% of the paid up capital. NSE shares will make their stock market debut on the competing exchange, the BSE, rather than self-listing on its own platform. The share sale is the first heavyweight IPO of 2026 with an issue size of Rs 30,000 crore.
