State Bank of India (SBI) is positioned to secure one of the most lucrative windfalls in recent years, as the National Stock Exchange (NSE)’s much-awaited mega Rs 30,000 crore IPO will monetise decades of patient capital with an astronomical 256,775% profit for the country’s largest lender. The proposed Rs 30,000 crore issue, which is structured entirely as an offer for sale (OFS) of up to 148.9 million shares representing nearly 6% of NSE's paid-up capital, is poised to become the largest-ever IPO in India. It eclipses the Rs 27,000 crore record held by Hyundai Motor India's 2024 listing, though Reliance Industries Ltd.'s Jio is also planning an IPO that could be larger but has yet to file papers. Because regulations prohibit a stock exchange from self-listing, the NSE will be listed on rival BSE.
