The National Stock Exchange (NSE) is expected to file its IPO draft prospectus this week, according to reports. Ahead of the potential listing, unlisted NSE shares are reportedly trading above Rs 2,000 on several major platforms, with price-to-earnings multiples around 50. The company’s valuation has been cited at more than Rs 5 lakh crore based on current market indications for its unlisted equity. Several sources link the prospective listing to a stronger position for NSE within India’s benchmark Nifty index, suggesting that an IPO could increase the bourse’s market prominence and index weighting. The reporting indicates that the IPO process is at the stage of preparing and filing draft documents, with the eventual listing expected to take place later subject to regulatory approvals and market conditions. No additional deal size, offer structure, or expected listing date is provided in the excerpts, and the figures on trading and valuation refer to prevailing sentiment and pricing in the unlisted-share market prior to the formal IPO filing.
