India’s Biggest Mega Issue: Mukesh Ambani's Jio IPO Likely Opening on October 21
Indian capital markets are bracing for the largest initial share sale in domestic history as Mukesh Ambani-led Reliance Industries readies the stock market debut of its digital and telecommunications subsidiary, Jio Platforms Ltd. Having secured formal regulatory clearance from the Securities and Exchange Board of India (SEBI) on August 28, the retail subscription window for the public offer is anticipated to open from October 21 to October 23, 2026. Institutional anchor book allocations are scheduled to open on October 19, with the stock expected to debut on the bourses on October 28, subject to secondary market volatility and global macroeconomic conditions.
Record ₹37,700 Crore Issue Poised to Eclipsing Historical Market Milestones
While corporate headquarters have withheld formal notification of the final price band, market projections place the headline issue size at an unprecedented ₹37,700 crore. At this valuation, the offering will decisively overtake Hyundai Motor India’s ₹27,858.75 crore listing to claim the crown as the largest public issue ever recorded on Indian stock exchanges. Pre-IPO institutional roadshows have met with robust appetite across foreign institutional investors (FIIs) and domestic asset managers, reflecting confidence in the telecom juggernaut’s 5G rollout, digital cloud ecosystem, and expanding subscriber base.

Strategic Debt Deleveraging: ₹27,500 Crore Earmarked for Reliance Jio Infocomm
In alignment with the Draft Red Herring Prospectus (DRHP) submitted to market watchdogs, Jio Platforms intends to channel roughly ₹27,500 crore of the net fresh capital proceeds directly into retiring or prepaying long-term debt liabilities carried by its primary telecom operating arm, Reliance Jio Infocomm Ltd (RJIL). This targeted balance-sheet deleveraging will significantly trim debt-servicing outlays, enhance operating free cash flows, and sharpen return-on-equity metrics. The remaining capital will support general corporate objectives, underwriting the digital giant's ambitious expansions across cloud computing, artificial intelligence infrastructure, and next-generation connectivity across urban and rural India.
