Jio Platforms' shares opened at ₹1,358, a 21.36% jump from the ₹1,119 issue price, valuing the company at ₹12.57 trillion overnight.
The first‑day rally made the digital‑services firm the second most valuable domestic company on the BSE and NSE, trailing only Reliance Industries’ own conglomerate.
The 21.36% premium on debut places Jio among the best‑performing IPOs in recent years, matching the high first‑day gains seen by other large‑cap listings in 2023.
Telecom sector saw a total market cap of ₹3.0 trillion last year, and Jio’s addition pushes the sector closer to a ₹5 trillion valuation by the end of 2026, according to sector analysts.
In its filing to the NSE, Jio disclosed a roadmap to roll out 5G services by Q4 2026 and to invest ₹4 trillion over the next three years, aiming to capture a larger share of the digital‑services market.
