In a historic corporate realignment, Bharti Airtel has eclipsed Tata Consultancy Services (TCS) to become India’s third-most valuable listed company by market capitalization. As of July 21, 2025, the telecom giant’s market value surged to ₹11.44–11.45 lakh crore, narrowly surpassing TCS’s ₹11.42–11.43 lakh crore—a margin of ₹2,000–₹2,220 crore . Reliance Industries (₹19.3 lakh crore) and HDFC Bank (₹15.34 lakh crore) retain the top two positions .
The Turning Point: Market Dynamics
- Stock Trajectories: Airtel’s shares soared 20.2% year-to-date in 2025, adding nearly ₹2 lakh crore to its market cap—the second-largest gain in the Nifty50 after Reliance. Conversely, TCS witnessed a 22% decline, eroding ₹3.4 lakh crore from its value amid global IT sector headwinds .
- Sectoral Shift: This reversal underscores a broader trend: telecom’s resurgence versus IT’s stagnation. While Airtel leveraged India’s digital consumption boom, TCS grappled with weak U.S. demand and AI-driven disruptions .
