Tata Communications Commits $450 Million to Build AI Super Highway Across India

Tata Communications has unveiled plans to invest approximately $450 million (roughly ₹4,350 crore) to construct an "AI Super Highway" designed to interlink India's rapidly expanding artificial intelligence and cloud data centre corridors. The ambitious infrastructure rollout entails deploying around 10,000 kilometres of new long-haul and metro terrestrial fibre across the country over a three- to five-year timeline.

The company disclosed the development in an exchange filing on October 26, noting that the project will be financed entirely through operating cash flows. Tata Communications is targeting a 30% to 40% market share in the domestic data centre-to-data centre (DC-to-DC) interconnect market, which management projects will expand into an opportunity exceeding $1 billion over the medium term. Following the announcement, Tata Communications shares gained 1.73% to trade at ₹1,683 on the NSE.

Three-Phase Network Rollout

The high-capacity digital corridor will be developed across three strategic phases to match projected workload demand and pipeline capacity additions:

• Phase 1: The initial phase will interconnect primary digital hubs across the Mumbai–Pune–Hyderabad–Chennai corridor.
• Phase 2: The second leg will expand along the eastern coast, connecting Chennai, Hyderabad, and Visakhapatnam.
• Phase 3: The concluding phase will stretch toward eastern and western nodes, including Bhubaneswar, Jamnagar, and Gujarat International Finance Tec-City (GIFT City).

The new fibre routes will integrate seamlessly into Tata Communications' existing infrastructure, which currently encompasses over 500,000 kilometres of subsea optical fibre, 200,000 kilometres of global terrestrial fibre, and an India terrestrial footprint exceeding 80,000 kilometres connected to 118 domestic data centres.

Massive Network Capacity Boost

The AI Super Highway is engineered to add approximately 6 petabits per second (Pbps) to Tata Communications' current domestic network capacity of 1.25 Pbps. The incremental bandwidth—designed to support ultra-low-latency workloads, large-scale model training, and inferencing—is scheduled to come online between FY2030 and FY2036.

Managing Director and CEO Ganesh Lakshminarayanan highlighted that the surge in artificial intelligence adoption, data localisation mandates, and cloud migrations has created unprecedented demand for resilient, high-speed inter-facility transport. The network is slated to cater primarily to global hyperscalers, neo-cloud providers, Global Capability Centres (GCCs), and enterprise banking institutions.

Investor Takeaways and Capital Efficiency

India’s operational data centre footprint reached nearly 1.8 GW in the first half of 2026, with an additional 3.86 GW in development or pipeline stages through 2030, according to industry estimates. By building dedicated, carrier-neutral interconnect lines, Tata Communications aims to establish critical backbone infrastructure ahead of hyperscaler expansion.

The company expects a 15% to 20% return on investment benchmark for the capital outlay, monetising incremental capacity as individual phases go live. With anchor clients already engaged and zero reliance on external debt financing, the capital allocation plan is expected to keep the company's balance sheet intact while building multi-year revenue visibility in high-margin enterprise data services.
