Tata Communications Plans $450 Million AI Super Highway in India

Tata Communications’ AI Super Highway investment will commit up to $450 million over the next three to five years to build approximately 10,000 kilometres of AI-ready fibre infrastructure connecting India’s major data-centre and artificial intelligence hubs. The project aims to provide high-speed, low-latency connectivity as demand grows for moving large volumes of data between computing facilities.

Announced on October 26, 2026, the planned investment is expected to range from $400 million to $450 million. The network will be integrated with Tata Communications’ global backbone and is designed to serve hyperscalers, cloud providers, AI developers, large enterprises and other businesses requiring high-capacity connectivity.

AI Super Highway Investment Targets India’s Data Centres

The planned network will connect key data-centre corridors through long-haul and metropolitan fibre infrastructure. Tata Communications says the network will offer approximately 7.2 petabytes of capacity to support bandwidth-intensive AI workloads and data-centre interconnection.

The first phase will connect Mumbai, Pune, Hyderabad and Chennai, a corridor containing important data-centre and hyperscale infrastructure hubs. Subsequent phases will extend connectivity towards the eastern coast and western India, including Visakhapatnam, Bhubaneswar, Gujarat and GIFT City.

The company also plans to connect domestic data-centre clusters with international cable landing stations and its global network. This could help businesses move data between Indian facilities and overseas AI infrastructure while providing alternative routes for international connectivity.

Why AI Workloads Need Faster Connectivity

AI infrastructure depends on more than processors and computing capacity. Data must also move efficiently between servers, data centres and other systems supporting model training and inference. Slow connections or insufficient bandwidth can create bottlenecks even when computing resources are available.

Tata Communications is positioning the network around these requirements, including higher bandwidth, low latency and network resilience. The company says customers increasingly require connections capable of supporting 400-gigabit and 800-gigabit speeds, with some requirements extending to terabit-scale connectivity.

The planned infrastructure is intended to support hyperscalers, neocloud providers, AI laboratories, software companies and enterprises deploying AI applications. Its performance will depend on how the network is engineered, how quickly capacity becomes operational and whether the service meets customer requirements.

Tata Communications Targets 30–40% Market Share

Tata Communications is targeting a 30–40% share of the data-centre-to-data-centre connectivity market it can address through the new network, according to comments by executive vice-president Rupesh Chokshi to Moneycontrol.

The company estimates that India’s data-centre connectivity market could exceed $1 billion over the medium term. That figure is a market projection, rather than current revenue generated by the new network. Tata Communications said it was in advanced discussions with potential customers but had not yet announced contracts specifically for the proposed AI Super Highway.

The investment is expected to be deployed in stages, with priorities determined by projected traffic, capacity requirements and the pace of data-centre development. Management has said that long-term customer contracts could support durable revenue as the infrastructure comes online.

Investment Builds on Tata Communications’ Existing Network

Tata Communications already operates more than 500,000 kilometres of subsea optical fibre and over 200,000 kilometres of terrestrial fibre. The new investment will expand its terrestrial connectivity while linking the network more closely with its international infrastructure.

The company is also pursuing subsea cable projects connecting Mumbai with Singapore and Chennai with Singapore. These initiatives are intended to complement domestic connectivity and provide additional routes to international markets.

The AI Super Highway represents a long-term infrastructure bet on India’s expanding cloud and AI sectors. Its commercial success will depend on customer commitments, the pace of deployment and whether demand grows enough to justify the investment.
