Mumbai is set to retain its position as India’s dominant data-centre market even as new facilities spread to secondary hubs, according to CII-CBRE data. The city’s share of installed data-centre capacity across India’s tier-I markets is estimated to rise from 52 per cent in H1 2026 to 68 per cent by 2030.
Mumbai’s installed data-centre capacity is expected to grow 2.1 times, from 0.9 GW in H1 2026 to more than 2 GW by 2030, driven by demand from financial institutions, cloud-service providers, government bodies and defence entities. Artificial intelligence workloads are adding a further layer of demand, shifting the market toward GPU-focused deployments and captive enterprise capacity beyond conventional hyperscale cloud and colocation facilities.
According to the report, Mumbai’s advantages include power infrastructure, fibre connectivity, limited natural-hazard exposure and subsea cable terminations. The geography of expansion is moving beyond Mumbai’s traditional commercial core, with Chandivali and Navi Mumbai — particularly the Thane–Belapur corridor and areas around Panvel — identified as leading growth areas due to larger land parcels and power availability.
Anshuman Magazine, Chairman and CEO for India, South-East Asia, Middle East and Africa at CBRE, said investment commitments toward data centres stood at around $38 billion in H1 2026, describing the capital commitment as unusually strong and noting that AI-linked investment is changing what is being built.
India added 130 MW of new data-centre supply in H1 2026, an 18 per cent year-on-year increase, with domestic operators accounting for 50 per cent of new supply and the remainder split among operators from Europe, the Middle East, Africa and the Americas. While secondary hubs are expected to grow, the CII-CBRE assessment indicates this diversification will not displace Mumbai’s market leadership within the decade.
