Microsoft to invest $17.5bn in India to build AI infrastructure: CEO Nadella

Microsoft will invest $17.5 billion in India over the next four years to accelerate the country’s transition to an AI-first economy, chief executive Satya Nadella said on Tuesday.

The commitment, described by Microsoft as its largest investment in Asia, follows Nadella’s meeting with Prime Minister Narendra Modi in New Delhi, where both leaders discussed India’s artificial intelligence roadmap and long-term growth priorities. Reuters reported that Nadella framed the investment as central to building the infrastructure, skills and sovereign capabilities required for nationwide AI adoption.

In a post on X, Nadella thanked the prime minister for “an inspiring conversation on India’s AI opportunity,” adding that the $17.5 billion outlay would support cloud capacity, talent development and secure digital infrastructure.

Microsoft said the investment would run from calendar year 2026 through 2029 and rests on three pillars — scale, skills and sovereignty — aligning with the government’s ambition to build an integrated ecosystem for AI innovation. The announcement marks a sharp escalation from the company’s $3 billion pledge in January to bolster cloud and AI infrastructure in India, including new data centres.

Nadella said the new commitment would support Microsoft’s existing workforce of more than 22,000 employees across Bengaluru, Hyderabad, Pune, Gurugram, Noida and other cities. He noted their role in the full product cycle, from model development and engineering to operating hyperscale data centres and delivering sales and support nationwide.

Microsoft highlighted that these India-based teams contribute to major global AI programmes, including Copilot Studio, Azure AI Search, AI agents, speech and translation models, and Azure Machine Learning.

A key component of the investment is the development of sovereign-ready cloud infrastructure. The company cited “significant progress” on its India South Central cloud region in Hyderabad, due to go live in mid-2026. It said the facility will be its largest hyperscale region in India, spanning three availability zones and approximately equivalent in size to two Eden Gardens stadiums.

Microsoft will also expand its existing data centre regions in Chennai, Hyderabad and Pune to offer organisations greater resilience and lower latency for mission-critical operations. It said the broader network will support enterprises, start-ups and public sector agencies seeking to adopt advanced AI capabilities.

The investment signals the intensifying battle among global technology firms to anchor themselves in India’s rapidly scaling digital economy. Analysts expect that Microsoft’s move will sharpen competition with rivals investing in data infrastructure and AI research in the region. Further details on execution timelines and sector partnerships are likely to emerge as the company advances its India strategy through 2026.
