New Delhi, Feb. 20 -- Days after the Adani Group announced a mammoth $100 billion plan for AI-ready data centres and power, fellow conglomerate Reliance Industries fired another salvo on Thursday with a $110 billion (Rs.10 trillion) bet to build India's sovereign artificial intelligence (AI) backbone. The money would be invested over seven years by RIL and Jio Platforms (its digital business), Reliance Industries chairman Mukesh Ambani said on the fourth day of the India AI Impact Summit 2026 in New Delhi. Alongside, Tata Sons chairman N. Chandrasekaran announced at the same event that Tata Consultancy Services (TCS) has signed up American AI giant OpenAI as the anchor client for its upcoming data centre. The two companies will collaborate to develop secure, India-based AI infrastructure aimed at strengthening data sovereignty and long-term compute capacity. Ambani said RIL and Jio would build what he described as India's sovereign compute infrastructure, including multi-gigawatt (GW) AI-ready data centres at Jamnagar, green energy-backed capacity, and a nationwide edge network to make AI affordable and widely accessible. "India cannot afford to rent intelligence. Therefore, we will reduce the cost of intelligence as dramatically as we did the cost of data," Ambani said in his address at the summit, adding that "an edge-compute layer, deeply integrated with Jio's network, will make intelligence responsive, low-latency and affordable-close to where Indians live, learn and work". Shares of RIL closed 2.4% lower at Rs.1,407.2 on the National Stock Exchange on Thursday. The company is looking to bring up about 120MW (megawatt) data centre capacity in the second half of 2026 to support high-scale compute for training and large-scale inference of AI systems. The company is currently preparing to file draft papers for listing Jio Platforms on the exchanges. Meanwhile, Tata Sons' Chandrasekaran said the collaboration with OpenAI was milestone in India's vision to become a global leader in AI. "Together, we will skill India's youth and empower them to succeed in the AI era," Chandrasekaran said....
