The global rush to build artificial intelligence infrastructure is creating a wave of capital expenditure in India, with a group of domestic companies providing essential data center services emerging as the quiet winners. According to compiled data, an index tracking 28 such Indian firms has seen its collective market value swell by approximately $47 billion this year, representing a gain close to 50%.
Sterlite Technologies, a fiber optic manufacturer, stands as the most significant beneficiary of this surge. Its share price has rocketed more than 500% year-to-date, with a staggering 270% of that gain occurring in just the past 43 trading sessions. The immediate catalyst for this explosive move was a multi-year, $1.1 billion contract awarded last month from a major U.S. hyperscale data center client. Other companies in the ecosystem have also seen massive gains, with rival HFCL up 191% this year and precision cooling component maker MTAR Technologies rising over 200%.
Market Dynamics and the AI Capex Trade
This AI infrastructure investment frenzy is reshaping the landscape of the Indian stock market. The spectacular rallies in companies like Sterlite present a stark contrast to the broader market, where the benchmark NSE Nifty 500 index has shed over $300 billion in value during 2026. This divergence has led the market to label the trend the "AI capital expenditure trade." The logic is that because every AI query must be processed by power-hungry data centers, traditional industrial companies supplying the physical infrastructure have unexpectedly become some of the hottest investment targets.
Government Policy and Major Investments
The development of AI infrastructure in India is receiving robust support at the policy level. In the initial budget for the 2026-27 fiscal year, the government proposed tax incentives lasting until 2047 for foreign companies that use Indian data centers to provide cloud services to global clients. In a significant recent development, Australian data center giant AirTrunk announced plans to invest 3 trillion rupees to develop 5 gigawatts of data center capacity in India, a move personally welcomed by Prime Minister Narendra Modi.
Analyst Perspective and Valuation Concerns
A research analyst from Valentine Advisory noted that the stunning rallies in these previously overlooked beneficiary companies stem from a growing market conviction that AI is initiating a multi-year infrastructure capital expenditure cycle, rather than being merely a software opportunity. However, with Sterlite currently trading at a price-to-earnings ratio of around 70 times—significantly above the NSE 500 index average of 19 times—the risks associated with overheated valuations cannot be ignored.
