Indian Stock's 530% Rally Highlights Hidden AI Investment Opportunities

India's AI Boom: Unseen Winners Emerge Amid Global Market Woes

The Indian equity market's failure to capitalize on the global artificial intelligence boom has been a narrative that has dominated headlines. However, a closer examination reveals a different story - one of smaller, under-the-radar firms reaping the benefits of the trillions of dollars being invested in AI capacity.

At the forefront of this rally is Sterlite Technologies Ltd., an optical-fiber maker owned by the Vedanta Group, which has surged a staggering 530% this year. The company recently secured a $1.1 billion multi-year contract from a US-based hyperscaler, cementing its position as a key beneficiary of the AI boom. Its competitors, HFCL Ltd. and MTAR Technologies Ltd., have also seen significant gains, with HFCL jumping 191% and MTAR more than trebling in value.

A closer look at the data reveals that an equal-weighted Bloomberg index of 28 Indian companies that feed the data-center ecosystem has added approximately $47 billion in combined market value this year, a rise of nearly 50%. In contrast, the benchmark NSE Nifty 500 has lost over $300 billion in 2026.

The connection between AI and the industrial sector is clear: every AI query runs through power-hungry data centers that require immense electricity and cooling. As a result, old-economy industrial firms have transformed into India's hottest market play, with the 'AI capex trade' becoming a buzzword in Mumbai dealing rooms.

According to R. Sivakumar, chief investment officer at Axis Mutual Fund, "We may be on the wrong end of the AI trade, but we could be on the right side of the AI capex trade." One possible approach is to consider companies benefiting from data centers and the entire value chain associated with this capex.

Large tech giants are also investing heavily in India's cloud infrastructure. Amazon.com Inc. plans to invest $12.7 billion in cloud infrastructure in India through 2030, while Alphabet Inc. is spending about $15 billion on an AI infrastructure hub in Visakhapatnam.

Nomura Holdings Inc. analysts, led by Akash Gupta, have identified the industrial supply chain as the most attractive exposure in this space, dubbed the 'picks and shovels' that build, power, and cool these facilities. Furthermore, a two-to-four year lead time in supplying some components has created an enviable seller's market with multi-year backlogs, according to Nomura analysts.

Foreign investors are already piling in, with shareholding of foreign funds in industrials rising to 14% as of end-March, the highest in two years, according to Elara Capital (India) Pvt. Even as global funds remain record sellers of Indian stocks, foreign investors are taking advantage of the opportunities presented by the AI boom.

The market is rewarding companies with visible AI-linked earnings rather than just thematic exposure, according to Angel One. However, the biggest near-term risk is valuation, as share rallies have left "no room for execution disappointments," the brokerage added.

For instance, Anant Raj Ltd., the only listed pure-play data center firm, has gained just about 8% this year. Meanwhile, Sterlite is trading at about 70 times its 12-month forward earnings, compared to NSE 500's 19 times.

Despite the risks, no market watcher is downplaying the opportunity presented by the AI boom. Nomura analysts have described data center capex as the single largest contemporary industrial investment cycle, larger than the global wireless 4G roll out, the post-2008 LNG build-out, or the early-2010s shale boom.
