Data Centre and AI Infrastructure Stocks in India: Assessing the Next Big Theme

In a single week in early 2026, roughly ten Indian companies loosely tied to data centres and AI infrastructure added a combined USD 1 billion in market value. The trigger was not an earnings beat or an order win. It was a New Delhi event attended by OpenAI's Sam Altman and Anthropic's Dario Amodei.

That reaction captures this theme in miniature: a real, structural build out of physical capacity, colliding with a genuine scarcity of ways to invest in it directly on the Indian stock market.

India's data centre capacity is expanding fast off a low base, the government has just backed the sector with one of the more generous tax packages in recent budgets, and global AI labs are name checking India as a market worth showing up for.

None of that automatically means the listed stocks currently rallying on this theme are the right vehicle for it. The absence of a clean, pure play, listed data centre operator means most of the money chasing this story is flowing into companies for whom data centres are one part of a much larger business, not the whole of it.

India's operational data centre capacity has grown from around 350 MW in 2019 to roughly 1,030 MW in 2024, crossing an estimated 1,300 MW by the end of 2025. Industry projections put capacity at around 1.7 GW by the end of 2026 and close to 1,825 MW by 2027, with government linked estimates suggesting a four to five times increase by 2030.

Mumbai alone accounts for roughly 50 to 55% of current capacity, helped by submarine cable landings and proximity to financial services clients, with Pune and Chennai the next largest hubs and Hyderabad and the Noida region growing quickly on cheaper land.

Period	Installed Capacity
2019	Around 350 MW
2024	Around 1,030 MW
End of 2025	Crossed roughly 1,300 MW
End of 2026 (projected)	Around 1.7 GW
2027 (projected)	Close to 1,825 MW

The scale of the runway is easiest to see by comparison. The United States runs more than 10,000 MW of data centre capacity today. India's entire projected 2026 base would still be a small fraction of that, which is precisely the case for a long build out cycle ahead, and precisely why the theme has attracted so much attention despite the current base still being modest in global terms.

Most of India's largest data centre operators, including Nxtra Data, Yotta and CtrlS, are not publicly listed. The closest a retail investor currently gets to direct listed exposure is Adani Enterprises, through its AdaniConneX joint venture, and even that is one division within a large, diversified conglomerate. Nxtra Data, Bharti Airtel's data centre arm, has filed a draft prospectus with SEBI, and once listed would likely be the closest India has offered to a genuine pure play, but no listing date has been confirmed.

In the meantime, investor enthusiasm for the theme has concentrated in engineering and construction firms, power and renewables names, cooling and precision hardware suppliers, and cloud or GPU infrastructure providers, none of which are data centre companies in the way a listed operator or REIT would be.

Brokerage Bernstein identified Larsen & Toubro as a direct beneficiary of the data centre build out, given its engineering, procurement and construction role in building the facilities and associated power infrastructure, alongside citing roughly USD 17 billion in announced data centre investment across India excluding Reliance.

Smaller, more specialised names have also drawn attention on the same theme: E2E Networks, a cloud infrastructure provider built around Nvidia GPUs, and Netweb Technologies, which manufactures supercomputing systems, both reportedly rose more than 18% within a single week during one such rally, alongside gains in Aurionpro Solutions and Techno Electric & Engineering.

Data centres are extremely power hungry, and that demand ripples outward to companies with no direct data centre business at all. Bernstein framed NTPC as an indirect beneficiary, since rising data centre power demand could affect coal plant retirement timelines and utilisation rates across the grid.

Adani Green Energy was framed similarly, as a likely supplier of renewable power paired with storage for data centre operators seeking reliable, sustainable electricity, with nuclear power flagged as a longer term possibility for the sector once current capacity additions mature.

Union Budget 2026 to 2027 introduced a specific tax incentive package for the sector, including a proposed tax holiday running until 2047 for eligible foreign cloud service companies using Indian data centre services for customers outside India, alongside a 15% safe harbour on cost where the Indian data centre service provider is a related entity, intended to give multinational groups tax certainty on intra group arrangements.

The Finance Bill 2026 formally defined data centre, data centre services and specified data centre for the first time, with these provisions taking effect from April 1, 2026. Data centres have also been classified as critical infrastructure, unlocking financing benefits, and several states, including Maharashtra, Tamil Nadu and Uttar Pradesh, run their own supportive state level policies.

Measure	What It Does
Tax holiday to 2047	For eligible foreign cloud service companies using Indian data centre services for customers outside India
15% safe harbour	Reduces tax uncertainty on cost charged between related entities within a group
Formal legal definitions	Finance Bill 2026 defines data centre, data centre services and specified data centre, effective April 1, 2026
Critical infrastructure status	Improves access to infrastructure linked financing for qualifying projects

Separate from the physical build out, India's broader AI industry is itself forecast to exceed USD 7 billion by the end of 2026 and grow toward USD 35 billion by 2032, with the country ranked first globally in AI skills penetration and close to nine in ten new startups incorporating AI in some form.

The government's IndiaAI Mission, backed by a Rs 7,500 crore allocation including the AIRAWAT cloud computing platform, is explicitly designed to build out data centres, GPU capacity and applications together, treating physical infrastructure and the software layer running on it as a single connected initiative rather than two separate stories.

Listed engineering and IT services firms including LTTS and Persistent Systems have positioned themselves around this layer, through GPU partnerships, generative AI service lines and hyperscaler alliances, though for most of these companies AI focused revenue remains one growth line within a much larger, diversified business.

Several risks sit underneath the enthusiasm. Global supply chains for semiconductors, servers, networking equipment and cooling systems remain exposed to geopolitical tension, and export restrictions between major economies could disrupt component availability for Indian projects.

Data centre operators typically depend on a concentrated set of hyperscaler and enterprise clients, so losing a single large customer, or a client shifting capacity in house, can meaningfully affect earnings for a smaller supplier. Financing costs matter more than usual here too, since these are capital intensive, debt funded projects sensitive to interest rates.

Perhaps the most specific risk is one built into the theme's own structure: because so much of the rally has run through proxies rather than pure plays, some of these stocks have already been sharply rerated on sentiment and news flow well ahead of any confirmed increase in their actual data centre related revenue.

A scarcity of pure plays does not make the proxies safe. It just means the enthusiasm has nowhere more direct to go.

A few practical conclusions follow from how thin and proxy driven this listed universe currently is:

• Separate direct beneficiaries, companies actually building or operating data centres, from indirect ones riding higher power demand, and from AI software names whose exposure is largely narrative rather than a large, disclosed revenue line.

• Check what share of a company's actual revenue comes from data centre or AI infrastructure work before assuming its stock price move reflects that business specifically, rather than a broader sector wide rerating.

• Watch for the Nxtra Data listing, and any other data centre operator IPOs that follow, as the first genuinely close to pure play way to invest in Indian data centre capacity directly.

• Treat sharp, news driven rallies, such as the reaction to a single high profile event, as a sign of thin, sentiment sensitive positioning rather than confirmation of a company's underlying fundamentals having changed that week.

• Remember that this is a capital intensive, long payback infrastructure theme at its core, sensitive to interest rates and financing costs, not a fast growing software story, even where AI provides the headline.

India has almost no listed way to buy the data centre itself. What is listed is everything the data centre needs to get built.
