Global AI Boom: 4 Indian AI Stocks to Watch

#2 HFCL

Next on our list is the stock of HFCL.

HFCL has become one of India's major players in the optical fibre cable (OFC) industry and is increasingly positioning itself as a global high-capacity fibre solutions company rather than just a domestic telecom supplier.

Rising demand for optical fibre networks, telecom infrastructure and data-centre connectivity in India are positives for the company.

As global hyperscalers expand AI and cloud operations, large investments in fibre backhaul, high-speed networking and data-centre interconnections are expected.

HFCL has a presence in optical fibre cables, telecom equipment and networking solutions. The company is also expanding into defence communication systems.

HFCL Financial Snapshot

On the financial front, the company's revenues surged to Rs 18,241 in Q4 FY26 m vs Rs 8,007 m YoY. HFCL reported a sharp increase in net profits to Rs 1,852 m vs losses in the March quarter of the previous financial year.

Moving ahead, HFCL's expansion plans are progressing steadily. As highlighted in its investor presentation on 30 April 2026, the company is set to increase its Optical Fiber Cable (OFC) manufacturing capacity to 43 m fkm by June 2026.

It has already doubled its optical fiber production capacity from 14 m fkm to 28 m fkm, with an additional goal to reach 33.9 m fkm by December 2026.

Furthermore, HFCL's planned foray into preform manufacturing aims to enhance supply-chain security, boost cost efficiency, and support long-term margin growth.

In a noteworthy strategic initiative, the company has signed a Memorandum of Understanding (MoU) to explore opportunities in the defence aerospace sector.

In a recent presentation of 30 April 2026, the company has highlighted significant orders. The OF, OFC & connectivity solutions business has an order book of Rs 134.83 bn, while the defence equipment business has an order book of Rs 22.30 bn.

The EPC and system irrigation business has an order book of Rs 66.2 bn, while the telecom equipment business has an order of Rs 8.04 bn.

Overall, the prospects of the company seem bright. However, investors should note that the stock has doubled in the last one month.

#4 Cummins India

Last on our list is the stock of Cummins India.

Cummins India manufactures diesel and natural gas engines, power generators, and related components used across industries such as transportation, construction, manufacturing, healthcare, and data centers.

The company is a major supplier of backup power solutions through its gensets, which are widely used in commercial buildings and industrial facilities. It also provides after-sales service, maintenance, and spare parts through a large distribution network.

Data centers require uninterrupted electricity and backup power systems. Cummins India supplies high-capacity diesel and gas generator sets that act as emergency backup during grid failures.

As global technology companies and AI firms expand data center capacity in India, demand for reliable power infrastructure rises sharply.

It also provides long-term maintenance, spare parts, and servicing for these installations. Growth in hyperscale AI data centers, cloud computing, and digital infrastructure can therefore increase orders for its power systems business.

Moving ahead, the company is positive about its opportunities within the AI data center sector. In an earnings call presentation in February 2026, the management said that contributions from data centers accounted for approximately 25% of power generation revenue in Q3 FY26.

There is a strong sense of optimism at the company on the growth potential from this segment.

In the final quarter of 2025, while some industrial segments saw a dip, the power generation segment grew nearly 49%, almost entirely propelled by data center projects and hyperscale inquiries.

AI Data centers require massive, reliable power in a small footprint. Cummins India has stayed ahead by localising high-end technology. The group has 300+ unique data center customers, in 51 countries.

Other than AI data center segments, manufacturing and infra have been doing well for the company.

According to the management, a lot of movement in residential and commercial realty in the last few quarters has led to good momentum and good inquiries.

Cummins India Financial Snapshot

On the financial front, for Q3 FY26, Cummins India posted sales of Rs 30,060 m, remaining steady on a YoY basis. Domestic sales stood at Rs 25,350 m, reflecting a slight dip of 2%, while exports rose by 2% to Rs 4,710 m.

Should You Consider Stocks Catering to the AI Global Boom?

Investors can consider stocks catering to the AI boom in India. However, caution is important.

The opportunity is broader than just "AI software" companies. The bigger and more immediate beneficiaries are often the infrastructure enablers - data centres, optical fibre, power equipment, cooling systems, EPC, and telecom connectivity players.

India's AI and hyperscale data centre capacity is expected to rise sharply over the next 5-7 years as global firms expand local compute infrastructure.

Many AI-theme stocks have already rallied sharply and valuations in some pockets may be ahead of earnings. Not every company mentioning AI will see sustainable profits.

Execution risks, high capex, competition, and dependence on a few large projects remain concerns. The better approach may be focusing on companies with strong balance sheets, existing order books, and clear positioning in the AI infrastructure value chain rather than chasing speculative AI stocks.
