Sterlite Technologies Surges 500% as AI Boom Drives Optical Fibre Demand

The artificial intelligence revolution is creating unexpected winners in the Indian stock market, with optical fibre manufacturers leading the charge. Sterlite Technologies, a company backed by Vedanta, has emerged as a standout performer, seeing its market capitalization explode from Rs 4,000 crore to approximately Rs 30,000 crore in just six months.

The AI Connectivity Catalyst

The meteoric rise of Sterlite Technologies is fundamentally linked to the global surge in AI adoption. As AI workloads become more compute-intensive, the demand for high-speed connectivity infrastructure has skyrocketed. Optical fibre has become a critical building block for the data centres required to power these complex algorithms.

India is uniquely positioned to benefit from this trend. According to Nomura, India’s data centre IT load has grown from 350 MW in 2019 to nearly 1.5-1.6 GW in 2025, representing a CAGR of 29%—significantly outpacing the global growth rate of 20%. Furthermore, a KPMG report projects that India’s data centre industry revenue could reach $45.69 billion by 2033, driven by rapid cloud adoption and data localisation needs.

Strategic Wins and Global Expansion

A major turning point for the company was securing a massive $1 billion order from a U.S.-based hyperscaler. This win has not only strengthened Sterlite's position in the global AI ecosystem but also provided much better visibility for medium-term growth. Analysts at CLSA have responded optimistically, modelling a 49% EBITDA CAGR between FY26 and FY29.

The company is also leveraging its "Neuralis" portfolio to capture high-end demand. This specialized product line includes ultra-high-density fibre trunks and high-speed interconnect cables capable of supporting up to 6,912 fibres. This vertical integration—moving from manufacturing raw optical fibre to finished connectivity products—makes Sterlite a preferred partner for global hyperscalers looking for single-source suppliers.

Valuation Risks and Market Outlook

Despite the bullish sentiment, seasoned analysts warn that the stock now carries high risks. With recent profitability, the stock has traded at premium multiples, sometimes exceeding 300x TTM P/E, leaving a thin margin of safety for investors.

Market experts suggest that while the structural growth story for the next 3–5 years remains intact, the stock may require a healthy correction before new entries are prudent. Technical analysts note that after hitting a high of Rs 680, the stock has seen a correction, with the Rs 525–530 zone serving as a crucial support level. If the stock maintains this support, the broader bullish trajectory could resume.
