July 2 (Reuters) - A ‌consortium including Microsoft ​and ​telecom startup Lightstorm plans to build a new undersea cable linking India with Malaysia and Singapore as technology firms compete ‌to expand AI and cloud infrastructure in India, one of ⁠the world's fastest-growing data markets.

The consortium, whose other members include Tata Communications, Singapore Telecommunications, ‌Singapore's ASEAN Cableship and Japan's ‌NEC Corporation, will construct the I-2SEA cable to support AI, cloud and hyperscale workloads, the companies said on Thursday.

They did not provide additional ​details including the investment size.

The network will span 3,600 km and have landing stations in Machilipatnam in the southern Indian state of ⁠Andhra Pradesh, where Meta and Alphabet have announced data centers.

The cable is expected to be operational ​in the fourth quarter of 2029, Lightstorm Group CEO and Managing Director Amajit Gupta told Reuters in an interview.

The ​I Squared-backed company currently connects 19 AI ‌and cloud zones across India through terrestrial fiber cable networks, with the new network expected to bring this ⁠number up to 29, Gupta said.

India's operational data center capacity could double from the current 1.4 gigawatts by 2027, based on projects under construction, and increase five-fold ⁠by 2030 if planned projects are fast-tracked, Macquarie Equity Research said in a report ​last October.

Undersea cables carry roughly 95% of the world's internet traffic. India currently has 17 active submarine cables with a maximum potential capacity of 960 terabits per ‌second, and at least 10 more have been publicly announced, according to TeleGeography, a telecommunications research firm.

Separately, Lightstorm ‌plans to list in India in mid-2027, Gupta said, without disclosing any other ⁠details. The company was seeking ‌a valuation of up ​to $1.5 billion in March, according to a media report.
