Insights

Telecom and infrastructure strategist

SK Telecom signals a major, long-horizon AI data center strategy, but details remain preliminary.

SK Telecom is considering a substantial AI data center buildout of 15GW, starting with 5GW from 2029 and a further 10GW from 2035. This scale suggests an ambition to be a core infrastructure provider for AI workloads, not just a network carrier.

The company is reviewing funding via strategic partners, including global technology and overseas investors, and multiple investment structures. Actual impact will depend on final investment amounts, partner mix, and timing, none of which are fixed yet.

Execution will be sensitive to changes in market demand, power supply, land acquisition, regulatory permits, approvals, and financing. Subsequent disclosures, once specific projects and capital commitments are defined, will better indicate the financial burden and potential returns of this long-term AI infrastructure strategy.
