About the company
SK Square is an investment holding company spun off from SK Telecom in 2021, whose primary asset is its approximately 20% stake in SK hynix, plus a portfolio of ICT-related investments. As SK hynix's valuation surged on AI-driven demand in 2025–2026, SK Square's market cap rose sharply, vaulting it to third on the KOSPI. The company also holds stakes in SK Broadband and numerous semiconductor and digital venture funds.
