Samsung Electronics has announced its biggest-ever share buyback, coming as chip makers reap the rewards of the artificial-intelligence boom. The South Korean company—one of the world's top memory-chip makers—said it will buy back 90 trillion won to 110 trillion won of shares, or about $64.54 billion to $78.88 billion. The move represents the largest repurchase program in the company's history.

The announcement had been widely expected as pressure mounts on Korean chip giants to share the AI windfall with investors. Samsung Electronics' dominance in high-bandwidth memory and advanced packaging has positioned it to benefit significantly from surging demand for AI accelerators and data-center infrastructure.

Samsung Electronics' peer, SK Hynix, unveiled its own program to boost shareholder returns earlier this week, including plans to buy and cancel more than $28 billion of shares. The coordinated actions signal a broader shift in Korean corporate governance toward greater capital returns amid the semiconductor sector's unprecedented profitability.
