Meta's announcement of a cloud business to sell excess AI computing capacity caused its stock to rise over 10% while South Korean chipmakers and specialized cloud providers saw declines. South Korea's Kospi index plunged 8-10%, driven by selloffs in SK Hynix and Samsung Electronics, both critical suppliers of high-bandwidth memory for AI workloads. Korean chipmakers have committed roughly $518 billion to new AI-focused factories. Meta's projected AI infrastructure spending for 2026 is up to $145 billion, with the industry-wide total expected to exceed $700 billion for the year. CoreWeave shares dropped 13%, and Nebius Group fell 15%. The article notes that if oversupply fears prove justified, excess capacity in AI compute could benefit decentralized computing networks like Render and Akash.
