AMD Stock After Hours Today (Dec. 22, 2025): Alibaba MI308 Order Buzz, China Export Crosswinds, and What to Watch Before Tuesday’s Market Open
AMD shares closed at $214.95, up 0.71% Monday, and traded flat after hours near $215.05. Reports circulated that Alibaba may order 40,000–50,000 of AMD’s MI308 AI accelerators, though neither company confirmed a deal. The stock traded in a wide range amid thin, holiday-shortened volume. U.S. markets close early Wednesday and remain shut Thursday for Christmas.
