AMD stock rose 4.55% to $233.72 in after-hours trading on November 20, 2025, participating in a broader technology sector rally. The NASDAQ-100 gained 1.70% and major AI-related stocks like NVIDIA surged over 5% following strong earnings reports and AI capability announcements. AMD's momentum is underpinned by its robust Q3 2025 performance, which delivered record revenue of $9.2 billion (up 36% year-over-year) and record profitability, driven by strong demand for EPYC processors and Instinct AI accelerators.[1] The company's strategic partnership with OpenAI to deploy 6 gigawatts of AMD GPUs beginning in H2 2026 continues to support investor confidence in its AI infrastructure positioning.[1]
