On October 21, 2025, AMD stock closed at $237.21 (-1.39%) in after-hours trading. The decline followed leaks about upcoming Ryzen 7 and Ryzen 9 CPUs, which revealed that the new Ryzen 9 9950X3D2 may have a lower maximum clock speed than its predecessor, raising concerns among investors[2]. Despite the slip, AMD remains a focal point for Wall Street due to its recent partnership with OpenAI and strong positioning in the AI chip market, which have driven a 43% rally since the announcement earlier this month[1][3]. Analysts remain optimistic ahead of AMD’s Q3 earnings in early November, citing robust demand for AI infrastructure and improved PC/server chip outlooks[1][3].
