AMD beats revenue, but stock plunges 9%: is AI chip hype cracking?

Core Viewpoint - Advanced Micro Devices (AMD) reported record fourth-quarter revenue of $10.27 billion and exceeded profit expectations, yet the stock fell 9% in premarket trading due to Q1 guidance falling short of Wall Street's high expectations related to AI growth [1] Financial Performance - AMD's Q4 earnings per share were $1.53, beating consensus by $0.21, while revenue of $10.27 billion surpassed estimates by $630 million [1] - Full-year 2025 revenue reached a record $34.6 billion, representing a 34% year-over-year increase, primarily driven by data center demand [1] - The company's non-GAAP gross margin expanded to 57%, aided by a favorable product mix and a $360 million inventory reserve release on MI308 chips [1] Market Reaction - Despite strong fundamentals, the stock selloff indicates a market dynamic where high expectations lead to disappointment even with stellar results [1] - Analysts noted that AMD's unexpected $390 million in shipments to China during Q4 was not factored into street estimates, suggesting the underlying performance was not as robust as headline figures indicated [1] Guidance and Expectations - AMD's Q1 guidance of $9.8 billion (±$300 million) did not meet the aggressive growth expectations set by the market amid AI hype [1] - The market is concerned about AMD's ability to fulfill its significant AI commitments, with major agreements with OpenAI and Oracle that could yield substantial revenue but carry execution and supply-chain risks [1] Competitive Landscape - The selloff reflects concerns about AMD's competitive position against Nvidia, which holds approximately 92% of the AI chip market and recently announced its next-generation Rubin platform [1] - AMD's Q1 guidance still implies a solid 32% year-over-year growth, but the stock's previous rally of over 100% on AI enthusiasm makes the current reality check seem harsh [1]
