On August 18, Advanced Micro Devices fell 3.48% in regular trading, trading at $485.31/share, with turnover of $13.64 billion. The decline occurred amid broad semiconductor sector weakness and mixed market reaction to reports of a Google-AMD partnership on next-generation AI chips.

According to a report from semiconductor research firm SemiAnalysis, Google is collaborating with AMD to develop one variant of its tenth-generation TPU, combining Google's TPU architecture with AMD's CPU cores in a co-packaged design optimized for reinforcement learning and agent workloads. While this marks AMD's first foray into custom AI ASIC projects, markets reacted cautiously on short-term execution concerns. Wedbush Securities noted the deal, if confirmed, could reshape the semiconductor industry's competitive landscape.

The broader semiconductor sector was under significant pressure, with Marvell Technology down 6.26%, Intel down 5.19%, Micron Technology down 4.59%, Broadcom down 2.74%, and NVIDIA down 2.06%. In the options market, a $1.14 million far-dated put bet targeting a break below $490 highlighted intensifying bearish sentiment.
