AMD Jumps 7% to Lead Three-Session Chip Rally as Intel Price Hike and Huawei Rivalry Reshape the Sector

Advanced Micro Devices led semiconductor stocks higher for a third consecutive session on September 17, 2026, with AMD shares rising 7% to $548.76 in afternoon trading. Broadcom gained 3% and Nvidia edged higher, as investors shrugged off concerns about an AI slowdown and absorbed the Federal Reserve's 25-basis-point rate increase, which lifted its target range to 3.75%-4.00% and signaled at least one more hike ahead from 16 of 18 policymakers.

A key catalyst for AMD's outperformance was Intel's reported move to raise chip prices by roughly 10%, which analysts at Seeking Alpha argued makes AMD the biggest winner of the cycle. As Intel's pricing becomes less competitive, AMD stands to capture additional share in the data center and AI accelerator markets, where the company's Q2 2026 revenue of $11.54 billion grew 50.1% year-over-year and data center revenue more than doubled.

Adding a parallel pricing development, AMD itself has reportedly notified partners of an expected approximately 10% price increase on AI accelerators, consumer GPUs and motherboard chipsets, tied to rising TSMC wafer costs. New pricing policies are planned for Q4, reflecting AMD's heavy reliance on TSMC for advanced-node CPUs and GPUs. TSMC has signaled broad wafer price increases of 5%-10% starting in 2027, making input-cost management a sector-wide concern.

On the competitive front, Huawei launched 11 new AI-related chips at an event in Shanghai, directly targeting Nvidia, Intel and AMD as the Chinese company seeks to fill the void left by US export controls in the Chinese market. Analysts noted that while the announcement highlights a narrowing gap between Chinese and US chip technology, questions remain about whether Huawei can close the performance differential at scale. AMD's expanding data center partnerships and AI-focused product roadmap position it as a key beneficiary if Huawei's challenge pressures Nvidia more than other Western rivals.
