Advanced Micro Devices (AMD) shares climbed 4.9% in midday trading on Friday, reaching $471.48, after CEO Lisa Su said the global central processing unit (CPU) market is facing supply constraints as demand driven by artificial intelligence (AI) outpaces earlier forecasts. The stock touched an intraday high of $481.41 before settling, adding to the chipmaker's momentum as a key player in Wall Street's AI trade.
Speaking in Taipei, Su noted that the overall CPU market has experienced significantly higher demand than anticipated a year ago, describing the market as "tight." She expects supply to increase each quarter this year, with substantially more capacity planned for 2027 and beyond, driven by AI inferencing and agentic AI systems that operate with greater autonomy. The comments come as investors assess whether AI computing demand is broadening or if the trade has become overcrowded.
Massive Investment in Taiwan
AMD announced on Thursday that it will invest over $10 billion across Taiwan's AI ecosystem to expand advanced packaging and manufacturing capacity for next-generation AI infrastructure. Advanced packaging—combining multiple chip components into a single system—has become a bottleneck for high-end AI and data-center processors. The company's Helios rack-scale platform, featuring AMD Instinct MI450X GPUs and 6th Gen EPYC CPUs, remains on track for multi-gigawatt deployments starting in the second half of 2026.
In a significant technological milestone, AMD confirmed that its next-generation EPYC processor, code-named "Venice," has begun production in Taiwan on Taiwan Semiconductor Manufacturing Co.'s (TSMC) advanced 2-nanometer process. AMD stated that Venice is the first high-performance computing product to enter production on TSMC's 2nm technology, with future plans to ramp output at TSMC's Arizona facility.
Competitive Landscape and Supply Chain
AMD is widely viewed as the leading challenger to Nvidia (NVDA) in AI chips, while Intel (INTC) remains a key rival in server CPUs. Nvidia still dominates AI accelerators—chips designed to speed up AI workloads—but AMD positions itself by offering integrated CPU, GPU, and networking solutions for larger data-center systems. Supply dynamics are also shifting, with Amkor Technology (AMKR) announcing on Thursday that it is working with AMD on chip packaging. Amkor CEO Kevin Engel said the partnership moves the company up the value chain, allowing it to extract more value from its services.
Market Context and Risks
Broader market conditions supported AMD's gains, with the Nasdaq Composite rising 0.67% and the Philadelphia semiconductor index up 2.4%, as investors tracked progress in U.S.-Iran talks and moved into technology shares ahead of the Memorial Day weekend. U.S. markets are closed on Monday, May 25. However, risks remain. AMD's first-quarter revenue rose 38% to $10.3 billion, with data-center revenue climbing 57% to $5.8 billion, but the company warned in filings that export rules, tariffs, supply constraints, memory availability, and competition could hurt results. Big packaging and manufacturing investments take years to yield steady supply, and any delay in customer deployments or a cooling in AI spending could quickly dampen sentiment.
Thomas Hayes, chairman at Great Hill Capital, cautioned that investors are assuming a near-term resolution to the Iran conflict, and if that assumption proves wrong, the market could correct sharply. AMD's stock has already priced in significant optimism, making it vulnerable to any negative surprises.
