AMD Outlook Drives AI-Fueled Surge in US Chip Stocks

Rise in Semiconductor Stocks

U.S. semiconductor stocks experienced a significant increase on Wednesday, driven by a strong outlook from Advanced Micro Devices (AMD). This optimism has bolstered investor confidence regarding sustained demand for AI infrastructure and the potential for increased spending as there is a shift towards central processing units (CPUs).

AMD's stock surged nearly 18% in premarket trading, setting it on a path to potentially reach a record high if these gains continue during market hours. Intel's shares also rose by 6%, while Arm Holdings saw an impressive 11% increase. Qualcomm added about 4% to its value, and Marvell Technology gained 1.7%. Micron Technology experienced a notable surge of 6.4%.

Shift to CPUs and AI Infrastructure

Central processing units have become increasingly important as companies and businesses move towards agentic AI systems that can perform autonomous functions. This shift has broadened the demand beyond graphics processing units (GPUs), which are traditionally used for training large models.

Like its competitors Nvidia and Intel, AMD recently stated that a focus on "inference" — where AI models are deployed in real-world applications — is opening up new opportunities for its server CPUs. The company now expects the server CPU addressable market to grow by more than 35% annually through 2030, up from a previous forecast of 18%.

Broader Compute Opportunities

According to Matt Britzman, senior equity analyst at Hargreaves Lansdown, the AMD story is no longer just about having a GPU pipeline to challenge Nvidia. Instead, it's increasingly about broader compute opportunities, with both CPUs and GPUs playing roles as AI workloads become more demanding.

AMD's shares have had their best month in April since the dotcom era, climbing about 66% for the year, outpacing Nvidia's gain of 5%. Despite this, AMD trades at about 39.66 times forward earnings, significantly higher than its five-year average and nearly double Nvidia's roughly 21-times multiple, even though Nvidia holds a much larger share of the AI market.

Samsung's Market Value Milestone

Earlier in the day, Samsung Electronics became only the second Asian company to reach a $1 trillion market value, fueled by an AI-powered rally.

Super Micro's Surge Amid Legal Challenges

Super Micro also saw a significant rise of nearly 19% after forecasting fourth-quarter revenue and profit above expectations. This reassured investors who were concerned about a recent U.S. Justice Department case involving illegal chip shipments to China.

The company's outlook highlights strong demand for its customizable, high-performance AI servers from data-center operators and startups. CEO Charles Liang noted that demand was also robust for its broader data-center and cloud software offerings, with production sites in Taiwan, Malaysia, and the Netherlands ramping up aggressively.

J.P. Morgan analysts attributed the better-than-expected outlook to margin recovery and customer diversification but pointed out corporate governance issues as a lingering concern.
