Three stocks firmly tied to the AI infrastructure buildout, Arm Holdings ARM, Advanced Micro Devices AMD, and CoreWeave CRWV, have all been drawing extra investor attention lately.
Let’s take a closer look at the recent news surrounding each.
Arm Shares Climb 40% in September
Arm Holding shares have surged recently as positivity surrounding agentic AI has fueled optimism for stronger CPU demand. Increasingly capable AI agents could require considerably more CPU-based compute alongside GPUs, and the recent popularity of consumer-facing tools like Meta’s Muse AI agent has only added to the optimism.
In addition, ARM CEO Rene Haas recently expressed increased confidence surrounding the company’s new AGI CPU, indicating that demand remains robust and manufacturing supply is currently the bigger constraint.
Recent results have continued to show strong demand, with ARM generating record revenue of $1.3 billion in its latest release, up 22% YoY, while Data Center royalties more than doubled.

AMD Sees Explosive Data Center Growth
Advanced Micro Devices shares have been similarly red-hot, recently pushing above the $1 trillion market-cap mark for the first time as positivity for AI infrastructure demand continues to grow.
The company has continued to post strong quarterly results, with AMD’s Data Center sales coming in at $6.7 billion in its latest period, reflecting a triple-digit 107% YoY growth rate. AMD expected Data Center sales to accelerate in the back half of 2026, underpinning a favorable growth outlook for both earnings and sales.
Overall sales growth has been stellar across recent periods, regularly showing accelerations.

CoreWeave’s Steep Buildout Costs
CoreWeave similarly remains at the forefront of AI infrastructure names, though shares haven’t seen nearly as much positivity relative to the two mentioned above, up roughly 3% in September.
The company exited Q2 with a massive $104.2 billion revenue backlog, up 246% YoY, with quarterly revenue jumping 112% to roughly $2.6 billion.

While demand is undoubtedly strong, the heavy capital needed to match it has weighed on sentiment, with the company recently announcing plans to raise billions of dollars by selling new stock and debt.
EPS revisions have been on a downward trajectory as a result of the capital-intensive buildout.
