- AMD shares were recently up 0.4% at $449.59 after swinging between $431.65 and $451.01 during the session.
- AMD said it would invest more than $10 billion across Taiwan’s AI supply chain and ramp production of its next EPYC server chip on TSMC’s 2-nanometer process.
- Amkor said it is working with AMD on advanced chip packaging in Arizona, a supply-chain step investors are watching closely.
Advanced Micro Devices shares edged higher late Thursday after the chipmaker said it would invest more than $10 billion across Taiwan’s artificial-intelligence supply chain, while Amkor Technology said it is working with AMD on chip packaging in Arizona. AMD was recently up 0.4% at $449.59, after touching a session low of $431.65 and high of $451.01.
The move matters because Wall Street is no longer watching only who designs the fastest AI chips. Investors are also asking who can secure enough manufacturing, packaging and power-efficient systems to ship them at scale.
AMD said the Taiwan spending would expand strategic partnerships and scale advanced packaging, the process of joining several chips into one faster, more power-efficient module. The company said it will work with ASE, SPIL, PTI, Sanmina, Wiwynn, Wistron and Inventec as it builds out AI systems.
“As AI adoption accelerates,” AMD CEO Lisa Su said, customers are “rapidly scaling AI infrastructure.” She said the company is trying to help them deploy “next-generation AI systems.” Reuters
AMD also said its next-generation EPYC server processor, code-named “Venice,” has started ramping production in Taiwan on Taiwan Semiconductor Manufacturing Co’s 2-nanometer process, an advanced chip-making technology meant to improve speed and power use. A CPU, or central processing unit, is the main computing engine in a server; AMD is betting CPUs will stay important even as GPUs, or graphics processors used to accelerate AI calculations, get most of the attention.

Su said customers need platforms that can move “from innovation to production faster.” TSMC CEO C.C. Wei said AMD was making “strong progress” with the next EPYC chip on the foundry’s 2-nanometer technology. GlobeNewswire
The Taiwan announcement also ties into AMD’s Helios rack-scale platform, a full server-rack system rather than a standalone chip. AMD said Helios, built around Venice CPUs and MI450X AI GPUs, remains on track for deployments starting in the second half of 2026.
The competitive read-through was mixed. Nvidia, still the dominant AI chip supplier, was recently down 1.8%, while Intel slipped 0.4%. TSMC’s U.S.-listed shares rose 1.4%, helped by the same demand story that is pulling more chip production and packaging work into Taiwan and Arizona.
Amkor said Thursday it is working with AMD on packaging AMD’s chips. Modern data-center processors from AMD and Nvidia often combine several chips in one package, and that step has become a production bottleneck. Amkor CEO Kevin Engel told Reuters the company is “moving up the value chain.” Reuters
Amkor earlier said it had secured another 67 acres in Arizona next to a 104-acre site where it plans a U.S. advanced packaging and test campus. The company said the site is meant to support demand from AI, high-performance computing, autos and communications markets.
AMD’s latest supply-chain push follows a strong first quarter. The company reported revenue of $10.3 billion, up 38% from a year earlier, and data-center revenue of $5.8 billion, up 57%, helped by EPYC processors and AMD Instinct GPU shipments. It forecast second-quarter revenue of about $11.2 billion, plus or minus $300 million.
But the trade has less room for error after a sharp run. Investing.com said Wednesday that analyst price targets on AMD ranged from $200 to $460, reflecting a split over whether the company can turn AI demand into supply-constrained revenue. The same analysis pointed to TSMC capacity limits, Nvidia’s software and system advantage, and Intel’s improving server CPU position as risks.
The downside case is plain enough: if advanced packaging capacity arrives late, if customers delay rack-scale AI deployments, or if Nvidia keeps most high-end AI spending locked into its platform, AMD’s Taiwan investment may take longer to show up in earnings. AMD itself warned that export rules, tariffs, manufacturing yields, component supply and reliance on third-party manufacturers could cause results to differ from its plans.
U.S. equity markets were open Thursday; the next listed full closure for both NYSE and Nasdaq is Memorial Day on Monday, May 25. That leaves one regular U.S. trading session before the long weekend, with AMD investors likely to keep watching supply-chain headlines as closely as chip benchmarks.
