- AMD was last up 0.4% at $449.59. The stock moved between $431.65 and $451.01 earlier in the session.
- AMD plans to put over $10 billion into Taiwan’s AI supply chain and will scale up output of its next EPYC server chip using TSMC’s 2-nanometer process.
- Amkor said it’s working with AMD on advanced chip packaging in Arizona, a supply-chain step investors are watching.
AMD shares were up late Thursday after the company said it plans to put more than $10 billion into Taiwan’s AI supply chain. Amkor Technology said it’s teaming with AMD on chip packaging in Arizona. The stock rose 0.4% to $449.59, trading between $431.65 and $451.01 during the session.
Wall Street isn’t just focused on who’s making the fastest AI chips now. Investors want to know who can lock down enough manufacturing, packaging and energy-efficient systems to deliver them at scale.
AMD plans to use the Taiwan spending to boost strategic partnerships and ramp up advanced packaging work. Advanced packaging joins multiple chips into one faster and more efficient part. AMD said it will partner with ASE, SPIL, PTI, Sanmina, Wiwynn, Wistron and Inventec as it scales up AI systems.
AMD CEO Lisa Su said customers are “rapidly scaling AI infrastructure” as more of them adopt AI. “As AI adoption accelerates,” she said, the company is working to help customers deploy “next-generation AI systems.” Reuters
AMD said it has started ramping up production of its next-generation EPYC server chip, “Venice,” in Taiwan using Taiwan Semiconductor Manufacturing Co’s 2-nanometer tech. The process should boost speed and cut power use. CPUs, the main processors in servers, are still a big bet for AMD, even as GPUs take the spotlight for AI workloads. GlobeNewswire
Su said customers want platforms that let them go “from innovation to production faster.” TSMC CEO C.C. Wei said AMD is making “strong progress” with the next EPYC chip using the foundry’s 2-nanometer tech. GlobeNewswire
AMD’s Taiwan news links up with its Helios rack-scale platform, which is a whole server rack and not just a single chip. The company said Helios, which uses Venice CPUs and MI450X AI GPUs, is still lined up for deployments starting in the second half of 2026.
Mixed signals for chip stocks. Nvidia, still leading in AI chips, was recently off 1.8%. Intel slipped 0.4%. TSMC’s U.S. shares added 1.4% as chip demand continues to drive more production and packaging to Taiwan and Arizona.
Amkor said Thursday it’s working with AMD to package AMD’s chips. Today’s data-center chips from AMD and Nvidia put multiple chips in one package, and that’s now a bottleneck in production. CEO Kevin Engel told Reuters Amkor is “moving up the value chain.” Reuters
Amkor said it picked up another 67 acres in Arizona next to a 104-acre site pegged for its U.S. advanced packaging and test campus. The company said it expects the expansion to help meet demand from AI, high-performance computing, autos, and communications markets.
AMD ramps up supply-chain efforts after solid Q1 numbers. The chipmaker posted $10.3 billion in revenue, up 38% year over year, with data-center sales at $5.8 billion, a 57% increase, driven by EPYC chips and Instinct GPUs. It guided for about $11.2 billion in Q2 revenue, give or take $300 million.
But after a strong rally, the trade has less margin for error. Analyst targets for AMD are wide, from $200 up to $460, Investing.com said Wednesday, with the market split over how well AMD can convert AI interest into real sales while supply stays tight. The analysis also flagged TSMC’s capacity constraints, Nvidia’s edge in software and systems, and Intel’s gains in server CPUs as ongoing risks.
There’s a clear risk here: if advanced packaging isn’t ready on time, or if customers hold off on large AI projects, or if Nvidia keeps dominating high-end AI budgets, AMD could be waiting longer for its Taiwan plans to feed into earnings. AMD flagged its own set of risks, too. Export controls, tariffs, yields, supply of parts and its dependence on third-party manufacturers could all move results away from its targets.
U.S. stock markets traded as usual Thursday. Both the NYSE and Nasdaq are scheduled to close Monday for Memorial Day, May 25. That means just one more normal session before the holiday break. AMD watchers will probably focus on the supply chain as much as chip prices again.
