NVIDIA and Amkor Technology have entered a multi-year, $1.5 billion agreement to expand advanced semiconductor packaging and testing capacity in the United States. The AI chip race is no longer only about designing faster GPUs; it is also about getting those chips assembled, packaged, and tested fast enough to meet demand. As Nvidia and Amkor announced the deal, shares rose about 17% in after-hours trading.
Amkor is one of the major names in advanced packaging, the stage where chips are assembled into the form used in real systems. In AI hardware, that step has become a constraint because modern accelerators depend on complex packages that combine multiple chip components, memory, and interconnects. Amkor is expanding its Arizona footprint and has been working with other major chip companies on advanced packaging, which underlines how strategically important this layer of the supply chain has become.

The company has been riding strong demand for AI infrastructure, and the packaging stage is one of the places where output can get stuck even when chip design demand is strong. By locking in more packaging and testing capacity in the U.S., NVIDIA is strengthening the part of the supply chain that sits between chip fabrication and final delivery.
Here, Amkor is an outsourced semiconductor assembly and test company, which means it specializes in the post-fabrication work that makes chips usable in finished systems. Amkor’s role is important as AI processors grow more complex and packaging becomes harder to scale.
Packaging is becoming a key layer within semiconductor manufacturing, much like foundries did in earlier phases of the chip boom. Other chip firms, including AMD and Apple-linked supply chains, are also leaning on Amkor and similar partners as they expand U.S. capacity. The NVIDIA-Amkor deal looks more like part of a wider reordering of the AI hardware supply chain.

Amkor shares jumped about 17% in after-hours trade after the agreement was announced. That reaction suggests investors see advanced packaging as a direct beneficiary of the AI buildout, not a back-end service business with limited upside.
NVIDIA’s $1.5 billion deal with Amkor is a supply-chain move. It shows how AI demand is changing semiconductor manufacturing from the inside out.
