Nvidia is bankrolling AI accelerator supply chain buildout to reserve production capacity
On October 21, during GTC Berlin, Nvidia announced several multi-billion-dollar deals with six major supply chain partners — Ibiden, Unimicron, Samsung Electro-Mechanics, SPIL, Amkor and KYEC — across substrates, advanced packaging, semiconductor testing and optical engines, to expand production capacity and reserve capacity for its AI accelerators; expanded supply is to be available from 2027 through 2028, with commitments and production roadmaps stretching through 2028. For substrates, Nvidia plans to secure 2.5x dedicated substrate capacity over the next three years: it earlier signed a deal to provide a multibillion-dollar capacity reservation advance to support Ibiden's Ono Plant in Japan (targeting 3x the plant's current capacity); the Samsung Electro-Mechanics deal will support facility upgrades and new plants in Busan and Sejong, with Nvidia projected to account for a significant portion of its output by 2028; a capacity reservation agreement with Unimicron supports its substrate expansion in Taiwan, expected to start providing capacity by Q2 2027 and reach full capacity by mid-2028. For co-packaged optics, Nvidia signed with SPIL to expand optical engine production capacity 15x (1,400%) by mid-2027, with plans to double again by the end of 2028. With Amkor, Nvidia targets a more-than-300% increase in interposer wafer capacity by the end of 2028 through advanced packaging expansion in South Korea; Amkor confirmed the deal is worth $1.3 billion, bringing Nvidia's total investment across Amkor's Arizona and South Korea facilities to $3 billion. For testing, on October 13 Nvidia signed a deal to pay KYEC $1.1 billion to reserve testing capacity at KYEC's new $1.4 billion U.S. facility (high-volume production slated to begin in April 2027; Singapore high-volume production expected to begin February 2027), with testing capacity expected to double from calendar 2026 to 2027; KYEC currently handles nearly all of Nvidia's chip testing. Per its August 2026 disclosures, Nvidia had accumulated $279 billion in outstanding supply and manufacturing-capacity commitments by July 2026. All expansion figures are announced plans and targets, not yet realized.
