Amkor and NVIDIA expand AI chip packaging partnership with South Korea agreement

Amkor and NVIDIA expand AI chip packaging partnership with South Korea agreement

Money Moves

A $1.3 billion prepayment brings NVIDIA's total commitments to Amkor to $3 billion across Arizona and South Korea.

Today: Amkor and NVIDIA announce $1.3 billion South Korea agreement

Overview

Updated 49 minutes ago

AI chips aren't finished at the foundry. They're mounted with memory onto a base called an interposer and tested in a back-end step — advanced packaging — where demand has outpaced supply, leaving NVIDIA short of finished accelerators.

NVIDIA is prepaying Amkor $1.3 billion to expand packaging capacity in South Korea, the latest in a series of prepayments now totaling $3 billion across Arizona and South Korea. The factories run in 2028. If AI demand holds, NVIDIA buys guaranteed output; if it fades, the money is sunk and Amkor carries the build-out risk.

Why it matters

Amkor's packaging lines are a bottleneck for AI chips — this prepayment decides whether NVIDIA ships next-generation platforms on time.

Scenarios

1

Amkor Hits 300% Interposer Capacity Target by 2028

Likely Resolves by Feb 28, 2029

Discussed by: NVIDIA and Amkor, which announced the 300% target at GTC Berlin

Construction and equipment installation in South Korea stay on schedule, new facilities come online through late 2028, and Amkor reports interposer wafer capacity up more than 300% versus the 2026 baseline. NVIDIA's prepayments convert into contracted output and the partnership expands further.

2

Amkor Delays South Korea or Arizona Expansion

Possible Resolves by Q2 2027

Discussed by: Ainvest analysis, which flagged delivery risk and climbing build costs

Construction, equipment install or qualification slips past announced dates in either country. The Peoria, Arizona campus cost has already climbed from roughly $2 billion in 2023 to about $12 billion by September 2026, pressing near-term earnings through underutilized capacity during the ramp.

NVIDIA Cuts Packaging Commitments as Demand Softens

Uncertain Resolves by End of 2028

Discussed by: Ainvest analysis, noting prepayments are cheap if forecasts hold and sunk if they don't

AI accelerator demand growth slows before the 2028 lines come online. NVIDIA trims or terminates its prepayment commitments, leaving Amkor with funded but underused capacity and heavier debt service on the build-out.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2023–2024

TSMC's CoWoS packaging bottleneck (2023–2024)

AI accelerator demand overwhelmed TSMC's CoWoS advanced packaging lines, which mount chips with high-bandwidth memory onto interposers. NVIDIA and AMD waited months for packaging capacity, and TSMC poured billions into expansion.

Then

TSMC roughly tripled CoWoS capacity by late 2024, and shipping delays eased as AI demand kept climbing.

Now

The episode established advanced packaging as a structural chokepoint in the AI supply chain.

Why this matters now

NVIDIA is now funding Amkor as a second packaging source so it doesn't depend on TSMC's lines alone.

2017–2019

Memory chip boom-and-bust (2017–2019)

Soaring prices for DRAM and NAND memory spurred Samsung, SK Hynix and Micron to build new fabs. Supply caught up with demand in 2019 and prices collapsed, forcing capacity cuts.

Then

Memory makers slashed output and delayed fabs to shore up prices.

Now

The cycle showed how prepaying for capacity years ahead can turn into stranded investment when demand cools.

Why this matters now

NVIDIA's prepayments fund lines that come online in 2028, a horizon long enough for demand to soften.
