# Nvidia's $3 billion prepayment buys a factory that opens in 2028

> Nvidia is prepaying Amkor $3 billion across Arizona and South Korea for packaging capacity that opens in 2028. Lam Research's cleanroom warning explains why the customer pays two years early, and tonight's earnings show whether the shortage has reached Amkor's order book.

[Nvidia](https://theinference.org/markets/companies/nvidia) is paying [Amkor](https://theinference.org/markets/companies/amkor-technology) $3 billion in advance for packaging capacity that does not exist yet, and [Lam Research](https://theinference.org/markets/companies/lam-research) just told the market why: certified cleanroom space and scarce upstream parts, not demand, are what the AI hardware chain is short of through 2027 [1][2][3]. [The $1.3 billion South Korea agreement announced on October 21](https://www.investing.com/news/company-news/amkor-announces-13-billion-expansion-deal-with-nvidia-in-korea-93CH-4962647), on top of [July's $1.5 billion Arizona prepayment](https://theinference.org/article/nvidia-prepays-1-5-billion-to-skip-the-ai-packaging-queue-america-will-relieve-in-2028), buys Amkor's place in a queue, not chips already rolling [1][2][3].

## Nvidia is prepaying for a cleanroom that opens in 2028

The detail that dates the money: Amkor's $12 billion Peoria, Arizona campus does not open its cleanroom until early 2028 [5]. Nvidia is prepaying two years ahead because that is how long the bottleneck runs. Amkor cannot bridge the wait on its own; fiscal 2025 capex of $900 million against roughly $1.1 billion of annual operating cash leaves about $200 million of free cash flow, so the customer is financing the factory [3].

*Chart: **Amkor's capex has outrun operating cash in three of the last four quarters** Column chart of Amkor's quarterly operating cash flow against capital spending, Q2 2025 to Q2 2026. Capex exceeds operating cash in three of the last four quarters, reaching $435 million against $236 million in Q2 2026.*

*Amkor Technology quarterly figures from its SEC filings, US dollars. Series starts in Q2 2025, after a break in the reported cash-flow series in early 2025. [9]*

The market split over the same fact. Amkor rose 7.1% on the deal, then [fell 10.1% the next session](https://www.theglobeandmail.com/investing/markets/stocks/ENTG-Q/pressreleases/8332483/allegro-microsystems-lattice-semiconductor-amkor-teradyne-and-entegris-shares-plummet-what-you-need-to-know/) after Lam Research said equipment makers cannot meet demand through 2027 because of cleanroom and component shortages [2][4]. Both moves read the same signal: capacity is scarce. The bull case says prepayments prove demand and fund the build; the bear case says the cash lands against 2028 revenue while Amkor, having broken its stock with weak July guidance, still has to execute [3][6].

## One layer down, orders already run at 2.5 times sales

[TTM Technologies](https://theinference.org/markets/companies/ttm-technologies) [reported commercial board orders at 2.5 times sales](https://www.sotkn.com/catalyst/ttm-data-center-boards-115-percent-orders-2-5x-sales/), with laminate and glass lead times of 12 to 24 weeks and rising, and its new lines mostly serve 2028 [8]. Amkor reports fiscal Q3 after the close on October 26, its first print since July, and the closest read on whether packaging shows the same gap [3][6].

*Chart: **Consensus sees Amkor earnings rising 71% in fiscal 2026** Column chart of Amkor normalized EPS: $1.50 in fiscal 2025, consensus $2.57 for fiscal 2026 and $3.30 for fiscal 2028, with estimates dashed.*

*Consensus normalized earnings per share for Amkor Technology, in dollars; fiscal 2026 and 2028 are analyst estimates, shown dashed. [3]*

Shares closed Friday at $39.30, well below their 52-week high, at about 13.9 times forward earnings against a 16.0 five-year average, with [consensus expecting normalized earnings to jump 71% this year](https://www.tikr.com/blog/amkor-rises-4-7-on-new-1-3-billion-nvidia-deal-highlighting-the-critical-role-of-packaging) [3][6][7]. The prepayments turn that build from speculative into customer-funded. What to watch tonight: whether bookings run ahead of shipments. If they do, Nvidia is buying scarce capacity. If not, this is a two-year wait financed by a customer with other packagers.

## Takeaway

Nvidia's $3 billion of prepayments to Amkor shows the AI hardware bottleneck has moved to certified packaging cleanrooms, and Amkor's Q3 report tonight is the first test of whether the order book confirms the shortage.
