Nvidia's $500B+ Korea AI Infrastructure Deals

The most unusual piece of this package is not the headline number but the plumbing behind the Naver expansion. Nvidia isn't just selling GPUs into Naver's GAK Sejong facility - it's putting $1 billion of its own capital into growing that site from 55 megawatts to 200 megawatts by 2028, with Brookfield layering on up to $9 billion more as the deal's exclusive financing partner ^[1]. That 200-megawatt build-out works out to roughly 100,000 GPUs on the Vera Rubin platform, funded in part by the company that makes the chips ^[2]. That's a structural inversion of the normal chip-industry relationship, where hyperscalers buy compute and vendors just ship silicon. By becoming a co-investor in the data center itself, Nvidia gets a second, deeper lever: it isn't just selling into demand, it's helping construct the demand and then owning a stake in the economics of meeting it. It also functions as a defensive move - keeping a national-champion buyer tightly bound to Nvidia's full stack of chips, DSX architecture, and now capital.

Behind the AI-factory rhetoric is a much narrower and more urgent problem: HBM supply. Nvidia has reserved roughly 70% of its next-generation HBM4 requirement with SK hynix, and each Vera Rubin GPU needs six or more 12-Hi HBM4 stacks at a cost of more than $550 per stack ^[3]. That's happening against a backdrop where AI memory pricing rose 246% in 2025 and HBM3E contract prices are set to climb another roughly 20% for 2026, as the industry's own analysts describe memory as effectively sold out through 2028-2030 ^[4]. Earlier reporting had already flagged SK hynix supplying about two-thirds of Nvidia's HBM4 needs, so this summit's announcement reads as the codification of a dependency that was already forming, not a brand-new one ^[5]. Framed that way, the SK Group partnership's memory piece is less an expansion of ambition than an attempt to buy certainty in the one part of the AI supply chain that is hardest to scale quickly ^[6].

The most politically charged moment of the summit didn't come from Nvidia at all. President Lee Jae-myung, who convened roughly 150 executives around a new 'San Francisco AI Declaration' on US-Korea AI cooperation, used the same stage to raise a pointed question about how gains from deals like this one should be shared ^[8]. His framing - asking directly whether profit margins above 75% should belong solely to the company - signals that Korea's government sees its chip and memory leverage as something that should also buy it a say in how AI-era profits get distributed among firms, workers, investors and the state ^[7]. That tension sits awkwardly next to the celebratory tone of the corporate announcements, and it suggests the $500 billion figure will be read domestically not just as an investment win but as the opening bid in a longer negotiation over taxation and profit-sharing tied to sovereign AI infrastructure ^[9].

Worth scrutinizing is whether a figure like '$500 billion-plus' represents committed capital or a loosely bundled announcement number stitched together from supply agreements, a nonbinding term sheet, and long-run infrastructure targets that may take years to materialize. The nonbinding piece is explicit in the Naver deal itself: Nvidia's $1 billion is subject to customary closing conditions and Brookfield's up to $9 billion sits in a nonbinding term sheet, not a signed check ^[1]. That framing has a real-world market anchor: SK hynix stock jumped sharply in the days around the announcement window ahead of its July 29 earnings, part of a broader chip-stock rebound, even as the company's roughly $856 billion market capitalization already prices in years of anticipated HBM demand ^[10][11]. Layered on top is the separately reported $950 billion of Samsung and SK Hynix chip-supply commitments with US firms through 2030 ^[12][13]- a second enormous headline figure announced in the same window, which makes it harder to tell how much of Korea's 'trillion-dollar AI moment' is durable industrial commitment versus overlapping, mutually reinforcing announcement figures between chipmakers and their biggest customer.
