South Korean and US Firms Announce 950 Billion Dollars in Five-Year Semiconductor Partnerships at San Francisco AI Summit

BLUFSeoul's near-trillion-dollar commitment hardwires Korean chipmakers into US AI supply chains through 2030, but actual capacity delivery hinges on domestic regulatory timelines that remain untested at this scale.

Presidential policy chief Kim Yong-beom announced during a San Francisco briefing on Saturday that South Korean and global tech firms agreed to pursue $950 billion in combined semiconductor and AI partnerships over five years, following President Lee Jae Myung's summit visit 123. Samsung Electronics signed a $200 billion memorandum of understanding with Broadcom covering advanced memory supply and AI chip foundry cooperation, while SK Group agreed to five-year advance purchase contracts supplying $750 billion in memory chips to Nvidia and other firms 123. The parties also agreed to pursue AI data center projects totaling roughly 5 gigawatts of capacity and about 2 million GPUs, including SK Telecom cooperation with Nvidia and Anthropic and a $10 billion Naver deal with Nvidia and Brookfield 123. Kim said Anthropic CEO Dario Amodei told Lee that Korea could support 2 to 3 gigawatts of AI data center capacity if regulatory approvals move quickly 3.

Analysis
Saturday's announcement converts summit diplomacy into binding commercial terms, locking Samsung and SK Group into US chipmakers' supply chains through advance-purchase contracts rather than spot sales for the rest of the decade. The scale, nearly a trillion dollars, establishes Seoul's three-megaprojects framework as the organizing structure for its AI industrial policy, though four converging but same-day, non-independent accounts limit this to parallel reporting on one coordinated release rather than separately verified reporting threads. Actual data center buildout hinges on how fast domestic regulators clear siting and power approvals, a constraint underscored by Amodei's disclosed estimate that Korea could support 2 to 3 gigawatts of capacity if approvals move quickly. The headline figures may instead largely restate memory contracts and MOUs already in negotiation, repackaged as political messaging timed to Lee's visit rather than newly struck terms.
