Nvidia-SK Hynix & Samsung-Broadcom Lock In $950B HBM Supply Agreements

Nvidia and SK Group have announced a $500 billion-plus strategic initiative anchored by a long-term HBM supply partnership between Nvidia and SK Hynix covering HBM4 memory for Vera Rubin-generation AI accelerators, with first deployment targeted for 2027. Samsung Electronics has separately signed a $200 billion collaboration with Broadcom spanning memory, foundry, and advanced packaging services through 2030. South Korea's presidential adviser confirmed that the country's two memory giants have committed to $950 billion in supply partnerships with U.S. technology companies—$750 billion from SK Hynix and $200 billion from Samsung—representing the most significant multi-year HBM supply lock-in disclosed publicly to date.

SK Telecom is constructing a 2-gigawatt AI data center powered by HBM4 technology, targeting an online launch in 2027. Meanwhile, TSMC's CoWoS and advanced packaging capacity is described as largely booked through 2027, leaving limited availability for uncontracted orders.

The scale and exclusivity of these bilateral agreements effectively tighten available HBM spot and contract market capacity for buyers outside these partnerships, raising procurement risk and likely establishing a floor price for uncontracted HBM3e and HBM4 memory through at least 2027. Samsung's $200 billion pact with Broadcom signals an emerging credible second source for foundry and advanced packaging alongside TSMC, which could modestly relieve concentration risk in packaging over a two- to three-year horizon, though it offers limited relief for near-term supply constraints.
