SK Group Chairman Chey Tae-won’s fractured wrist has unintentionally become a visual representation of the intricate global AI supply chain.
In a recent Instagram post, Chey shared photos of his wrist cast, worn for approximately eight weeks after a tennis injury. The cast became a unique canvas, adorned with signatures and messages from tech luminaries such as Nvidia CEO Jensen Huang, Meta CEO Mark Zuckerberg, Google CEO Sundar Pichai, and SoftBank Group Chairman Masayoshi Son.
Chey expressed affection for the cast, noting how it became a cherished item as “friends” autographed it during his overseas travels, offering wishes for a speedy recovery. This post marks Chey’s return to social media after an 18-month hiatus.
The photos originated from Chey’s visit to Silicon Valley and Seattle the previous month, where he held meetings with key technology companies despite his injury. These discussions reportedly centered on collaborations in AI semiconductors, with a particular focus on high bandwidth memory (HBM).
HBM has emerged as a crucial component in the AI sector, essential for high-performance AI chips. Demand for HBM has surged alongside the growth of generative AI applications and data center infrastructure. Supply constraints persist, driving leading chip manufacturers to secure their capacity.
SK hynix, the semiconductor arm of SK Group, is a leading global supplier of HBM and a strategic partner to Nvidia, whose GPUs dominate the AI accelerator market. The Korean chipmaker also provides advanced memory products like DDR5 server DRAM to major clients including Google and Meta.
The signatures on Chey’s cast are thus seen as a noteworthy, albeit informal, indication of SK’s position within the AI ecosystem. Industry experts suggest that the presence of these tech leaders’ autographs reflects the ongoing efforts to maintain strong relationships with critical suppliers amid increasing competition for AI infrastructure.
Industry observers also view Chey’s decision to proceed with his US trip while wearing the cast as a demonstration of his commitment to building and maintaining trust with key customers during this period of supply chain challenges.
