Samsung union votes to strike, risking Nvidia HBM4 supply disruption

What happened

Samsung Electronics' labor union has voted overwhelmingly to initiate dispute proceedings after wage negotiations broke down, raising the risk of a strike. This directly threatens the supply of HBM4 memory for Nvidia's next-generation AI accelerators. Bullish: A potential production halt at a key HBM supplier creates immediate supply risk and upward price pressure for HBM.
