Samsung may have just made the HBM race interesting again, but the timing couldn’t be more risky. After months of pressure, Samsung finally seems to be gaining momentum in HBM4. Reports say it moved ahead with advanced mass production using its latest DRAM process and a 4nm logic base die, with $AMD and other partners already testing the supply pipeline. That matters for $AMD because HBM supply is one of the biggest bottlenecks in the AI hardware cycle. If Samsung can scale properly, it could reduce dependence on one dominant supplier and give major buyers more negotiating power. But here’s the problem: Samsung’s technical win is now colliding with a labor risk. More than 50,000 workers are reportedly preparing for an 18-day strike after wage talks broke down. And this is happening right when HBM4 supply is supposed to ramp. So the real question isn’t just whether Samsung can build HBM4. It’s whether Samsung can deliver it at scale without disruption. For AMD and the broader AI chip supply chain, this could become a key story to watch heading into the second half of the year. Tech race won? Maybe. Supply race? Still wide open. $AMD #SamsungStrikeCrisis #OpenAIvsAnthropic #TrumpPressuresIran
