Samsung may have just scored a major victory in the HBM race — but now an entirely different problem is threatening to disrupt the momentum. $AMD Here’s what happened: Back on February 12, Samsung announced it had become the first company to begin mass production of HBM4 memory, built using its sixth-generation 1c $DRAM process alongside a 4nm logic base chip. That announcement immediately put pressure on competitors racing for dominance in the AI memory market. By early May, reports confirmed Samsung successfully cleared final HBM4 validation tests with AMD and other partners, and supply preparations were already moving into the next phase by June. Naturally, rivals aren’t ignoring this. If Samsung successfully scales HBM4 shipments during the second half of the year, competing suppliers could see market share slip from above 65% toward the 50–60% range. The pressure is already visible: major hyperscalers like Microsoft, Google, and Amazon are reportedly discussing advance payments to secure future supply capacity elsewhere — a classic sign that large buyers are actively diversifying supplier risk. But despite the technological breakthrough, Samsung now faces a potentially bigger challenge: labor disruption. Wage negotiations involving more than 50,000 workers have reportedly collapsed, and the union announced plans for an 18-day strike beginning May 21.#MarketOverloadWeek #FedMeetsNVIDIAMay20 #Samsung18DayShutdown #CFTCDefendsPredMarkets
