Samsung Electronics is reportedly set to exclusively supply HBM4 to OpenAI while reallocating over half of its advanced foundry capacity to internal production. This move is driven by surging AI component demand from major customers like Nvidia and AMD. Watch: Potential supply constraints for other foundry customers as capacity shifts internally, but no immediate price or shortage data provided.
