The chief executive of SK hynix this week said that the company's supply of high bandwidth memory (HBM) has been sold out for 2024 and for most of 2025. The claims come on the heels of similar comments made by the CEO of Micron back in March, who said that the company's HBM production had been sold out throughout late 2025. Essentially, this means that demand for HBM exceeds supply.
SK hynix's announcement is more impactful than that of Micron due to the company's larger market presence. Currently holding between 46% to 49% of the HBM market, SK hynix's saturation contrasts starkly with Micron's smaller 4% to 6% market share, based on data from TrendForce. The combined fully booked production capacities of both SK hynix and Micron mean that over half of the industry’s total supply of HBM3 and HBM3E for the upcoming quarters is already sold out. While Samsung (the only remaining HBM producer) yet has to comment about its HBM bookings, it is likely that it faces similar demand and its high-bandwidth memory products are also sold out for quarters to come. That said, it is safe to say that HBM demand can barely meet its supply.
