Shares of Micron Technology experienced a 2% decline following reports that Samsung is close to receiving certification from Nvidia for its HBM4 memory chips. Samsung is in the final qualification stage after providing initial samples in September. This move could disrupt the current market dominance of SK Hynix in high-bandwidth memory for AI accelerators.

Samsung's potential entry into the HBM4 market matters because of the growing demand for high-performance memory driven by artificial intelligence applications. Increased competition among memory suppliers like Micron, Samsung, and SK Hynix could impact pricing and market share. Nvidia's Rubin server design is expected to begin shipments around mid-year.

Mizuho analyst Jordan Klein suggests that the qualification progress of Samsung doesn't necessarily mean reduced opportunities for competitors. The demand for HBM4 is expected to exceed the supply. All three memory suppliers are expected to ship HBM4 this year. Investors will be watching the ongoing competition.

As AI continues to evolve, the demand for cutting-edge memory solutions will only grow. This could lead to a very dynamic market. The competition between Samsung, Micron, and SK Hynix will be closely followed. The pricing of HBM4 is expected to be much higher than its predecessor, HBM3e.
