Storage stocks are broadly lower in premarket trading, with SK Hynix down more than 4%. SanDisk, Micron, Western Digital, and Seagate are all sliding in sympathy. The news came from Nikkei: Terafab, the project Musk is building with Tesla and SpaceX, aims to ramp up to 1 million wafers a month by 2032, with 70% dedicated to memory—enough to rival Samsung’s current DRAM capacity.

A procurement team reportedly flew to Japan in early November to discuss equipment, and one supplier was asked to deliver within a few months. That doesn’t sound like idle talk. Micron was up 5% last Friday, and sentiment flipped in a day. Everyone’s eager to get in on this red-hot memory rally, but who knows whether prices will hold up if that much new supply actually comes online six years from now.
