Phison's new prepayment policy is a major signal that the power in the memory market has shifted decisively to suppliers.
This isn't happening in a vacuum; it's the result of two powerful forces colliding: disciplined supply and soaring AI-driven demand. This combination has created extreme scarcity, allowing suppliers to dictate terms like pricing and payment conditions.
First, there's the deliberate supply discipline from producers. For months, major NAND manufacturers like Samsung, SK hynix, and Kioxia have been intentionally cutting production. After a period of low prices and financial losses, they decided to tighten the taps to boost profitability. Reports from late 2025 and early 2026 confirm these production cuts, which set the stage for the current shortage. Kioxia, for instance, is reportedly sold out for all of 2026.
Second, there's the AI-driven demand shock. The AI boom has created an insatiable appetite for high-performance storage. Hyperscalers like Google are investing hundreds of billions in data centers, which require massive amounts of enterprise-grade Solid-State Drives (SSDs). This high-margin demand is soaking up available NAND chips, leaving less for consumer products like smartphones and laptops.
Phison's move is a logical, albeit aggressive, response. Caught between scarce supply from NAND makers and huge demand from its own customers, Phison is using prepayment terms to manage risk. This forces its customers—the device makers—to bear the risk of price volatility and ensures that limited inventory goes to those most willing and able to pay. We saw early signs of this when SanDisk tried to secure similar prepaid deals in January and when a top buyer like Apple had to accept significant price hikes from Kioxia.
The "500% spike" mentioned in the initial notice is likely an extreme example from the spot market for specific high-demand parts, but the trend is clear. Contract prices are up significantly, and some enterprise SSDs have seen their street prices triple in under a year. This seller's market is likely to continue through 2026.
- NAND: A type of flash memory used in SSDs, USB drives, and smartphones. It's the standard for high-capacity data storage.
- Phison: A company that designs and sells controllers, the "brain" of an SSD that manages how data is stored and retrieved from the NAND chips.
- Hyperscaler: A massive cloud services provider like Amazon Web Services (AWS), Google Cloud, or Microsoft Azure that operates enormous data centers.
