TrendForce Puts 2025 DRAM Module Revenue at $21.2 Billion, Up 59% as Inventory Determined Who Could Serve Tight Supply

Tightness in the DRAM module market is moving value beyond wafer makers and toward distributors and module houses that already hold chips. TrendForce estimated on September 22 that global DRAM module revenue reached $21.2 billion in 2025, up 59% year on year after 7% growth in 2024 [1]. That is a market-research estimate, not a simple sum of audited results from every module supplier. It nevertheless shows that the previous price upswing did not accrue only to the upstream makers.

TrendForce places the inflection in the second half of 2025. North American and Chinese cloud providers increased server-DRAM orders, the firm said, while supplier allocations for PCs and consumer devices tightened; module prices and shipments then rose together [1]. Its report puts the top five module makers at 77% of 2025 revenue, with Kingston at 62%. The point is not that every channel supplier benefited equally. Procurement scale, inventory cost and customer mix determined who could turn scarce chips into revenue.

ADATA offers a limited, checkable company-level view. It reported NT$5.81 billion in consolidated December 2025 sales, up 101.21% year on year, and NT$53.04 billion for the full year, up 32.48%; DRAM represented 69.0% of December product sales [2]. That does not independently validate the 59% global estimate: ADATA's figures also include SSDs and other products, and its 2025 numbers were unaudited at the time. It only establishes that a DRAM-heavy supplier was exposed to the same price-and-inventory cycle.

John Wood's analysis is that this retrospective makes the shortage more specific: it was also a test of inventory management at the module layer, not proof that demand will keep rising at the same rate. More expensive chips lift reported revenue, but they also consume working capital. Suppliers with too little stock can miss orders; those with too much stock face markdown risk if prices reverse. Watch 2026 inventory days, procurement financing and actual RDIMM shipments, as well as whether server demand can still offset price elasticity in PCs and consumer devices. Until then, 59% is evidence of a completed annual revenue change, not a forecast for the next year.
