Serenity, the stock-picker whose reconstructed views this site tracks, spent Tuesday reinforcing one of his highest-conviction bets: that the memory-chip industry is heading into a multi-year, AI-driven supply crunch rather than the oversupply glut some skeptics still forecast.

His focus was a report, attributed to trade outlet Digitimes citing industry sources, indicating that the largest memory makers have effectively run out of capacity to sell. According to the account he flagged, SK Hynix, Micron and Samsung have already sold through their 2027 capacity for DRAM — the working memory used in PCs and servers — and for HBM, the high-bandwidth memory stacked next to GPUs whose packaging he treats as a key bottleneck in the AI buildout. On the NAND flash side, which stores data, current annual capacity at Samsung, Micron and Sandisk is likewise described as fully booked, with Kioxia and SK Hynix expected to finalize their allocations by August 2026.

The details he highlighted matter to his thesis. He noted that customers are reportedly being granted only 60–70% of the volumes they originally requested, that insiders expect 2027 to mark the most acute point of the shortage, and that while allocation amounts are largely locked, final shipment pricing will be set closer to delivery — a setup that leaves pricing power tilted toward the producers. His pointed takeaway: it is hard to square the "oversupply" narrative some analysts floated for early-to-mid 2027 with makers that are already sold out.

The report speaks directly to his two core memory holdings. Micron, the sole major US-based DRAM and NAND maker, is his largest-conviction name in the theme; he has disclosed a roughly 10% portfolio weight and frames it as a "Made in America" beneficiary insulated from the tariff risk hanging over Korean rivals Samsung and SK Hynix. His underlying model rests on structural AI demand plus repeated price hikes lifting gross margins toward the mid-70s, a level he has said recent results have roughly confirmed, and he expects the stock to re-rate substantially higher over time.

Sandisk, the NAND flash maker spun out of Western Digital, is his template for the same idea on the storage side. He holds it at about 5% of book within a broader memory allocation and treats it as a pricing-power chokepoint over NAND output — partly through its manufacturing tie to Japan's Kioxia. His argument has been that producers are securing multi-year prepayments and pushing NAND prices above analyst estimates, with little supply relief expected before 2028.

Tuesday brought no new trades or position changes — just fresh third-party evidence that Serenity read as validating a call he has held with conviction. For a thesis built on the claim that AI memory demand is effectively permanent while supply stays constrained through the back half of the decade, reports of sold-out 2027 capacity and sub-full customer allocations are exactly the kind of confirmation he has been looking for.
