Micron Slides as a DRAM Price-Fixing Lawsuit Targets the Scarcity Trade

The Lawsuit Puts the Scarcity Trade on Trial

The move that took MU under $1,000 intraday isn't really about the tape — it's about a lawsuit that attacks the story behind the entire run. On June 25, plaintiffs filed a federal antitrust class action accusing Micron, Samsung, and SK Hynix of using their grip on the DRAM market to coordinate capacity cuts in commodity memory like DDR3 and DDR4 — throttling supply under the pretext of shifting wafers to high-bandwidth memory for AI servers, and inflating prices along the way. The complaint, brought by 17 plaintiffs and assigned to Judge Noel Wise, seeks treble damages.

The uncomfortable part for MU longs is that the suit's core allegation *is* the bull thesis. Commodity DRAM prices are up roughly 700% over four years, and that pricing power is exactly what repriced this stock. If the scarcity was manufactured rather than structural, the premium the market paid for it is a lot more fragile. Samsung and SK Hynix have pleaded guilty to DRAM price-fixing before, which is why this filing lands as more than boilerplate litigation.

SK Hynix Opens an Exit Door

The legal cloud arrives at an awkward moment for Micron's status as the default US-listed memory play. SK Hynix plans to begin trading American depositary receipts on Nasdaq around July 10, raising as much as $29 billion in what would be the largest ADR listing on record, surpassing Alibaba's $21.8 billion debut in 2014. For a fund manager building an AI-memory book, that is a direct alternative to MU — and it is the company that leads in HBM. Samsung held about 38% of DRAM revenue in Q1 2026, SK Hynix 29%, and Micron 22%; giving US investors a clean way to own the top names redirects flow that had few places to go but Micron.

Selling the Record Quarter

None of this happened in a vacuum. Micron just posted a record fiscal Q3 — $41.46 billion in revenue against a roughly $35.7 billion estimate — and guided Q4 to about $50 billion, well ahead of consensus. The stock ran to an all-time high near $1,255 on June 25 and is now down about 18% from that peak, a textbook sell-the-news unwind after a move that had MU up about 267% year to date. A new supply agreement with General Motors landed the same week and did nothing to stop the bleed.

For perps traders, the levels are clean. The $1,000 handle is the psychological line the selloff pushed through intraday, and the tape is now trading the gap between a banked record quarter and a forward market where planned Korean capacity expansions have revived talk of an eventual oversupply cycle. The whole memory complex sold off together, which frames this as a repricing of the scarcity premium rather than a Micron-specific stumble.
