The Apple/CXMT item was already referenced in the earlier coverage as a wildcard. The genuinely new, material developments worth publishing are the Micron-GM Strategic Customer Agreement, the DRAM price-fixing class action escalating, and Qualcomm's HBM-free data center challenge. Writing the brief now.

The memory shortage jumped from the fab floor to the courtroom, as a federal antitrust suit accuses the three companies that control roughly 90% of DRAM of engineering the squeeze that has repriced the entire market.

Seventeen plaintiffs, fourteen individual consumers and three small PC-building and distribution businesses, filed a class action on June 25 in the U.S. District Court for the Northern District of California, accusing Samsung, SK Hynix, and Micron of illegally coordinating to restrict DRAM supply and inflate prices that the complaint says have risen roughly 700% over four years. The case, filed as Garciaguirre v. Samsung Electronics and assigned to Judge Noel Wise, invokes Section 1 of the Sherman Act and targets companies that together hold around 90% of the global DRAM market. The theory is pointed: the suit alleges the makers used the AI-driven HBM shift as a pretext to cut DDR3 and DDR4 output. Micron isn't conceding ground. The company denied the allegations, saying in part that it competes vigorously, fairly and in compliance with all applicable laws wherever it does business, and that it will defend itself against the claims. The bar is high. Proving coordination, as opposed to parallel but independent decisions to chase the most profitable product, is typically the hardest part of such cases. There is precedent worth watching, though: Samsung and SK Hynix have pleaded guilty to criminal DRAM price fixing once before, with the latter paying a $185 million fine in April 2005.

The other side of the shortage story is buyers scrambling to lock supply years out. Micron and General Motors announced a Strategic Customer Agreement on July 1 securing a long-term supply of memory and storage for GM's next-generation vehicle platforms, covering LPDRAM, NOR, and UFS NAND products. The deal is one of 16 Strategic Customer Agreements Micron discussed during its fiscal third-quarter 2026 earnings call. It is backed by Micron's $2 billion investment to modernize its DRAM manufacturing facility in Manassas, Virginia, which began production earlier this year. Notably, the automaker characterized the deal as a precautionary measure aimed at shoring up access to key components, not a reaction to any current supply problems. That an automaker is signing take-or-pay-style contracts on a "just in case" basis is the clearest sign yet that AI's memory pull has cascaded into autos and industrial demand, exactly the durable tailwind that extends this cycle beyond the data center.

Longer term, a challenger to HBM's chokehold is taking shape. Qualcomm debuted a new memory technology it calls HBC, or high-bandwidth compute, designed to compete with high-bandwidth memory and, per the company, deliver a lower total cost of ownership and improved energy efficiency versus HBM. The near-memory design bonds compute with accelerated bandwidth in a 3D-stacked silicon solution, with Qualcomm claiming 6x higher bandwidth per watt than HBM. Commercial sampling of HBC Gen 1 with the AI250 is expected in mid-2027. The threat is real but distant, and the near-term reality still favors HBM incumbents: Qualcomm said it has already inked deals with high-profile customers including Microsoft and Meta, the latter signing a multigeneration agreement to use its Dragonfly C1000 CPU.

Watch whether the antitrust complaint gains a co-plaintiff base of enterprise buyers, which would raise the litigation stakes materially, and whether more OEMs follow GM in pre-committing multi-year memory supply as the shortage grinds on.
