On June 25, 2026, Apple raised prices on the Mac and iPad, citing AI-driven memory shortages, and its stock fell 6.15% that same day. What's less widely known is that the workaround Apple had been pursuing behind the price hikes has ignited a new political controversy. On July 29, 2026, six bipartisan U.S. senators sent a letter pushing back against Apple's move to adopt China-made memory chips from CXMT and YMTC, demanding written confirmation by August 21 that Apple would not use them. This standoff is almost a replay of a plan Apple was forced to abandon once before, in 2022—and a new economic pressure, AI-driven memory shortages, is bringing back embers that once seemed extinguished, in a different form.
The Letter's August 21 Deadline and Demand for Technical Disclosure
On July 29, 2026, a bipartisan group of six senators—led by Republican Senator Jim Banks (Indiana) and Democratic Senate Majority Leader Chuck Schumer (New York), joined by Senators Kim, Shaheen, Crapo, and Ricketts—sent a letter addressed to CEO Tim Cook. Their demand was clear: written confirmation by August 21 that Apple would not procure any memory chips from CXMT or YMTC. According to multiple independent U.S. outlets, including 9to5mac, the letter's content, the signatories, and the deadline are consistent across reports, lending high credibility to the facts.
The letter jointly characterized the plan as "shortsighted," warning that it would make "the world's most valuable consumer electronics company" dependent on critical component supplies from companies the U.S. government has formally designated as Chinese military enterprises. This phrase—"formally designated"—has a concrete basis. CXMT and YMTC remain listed on the U.S. Department of Defense's "1260H List" (a designation system for Chinese companies supporting the People's Liberation Army), which was updated on June 8, 2026, giving them legal standing as military-linked entities as well.
The senators further demanded disclosure of the technical information Apple shared with CXMT during qualification reviews, noting that technology transfers to advanced Chinese manufacturing facilities may require export licenses from the Department of Commerce. They also warned that even if procurement is initially limited to products sold within China, a single sourcing decision could extend it worldwide, and expressed concern in the letter that domestic memory-related investments in states such as Indiana, Idaho, New York, and Virginia could be undermined. What the letter demands is a simple binary choice—written commitment to forgo CXMT and YMTC, or not—leaving Apple little room to negotiate.
The letter itself does not specify concrete sanctions or legal enforcement mechanisms should Apple fail to make the commitment by the deadline. The August 21 date should be understood less as a legally binding deadline and more as a political pressure line meant to force Apple to state its position. Still, there is precedent: in 2022, following remarks from Senator Rubio and tightened export controls on China that October, Apple withdrew its plan to adopt YMTC components—so the written pressure from these six bipartisan senators carries real political weight.
How AI Is Swallowing Memory Supply—and Why Apple Reached for Chinese DRAM
Demand for HBM (High Bandwidth Memory) used in AI accelerators like NVIDIA's has surged since the start of 2026, prompting Samsung, SK hynix, and Micron to redirect much of their production capacity toward HBM. Because these three companies together account for roughly 90% of global DRAM revenue (Samsung 38%, SK hynix 29%, and Micron 22% in Q1 2026), the structure means that any shift toward HBM directly squeezes the supply of general-purpose DRAM. This is precisely why Apple, despite the political risk, reached for Chinese-made memory.
Prices for general-purpose DRAM, its supply constrained, are reported to have jumped several-fold over the past year. Mass-market products like the Mac, iPad, and iPhone depend on general-purpose DRAM and NAND, and unable to fully absorb the rising costs, Apple raised prices on the Mac and iPad on June 25, 2026. Apple's stock fell 6.15% the same day the price hikes were announced—suggesting the market was less concerned about the cost increase itself than about the uncertainty of how long the shortage would persist. AI-related demand is expected to keep growing for the foreseeable future, and there is little reason to expect the general-purpose DRAM shortage to resolve quickly.
This is the context in which CXMT enters the picture. According to analyst assessments, CXMT—the world's fourth-largest DRAM maker—derives over 98% of its DRAM revenue from general-purpose products and has barely entered the HBM business. It is one of the few suppliers with production capacity that doesn't compete with AI-driven demand, making it a practical option for Apple to keep costs down. As of July 8, 2026, Apple had already begun testing CXMT-made DRAM, and reportedly is seeking approval from senior administration officials, including Treasury Secretary Bessent, to expand what was initially a China-only-market plan to include products sold outside China as well.
The same analyst also notes that CXMT's manufacturing technology lags two to three generations behind Samsung, SK hynix, and Micron. Low price and technical capability are separate matters, and the prevailing view is that Chinese memory will, for now, serve mainly to ease cost pressures in mainstream-priced products—falling short of a substitute for cutting-edge memory.
An Echo of 2022: Rubio's Warning and the "Playing with Fire" Remark
In 2022, Apple was considering adopting YMTC-made NAND for iPhones sold in China. At the time, Senator Marco Rubio, then vice chairman of the Senate Intelligence Committee, said Apple was "playing with fire," warning that moving forward with the plan would subject the company to unprecedented federal scrutiny. That same year, Senators Warner and Rubio asked the Director of National Intelligence (DNI) to review the risks posed by YMTC, pointing out that 24,000 jobs in the U.S. memory industry were at stake. Apple ultimately withdrew the plan.
In 2022, Apple faced no clear cost-driven urgency to use YMTC components; in 2026, by contrast, Apple has actually been forced into price hikes and a stock decline by AI-driven memory cost spikes. And whereas YMTC in 2022 was a privately held company, CXMT went public on Shanghai's STAR Market on July 27, 2026, reaching a market capitalization of roughly $489 billion (based on closing price, up roughly 466% from its offering price)—making it China's largest IPO since 2010. The logic of congressional pressure grounded in national security and threats to domestic employment hasn't changed since four years ago, but the strength of the economic necessity driving Apple, and the capital-market presence of the company now under criticism, are clearly different.
In 2022, Apple was forced to withdraw the plan about a month after it surfaced in reporting; by 2026, Apple has already moved into trial procurement and is even seeking Treasury Secretary approval. This gap shows that Chinese-made memory has shifted, within Apple, from a mere option under consideration to an established course of action already being implemented. Rather than a rerun of the same script, this looks more like a scene in which the side that lost once before is trying again with an economic tailwind at its back.
In 2022, Senators Warner and Rubio only went so far as requesting a DNI risk review of YMTC; no formal government designation accompanied it yet. The 1260H List of 2026, by contrast, is a document in which the Department of Defense itself has formally designated CXMT and YMTC as military-linked enterprises—meaning the senators' argument now rests on a more official foundation than it did in 2022. What has changed is the weight of the evidentiary basis, and the stage of the standoff itself differs from four years ago as well: whether Apple retreats while still at the consideration stage, or gets cornered after having already advanced to trial procurement.
The very fact that this tug-of-war is repeating itself four years later reflects a fragility in U.S. semiconductor security policy. The logic of national security is supposed to remain consistent regardless of who is in charge or which administration holds power, but the logic of cost rationality swings widely with market conditions. In 2022, the latter was held in check; in 2026, the economic pressure of shortage is strengthening the latter's force.
Apple, Micron, and CXMT: A Three-Way Tug-of-War—Who Wins, Who Loses
Apple itself stands to lower its procurement costs. CXMT and YMTC, meanwhile, gain something invaluable to investors: a track record of doing business with one of the world's biggest brands. The stock's sharp rally right after listing is a direct reflection of just how high that expectation runs. The mere fact that a top-tier global brand considered them can shift market confidence in CXMT's products.
Micron, even as it lobbied the White House to oppose the plan, had just raised its planned U.S. investment from $200 billion to $250 billion through 2035. On July 27, 2026, the day CXMT's listing became known, Micron shares fell 5%, SanDisk fell 12%, Western Digital fell 7%, and SK hynix's U.S. depositary receipts (ADRs) fell 6% as well. Samsung and SK hynix, too, stand to lose pricing power if Apple—a major DRAM customer—shifts business toward Chinese suppliers. The stock declines that day show that the market read CXMT's rapid rise as a warning sign for established memory majors as a whole.
Samsung, SK hynix, and Micron were hit with a class-action lawsuit in the United States on June 25, 2026, over alleged coordinated production cuts to inflate DRAM prices (Apple is not named as a defendant). With the three companies that control roughly 90% of global DRAM revenue under suspicion of price manipulation, Apple has little economic reason to keep relying on them. BoiseDev, citing information originating from the WSJ, reported that Apple has pointed to Micron's gross margin exceeding 80% and pushed back, characterizing it as price gouging amid the supply shortage. Though not named as a plaintiff in the class action, Apple is effectively applying indirect pressure on the pricing of the incumbent three companies through its own procurement decisions.
The decline in shares of NAND majors SanDisk and Western Digital was steeper than that of DRAM major Micron. CXMT's surge was a DRAM-market event, but investors may have sold NAND-related stocks even more aggressively, anticipating that YMTC—another leading Chinese memory maker—would similarly strengthen its position in the NAND market.
Indiana, Idaho, and New York: The Local Interests Behind the Letter's Signatories
Senator Banks's home state of Indiana has an agreement under which SK hynix will invest $3.87 billion in an advanced chip packaging business. Senator Crapo's home state of Idaho is literally home to Micron's headquarters. Senator Schumer's home state of New York is also one of Micron's largest U.S. investment destinations. The districts of the three senators who led the letter all directly overlap with major memory manufacturers' investments.
This is not to say the letter's argument is unwarranted. But the very overlap of these names illustrates the dual structure of this issue: expanded procurement of Chinese-made memory is simultaneously a "national security threat" and an "economic issue tied to protecting local jobs and investment." A standoff often framed purely in security terms is, in practice, built on the substructure of each state defending its own semiconductor industry.
Senator Schumer holds the leadership position of Senate Majority Leader, and his signature adds to the weight of bipartisan pressure. The very fact that Republican Senator Banks and the top Democrat in the Senate appear on the same letter underscores that this issue is one where partisan lines converge easily around regional industrial defense rather than partisan conflict. The breadth of the six signatories—including Senators Kim, Shaheen, and Ricketts—also indicates that this concern is not confined to any single state or party.
Ripple Effects on KIOXIA, and the Fork in the Road Expected After August 21
In the NAND flash memory space, Japan's KIOXIA, backed by Toshiba, directly competes with YMTC. If Apple expands its business with CXMT or YMTC, it will change the very strength of the competitor KIOXIA faces on price. Micron's increased U.S. investment of $250 billion, converted at the July 25, 2026 exchange rate (1 dollar = 163.5 yen), comes to roughly ¥40.9 trillion—a figure that conveys the scale of this standoff in yen terms as well.
On July 16, 2026, House Select Committee on the CCP Chairman John Moolenaar and others sent a letter to the Secretary of Commerce stating that "each of China's major memory semiconductor manufacturers is closely tied to the Chinese military," and calling for the export ban to be maintained. The Senate letter is in step with this House action, with lawmakers from both chambers pressuring Apple and the administration alike through separate letters.
The 1260H List, overseen by the Department of Defense, is the document that has designated CXMT and YMTC as military-linked enterprises. Should the Treasury Secretary approve procurement in contradiction of this designation, it would also expose a rift in coordination between the Department of Defense and the Treasury Department. By the August 21 deadline, the paths available to Apple narrow down to two: withdraw the procurement plan under congressional pressure, as it did in 2022, or push through congressional opposition with Secretary Bessent's approval. The fact that Apple has already advanced to trial procurement shows it is now at a point further along—and harder to walk back from—than it was four years ago.
For semiconductor security policy to regain consistency here, the administration and Congress need to establish a shared standard for how general-purpose memory should be treated, ahead of procurement decisions by private companies like Apple. Until that happens, standoffs of this kind are likely to keep recurring.
