Xiaomi's Memory-Chip Pivot: A Homegrown Supply Chain Meets a Brutal Earnings Reality

Xiaomi partners with CXMT for LPDDR6 memory amid 42.6% profit drop, as it raises prices and launches new foldable in a competitive September.

The most consequential decision Xiaomi makes this autumn may have nothing to do with the sleek foldable it unveils in September. Buried beneath the launch fanfare is a supply-chain shift that speaks directly to the company's most painful vulnerability: the soaring cost of memory chips.

ChangXin Memory Technologies (CXMT) has begun mass production of its latest LPDDR6 memory chips, and Xiaomi has signed on as the debut customer. The partnership, confirmed by Xiaomi via its official Weibo channel and reported by Reuters, was reiterated twice in late August — most recently on Monday, when reports pointed to a September launch for the company's upcoming 18 Fold device.

The Cost Squeeze Behind the Strategy

The timing is anything but coincidental. Xiaomi's margins have been under siege from precisely the components CXMT now supplies. In the second quarter of 2026, adjusted net profit tumbled 42.6% to 6.2 billion yuan, while revenue slipped 6.1% to 108.92 billion yuan — a decline the company attributed to elevated memory and component prices.

The scale of that pressure was laid bare by Xiaomi president Lu Weibing, who disclosed that memory costs in Q1 2026 had nearly quadrupled year-over-year, with further price hikes possible. Industry data from TrendForce supports the grim picture: DRAM contract prices are expected to rise 13–18% in Q3 2026, following a quarter in which industry revenue reportedly surged 81%.

The culprit is the AI boom, which is diverting production capacity toward high-bandwidth memory and leaving conventional DRAM and NAND in short supply. For a company that operates on razor-thin mass-market margins, this is a structural problem rather than a temporary blip.

A Domestic Answer to a Global Problem

By positioning itself as CXMT's first customer, Xiaomi is signaling its intent to escape the pricing spiral of global memory makers — at least partially. The logic extends beyond memory: days ago, Xiaomi unveiled a new version of its in-house Xring processor, still manufactured by TSMC but increasingly self-designed.

The message is consistent across both initiatives: reduce dependence on a handful of expensive external suppliers and gain more control over the cost base. Whether CXMT actually delivers cheaper chips than established memory giants remains unproven, but the strategic direction is unmistakable. For investors, this matters beyond the technical details — Xiaomi is positioning itself for a scenario in which trade relations could harden further, with China simultaneously building out its own semiconductor and memory capabilities.

A September Product Onslaught

The company is making this supply-chain pivot in the middle of one of the most aggressive product offensives in its history. Huawei launches its tri-fold Mate XT2 and Pura X View on September 7; Xiaomi counters a day later with the 18 Fold; Apple is expected to unveil a foldable iPhone around September 10, potentially priced near 15,000 yuan. OPPO and another Huawei Mate model follow later in the month.

The 18 Fold itself carries ambitious technology: the self-developed Xring-O3 chip in 3-nanometer fabrication with 24 billion transistors, an AnTuTu score reportedly exceeding five million, and — as the first device to use CXMT's new LPDDR6 memory — bandwidth of 113.8 GB/s, roughly 48% above its predecessor.

Yet the commercial calculus is unforgiving. Reports suggest the Xiaomi 18 will start at 5,499 yuan — a thousand yuan above the previous model. Raising prices in a month when Apple, Huawei, and OPPO are all launching competitive products risks ceding market share. Unconfirmed sales targets of 200,000 to 300,000 units for the 18 Fold suggest cautious expectations.

Xiaomi has also raised prices across several smartphone models in China, alongside Huawei and Honor, with increases ranging from several hundred to over a thousand yuan on devices like the Mi-17 series and Redmi K90. The company has further signaled its operational response through an August management reshuffle and continued portfolio expansion, including the Redmi Note 17 series with a Pro Max variant featuring a 9,210 mAh battery.

What the Market Sees

The stock tells its own story of skepticism. Trading at around 3.02 euros, Xiaomi shares sit 54% below their 52-week high of 6.54 euros, reached last September, and remain 15% under the 200-day moving average. The year-to-date decline stands at 30%, with a 49% drop over twelve months.

The market has clearly priced in the Q2 margin weakness, while the strategic repositioning in chips and memory will only show results over the medium term. The central question for the coming months: can the gradual shift toward domestic suppliers stabilize the cost base before the next memory-chip price cycle tightens further?

Xiaomi finds itself caught between defending margins through necessary price increases and protecting market share in a month of unprecedented competitive pressure. The technological substance — an in-house chip and the latest memory standard — supports long-term competitiveness. But near-term, the combination of cost pressure and product density suggests the stock will remain volatile until the market sees how consumers actually respond to higher prices. The answer will come only with the next quarterly results.
