Good morning, it’s Monday, August 3.
Amazon AWS posted its fastest growth since 2021 as the broader company crossed $200 billion in quarterly revenue for the first time, with annual CapEx on track to hit $220 billion on AI infrastructure. On the memory side, CXMT is planning a second Beijing fab while its LPDDR6 hits 12.8 Gbps, and China’s SiCarrier has started mass-producing DUV lithography machines from an unmarked factory. Kioxia also turned heads with an 80% gross margin quarter and an ¥800 billion share buyback.
Let’s get into it. — Austin & Vik

Amazon AWS Posts Fastest Growth in Four Years, Hyperscalers Pile Into AI Hardware
Amazon’s second quarter delivered the company’s first-ever quarterly revenue above $200 billion, with AWS clocking its fastest growth since 2021 and sending shares up roughly 9% after results. The cloud division’s acceleration eased investor anxiety about the spending pace, and Amazon answered by raising its annual CapEx guidance by $20 billion to $220 billion, citing AI memory costs as a primary driver. Amazon’s custom silicon business has reached a $25 billion annualized run rate, a figure that puts its in-house chip operation on a scale few standalone semiconductor companies can match. TD Cowen analyst John Blackledge, appearing on Bloomberg, argued that soaring AWS demand could keep Amazon capacity-constrained through 2027.
Meta added its own weight to the CapEx cycle, lifting its 2026 spending floor by $5 billion and forecasting a total 2026 outlay of $130 to $145 billion. To spread the financing burden, Meta struck joint ventures with BlackRock to fund 1 gigawatt of AI data center capacity, an unusual move for a company that has historically self-funded its infrastructure. Taken together, Bloomberg’s count puts the four largest hyperscalers near $2.4 trillion in committed AI infrastructure spending over coming years.
Behind the demand:
Amazon has deepened its OpenAI partnership via a $50 billion AWS expansion, adding a notable cloud-customer dimension to its own hardware buildout.
The chip rally that followed Amazon and Microsoft earnings extended broadly, with GPU and related semiconductor stocks climbing on the continued CapEx signals.
Across the group, reported cumulative hyperscaler AI spend has crossed $1 trillion, according to TweakTown’s tally of available figures.
Vik: The first signs of revenue from massive AI investments are beginning to show. Really big companies like Microsoft and Amazon and showing huge revenue results. At the current rate, Amazon could reach $1T in annual revenue. The circular financing should resolve eventually? What worries me is the complex financial instruments that are at play.
Austin: Whenever I’m worried about whether this astronomical CapEx, I am reminded that
The huge end customers (OpenAI and Anthropic) are growing faster than ever
Enterprises are increasingly using and benefiting from AI (see Dell earnings, Nvidia’s non-hyperscalers business, and enterprise-centric hardware offerings like AMD MI350P)
And we’re just at the early days of physical AI, which will unlock a huge section of GDP that’s barely touched by AI so far.
CXMT Plans Second Beijing Fab as LPDDR6 Hits 12.8 Gbps
ChangXin Memory Technologies is moving on two fronts at once. Reuters exclusively reported that CXMT is planning a second chip plant in Beijing and is actively in talks on funding for it, a step that would substantially raise China’s domestic DRAM output capacity. The expansion comes as the company is riding momentum from a recent IPO, with Bloomberg noting a $1 trillion target gap that frames how much ground CXMT still needs to cover against the global incumbents. The funding discussions remain ongoing, and no timeline for groundbreaking has been confirmed publicly.
CXMT’s LPDDR6 prototype has cleared R&D verification at 12.8 Gbps, putting it within reach of the speed tier currently occupied by Samsung and SK Hynix’s next-generation mobile DRAM. Digitimes reports the company is closing in on mass production, though full yield validation at volume has not yet been announced. Korea JoongAng Daily describes growing concern inside Korea’s chip industry about exactly this kind of acceleration from Chinese rivals. Lexar has already begun shipping consumer DDR5 modules built on CXMT memory, a sign that the company’s output is finding real commercial channels even before LPDDR6 reaches production.
In related news:
The Korea Herald ties the LPDDR6 progress to the timing of CXMT’s record IPO, framing both as part of a compressed development calendar.
Pandaily puts the mobile DRAM speed at 12,800 Mbps and says research validation is nearing completion, stopping short of a confirmed production date.
Vik: We will continue to track CXMT DRAM progress here because their capacity expansions have implications on the global memory markets. Higher speed DRAM is a checkpoint, which means CXMT can eventually move into the higher performance tiers, but still not HBM.
Austin: “[CXMT] is in financing talks with a tech manufacturing hub backed by the local government…” Textbook game theory goes out the window when one player doesn’t have to make “rational” business decisions, i.e. doesn’t need to hit the same profitability as others due to government support. No idea what the details are here, just reminding myself that “textbook” analysis may not apply here going forward.
China’s Secret DUV Factory and AMEC Push Chip Equipment Self-Sufficiency Toward Reality
SiCarrier, operating out of an unmarked factory in China, has begun mass-producing deep-ultraviolet lithography machines, a development that emerged this week and sent ripples through the equipment supply chain. The facility kept a deliberately low profile, but its existence confirms that China’s domestic lithography effort has crossed from development into production. AMEC, the etching and deposition specialist, has separately announced it will cover more than 100 high-end semiconductor equipment types within five years, targeting 60% coverage of high-end equipment categories by that deadline. AMEC’s ambition runs well beyond its current etch stronghold, stretching into deposition, cleaning, and other process steps where foreign suppliers have held firm.
Together, these moves represent the clearest evidence yet that China’s equipment self-sufficiency drive is turning operational. SiCarrier’s DUV output puts a domestically built alternative on fabs’ procurement lists for mature nodes, compressing the addressable market that ASML and other foreign vendors have relied on inside China. AMEC’s five-year roadmap, reported by both TrendForce and TechNode, extends that pressure across process equipment categories far beyond lithography alone.
In the wider equipment scramble:
Inversion Semiconductor is developing particle-accelerator X-ray lithography as a longer-range challenger to conventional optical approaches, according to Digitimes.
xLight is building a domestic EUV light source and has held discussions about a potential supply arrangement with ASML, Digitimes reports.
Vik: If China manages mature node DUV production, they can meaningfully take over a lot of analog electronics which makes their Robotics stronghold even stronger. It is not always about the AI accelerator business: there is plenty of supply chains that China can dominate with just DUV.
Austin: Interesting. That’s probably the most interesting angle Vik — self-sufficient mature node manufacturing.
Kioxia’s 80% Margin Quarter Raises a Ceiling Question
Kioxia posted an 80% gross margin in Q1 FY26, a figure that makes most semiconductor companies look underdressed, and simultaneously announced a ¥800 billion share buyback alongside a stock split to distribute the windfall. The company also reaffirmed a 50% long-term target for 2028, implicitly conceding that current margins are a temporary high-water mark rather than a new floor. Tech in Asia reports that Kioxia’s own forward guidance signals slower AI-driven NAND growth in coming quarters, an echo of caution that Murata voiced earlier this cycle.
On the product side, Kioxia launched the CM10 SSD series built on PCIe Gen6 and 332-layer BiCS10 NAND, with capacities stretching to 61.44 TB per drive and a clear targeting of AI inference cache workloads. Nikkei Asia places Kioxia inside a broader cohort of memory makers now sitting on roughly $90 billion in combined cash flow from the AI buildout. That cash is real. The growth rate, per Kioxia’s own forecast, is already bending.
Behind the demand:
Kioxia plans to showcase its XL1 CXL-compatible memory expansion module for AI workloads at an upcoming industry event.
FMS 2026 opens with liquid-cooled PCIe 6.0 SSDs and a live debate on AI memory tier architecture among storage vendors.
Vik: If what Murata voiced about the AI buildout slowing down, then NAND forecasts by Kioxia signal similarly. The growth curve will eventually bend down as technology matures, but that has nothing to do with the bubble bursting. We are still only getting started with the era of inference.
