Nvidia is letting rival AI accelerators into its racks, as Reuters reported September 10 that inference-chip startup d-Matrix will use Nvidia's NVLink Fusion technology to connect its next-generation Raptor processors directly into Nvidia data-center racks, with the systems expected to become available in 2027. Astera Labs is working with d-Matrix on custom connectivity solutions to move data rapidly across the system, creating a three-layer architecture in which d-Matrix supplies the accelerator, Nvidia supplies the rack-scale interconnect technology and architecture, and Astera helps solve the data-movement problem between components. For Nvidia, the bull case is that NVLink can become more valuable even when Nvidia does not sell every accelerator, shifting it from dominating GPUs to controlling an important system standard, while the bear case is that NVLink Fusion deliberately makes alternative accelerators easier to deploy and could cost Nvidia some GPU unit share. For Astera Labs, heterogeneous systems may be an even cleaner opportunity, since more accelerators, memory pools, CPUs and switches create more connectivity bottlenecks for its retimers, fabric switches and other connectivity products, though its valuation already assumes substantial AI infrastructure growth. Hedge-fund positioning turned more bullish on Astera Labs in the second quarter, with 73 hedge funds tracked in the stock versus 53 in the first quarter, while Nvidia rose to 285 hedge funds from 275, and short interest stood at roughly 6.6% of Astera's float on August 14 versus about 1.2% for Nvidia, though ALAB short interest fell from the previous reporting period.

d-Matrix announced a multi-year collaboration with NVIDIA that will integrate its next-generation inference XPUs, starting with d-Matrix Raptor, directly into NVIDIA's MGX rackscale architecture via NVLink Fusion. The rack-level system is aimed at AI labs, hyperscalers, and neoclouds seeking ultra-low latency premium-level token services, and pairs d-Matrix XPUs with NVIDIA Vera CPUs, NVLink switches, BlueField-4 DPUs, ConnectX-9 SuperNICs, and Spectrum-X Ethernet networking. d-Matrix is also partnering with Astera Labs to deliver custom connectivity solutions for high-throughput data flow, and the MGX-based rack will use modular cable-free trays built on NVIDIA's proven supply chain. Raptor, a follow-on to the Corsair XPU platform, uses a first-of-its-kind 3D DRAM stacking approach that combines a DRAM memory chip and an SRAM compute chip into a single two-story package, is backed by more than 100 patents, and is expected to tape out before the end of the year. Initial availability of d-Matrix Raptor XPUs integrated into the NVIDIA MGX rack is expected in Q4 2027.

Citi told clients in a note Tuesday that it expects semiconductor stocks to rebound after a summer slump, arguing that a heavy conference schedule and resilient data center demand should support the sector. The bank noted the Philadelphia Semiconductor Index fell 18% over the summer as the group ran into high expectations and a modest deceleration in earnings momentum. Even so, Citi looks for a recovery heading into its Global TMT conference, where it expects positive commentary led by AMD, MRVL, LITE, ALAB, and semi caps. Data center demand remains strong, accounting for 34% of the industry's total addressable market, while autos and industrials, at 21%, continue to recover. Demand from PCs and handsets, which make up 42% of the market, is said to remain weak amid memory cost inflation and supply constraints. The bank turned more bullish on central processing units after recent earnings and the Hot Chips conference, lifting its CPU market forecast to $237 billion by 2030 from $29 billion in 2025, a 52% compound annual growth rate, above forecasts from AMD, Arm and Nvidia. Citi expects AMD to be the key beneficiary of what it called a "CPU renaissance," with Intel a secondary winner. Furthermore, Citi raised its outlook for wafer fabrication equipment spending, citing a stronger hyperscaler capital expenditure model, now seeing a 2028 bull case approaching $300 billion, with base-case spending of $257 billion, up from $250 billion previously.

ALAB01, a foreign securities derivative instrument of Astera Labs, rose 5.34% to 4.34 baht, driven by investment momentum in AI infrastructure that supports the underlying stock price. Asia Plus Securities research noted that the Scorpio AI Fabric Switch product is likely to become the highest revenue generator one quarter ahead of schedule, supporting Q3 revenue guidance of $540-560 million, or growth of 38-43% quarter-on-quarter. The reference target price for ALAB01 is 6.012 baht, based on an exchange rate of 32.88 baht per dollar and a conversion ratio of 1:2,300. The research house recommends accumulating on weakness, as the current price already reflects high growth expectations.

Networking is replacing raw computing power as the main constraint on artificial intelligence performance as AI systems grow larger and more complex, according to Citi analysts following the second day of the Hot Chips conference. The shift creates a particularly positive outlook for Nvidia, Broadcom, Arista Networks, Lumentum, Coherent, Marvell Technology, and Astera Labs, Citi said. The analysts noted that the first wave of AI infrastructure development focused heavily on faster GPUs, larger accelerators, and greater training capacity, but as AI systems expand toward trillions of parameters, larger context windows, and autonomous agent workloads, efficiently moving data between chips, servers, racks, and data centers is becoming a bigger bottleneck. Citi said presentations from Nvidia, Broadcom, Meta Platforms, Alphabet's Google, Samsung, and other companies pointed toward the same trend, with the future AI winner being the company that can move data most efficiently throughout the entire system. Memory is also increasingly part of the networking challenge, as technologies from Samsung, XCENA, and Cerebras aim to keep data closer to processing, reducing communication overhead. Citi highlighted Nvidia's concept of future data centers as "AI factories," designed around data flows rather than servers, which could shift more AI infrastructure value toward companies optimizing the entire data movement stack.
