PCIe Switches Market: AI Infrastructure Shifts Demand Toward Higher-Speed Switching

The Global PCIe Switches Market was valued at USD 2.50 billion in 2025 and is projected to reach USD 6.10 billion by 2032, expanding at a CAGR of 13.2% during 2026–2032.

 

A PCIe (Peripheral Component Interconnect Express) switch is a hardware logic device designed to expand a single host connection into multiple downstream ports. It enables a CPU to connect with several high-speed endpoints such as GPUs, NVMe solid-state drives, and network interface cards through a low-latency switching fabric, effectively overcoming the direct lane limitations of a standard processor.

 

Demand for PCIe switches is increasing due to several converging technology trends. The rapid expansion of artificial intelligence and machine learning workloads has created a need for large multi-GPU clusters that require extremely low latency and high-bandwidth data exchange. At the same time, modern data centers are scaling through disaggregated architectures that dynamically allocate compute, storage, and networking resources, further increasing reliance on flexible interconnects. Advancements in PCIe standards, including Gen 5 and Gen 6, are also driving adoption by delivering significantly higher throughput and improved power efficiency for enterprise and hyperscale workloads. In addition, the automotive and Internet of Things sectors are contributing to demand, as advanced driver-assistance systems in vehicles and edge devices require high-speed internal data processing and real-time communication between multiple electronic subsystems.

 

AI Servers Increase the Need for PCIe Switching

Data centers accounted for 46.0% of market revenue in 2025, or USD 1.15 billion, and are expected to reach USD 3.11 billion by 2032 (15.28% CAGR). Growth is driven by AI servers that combine GPUs, NICs, and high-speed storage in dense configurations, increasing the need for PCIe switches to manage internal connectivity and expand available processor lanes.

Major cloud providers are scaling infrastructure spending to support this shift. Alphabet reported USD 44.9 billion in Q2 2026 capital expenditure, with most directed toward servers and networking. Microsoft expects about USD 190 billion in 2026 capex, largely tied to AI-optimized server deployments, while Meta raised its 2026 outlook to USD 125–145 billion for large AI training clusters. These investments continue to drive demand for high-bandwidth PCIe switching inside modern data-center systems.

 

Gen4 Leads Today While Gen5 and Gen6 Reshape New Designs

PCIe Gen4 held the largest share at 46.0% in 2025 (USD 1.15 billion) and remains widely used in servers, networking, and embedded systems due to its balance of performance and cost. PCIe Gen3 continues to serve legacy and cost-sensitive applications, but its 1.87% CAGR reflects gradual decline as hyperscale operators such as Amazon Web Services and Microsoft Azure transition away from Gen3-based server architectures toward higher-bandwidth systems.

PCIe Gen5 is the fastest-growing segment, rising from USD 0.60 billion in 2025 to USD 2.928 billion by 2032, reflecting a strong 25.41% CAGR, driven mainly by AI servers and high-performance computing that require higher bandwidth between CPUs, GPUs, and storage. This growth is reinforced by deployments from companies such as NVIDIA, which integrates Gen5/Gen6-ready interconnects in its HGX and GB200-class AI platforms, and AMD, whose EPYC server ecosystems increasingly support Gen5 lanes for accelerator-heavy workloads, enabling higher data throughput for large-scale AI training and inference clusters.

Beyond Gen5, the market is already transitioning toward Gen6. Broadcom introduced a full PCIe Gen6 portfolio in 2025, while Microchip’s Switchtec Gen6 switches support up to 160 lanes and 20 ports, signaling early enterprise adoption. Astera Labs also reported USD 392.4 million in Q2 2026 revenue, with its Scorpio fabric switches emerging as a key growth driver as AI infrastructure scales.

 

Data Centers Dominate While Automotive and Cloud Platforms Broaden Demand

Enterprise IT accounted for 23.0% of the market in 2025 (USD 0.575 billion) and is projected to grow at 9.68% CAGR. Growth is steady but slower than data centers due to longer server refresh cycles and lower accelerator density. However, enterprise upgrades are gradually increasing PCIe demand as vendors like Dell Technologies and HPE roll out newer server platforms designed for AI workloads and higher storage bandwidth.

Automotive and industrial automation held 14.0% share in 2025 and is expected to grow at 14.72% CAGR. Demand is rising as vehicles shift toward centralized computing systems that integrate sensors, cameras, and AI processors. Companies such as Tesla and NVIDIA (DRIVE platform) are driving this transition, while suppliers like Microchip are seeing stronger adoption of PCIe switching in ADAS and industrial robotics where multiple high-speed data streams must be connected.

Telecommunications accounted for 17.0% of 2025 revenue and is projected to grow at 12.61% CAGR. Growth is supported by 5G and edge computing deployments, where disaggregated network architectures require higher internal data movement between processors, storage, and acceleration hardware. Vendors such as Ericsson and Nokia are increasingly deploying such architectures, raising demand for PCIe-based connectivity inside telecom infrastructure.

At the end-user level, cloud service providers dominated with 38.0% share in 2025 and also show the fastest growth at 16.37% CAGR. OEMs and ODMs accounted for 29.0%. Hyperscalers such as Amazon Web Services, Microsoft Azure, and Google Cloud are rapidly expanding AI server deployments, which require dense GPU, storage, and networking interconnects. This directly increases demand for high-lane PCIe switch architectures across large-scale data center environments.

 

North America Leads While Asia Pacific Gains Faster

North America held the largest regional share at 39.0% in 2025, valued at USD 0.975 billion, with a CAGR of 13.0%. This leadership is driven by major cloud and AI infrastructure players such as Alphabet, Microsoft, and Meta, which are rapidly expanding AI data centers. Their investments increase demand for PCIe switches to support higher GPU density, storage connectivity, and networking bandwidth in AI server architectures.

Asia Pacific accounted for 33.0% of the market in 2025 and is the fastest-growing region with a CAGR of 15.90%. Growth is led by Taiwan’s strong role in AI server manufacturing and system integration. Companies like Foxconn are deploying NVIDIA-based AI server racks such as Vera Rubin NVL72, which require dense high-speed interconnects. Astera Labs also expanded its interoperability operations in Taiwan in 2026 to support increasing system complexity and deployment scale.

Europe represented 22.0% of market revenue in 2025, with a CAGR of 12.5%. Growth is supported by public investment in AI and high-performance computing. EuroHPC is developing 19 AI Factories and 13 AI Factory Antennas and has procured 12 supercomputers, all of which require scalable internal connectivity to support multi-accelerator computing environments and high-speed data movement.

LAMEA accounted for 6.0% of the market in 2025, with a CAGR of 10.8%. Demand remains limited but is gradually increasing, mainly driven by telecom modernization, early cloud adoption, and selective high-performance computing deployments rather than large-scale hyperscale infrastructure.
