Automotive Ethernet Market Report 2026

The automotive ethernet market size has grown rapidly in recent years. It will grow from $3.4 billion in 2025 to $4.02 billion in 2026 at a compound annual growth rate (CAGR) of 18.1%. The growth in the historic period can be attributed to increasing vehicle electronics content, infotainment system complexity, early adas deployment, need for diagnostics efficiency, evolution of in-vehicle networking.

The automotive ethernet market size is expected to see rapid growth in the next few years. It will grow to $7.73 billion in 2030 at a compound annual growth rate (CAGR) of 17.8%. The growth in the forecast period can be attributed to electrification of vehicles, autonomous driving development, software-defined vehicles, demand for high-bandwidth communication, connected car expansion. Major trends in the forecast period include growth of high-speed in-vehicle networks, adoption of ethernet in adas architectures, consolidation of vehicle ecus, rising demand for lightweight cabling, expansion of doip applications.

The rising demand for motor vehicles has supported the growth of the automotive Ethernet market during the forecast period. The integration of advanced solutions such as connected devices, artificial intelligence (AI), and digital technologies in modern vehicles is accelerating innovation within the automotive industry, which in turn is increasing the need for automotive Ethernet solutions. For example, in October 2025, according to Statistics Canada, a Canada-based government agency, the number of registered road motor vehicles in Canada reached 26.8 million in 2024, representing a 4.2% increase compared to the previous year. Therefore, the growing demand for motor vehicles is expected to generate strong demand for automotive Ethernet solutions, driving market growth during the forecast period.

Major companies operating in the automotive Ethernet market are concentrating on the development of innovative technologies such as multi-gig Ethernet camera bridge solutions to address the increasing need for high-resolution, real-time video data transmission in autonomous vehicles. Multi-gig Ethernet camera bridge solutions enable high-speed data transfer between multiple cameras and electronic control units (ECUs) through Ethernet-based connectivity within automotive systems. For instance, in July 2023, Microchip Technology, a U.S.-based semiconductor manufacturer, launched automotive-qualified 10BASE-T1S Ethernet devices, including the LAN8670, LAN8671, and LAN8672 PHYs. These devices support data transmission speeds of up to 10 Mbps in half-duplex mode and enable flexible network topologies using a single balanced pair of conductors. They are AEC-Q100 Grade 1 qualified for high reliability in automotive environments and feature advanced diagnostic capabilities for network troubleshooting. Additionally, the devices support low-power operating modes and Time-Sensitive Networking (TSN) to ensure synchronized communication across automotive networks, with development tools provided to support system integration.

In October 2025, NXP Semiconductors, a Netherlands-based provider of automotive processing, networking, and connectivity solutions, acquired Aviva Links for $242.5 million in cash. Through this acquisition, NXP aims to expand its automotive Ethernet and networking capabilities by integrating ASA-based asymmetrical multi-gigabit connectivity. This strengthens NXP’s ability to deliver standardized, end-to-end in-vehicle networking solutions for advanced driver-assistance systems (ADAS), in-vehicle infotainment (IVI), and next-generation software-defined vehicles. Aviva Links is a U.S.-based company specializing in in-vehicle connectivity technologies, including automotive Ethernet.
