TER Rides on Strong AI Infrastructure Demand: A Sign for More Upside?

Teradyne TER is benefiting from the surging demand for AI infrastructure, which has become a major growth driver for the company. In the fourth quarter of 2025, the company highlighted that AI-driven applications accounted for more than 60% of its revenue, up from 40% to 50% in the third quarter of 2025. This trend is expected to continue, with AI applications projected to drive up to 70% of revenues in the first quarter of 2026. The company’s focus on AI is driving robust growth across its semiconductor test and robotics divisions.

The company’s expanding portfolio has been noteworthy. In January 2026, Teradyne announced that it would form a majority-owned joint venture with MultiLane, called MultiLane Test Products, to accelerate development of high-speed test solutions for the growing AI data center market, with the deal expected to close in the first half of 2026. 

Teradyne’s acquisitions have played a crucial role in its success. The integration of Quantifi Photonics into its Product Test Group has expanded its capabilities in silicon photonics device testing, aligning with the growing demand for AI data center infrastructure.

Teradyne anticipates robust year-over-year growth in 2026 in the semiconductor test market, driven by AI compute and memory demand, as well as moderate recovery in auto/industrial applications. The robotics segment is also expected to benefit from the increasing adoption of physical AI and advanced robotics in e-commerce and logistics.

Teradyne Suffers From Stiff Competition

Teradyne is facing stiff competition from the likes of Advantest Corporation ATEYY and KLA KLAC. Both Advantest and KLAC are expanding their footprints in the AI infrastructure space.

Advantest is expanding its footprint in the semiconductor test market by focusing on the growing demand for AI-related high-performance semiconductors, such as high-performance computing devices and high-performance DRAM for data centers.

KLA is benefiting from the growing demand for AI infrastructure through its leadership in process control and its ability to address growth markets in wafer fab equipment, including high-bandwidth memory and advanced packaging. The company is expected to benefit from the expansion of the core wafer fab equipment market, which is forecasted to grow in the high single to low double digits in 2026. The advanced packaging market is also projected to grow at a similar rate, reaching approximately $12 billion. KLAC is also poised to capitalize on several industry trends, including the rising demand for AI infrastructure, the growth of advanced packaging, and the increasing semiconductor content across diverse end markets.
