The terahertz technology market size was valued at US$ 736.01 million in 2024 and is expected to reach US$ 2500.55 million by 2031; it is estimated to record a CAGR of 19.2% from 2025 to 2031.

The terahertz technology market is segmented into five major regions-North America, Europe, Asia Pacific (APAC), the Middle East & Africa (MEA), and South & Central America. North America dominated the market in 2023, followed by Europe and APAC, respectively. The terahertz technology market in APAC is segmented into China, India, Japan, Australia, South Korea, and the Rest of APAC. Terahertz technology applications are in the early commercialization phases in the region's developing economies. Countries such as China, India, and Japan are progressively taking measures to stimulate the adoption of terahertz technology, such as investments in R&D, which are propelling the demand for terahertz-based products in the region. One of the primary elements fueling the adoption of terahertz technology is an increase in product innovations. The presence of leading market players offering innovative terahertz-equipped security scanning and surveillance devices also contributes to the adoption. For example, Digital Barriers excels in THz sensing technologies, involving the operation of sensing products in a variety of environments. Waves of THz have an inherent disadvantage in being affected by warm and humid environmental conditions. By developing its sensing modules to be able to be used in warmer parts of the globe, Digital Barriers has been able to overcome these challenges. In February 2024, China Mobile launched "the world's first 6G experiment satellite". The groundbreaking launch of what it claims to be the world's first 6G experimental satellites marks a significant step in the nation's pursuit of leadership in next-generation communication technologies. The state-owned telecom giant successfully deployed two satellites into low-Earth orbit (LEO), with one featuring a 6G architecture developed in collaboration with the Chinese Academy of Sciences Innovation Academy for Microsatellites and the other utilizing China Mobile's existing 5G technology. This milestone underscores the region's commitment to pioneering terahertz-based innovations, which are expected to play a critical role in 6G networks. As countries in the region, particularly China, invest heavily in cutting-edge research and development, the terahertz technology market is poised for substantial growth, driving advancements in communication infrastructure and solidifying the region's position as a global leader in emerging technologies
