Signals Intelligence Market Growth & Trends

The global signals intelligence market size is estimated to reach USD 28.51 billion by 2033, expanding at a CAGR of 5.5% from 2026 to 2033, according to a new report by Grand View Research, Inc. The increasing cross border tensions and the advent of natural language processing (NLP) are driving the market’s growth. NLP is making it increasingly efficient to decode the intercepted signals, leading to rising applications in intelligence, surveillance, and reconnaissance (ISR).

The COVID-19 pandemic had a mixed impact on the SIGINT market. The increased demand for situational awareness to track the pandemic's spread, manage resources, and monitor potential threats. Rising cybersecurity concerns, such as the spread of misinformation and cyberattacks, led to the need for SIGINT. Despite this demand, supply chain disruptions had a negative impact on the market growth.

The increase in terrorism globally has posed significant challenges to national and international security apparatus. The utilization of SIGINT in counterterrorism efforts enables authorities to monitor and track the activities of terrorist networks, identify key operatives, uncover their communication networks, and preemptively disrupt their plans. Some of the countries facing terrorism at large are Afghanistan, Nigeria, Yemen, Democratic Republic of Congo, and Ethiopia.

In addition, the evolving regulatory landscape and increasing emphasis on data privacy and compliance are shaping the dynamics of the SIGINT market. Stricter regulations regarding the collection, storage, and usage of intercepted data are driving innovation in SIGINT technologies to ensure compliance while maintaining effectiveness in intelligence operations.

Signals Intelligence Market Report Highlights

Based on solutions, the airborne segment led the market with the largest revenue share of 40.3% in 2025 and is expected to retain its position over the forecast period. This can be attributed to the increasing demand for effective communication interception. The cyber segment is expected to witness the fastest CAGR over the forecast period, led by the rising number of cybercrimes and the penetration of digital devices in people's lives
Based on type, the electronic intelligence (ELINT) segment dominated the market in 2025 and is also expected to grow at a significant CAGR over the forecast period. This can be attributed to the proliferation of advanced electronic warfare systems, unmanned aerial vehicles (UAVs), and other sophisticated military technologies by potential adversaries
Based on mobility, the portable segment is expected to witness the fastest CAGR during the forecast period, owing to the enhanced maneuverability, enabling operators to quickly reposition and adapt to changing mission requirements or operational environments
In November 2025, Thales Group received two PERSEUS awards from the French Navy and defense authorities for its innovations in electronic warfare and AI-enabled intelligence systems. The awards recognized CURCO, a compact radar detection payload for real-time electromagnetic spectrum monitoring, and Golden AI, an advanced tool that accelerates analysis of electronic support measures data. These solutions improve threat detection, situational awareness, and decision-making in contested electromagnetic environments. The recognition further establishes Thales as a leader in next-generation EW and SIGINT technologies for modern defense operations.
