Market Size and Growth

The global BCI market, valued at USD 1.3 billion in 2024, is projected to surpass USD 4.3 billion by 2035, expanding at a CAGR of 11.2%. This growth trajectory is fueled by the rising prevalence of neurological disorders, increasing research investments, and the commercialization of non-invasive and semi-invasive BCI devices.

Technological advancements in electroencephalography (EEG), electrocorticography (ECoG), and functional near-infrared spectroscopy (fNIRS) have improved signal accuracy and reduced latency, making BCIs more practical and user-friendly. Additionally, the growing use of AI-based algorithms to decode neural signals has enhanced the precision of brain-controlled interfaces, enabling wider adoption in medical and consumer markets.

Emerging startups and established medical device companies are collaborating with academic research centers to accelerate innovation. The next decade is expected to see a surge in hybrid BCIs combining neuroimaging, machine learning, and wearable technologies to deliver seamless connectivity between the human brain and digital ecosystems.
