Signal Brain-computer interface market projected to quadruple by 2034

Summary

This signal tracks the commercial growth of brain-computer interfaces, which let people control external devices directly through neural activity. The global market for these interfaces is projected to rise from US$3.21b in 2025 to US$12.87b by 2034, roughly a fourfold increase. EY describes the technology as still in early development but as the ultimate frontier of human augmentation. China is named as a significant competitor, with companies demonstrating robotic manipulation controlled by the brain and clinical implementations of the interfaces. EY also points to emerging regulation of neural data, which will test how far existing privacy and intellectual property rules can stretch. Growth of the market therefore brings questions of data ownership and mental privacy along with it.
