Bill Ackman joins Elon Musk and Jeff Bezos in funding brain‑computer interface (B. C. I.) startups.

His Pershing Square and the newly founded Ackman Oxman Institute led a $250 million round for Precision Neuroscience, valuing the New York‑based firm at just over $1 billion. Precision’s Layer 7 device is an ultrathin film with 1,024 electrodes that sits atop the cerebral cortex, offering a less invasive alternative to Neuralink’s deeper implants. B.

C. I. technologies aim to help paralyzed patients control computers or prosthetics through thought. While Precision gained FDA clearance for short‑term implants in 2025, permanent approval may take years.

The broader B. C. I. market has attracted massive investment, with Neuralink valued near $42 billion and competitors like Synchron backed by Bezos and Gates.

Executives see a link between brain research and advancing artificial intelligence, though the field remains experimental and high‑risk.
