The claim, plainly

Neuralink's brain-computer interface device is operating reliably in seven human clinical trial participants.

Assessment

The claim made by then-Neuralink co-founder DJ Seo on June 28, 2025, stated that Neuralink's device was operating reliably in seven human clinical trial participants. Independent and institutional records corroborate this claim as of that date. On June 28, 2025, trial partner Barrow Neurological Institute confirmed that seven individuals had received N1 implants and were actively using them. Independent reporting detailed the chronological roster of seven participants up through June 2025 (Noland Arbaugh, Alex, Bradford G. Smith, Mike, RJ, Rob Greiner, and a seventh participant). Subsequent trial data and reporting in September 2025 corroborated that the cohort had reached seven by late June 2025 before expanding further.

On June 28, 2025, clinical trial partner Barrow Neurological Institute confirmed seven individuals with severe paralysis had received Neuralink N1 implants and were actively using them.
Documentation by PCMag (June 28, 2025) and R&D World (June 30, 2025) verified seven implanted patients actively using the devices by late June 2025.
Subsequent reports by Reuters and The Hindu on September 10, 2025, confirmed the cohort grew from the baseline of seven patients recorded in June 2025 to 12 patients worldwide.

Seo: Neuralink has implanted a locked-in late-stage ALS patient

“One of our participants is in what's called a late-stage ALS, which means that he's effectively locked in, so unable to move, unable to speak even, and is connected to a mechanical ventilator to basically keep him alive.”
