Samsung Secures First Neuralink Contract for Advanced Brain Chip Production
Samsung Electronics has secured its first chip development contract from Neuralink, Elon Musk's brain-computer interface venture. This development marks another significant expansion of the Korean tech giant's manufacturing relationship with Musk-linked enterprises, positioning the foundry as a critical player in the evolving landscape of medical technology and neural interfaces.
By winning this contract, the company cements its position as a primary manufacturing partner for next-generation hardware, expanding a portfolio that increasingly bridges the gap between advanced semiconductor fabrication and cutting-edge bio-technological applications.
A New Partnership in Brain-Computer Interfaces
Samsung Foundry has commenced dedicated research and development on Neuralink's fourth-generation brain implant chip. According to recent industry reports, the complex semiconductor project carries the internal codename "O1" and is slated for manufacturing using Samsung's advanced 4nm process technology. The selection of the 4nm node highlights the strict power efficiency, thermal management, and processing density requirements necessary for a device operating directly within the human body.
The development timeline indicates that engineering teams initiated foundational work on the specialized silicon architecture in late 2025. Following initial design verification phases, fabrication of the first physical test chips officially started last month. The current roadmap outlines an objective to ship the initial batch of test chips in the first half of 2027. If these preliminary components pass rigorous functional validation and safety testing, full-scale mass production is expected to begin in the second half of 2027.
This fourth-generation chip represents a significant technological leap over previous iterations developed by Neuralink. Early generations of the hardware functioned primarily as one-way communication devices, interpreting complex neural signals from the brain and relaying those commands to external electronic interfaces.
In contrast, the new architecture is engineered specifically for true two-way communication. This capability allows the system to receive data from external applications and transmit targeted electrical impulses back to the brain to stimulate physical actions. One of the primary medical applications planned for this bidirectional data transfer involves restoring visual perception to individuals with impairment by systematically stimulating specific brain neurons.
TSMC Sidelined as Musk Deepens Samsung Ties
The awarding of this contract indicates a strategic shift in Neuralink's semiconductor supply chain, moving chip manufacturing allocations away from Taiwan Semiconductor Manufacturing Company (TSMC). TSMC was previously responsible for fabricating the third-generation Neuralink hardware. Industry analysis suggests this reallocation is driven in part by severe supply constraints at TSMC, where production lines face overwhelming capacity demands from global artificial intelligence firms, most notably Nvidia.

This manufacturing pivot builds upon a pre-existing multi-billion-dollar relationship between the executive's ventures and the South Korean tech conglomerate. The contract complements a landmark $16.5 billion multiyear agreement established with Tesla to manufacture AI6 inference chips.
Those automotive and robotics processors are designed for deployment in autonomous vehicles, humanoid robotic systems, and high-performance AI data centers. The Tesla manufacturing agreement, announced in July 2025, extends through the end of 2033 and utilizes production capacity at Samsung's advanced fabrication facility located in Taylor, Texas.
Foundry Revival Ambitions and Market Implications
For the semiconductor division, securing the Neuralink account provides a critical addition to its growing roster of high-profile foundry clients. The contract arrives at a pivotal moment as the company works to engineer a financial turnaround for a business unit that has navigated persistent operational losses. Internal corporate projections estimate that the contract manufacturing division will reverse these trends and achieve steady profitability by 2028.
To support this timeline and capture a larger share of the global market, corporate leadership has committed to investing a record 110 trillion won in chip capacity expansion and fundamental research this year. This aggressive capital expenditure strategy underscores a broader corporate push to compete directly in the highly competitive AI semiconductor era, validating their manufacturing capabilities against industry rivals.
At the same time, Neuralink continues to accelerate its clinical and operational timelines. The medical device company has already implanted its brain-computer interface systems into at least 12 patients suffering from paralysis as part of ongoing regulatory clinical trials. These medical procedures serve to validate the safety and efficacy of the hardware platforms ahead of broader commercialization.
With public declarations pointing toward the commencement of high-volume production of brain-computer interface devices in 2026, the collaboration with Samsung Foundry establishes the supply chain foundation necessary to fulfill long-term hardware manufacturing demands.
