Elon Musk's various companies are pursuing an unusually dense slate of new technology projects in 2026, spanning space exploration, brain-computer interfaces, humanoid robotics and semiconductor manufacturing. Here are five of the most significant technologies currently in development across his business empire.

The first is Neuralink's push to scale brain-implant production and restore vision for blind patients. Musk has said Neuralink plans to move toward high-volume production of its brain-computer interface device in 2026, alongside a transition to a nearly fully automated surgical implantation procedure, following the company's earlier regulatory clearance. As of September 2025, twelve patients worldwide had received Neuralink implants, and the company has continued expanding its clinical trial participant registry, including accepting applications from Canada, with expansion into the United Kingdom under evaluation. Separately, Neuralink's Blindsight implant, designed to restore a form of vision for people who are completely blind by using ultra-fine threads to stimulate the visual cortex and generate perceptions of light and shapes, is set for its first patient trial in 2026, a milestone the company has described as a significant step toward using brain-computer interfaces to address sensory disability.

The second major project is SpaceX's development of its next-generation Starship V3 spacecraft. The upgraded vehicle, featuring SpaceX's new Raptor V3 engine, is expected to conduct propellant transfer tests in orbit during 2026, a capability........
