US-based startup Besxar is prototyping semiconductor wafer production in space by utilizing SpaceX Falcon 9 rocket boosters. As a private company, Besxar is not listed on any stock exchange. The venture aims to use the vacuum of space to manufacture high-purity chips, though it faces significant technical and economic hurdles before commercial viability.
Besxar, a US-based startup founded by former OpenAI employee Ashley Pilipiszyn, is attempting to move semiconductor manufacturing from traditional ground-based cleanrooms to the environment of space. The company aims to use the ultra-high vacuum found in orbit to produce high-purity wafers, potentially removing the need for the massive infrastructure and contaminant-control systems required on Earth.
The SpaceX Partnership
Besxar has secured an agreement with SpaceX to use its Falcon 9 rocket boosters as a testing ground for its manufacturing technology. In July 2026, the startup successfully launched two experimental units, known as 'Fabships,' aboard a SpaceX Starlink mission. These canisters were designed to test the feasibility of manufacturing semiconductor samples in microgravity and vacuum conditions. The primary goal of these missions is to de-risk the hardware and process before the company attempts to transition to larger, more permanent orbital platforms.
Business Model and Financial Context
Unlike traditional semiconductor manufacturers that trade on public stock exchanges, Besxar is a private company. It has raised approximately $14 million in funding, including a $9 million seed round from venture capital investors such as Bee Partners and Union Labs. Because the company is private and based in the United States, its shares are not available for trading on Indian stock exchanges like the NSE or BSE. For observers of the space and technology sectors, the company represents an emerging attempt to commercialize orbital manufacturing, rather than a direct stock market opportunity.
Technical and Economic Challenges
The path to commercial orbital chip production is complex. The technology relies on the premise that space provides a cleaner, more stable environment for wafer production than terrestrial facilities. However, the company faces substantial operational and financial hurdles. The most significant of these is the cost of space transportation. Currently, launching payloads remains expensive, and for space-manufactured semiconductors to compete with Earth-made chips, the cost to launch per kilogram must fall significantly.
Additionally, the engineering challenges are immense. Besxar must prove that wafers can withstand the vibrations of rocket launches and the stresses of reentry to Earth without degrading. There is also the logistical issue of returning finished products from orbit in high volumes, which requires reliable and frequent launch-and-recovery services. As the space industry matures, the company’s progress will depend on the successful development of next-generation, high-capacity launch vehicles, such as SpaceX's Starship, which could provide the necessary scale to make this business model economically viable.
