K2 Space

K2 Space builds large high-power satellite buses — its Mega Class generates around 20kW with a 100kW Giga Class planned — able to carry heavy payloads including compute and communications hardware. It does not build an AI data center product itself but supplies the platform that power-hungry orbital compute payloads need. It launched its first Mega Class satellite in March 2026 and reports around $500M in signed contracts.

Ecosystem functionSells the chassis the whole category depends on — orbital compute is power-limited before it is chip-limited, and almost nobody else builds buses at this power class.
