SpaceX acquired Cursor, a competitor to Claude Code and OpenAI’s Codex, a week after becoming a publicly traded company, according to an update on June 16, 2026. In April, SpaceX had struck a $10 billion deal with Cursor ahead of a $60 billion acquisition. The collaboration, announced in April, involved SpaceX and Cursor “working closely together to create the world’s best coding and knowledge work AI,” leveraging SpaceX’s “million H100 equivalent Colossus training supercomputer.” Cursor stated it was partnering with SpaceX to accelerate model training efforts, noting that its Composer 1.5 model scaled reinforcement learning by over 20x, and Composer 2 reached frontier-level performance at a fraction of the cost of other models, but had been bottlenecked by compute. The partnership allows Cursor’s team to use xAI’s Colossus infrastructure to scale model intelligence.
