Despite their impressive ARR, Cursor faces existential threat from not only BigLabs (Claude Code, Open AI Codex) but also BigTech (AWS Kiro, Google Antigravity, MS VSCode). I am sure the usual suspects would have lined up to purchase Cursor, and the deal from xAI was probably the best of the lot. Marks an end to a remarkable sprint for a 3yo company, and an admirable exit (considering the recent discombobulation of Windsurf's), just as investor money and/or hype is going belly up.
