Two xAI Co-Founders Exit in 48 Hours, Leaving Half the Founding Team Gone

Musk says a reorganization following SpaceX’s acquisition required parting with staff to speed execution.

Overview

  • Yuhuai (Tony) Wu and Jimmy Ba announced departures on X within a day of each other, bringing total co-founder exits to six of the original 12.
  • Musk acknowledged the turnover and confirmed xAI was reorganized to increase execution speed, adding that the company is hiring aggressively.
  • The resignations arrived days after SpaceX acquired xAI in an all-stock deal reported to value SpaceX at about $1 trillion and xAI at roughly $250 billion, with a public listing targeted for 2026.
  • xAI faces ongoing regulatory scrutiny after Grok-enabled image tools were used to create nonconsensual explicit content, including a Paris office raid and multinational probes.
  • Recent reporting cites internal friction over demands to improve model performance, while multiple non–founder departures have also thinned technical and legal ranks.
