Investors familiar with the matter told The Wall Street Journal that the rocket company SpaceX has agreed to invest a whopping $2 billion in xAI, the Musk-led firm behind the controversial large language model Grok. This investment makes up almost half of the $5 billion of equity that the AI company raised last month.

Grok 4, the AI chatbot developed by Elon Musk-owned company xAI stirred controversy last week. The AI bot referred to itself as ‘MechaHitler’, praised Adolf Hitler and made antisemitic and racist remarks in response to users’ questions.
