Musk businesses SpaceX and xAI to merge and form ‘innovation engine’

Two of Elon Musk’s key businesses, SpaceX and xAI, are to merge as the tech mogul consolidates his business interests. Experts suggest the merger will create the world’s most valuable private company.

Operating across space and satellites, SpaceX has become one of the most well-known aerospace businesses. Its Starlink constellation of low-earth orbit (LEO) satellites is becoming increasingly valuable as a global connectivity provider, with multiple airlines signing deals for inflight WiFi through Starlink. xAI, meanwhile, is best known as the operator of the AI chatbot Grok, which has hit the headlines for generating explicit material and incorrect statements.

Estimates currently value xAI at US$125 billion, and SpaceX at US$1 trillion. A statement signed by Musk and shared on the SpaceX website said:

SpaceX has acquired xAI to form the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform.

The post adds that ‘space-based AI’ and ‘orbital data centres’ will be the focus of the merger. Musk explains:

My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute [sic] will be in space. This cost-efficiency alone will enable innovative companies to forge ahead in training their AI models and processing data at unprecedented speeds and scales, accelerating breakthroughs in our understanding of physics and invention of technologies to benefit humanity.

He notes that the project will eventually involve factories on the Moon and expansion throughout the Universe, a cherished personal goal for Musk who has long nurtured the idea of establishing human civilisation on Mars.

SpaceX has proven to be an incredibly disruptive force in the aerospace world. Its dominance has forced its rivals Airbus, Leonardo, and Thales, to merge their aerospace operations in a bid to establish a credible European alternative to the Texas-based giant. While Elon Musk loves to make big promises, it can’t be denied that SpaceX, as well as his other companies including xAI and Tesla, have been incredibly impactful on their respective industries. What comes from merging his AI and aerospace businesses, whether it’s data centres in space or the promised factories on the Moon, will be eagerly anticipated across the industry.
