Elon Musk’s mega-merger makes little business sense

On February 2nd the world’s richest man announced that SpaceX, which builds rockets and sells satellite broadband, would merge with xAI , a maker of chatbots. (He owns a majority stake in both.) SpaceX investors will get 80% of the new company, valued at $1.25trn, with the remainder going to xAI’s owners. What is Mr Musk up to? The stated rationale behind the deal is that the companies will work together to launch a fleet of data centres into space, giving xAI a big advantage in the race to develop cutting-edge models while furnishing SpaceX with a new line of business.
Some pundits consider the idea plausible. Putting AI chips into orbit provides access to solar power undiminished by the atmosphere and avoids the tortuous planning processes on land. SpaceX’s constellation of Starlink satellites can then beam the data back down to Earth.
It sounds like the stuff of science fiction, and for a while may remain just that. Putting data centres in orbit presents numerous engineering challenges. It is unclear, for example, whether the hardware they currently use can survive being repeatedly exposed to cosmic rays.
Then there is the matter of cost. Although SpaceX is able to launch things into space for far less than any competitor, doing so is still not cheap. Its new “Starship" launch system, which Mr Musk hopes will bring costs down even further, is behind schedule and has yet to reach orbit.
