SpaceX approached AI coding startup Cognition about an acquisition, Bloomberg reports, and Cognition did not engage. Chief executive Scott Wu replied publicly that his company is “not for sale and we haven’t been talking.”

SpaceX approached the AI coding company Cognition about buying it, according to Bloomberg, and Cognition did not engage. It would have been the company’s second large AI takeover in a matter of months.

The denial arrived the same day and went further than the report. Chief executive Scott Wu wrote publicly that Cognition is “not for sale and we haven’t been talking.”

Those two accounts are close but not identical. Bloomberg describes an approach that was not taken up, alongside continuing discussions about working together, including a possible arrangement for Cognition to use SpaceX’s computing capacity.

Cognition is not cheap either way. It raised $1bn at a $26bn valuation in May and has been in early talks with investors this month at a valuation of at least $40bn.

The context is what SpaceX bought last week. It completed a $60bn purchase of Cursor on 14 August, the largest name in the vibe coding market.

Buying a second one so quickly says something about the first. SpaceX’s AI arm has trailed rivals in selling to businesses and has been through job cuts and restructuring.

Cognition would have arrived with customers attached. Its Devin agent is used by Mercedes-Benz and GE Aerospace, and Bloomberg reports that its commercial progress interested SpaceX as much as its technology.

Elon Musk has set the pace himself. He told staff that AI revenue would out-earn rockets by September, a target that requires enterprise customers rather than research prestige.

The compute talks are the part worth watching. If Cognition ends up renting SpaceX’s GPUs, a company that refused to be bought becomes dependent on the infrastructure of the company that tried.

Wu has said this before, which matters when reading the denial. He told Bloomberg in May that the round he had just closed was what allowed Cognition to “stay independent and continue as an independent business.”

For European developers the direction is the story rather than the deal. The tools their engineering teams now depend on are being gathered into an American conglomerate that also launches rockets and runs a satellite network.
