Market debate has moved from whether SpaceX and Tesla will merge to when, with
some long-term investors treating a tie-up as likely. Musk has not confirmed any
deal but repeatedly refers to business integration, and SpaceX filings that hint
at the possibility of large share issuance have prompted trading speculation.
Both companies have pivoted toward AI: Tesla is focused on autonomous driving
and humanoid robots, while SpaceX acquired xAI and plans orbital data centers;
AI is expected to become SpaceX's largest revenue source beginning this year.
Commercial links have also strengthened—SpaceX has disclosed purchases of
batteries and Cybertruck vehicles from Tesla, and Tesla gained indirect SpaceX
exposure via the xAI acquisition. Musk, who dismissed merger logic a decade ago,
acknowledged in 2025 synergies among Tesla, SpaceX and xAI in solar-AI-satellite
work, which he described as critical for harvesting large-scale solar energy.
