SpaceX completes its acquisition of Cursor, which says it will have access to the SpaceX GPU fleet and points to Grok 4.6 as an early result

Sources: primary, discussion
Summary: Cursor published a first-party post on 2026-08-14 stating that the SpaceX acquisition has closed. The post says Cursor will have access to what it calls the largest fleet of GPUs in the world, which is stated access rather than a stated migration onto that fleet, and it names Grok 4.6 as an early look at what the two can now build together. The post dates the process to a partnership announced in April, while this archive covered the $60B acquisition announcement on 2026-06-16 with the regulatory review and close open. That date discrepancy is unresolved here.
Why it matters: The post ties Cursor's model roadmap to SpaceX compute and to Grok rather than to third-party frontier models.
