One search on 6 November found press reports of SpaceX's acquisition of xAI announced on 2 February 2026, matching the date already recorded; nothing new was added from them. On 6 November 2026 the Daily Star's report of the deal (citing Reuters) was read again: \"The transaction values SpaceX at $1 trillion, and xAI at $250 billion, according to a person familiar with the matter\", and Wikipedia's SpaceXAI article gives the same figures, so the $250B price SpaceX paid is recorded as the valuation. Wikipedia also says SpaceX listed its shares in June 2026; xAI's status is kept as acquired, as in the Cursor listings' file for the same parent. No valuation is recorded: the $250B figure for the SpaceX deal comes from a person familiar with the matter as reported, not from either company (6 November 2026).",
