Which Members of Congress Own xAI?
As of October 29, 2026, one member of Congress has disclosed a trade in xAI, Elon Musk's AI company and the maker of Grok: Rep. Lisa McClain (R-MI) reported a $100,001 - $250,000 purchase in a spouse's account, dated December 15, 2025, while xAI was still private. xAI is no longer a separate company: SpaceX acquired it in an all-stock deal on February 2, 2026, and SpaceX has traded on Nasdaq as SPCX since June 12, 2026.
Key numbers
- One member of Congress has disclosed a trade in xAI: Rep. Lisa McClain (R-MI), a purchase of $100,001 - $250,000 in a spouse's account dated December 15, 2025 (STOCK Act reports filed through October 29, 2026).
- Lisa McClain's xAI purchase was reported as private stock on a report filed January 7, 2026, 23 days after the trade date, inside the STOCK Act's 45-day limit.
- xAI stopped being a separate company on February 2, 2026, when SpaceX acquired it in an all-stock deal; SpaceX began trading on Nasdaq as SPCX on June 12, 2026, so xAI's business is now part of a listed company.
- Lisa McClain also disclosed buying SpaceX while it was private, a purchase of $100,001 - $250,000 dated September 12, 2025; 7 members of Congress in all have disclosed SpaceX or SPCX trades (STOCK Act reports filed through October 29, 2026).

What happened to xAI
xAI was founded by Elon Musk in 2023, released the Grok chatbot, and in 2025 absorbed X (formerly Twitter). Until 2026 it was a private company with no ticker, so its shares changed hands only through private rounds, secondary sales and pooled pre-IPO vehicles. On February 2, 2026 SpaceX acquired it in an all-stock deal, which made xAI part of SpaceX rather than a company of its own. When SpaceX listed on June 12, 2026, xAI’s business came with it. There is no separate xAI stock to report today; a member who wants to disclose exposure to it would now report SPCX.
The same household’s SpaceX stake
Lisa McClain also reported buying SpaceX before its IPO, a purchase dated September 12, 2025. The two private stakes were in separate companies when they were reported; since the February 2026 deal both sit in the same one. The full SpaceX record, including the members who bought SPCX after it listed and how those purchases moved against the S&P 500, is in which members of Congress own SpaceX.
Why the xAI trade has no return figure
Coldpine measures each disclosed purchase against the S&P 500 over the 90 days after the trade, from the closing price on the trade date. That needs a public market price, and xAI had none when it was bought or at any point before the merger, so the trade is listed here but not measured. How the measure works is set out in the methodology. Each amount is a reported range, not a position size or a profit, and a spouse’s or dependent child’s trades are reported alongside the member’s own; how often that happens across Congress is in spouse and child trades.
