Rep. Lisa McClain, one of the top House Republican leaders, is looking to profit from her family’s investment. space x She made her record debut after her husband bought Elon Musk’s artificial intelligence company xAI for a whopping $250,000 before it was sold to a rocket maker.
McClain, R-Mich., the fourth-ranking Republican in the House and chairman of the House Republican Conference, disclosed his spouse’s Dec. 15 purchase in his Jan. 7 Congressional Financial Report. The value of this transaction was between $100,001 and $250,000.
CNBC found no other similarly clear direct congressional stakes in SpaceX or other tech initial public offerings expected from companies like OpenAI and Anthropic, but tracking ownership in private companies through spouses, trusts, LLCs and venture funds can be difficult.
The investment was tied to SpaceX in February when Musk split the xAI startup into a rocket and satellite company. SpaceX launched its IPO at $150 per share, raising about $75 billion and giving the company a market cap of more than $2 trillion.
For McClain’s family, the potential benefits are significant. If the xAI stock were converted into SpaceX stock, the investment could generate a paper profit of up to $150,000, according to market tracking estimates based on SpaceX’s market capitalization on Friday, the equivalent of nearly one year’s worth of McClain’s $174,000 legislative compensation.
“Chairman McClain’s investments are a matter of public record,” House Republican Conference communications director Joe Buccino told CNBC in a statement. “They are drafted in line with all House of Commons legislation and applicable law.”
The potential payday comes after a series of events that have already drawn scrutiny.
Days after McClain’s husband, Michael, bought xAI stock in December, the Department of Defense announced plans to integrate xAI’s Grok model into GenAI.mil, a Department of Defense platform designed to help military personnel use generative AI tools.
In January, Secretary of Defense Pete Hegseth announced a broader expansion of Grok’s role within the Pentagon, including access to sensitive Pentagon networks. A few weeks later, Musk integrated xAI into SpaceX.
There is no evidence that Ms. McClain knew about the Department of Defense’s xAI program before the purchase, that she was involved in those decisions, or that she or her husband used nonpublic information to make transactions. She does not serve on any parliamentary committees that oversee defense or technology. Members of Congress are allowed to own individual stocks and personal investments as long as they comply with disclosure rules and do not trade on confidential information.
“I can say with 100% certainty that we didn’t have insider information, because if we had, we wouldn’t have bought 100,000 shares, we would have bought a lot more shares,” McClain said in a January interview with NewsNation when asked about the trade.
SpaceX’s public debut comes as Musk and his company have become increasingly important players in Republican politics and federal contracting.
The company’s political donations have also shifted sharply to the right. From January 2025 to March 2026, the PAC gave 89% of its $1.4 million in donations to Republicans, according to a CNBC analysis of Federal Election Commission records and open secrets. About 5% went to Democrats, and the rest went to bipartisan groups and committees with no clear partisan leanings.
This is a departure from the 2024 cycle, when SpaceX’s political action committee distributed its funds more evenly, sending 62% to Republicans and 37% to Democrats.
SpaceX PAC is funded by employees and executives, not corporate treasuries. This is separate from Musk’s personal political work, where he has poured millions of dollars into Republican super PACs tied to Republican campaigns in the House and Senate.
SpaceX did not respond to a request for comment.
