Several members of Congress and their immediate family members purchased shares of SpaceX shortly after the aerospace giant's blockbuster initial public offering, raising fresh concerns among ethics experts over whether lawmakers should be allowed to trade stocks in companies that rely heavily on federal contracts and government oversight.

According to a CNBC analysis of House financial disclosure filings, at least six members of the House of Representatives or their families acquired between approximately $83,000 and $245,000 worth of SpaceX stock within six days of the company's June 12 public debut.

While there is no evidence any of the transactions violated the law or relied on nonpublic information, critics argue the purchases reflect longstanding concerns about the appearance of conflicts of interest in Congress.

Among those purchasing shares was Rep. William Timmons, a South Carolina Republican who chairs a House oversight panel focused on military and foreign affairs and also serves on a House Financial Services subcommittee overseeing artificial intelligence. According to disclosure forms, Timmons purchased between $50,001 and $100,000 worth of SpaceX shares just three days after the IPO.

Other lawmakers identified by CNBC include Republicans John McGuire of Virginia, Dan Meuser of Pennsylvania and John James of Michigan, along with Democrats Gil Cisneros of California and Jared Moskowitz of Florida. Congressional financial disclosure forms report transactions in value ranges rather than exact amounts.

Several of those lawmakers sit on committees with jurisdiction over industries central to SpaceX's business, including defense, securities regulation, satellite communications and artificial intelligence. The company depends on billions of dollars in federal contracts and government approvals through agencies including NASA, the Pentagon and intelligence agencies.

CNBC noted that five of the six lawmakers who purchased shares serve on congressional committees that oversee portions of SpaceX's operations or the industries in which it operates.

The purchases were all legal under current congressional ethics rules. Members of Congress may own and trade individual stocks as long as they disclose transactions exceeding $1,000 within the required reporting period. Some of the reported purchases were made by spouses or dependent children, while several lawmakers have said outside financial advisers manage their investment portfolios.

Still, government ethics advocates argue the transactions highlight why many have pushed for stricter restrictions on congressional stock ownership. "Members are making decisions, buying and selling as if they're on Wall Street. And they're not doing it in the interest of their constituents," Rep. Pramila Jayapal, a Washington Democrat, told CNBC. "They're doing it in the interest of their pockets."

Kedric Payne, ethics director at the nonprofit Campaign Legal Center, said the issue extends beyond insider trading concerns. "The potential conflict of interest exists when the committee assignment may overlap with this company as a government contractor," Payne told CNBC.

Among the lawmakers, Rep. Gil Cisneros purchased between $1,001 and $15,000 in SpaceX shares on June 18. Cisneros serves on the House Armed Services Committee, which oversees Pentagon and Space Force programs. He previously told CNBC that he does not manage the day-to-day trading activity within his investment portfolio.

Rep. John James' wife purchased between $15,001 and $50,000 in SpaceX stock on IPO day. James serves on the House Energy and Commerce Committee, which has oversight responsibilities affecting artificial intelligence infrastructure and energy policy. A spokesperson told CNBC the investment was made on behalf of the couple's children, who are interested in space exploration.

Meanwhile, McGuire disclosed that his wife bought between $1,001 and $15,000 in shares, while Meuser reported that one of his dependent children purchased between $15,001 and $50,000 worth of SpaceX stock.

Payne argued that purchases by spouses or dependent children do not eliminate conflict concerns because congressional financial disclosure rules treat household financial interests as shared interests.

Even lawmakers without direct oversight responsibilities may face scrutiny. Rep. Jared Moskowitz, who serves on the House Judiciary and Foreign Affairs committees, also purchased shares during the IPO. Although neither committee directly regulates SpaceX, members of Congress routinely vote on defense appropriations and legislation that could affect government contractors.

The controversy comes as Congress debates new restrictions on lawmakers' stock trading.
Last week, the House approved the Stop Insider Trading Act, sponsored by House Administration Committee Chairman Bryan Steil. The legislation would prohibit future purchases of individual stocks by lawmakers while allowing them to retain current holdings, reinvest dividends and sell existing positions with advance public notice.
