What Would The Stop Insider Trading Act Prohibit?
The U.S. House of Representatives has approved legislation restricting members of Congress and their immediate families from buying publicly traded stocks, sending the measure to the Senate for consideration.
Lawmakers passed the Stop Insider Trading Act in a 232-198 vote on Wednesday. The bill would prohibit members of Congress, their spouses and dependent children from purchasing individual publicly traded stocks while the lawmaker remains in office.
Representative Bryan Steil of Wisconsin, who sponsored the legislation, said the restrictions were intended to prevent lawmakers from using nonpublic information obtained through their official duties for personal financial gain.
“We have not had a bill on the House floor on this topic with this opportunity before,” Steil said during the debate.
The bill would impose a fine of either $2,000 or 10% of the prohibited transaction. Violators could also be required to surrender profits earned through transactions that failed to comply with the legislation.
The measure was formally received by the Senate on Thursday. Its prospects remain uncertain because some senators and House Democrats argue that the restrictions leave lawmakers with too much freedom to manage investments they already own.
Why Are Critics Calling The Bill Incomplete?
The legislation would block new stock purchases but would not force members of Congress to sell assets already held in their portfolios. Lawmakers could continue owning those stocks and would retain the ability to sell them after providing advance notice.
Steil said members would be required to disclose a planned stock sale seven days before completing the transaction. He argued that the notice requirement would create a deterrent by allowing the public to scrutinize trades before they occur.
Critics say the structure does not eliminate the central conflict because lawmakers could still make decisions affecting companies in which they hold a financial interest.
“[The] bill has major loopholes,” Senator Elizabeth Warren said Thursday. “Lawmakers can continue owning and selling stocks — so it won’t solve the problem. Not gonna fly in the Senate. Members of Congress should not own, buy, or sell stocks.”
The dispute gives the Senate several options. It could approve the House bill, reject it or amend the legislation to require lawmakers to divest individual stocks, place assets in qualified blind trusts or face wider restrictions on selling existing holdings.
Investor Takeaway
The House vote increases the chance of federal limits on congressional trading, but the final rules may become stricter in the Senate. The main issue is whether lawmakers will only be barred from making new purchases or also required to give up stocks they already own.
Why Does The Bill Exclude The President?
The Stop Insider Trading Act applies to members of Congress, their spouses and dependent children. It does not extend the stock-trading restrictions to the president, vice president or their families.
That narrower scope differs from proposed ethics language connected to the Digital Asset Market Clarity Act. Draft provisions under consideration for that cryptocurrency market structure legislation could bar a wider group of U.S. public officials from issuing or sponsoring digital tokens until 2029.
The contrast may become part of the Senate debate. Lawmakers who support wider ethics rules could argue that financial restrictions should apply consistently across senior government officials rather than focusing only on Congress.
Supporters of the House bill may counter that a narrower measure has a better chance of passing and can establish a minimum standard without waiting for agreement on broader restrictions covering the executive branch.
Could Prediction Market Trading Face Similar Restrictions?
The House vote follows a separate proposal from Steil targeting lawmakers who trade on prediction platforms such as Kalshi and Polymarket.
The Stop Lawmakers from Predicting Act, introduced in June, would prevent certain public officials, their spouses and children from wagering on public policy questions and political outcomes. Proposed penalties would mirror the stock-trading bill, with violators facing a $2,000 fee or 10% of the prohibited wager.
Prediction markets have drawn closer scrutiny after reports of trades linked to people who may have had access to sensitive government information. One case involved a soldier accused of earning more than $400,000 from contracts tied to the removal of Venezuelan President Nicolás Maduro by U.S. forces in January.
Donald Trump’s teleprompter operator also reportedly earned more than $100,000 from event contracts linked to words and phrases used in the president’s speeches.
These cases have expanded the congressional trading debate beyond traditional stocks. Shares, tokens and event contracts can all create conflicts when government officials or employees possess information unavailable to the public.
The Senate’s handling of the stock bill may therefore shape later efforts to regulate prediction market activity by public officials. A stronger Senate version could establish the model for broader restrictions across financial markets, while rejection of the bill would leave existing disclosure rules largely intact.
