S. 4134

Congressional Research Service summary, version: Introduced in Senate (Mar 18, 2026)

Stop Insider Trading Act

This bill generally prohibits Members of Congress and their spouses and dependent children from purchasing stocks and requires public notice before these individuals may sell stocks.

Specifically, Members of Congress and the spouses and dependent children of Members may not purchase covered investments. Between 7 and 14 days before a Member or a covered spouse or dependent sells a covered investment, the relevant Member must file a public notice of the intent to sell with the Clerk of the House of Representatives or the Secretary of the Senate, as appropriate. The Clerk or Secretary must publish this notice online. If the individual decides not to sell the investment, the notice must be withdrawn.

Under the bill, a covered investment is a security issued by a publicly traded company or a related instrument (e.g., a derivative). Some investments are exempt, including interest in a widely held investment fund and certain investments held in a trust.

Violations of these provisions are subject to a fee and, in the case of a purchase, a requirement to sell the covered investment. The fee equals the sum of (1) the greater of $2,000 or 10% of the transaction value, and (2) any net gain from the transaction during a specified period. The fee may not be paid using campaign donations or Members’ official allowances.

Certain transactions by covered spouses and dependents are exempt, including transactions made on behalf of another person or made as part of compensation from the individual’s employer.
