How You Can Find Out Exactly What Lawmakers Are Investing In

Curious about where lawmakers invest their money? Politicians’ investment choices often attract attention because of their unique position in shaping policy. In fact, a 2024 report by the trading platform Unusual Whales found that more than 20 members of Congress earned nearly double the S&P 500’s average gain.

Thanks to the Stop Trading on Congressional Knowledge (STOCK) Act, the public can see what members of Congress are investing in. But how do you actually find this information? And what can it tell you about market trends or potential conflicts of interest? 

What Is the STOCK Act and Why Was It Passed?

The STOCK Act was passed in 2012 following high-profile reports of lawmakers making well-timed trades around major economic events, such as the 2008 financial crisis. It was designed to boost transparency and restore public trust. The law requires members of Congress and senior federal officials to disclose any securities transaction over $1,000 within 45 days of the trade. These disclosures cover politicians, as well as their spouses and dependent children.

It’s important to note that insider trading by members of Congress is prohibited under federal securities law, just like it is for everyone else. The STOCK Act reaffirmed this prohibition and made clear that lawmakers can’t use nonpublic information gained through their official duties for personal financial gain. However, proving insider trading requires demonstrating that someone knowingly used material, nonpublic information. That’s a high legal bar, which is one reason there haven’t yet been any prosecutions under the STOCK Act.

After reported outsized gains by senior White House officials and members of Congress just before major tariff announcements in April 2025, the push to ban securities trading altogether by those in Congress gained new momentum, with Senators Mark Kelly and Jon Ossoff reintroducing their Ban Congressional Stock Trading Act in May 2025.

Where To Look Up Congressional Stock Trades

So, how can you get information on what politicians are buying and selling? Here are several options:

• Official disclosure portals: The U.S. House of Representatives and Senate both maintain searchable online databases. Here, you can look up individual lawmakers’ financial disclosures, including all reported stock trades. Just enter a name, date, or transaction type, and you’ll find detailed records.
• Third-Party Trackers: Several third-party tools have emerged to make tracking even easier. Sites like Smart Insider, Quiver Quantitative, and InsiderFinance aggregate and analyze congressional disclosures, letting you search by politician, stock, or sector. These platforms often highlight recent trades, show which lawmakers are most active, and even track the performance of stocks favored by Congress.

What To Consider When Using This Data

Congressional trades are disclosed after the fact—often 45 days later or more—so you’re seeing moves that may already be reflected in prices. In 2023, Business Insider identified 78 members of Congress who violated the law, highlighting enforcement gaps. As such, you should treat these disclosures as just one piece of your research puzzle, not a shortcut to guaranteed profits or market timing.

In addition, not every politician is an expert investor, and many hold portfolios riskier than most professionals would recommend. Following these trades too closely can expose you to unnecessary volatility or lead you to overlook your own financial goals. Always balance congressional data with your personal risk tolerance, time horizon, and a diversified investment approach.

The Bottom Line

The STOCK Act provides important access to what lawmakers are buying and selling. While tracking these moves can offer insights into emerging sectors or companies that may be in the regulatory spotlight, remember that disclosure delays and enforcement gaps limit the practical value for investment timing.

The real story here may be transparency itself. As public pressure mounts for stricter rules or outright trading bans, these disclosures serve more as a window into potential conflicts of interest than a reliable investment strategy.
