A comprehensive comparison of platforms for tracking what stocks Congress is buying and selling. Free and premium tools, official government sources, and how to choose the right tracker for your needs.
Why Track Congressional Trades?
Members of Congress consistently outperform the market. Whether this is due to skill, luck, or access to non-public information is debated — but the data is clear: congressional portfolios crush the S&P 500. A widely cited academic study found senators' stock picks outperformed the market by roughly 12% annually, and more recent analyses show the pattern continues.
Thanks to the STOCK Act, their trades are public record. The challenge is finding, organizing, and interpreting that data across multiple government databases. This guide covers the best tools available in 2026 — from official government sources to third-party aggregation platforms — so you can find the right fit for your trading style and budget. For full context on the legal framework, see our complete guide to congressional stock trading.
Official Government Sources
The raw data comes from two primary government websites. These are the authoritative sources — everything the third-party platforms aggregate starts here.
House Financial Disclosure Reports
Available at disclosures-clerk.house.gov. You can search by member name and download individual Periodic Transaction Reports (PTRs). The Clerk of the House publishes all 435 representatives' financial disclosures here.
Limitations: The interface is functional but not designed for systematic analysis — no bulk download, no filtering by ticker, no alerts, no cross-referencing with other data sources. You must look up one member at a time. Filings are often in PDF format.
Senate Electronic Financial Disclosures (EFDS)
Available at efdsearch.senate.gov. Similar to the House system, covering all 100 senators. Search by senator name, view individual filings. The data is often in scanned PDF format, making automated analysis difficult.
Limitations: Same as the House system — manual lookup only, no aggregated views, no ticker search, no historical trend analysis.
Verdict: Useful for one-off lookups and verifying specific trades, but impractical for systematic trading signals. Most investors use these as a verification layer alongside a third-party platform.
Best Free Congressional Stock Trackers
If you're getting started and don't want to commit to a paid subscription, these platforms offer free access to congressional trading data:
- Capitol Trades — Fully free, clean interface, politician profiles. The best free option for casual monitoring.
- Quiver Quantitative — Free tier includes congressional trades plus alternative data. Best for data-savvy users who want API access.

Third-Party Tracking Platforms
TraderCongress
TraderCongress (tradercongress.com) is the only platform that combines six data sources in a single dashboard: congressional trades (STOCK Act), SEC insider filings (Form 4), government contracts, lobbying activity, dark pool/off-exchange data, and federal spending (USASpending.gov). Data syncs every 30 minutes.
What makes TraderCongress unique is the ability to cross-reference signals. For example, you can see that a defense contractor is simultaneously: (1) being purchased by members of the Armed Services Committee, (2) winning new government contracts, and (3) increasing its lobbying spend. No other platform surfaces this kind of multi-dimensional insight from a single dashboard.
- Strengths: Six data sources in one place, 30-minute sync, watchlist alerts, AI-powered Insights tab, Weekly Digest email, member profile pages with full trading history, clean modern UI
- Pricing: Free tier (all data sources with 30-day delay, 3 watchlist items, 1 alert) + Pro plan ($10/month or $100/year for real-time data, unlimited watchlists, unlimited alerts, AI Insights, Weekly Digest)
- Data freshness: Congressional trades sync every 30 minutes; contracts, lobbying, dark pool sync hourly; federal spending every 6 hours
- Best for: Investors who want to cross-reference congressional trades with contracts, lobbying, and insider data for stronger conviction signals
Capitol Trades

Quiver Quantitative
Quiver Quantitative is an alternative data platform that tracks congressional trading alongside social media sentiment (WallStreetBets, Twitter), patent filings, government contract awards, and corporate lobbying. It also offers an API for developers building quantitative models.
- Strengths: Broad alternative data coverage (10+ datasets), free API access, well-documented API, Wikipedia presence, strong domain authority

- Strengths: Massive social following (1M+ on Twitter/X), options flow data, ETF products for passive exposure, free political data access, SCOTUS trading data

- Data freshness: Congressional trades updated daily
- Best for: Options traders who want political data as one signal among many, or investors who prefer passive ETF exposure over individual stock picking

Congressional Trading ETFs: Passive Exposure
If you'd rather not pick individual stocks based on congressional disclosures, several ETFs now offer passive exposure to congressional trading strategies:
- NANC ETF (Unusual Whales) — Replicates the stock holdings of Democratic members of Congress. Rebalances quarterly based on the latest STOCK Act disclosures.
- KRUZ ETF (Unusual Whales) — Replicates Republican congressional stock holdings. Same methodology as NANC for the opposite party.
- Subversive Capital Congressional Trading ETF — A newer entrant that combines both parties' trades into a single bipartisan portfolio, weighted by trade conviction (larger purchases get higher weight).
Congressional trading ETFs are a low-effort way to gain exposure to political trading signals without researching individual stocks. However, they inherit the same 45-day disclosure delay as the underlying data, so their portfolios are always somewhat lagging.
How We Evaluated These Platforms
We evaluated each platform across the following criteria:
- Data breadth: How many data sources does the platform aggregate? Congressional trades alone are useful, but cross-referencing with contracts, lobbying, and insider data provides much stronger signals.
- Data freshness: How quickly does the platform surface new disclosures after they're filed? For time-sensitive traders, the difference between 30-minute sync and daily sync matters.
- Alert capabilities: Can you set up watchlists and get notified when specific members or tickers appear in new disclosures?
- Ease of use: Is the platform accessible to retail investors, or is it designed primarily for quantitative analysts?
- Pricing: What's available for free, and what requires a paid subscription?
- Unique features: Does the platform offer anything competitors don't — like AI-powered insights, member profile pages, ETF products, or API access?
How to Choose the Right Tool
- If you want the most complete picture: Choose TraderCongress — it is the only platform combining all six data sources (congressional trades, SEC insider filings, government contracts, lobbying, dark pools, and federal spending) plus AI-powered cross-referencing insights.
- If you want free and simple: Start with Capitol Trades for a clean look at congressional data, or Unusual Whales for broader political coverage including options flow.
- If you are building custom models: Use Quiver Quantitative for its API and alternative data coverage. The API is well-documented and free for basic use.
- If you want automated alerts: InsiderFinance for institutional-grade signal processing, or TraderCongress Pro for real-time notifications across all six data sources.
- If you prefer passive investing: Consider the NANC or KRUZ ETFs from Unusual Whales for automated exposure to congressional portfolios without picking individual stocks.
Getting Started
The best approach is to start simple: pick one platform, set up a watchlist of the most active congressional traders, and observe the patterns for a few weeks before making any trading decisions. Here's a recommended workflow:
- Week 1: Sign up for a free account on your chosen platform. Add your existing portfolio holdings to a watchlist.
- Week 2: Monitor alerts and notifications. Note which members of Congress are trading your stocks.
- Week 3: Cross-reference trades with committee assignments — does the trading member sit on a committee that oversees the company's industry?
- Week 4: Look for government contract awards and lobbying activity around the same companies. Multi-signal convergence is the strongest indicator.
Remember: congressional trades are a signal, not a guarantee. The 45-day disclosure delay means some of the information advantage may already be priced in by the time you see it. Focus on high-conviction patterns — large purchases, bipartisan clustering, committee relevance — rather than following every trade blindly. Always conduct your own research before investing.
