We evaluated each platform across 6 criteria: data sources (where they pull STOCK Act filings), signal scoring (whether they add intelligence beyond raw data), predictions (forward-looking trade forecasts), API access (programmatic data retrieval), price, and unique strengths. All data is from public product pages, documentation, and direct testing as of April 2026. GovGreed is our product — we disclose this and aim to be fair in our comparisons.

In-Depth Reviews What each tracker does well, where it falls short, and who it's for
GovGreed is the only congress stock tracker that goes beyond raw STOCK Act filings to score and predict trades. Its 7-layer signal engine evaluates every qualifying trade across politician quality, herd convergence, bill-trade timing, technical context, sector momentum, campaign contributions, and lobbying alignment, outputting a composite 0–100 score with tier classifications from S to F.
The platform covers 189,595 trades from 343 politicians spanning 2012 to 2026. Beyond scoring, it runs 4 prediction engines (committee markup, pattern analysis, signal bridge, bill correlation) that maintain 819 active predictions covering 76 politicians. A+ tier signals carry a backtested 72.7% win rate with +10.7% average 30-day returns. An AI chatbot allows natural language queries across all intelligence layers.
The free tier includes trade data, politician profiles, and basic browsing. Signal scores, predictions, the AI chatbot, and full REST API access require the Founders tier at $24.50/month. Disclosure: GovGreed is our product.
Strengths
- 7-layer signal scoring (no competitor has this)
- 819 ML predictions from 4 independent engines
- 256,112 bill-trade correlations
- AI chatbot for natural language queries
- Full REST API included in Institutional tier
- Free tier available, no credit card required
Limitations
- No mobile app (responsive web only)
- No options flow or dark pool data
- Signal scoring limited to trades above $50K
- Newer platform, smaller community
Capitol Trades is the most popular free congress stock tracker, and for good reason. The interface is clean, fast, and well-designed. It presents raw STOCK Act filings in an accessible format with sorting, filtering, and politician profiles. For anyone who simply wants to browse what members of Congress are trading, Capitol Trades is the easiest entry point.
The limitation is depth. Capitol Trades shows you the data but doesn't score it, correlate it with legislation, detect multi-politician convergence, or generate predictions. It's a transparency tool, not an intelligence tool. For many users, that's exactly what they need — and the price (free) can't be beat.
Strengths
- Completely free, no account required
- Clean, fast, well-designed interface
- Good politician profile pages
- Strong brand recognition and media citations
Limitations
- No signal scoring or intelligence layers
- No predictions or trend analysis
- No API for programmatic access
- No bill-trade correlation or lobbying data

Unusual Whales is a broad market intelligence platform where congressional trading is one feature among many. Its core strength is options flow scanning, dark pool tracking, and social sentiment data. The platform also launched the NANC and KRUZ ETFs, which mirror Democratic and Republican congressional portfolios respectively.
For congressional trading specifically, Unusual Whales presents raw filings with some filtering and visualization. It does not offer multi-layer signal scoring, bill-trade correlations, herd detection, or ML predictions on congressional trades. Their annual Congressional Trading Report is well-researched and widely cited by media. With 3M+ followers on Twitter/X and a dedicated iOS app, Unusual Whales has the largest community reach of any congress tracker.
Strengths
- Options flow + dark pool + congress in one platform
- NANC/KRUZ ETFs for passive exposure
- iOS mobile app
- Largest community (3M+ followers)
- Well-researched annual reports
Limitations
- No signal scoring on congressional trades
- No ML predictions or bill correlations
- Higher price ($30–60/mo) for congress-focused use
- Congressional data is a side feature, not the focus

QuiverQuant is the API-first option. If you're a developer or quantitative researcher who wants raw congressional trading data piped into your own models, QuiverQuant is the most programmatic-friendly choice at a low price point. The platform aggregates STOCK Act filings, lobbying disclosures, insider transactions, and government contract data into clean, well-documented API endpoints.
The tradeoff is that QuiverQuant provides data, not intelligence. There's no signal scoring, no trade predictions, no bill-trade correlations, and limited visualization compared to tools like GovGreed or Capitol Trades. It's built for people who want to run their own analysis, not for those seeking ready-made insights.
Strengths
- Clean, well-documented REST API
- Low price point (~$10/month)
- Multiple data types (lobbying, insider, contracts)
- Developer-friendly, good for custom models
Limitations
- No signal scoring or intelligence layers
- No predictions or herd detection
- Limited visualization and UI
- Requires technical skill to use effectively

TraderCongress aggregates data from 6 sources including STOCK Act filings, lobbying disclosures, committee assignments, campaign contributions, and voting records. The platform aims to be a one-stop research hub for anyone investigating the intersection of politics and markets.
As a newer entrant in the space, TraderCongress is still building out its feature set. The breadth of data sources is a genuine advantage — few other platforms combine lobbying, contributions, and trades in a single interface. The platform does not yet offer the automated signal scoring or ML predictions available in GovGreed, but its research-oriented approach appeals to journalists, academics, and thorough retail investors who prefer to draw their own conclusions from comprehensive data.
Strengths
- 6 integrated data sources in one platform
- Lobbying + contributions alongside trades
- Research-oriented interface
Limitations
- Newer platform, still building features
- No signal scoring or ML predictions
- No API access
- Smaller user community
Autopilot takes a fundamentally different approach: instead of showing you data and letting you decide, it automatically mirrors politician portfolios in your brokerage account. Pre-built "folios" track politicians like Nancy Pelosi, and trades are executed automatically when new disclosures appear. The Pelosi tracker alone has 15,811 copiers.
The core limitation is the disclosure delay problem. STOCK Act filings have a legal reporting deadline of 45 days, and the average actual disclosure gap is 44.9 days (based on GovGreed's analysis of 189,595 filings). By the time Autopilot copies a trade, the market has often already moved. There's no intelligence layer to filter which trades are worth copying — it mirrors everything, including small trades and routine portfolio rebalancing.
Strengths
- Fully automated copy-trading
- Large user base (100K+ users)
- Simple setup, connects to brokerage
- Affordable at $100/year per folio
Limitations
- 45-day average disclosure delay
- No signal filtering — copies all trades
- No intelligence or scoring layer
- Blind copy-trading ignores trade context

InsiderFinance combines congressional stock trade tracking with SEC insider trading data, delivered primarily through real-time push alerts on its iOS app. For mobile-first traders who want notifications the moment a new congressional filing drops, InsiderFinance offers the best alert experience.
The platform focuses on speed of notification rather than depth of analysis. It does not offer multi-layer signal scoring, bill-trade correlations, or ML predictions. The alert-first approach serves traders who prefer to do their own research after receiving a timely notification, rather than relying on a platform to score and rank trades for them.
Strengths
- Real-time push alerts on iOS
- Combines congress + SEC insider trades
- Fast notification on new filings
- Mobile-first experience
Limitations
- No signal scoring or intelligence layers
- No predictions or bill correlations
- No API access
- Alert-focused, limited analysis tools
What Makes a Good Congress Stock Tracker? The criteria that separate data viewers from intelligence platforms
Data Completeness
How far back does the data go? How many politicians and trades are covered? The best trackers include data from 2012 (when the STOCK Act passed) to present, covering both chambers. GovGreed tracks 189,595 trades from 343 politicians.
Intelligence Layer
Raw filings tell you what happened. Intelligence layers tell you what it means. Signal scoring, bill-trade correlations, and herd detection transform raw disclosure data into actionable signals with measurable historical accuracy.
Forward-Looking Analysis
The most valuable tracker doesn't just show past trades — it predicts future ones. ML-powered prediction engines can forecast who will trade what based on committee activity, historical patterns, and signal convergence.
Data Source Transparency
Trustworthy trackers cite their sources: STOCK Act filings, Congress.gov API, FEC Open Data, SEC EDGAR, Senate LDA. Platforms that don't disclose data provenance should raise immediate red flags.
API and Export Options
Serious researchers and quantitative traders need programmatic access. A good tracker offers a REST API or data export functionality, not just a web dashboard locked behind a subscription.
Fair Pricing
Congressional trade data is public record. Platforms that charge $50+/month for basic filing access are overcharging. Look for free tiers for raw data and reasonable pricing ($10–30/month) for intelligence features.
Honorable Mention: Pelosi Tracker
Worth mentioning separately: Pelosi Tracker is a single-politician tracking tool focused exclusively on Nancy Pelosi's trades. With 15,811 copiers, it's the most popular individual politician tracker. If you only want to follow one politician, it's a simple, focused tool. However, it doesn't extend to the other 342 trading members of Congress, and offers no intelligence layer or scoring.
For a broader view of who to follow — and why — multi-politician platforms like GovGreed, Capitol Trades, or Unusual Whales are more complete.
