Best Congress Stock Trackers in 2026: Data-Backed Comparison

All 7 trackers show you the same 189,595 STOCK Act filings. Only one scores them with a 7-layer AI engine. We tested 7 platforms that track congressional stock trades and compared data depth, signal scoring, prediction engines, API access, and price. See the disclosure gap pillar (44.9-day average) to understand why timing — not raw data — is the problem worth solving. Here's what we found.

How We Compared

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

#1
GovGreed
Best for: Intelligence-driven trading
Trades: 189,595
Politicians: 343
Data Sources: 8 APIs
Price: Free tier + $24.50/mo Founders

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
#2
Capitol Trades
Best for: Casual browsing
Price: Free
Data Source: STOCK Act filings

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

#3
Unusual Whales
Best for: Options traders who also want congress data
Price: $30–60/month
Data Sources: STOCK Act + options flow + dark pools
Products: NANC & KRUZ ETFs

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

#4
QuiverQuant
Best for: Developers and quantitative analysts
Price: ~$10/month
Data Sources: STOCK Act + lobbying + insider trades
Focus: API-first data access

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

#5
TraderCongress
Best for: Comprehensive research across data types
Price: Subscription
Data Sources: 6 integrated sources

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
#6
Autopilot
Best for: Passive copy-trading
Price: $100/year per folio
Users: 100,000+
Model: Copy-trading via linked brokerage

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

#7
InsiderFinance
Best for: Mobile-first trade alerts
Price: Subscription
Platform: iOS app + web
Data: Congress + insider trades

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.

Frequently Asked Questions

What is the best free congress stock tracker?
Capitol Trades and GovGreed both offer free access to congressional trade data. Capitol Trades is entirely free with a clean interface for browsing raw STOCK Act filings. GovGreed's free tier provides trade data plus politician profiles, with signal scoring and ML predictions available in the Founders tier at $24.50/month. For free raw data, Capitol Trades is excellent. For free data with a path to intelligence layers, GovGreed is the better starting point.
Can you track congress stock trades for free?
Yes. All congressional stock trades are public record under the STOCK Act of 2012. Several platforms provide free access: Capitol Trades offers entirely free browsing, GovGreed has a free tier covering 189,595 historical trades back to 2012, and QuiverQuant provides free API access to raw data. You can also access filings directly from the Senate and House disclosure offices, though the raw PDFs are difficult to search and analyze without a dedicated tool.
Which congress tracker has the best data?
For raw trade data volume, GovGreed leads with 189,595 trades from 343 politicians spanning 2012 to 2026, sourced from both QuiverQuant and Financial Modeling Prep APIs. For data enrichment, GovGreed is the only platform offering 7-layer signal scoring, 256,112 bill-trade correlations, herd detection, and 819 active ML predictions. QuiverQuant offers strong raw data via API. Capitol Trades provides clean presentation of official filings. All major trackers pull from the same public STOCK Act source.
What is the best app to track congress trades?
For a dedicated mobile app, InsiderFinance offers real-time congress trade alerts on iOS. Autopilot provides a mobile-first copy-trading experience. Unusual Whales has a full iOS app that includes congressional trading alongside broader market data. Most other congress trackers, including GovGreed, Capitol Trades, and QuiverQuant, are web-based and work in mobile browsers but do not have native apps yet.
How do congress stock trackers get their data?
Congressional stock trackers pull data from public STOCK Act filings submitted to the Senate Office of Public Records and the House Clerk's office. Most platforms use automated scrapers and third-party APIs (such as QuiverQuant, Financial Modeling Prep, and the Congress.gov API) to collect, normalize, and present the data. The underlying filing data is the same public record — the difference between platforms is how they process, enrich, and present it. GovGreed adds 7 intelligence layers on top of the base filings.
Is it worth paying for a congress stock tracker?
It depends on what you need. Free trackers like Capitol Trades show you the raw filings — who traded what and when. Paid platforms add intelligence: GovGreed's Founders tier ($24.50/month) includes 7-layer signal scoring, ML predictions, an AI chatbot, and API access. Unusual Whales ($30–60/month) adds options flow and dark pool data alongside congress tracking. If you just want to browse filings, free tools work well. If you want scored signals, predictions, or copy-trading automation, a paid tool provides value beyond what free data offers.
What is the most accurate congress stock tracker?
All major congress trackers pull from the same public STOCK Act filings, so raw trade data accuracy is comparable across platforms. Where accuracy differs is in analysis and signals. GovGreed's A+ tier signals have a backtested 72.7% win rate with +10.7% average 30-day returns based on historical data from 2012 to 2026. No other platform publishes validated accuracy metrics for congressional trading signals. For raw filing accuracy, Capitol Trades and QuiverQuant are also reliable sources.
Can you copy congress trades automatically?
Yes. Autopilot is the primary platform for automatic copy-trading of congressional portfolios, with over 100,000 users and pre-built folios mirroring politicians like Nancy Pelosi (15,811 copiers). However, there's an important caveat: STOCK Act filings have a legal reporting deadline of 45 days, and the average actual disclosure gap is 44.9 days. You are copying trades that are already weeks old. GovGreed takes a different approach with ML predictions that anticipate trades before they are filed, rather than copying after disclosure.
