The 5 Best Congressional Stock Trackers in 2026 (Ranked)

The market for congressional stock trackers has grown significantly since the STOCK Act became a retail investing topic. In 2026, there are at least a dozen tools claiming to surface congressional trading data.

Most of them are doing the same thing: pulling from the same public filings and displaying a table. A few are doing something more interesting.

Here's an honest ranking of the five worth knowing about.

What We Evaluated

Each tool was assessed on:

• Data freshness: How quickly new disclosures appear after official filing
• AI / enrichment: Does it tell you why a trade matters, or just that it happened
• Filtering and search: Can you quickly find what you're looking for
• Alerts: Email or push notifications for watchlist items
• Price: Value relative to what you actually get
• Design: Is it usable or just a data dump

1. Cloakroom — Best Overall

Best for: Investors who want the why, not just the what

Cloakroom is the only tracker built specifically around AI interpretation of congressional trades. Every disclosure gets:

• An AI Intent Score (0–100) based on committee overlap, legislation timing, and disclosure lag
• A plain-English reason explaining what's driving the score
• Cluster detection when 3+ members trade the same ticker in 7 days
• Velocity spike badges when a member's trading pace doubles
• Insider correlation cross-referencing congressional buys with SEC Form 4 filings

The free tier is genuinely useful (10 trades, intent score numbers, leaderboard). The real value is in the Starter plan ($9/mo) where AI reasons unlock.

Weaknesses: No options flow data. CSV export is limited on lower tiers.

Verdict: The best tool if congressional trading is your primary focus.

2. Quiver Quant — Best for Quants

Best for: Data analysts and quant traders who want raw access

Quiver Quant aggregates a wide range of alternative data — congressional trades, lobbying disclosures, government contracts, SEC filings — in a single platform. The congressional layer is solid but not the star of the show.

Where it excels:

• API access for programmatic consumption
• Data export for building your own models
• Wide alternative data coverage beyond just STOCK Act

Where it falls short:

• No AI enrichment on individual trades
• UI is functional but not polished
• Congressional data is one feature among many, not the focus

Pricing: ~$25/mo for the full dataset access.

Verdict: Best if you're building something, not just browsing.

3. Unusual Whales — Best for Options Traders

Best for: Options traders who want congressional context alongside market flow

Unusual Whales started as an unusual options activity tracker and added congressional data as a complementary signal. The combination is genuinely useful if options flow is your primary lens.

Where it excels:

• Deep options flow data (dark pool prints, unusual activity)
• Congressional data is contextualised alongside market microstructure
• Active social community and real-time commentary

Where it falls short:

• Congressional data is a secondary feature, not the core product
• No AI interpretation of individual trades
• Expensive if you only want the congressional layer

Pricing: ~$25/mo.

Verdict: Worth it if you already care about options flow. Not ideal as a standalone congressional tracker.

4. Capitol Trades — Best Free Option

Best for: Casual users who want basic data at no cost

Capitol Trades (capitoltrades.com) is the cleanest free-tier option. It displays STOCK Act disclosures in a readable format, lets you search by member or ticker, and has reasonable filtering.

Where it excels:

• Genuinely free for basic use
• Clean, readable interface
• Good member profile pages with full disclosure history

Where it falls short:

• No AI enrichment whatsoever
• No alerts or watchlist
• No sector analysis, clustering, or pattern detection
• Data depth is limited

Pricing: Free.

Verdict: Good starting point. You'll outgrow it quickly.

5. Senate Stock Watcher — Best for Senate-Focused Research

Best for: Tracking Senate-specific activity and legislative connections

Senate Stock Watcher is a community-maintained project (senatestockwatcher.com) that focuses specifically on Senate disclosures with good data hygiene. It's not a commercial product but it's more reliable than many free alternatives.

Where it excels:

• Accurate, well-maintained Senate data
• Good historical record
• Open source, which means community verification

Where it falls short:

• Senate only (no House)
• No AI features, alerts, or analysis
• Minimal UX investment

Pricing: Free.

Verdict: Useful as a data source for researchers. Not a replacement for a real product.

Our Recommendation

If you're new to congressional stock tracking, start with Capitol Trades or the Cloakroom free tier. The data is the same — what you're evaluating is whether the AI interpretation layer changes how you use it.

In our experience, once you see a trade explained as "Senate Intelligence Committee member + 40-day disclosure lag + defence sector cluster activity = Intent Score 88," you can't go back to looking at raw tables.
