Best Congressional Trading Trackers in 2026 (Compared)
Every congressional trade comes from the same public filings. The trackers differ in what they do with them: most stop at a list of trades. The best ones show you what politicians actually hold and how much of their performance you could have seen once the trade was disclosed.
Our pick: InsiderCat. It brings together what the other trackers split up: a live portfolio for every politician, returns adjusted for filing delays, and coverage of corporate insiders, Trump and the Trump administration in one place.

What makes a great congressional trading tracker
- Portfolios, not just trades: A list of trades tells you what was filed. A portfolio tells you what a politician holds now and how it has performed.
- Handles the filing delay: Members of Congress can report a trade up to 45 days after it happens. A great tracker shows how much that delay changes the picture.
- Links to the source: You should be able to open the original filing behind every trade.
- Covers more than Congress: Corporate insiders, Trump and the executive branch file in different places. The best tool brings them together.
- API access: For spreadsheets, scripts and AI assistants.

The best congressional trading trackers
1. InsiderCat: best overall
- Live portfolios: Rebuilds each politician's live portfolio from their filings, with holdings and performance charts.
- Delay-adjusted returns: Every portfolio also shows returns calculated as if each trade happened on the reporting date instead of the trading date. That separates what a politician earned from what was visible once the filing became public. Our guide to filing delays shows how to use it.
- Everything in one place: Corporate insider trades, Trump's portfolio, the Trump administration's portfolio, a defense portfolio and STOCK Act violations.
- Alerts and API: Follow a politician or a stock to get email alerts, or connect the data to your own tools and AI assistant through the API & MCP server.
- Why it wins: The others show you trades. InsiderCat shows you the portfolio behind them, how it performed, and how much of that was visible to the public.
2. Capitol Trades: best free option
- A clean, free website for browsing congressional trades by politician, company or date. No sign-up.
- Where it falls short: It shows how many days each trade was reported late, but we did not find returns adjusted for that delay. We also could not find an official public API, so the data stays on the website.
3. Quiver Quantitative: best for many unrelated datasets
- Congress trading pages alongside a large set of other datasets, such as lobbying, government contracts and Trump's trades.
- Where it falls short: Its breadth comes at the cost of depth on politicians. Its returns measure each trade from the transaction date, not delay-adjusted portfolio returns.
4. Unusual Whales: best for options traders
- Mainly an options flow and dark pool platform. Politician trade data is included in its paid plans, starting with Retail Basic at $50/month ($42/month billed annually).
- Where it falls short: You pay for an options platform to get politics data on the side.
5. Official House and Senate sites: best for checking a filing
- The House Clerk's disclosure search and the Senate's eFD search are where every tracker gets its data. Free.
- Where they fall short: Filings are mostly PDFs, with no portfolios, returns or alerts. In our filing delays guide, a news story reported a purchase that the filing showed was a sale. That is why a tracker that links back to the source matters.
The verdict
InsiderCat is the best congressional trading tracker in 2026. It shows what politicians hold, how they performed, and how that performance looks once filing delays are taken into account, with Trump, the Trump administration and corporate insiders in the same place.
Pick something else only if:
- you just want a free look at recent trades (Capitol Trades),
- you need lobbying, patents or other unrelated datasets (Quiver Quantitative),
- or you already pay for an options flow platform (Unusual Whales).
