Best Capitol Trades Alternatives in 2026 (Compared)
Capitol Trades is free, needs no sign-up and makes congressional trades easy to browse. That is why most people start there. But a list of trades only goes so far. Sooner or later you want to know what a politician actually holds, how it performed, and how much of that was visible by the time the trade was disclosed.
The best Capitol Trades alternative: InsiderCat. It turns the same filings into a live portfolio for every politician, adjusts returns for filing delays, and adds corporate insiders, Trump, the Trump administration, alerts and an API.
Quick answer

| 2 | Quiver Quantitative | Best for many unrelated alternative datasets | Paid |
| 3 | Unusual Whales | Best for options traders | Politician data from $50/month |
| 4 | Open Cabinet | Best free tracker for cabinet officials | Free, open source |

What Capitol Trades does well, and where it stops
- Does well: Free, no account, a clean interface, and the reporting gap in days for each trade.
- Stops at: Lists of trades. We did not find returns adjusted for the reporting gap, live portfolios with performance, or an official public API.
If browsing recent trades is all you need, Capitol Trades is fine. If you want to understand what politicians hold and how they performed, you need InsiderCat.
The best Capitol Trades alternatives
1. InsiderCat: best overall
- Portfolios, not just trades: Each politician's live portfolio shows what they hold now and how it has performed.
- Delay-adjusted returns: Capitol Trades shows how late a trade was reported. InsiderCat goes further and recalculates returns as if each trade happened on the reporting date, which shows how much of the performance was visible once the filing became public. See our filing delays guide.
- More than Congress: Corporate insider trades, Trump's portfolio, the U.S. government's portfolio, a defense portfolio and STOCK Act violations.
- Alerts and API: Follow a politician or a stock for email alerts, or use the API & MCP server with your own tools or AI assistant.
- Why it wins: It answers the questions Capitol Trades leaves open: what does this politician hold, how has it done, and what did the public actually get to see?
2. Quiver Quantitative: best for many unrelated datasets
- Congress trading pages alongside a broad set of other datasets, with an official MCP server.
- Where it falls short: Broad rather than deep on politicians, and we did not find delay-adjusted returns. See our Quiver alternatives comparison.
3. Unusual Whales: best for options traders
- Mainly an options flow and dark pool platform. Politician trade data comes with its paid plans, starting at $50/month ($42/month billed annually).
- Where it falls short: You pay for an options platform to get politics data on the side.
4. Open Cabinet: best free cabinet tracker
- Free and open source. Tracks trades by 37 senior executive branch officials from Office of Government Ethics filings, with a late-filing tracker and email alerts.
- Where it falls short: No Congress and no corporate insiders.
5. Disclosed Capitol: best free API
- A congressional trading API. Its free tier covers the last 90 days of trades. Full history is on the Pro plan.
- Where it falls short: Raw trades for developers, not portfolios, and no MCP server listed.
6. The official filings: best for verification
- The House Clerk's disclosure search and the Senate's eFD search are the original source behind every tracker.
- Where they fall short: Mostly PDFs, with no portfolios, returns or alerts.
The verdict
InsiderCat is the best Capitol Trades alternative in 2026. It keeps what makes congressional tracking useful and adds what Capitol Trades leaves out: live portfolios, delay-adjusted returns, Trump and the Trump administration, corporate insiders, alerts and an API.
Pick something else only if:
- you need lobbying, patents or other unrelated datasets (Quiver Quantitative),
- you already pay for an options flow platform (Unusual Whales),
- or you only want cabinet officials, for free (Open Cabinet).
