Best Quiver Quantitative Alternatives in 2026 (Compared)
Quiver Quantitative bundles many datasets: Congress, lobbying, government contracts, patents, Reddit activity and more. Most people come for one thing: what politicians and insiders are trading. If that is you, you are paying for a bundle you do not use, and getting less depth where it matters.
The best Quiver alternative: InsiderCat. It goes deeper on politicians' portfolios, adjusts returns for filing delays, and covers Trump, the Trump administration, the stocks Trump mentions and his sponsors, which Quiver does not package.
InsiderCat vs Quiver Quantitative
| InsiderCat | Quiver Quantitative | |
|---|---|---|
| Congressional trades | Yes | Yes |
| Live portfolio per politician | Yes, with holdings and performance charts | Portfolio leaderboard and holdings data |
| Returns adjusted for filing delays | Yes, calculated from the reporting date | Not that we found; returns are measured from the transaction date |
| Trump's trades | Live portfolio compared with the S&P 500 | Trade tracker |
| Trump administration, Trump mentions and Trump sponsors portfolios | Yes | We did not find an equivalent |
| Corporate insider trades | Yes | Yes |
| Email alerts for politicians and stocks you follow | Yes | Paid plans |
| API and MCP server | Yes | Yes |
| Price | Paid (see pricing) | Paid |
The verdict: For tracking what politicians, insiders and the Trump administration hold, InsiderCat wins on every row that matters. Quiver only comes out ahead if you need its unrelated datasets.
Why people switch from Quiver to InsiderCat
- They want portfolios, not just trades. InsiderCat rebuilds each politician's live portfolio: what they hold today and how it has performed.
- They care about the filing delay. Members of Congress can report up to 45 days after a trade. InsiderCat shows each portfolio's return as if every trade happened on the reporting date, so you see how much of the performance was visible once the filing was public. Our filing delays guide explains how to read it.
- They want the full Trump picture. Besides Trump's own portfolio, InsiderCat tracks the U.S. government's portfolio, stocks Trump mentions and companies that sponsor his projects.
Other Quiver alternatives
2. Capitol Trades: best free option
- Free, no sign-up. A clean way to browse recent congressional trades, with the reporting gap shown for each trade.
- Where it falls short: We did not find portfolio returns adjusted for that gap, or an official public API.
3. Unusual Whales: best for options traders
- An options flow platform that includes politician trade data from Retail Basic at $50/month ($42/month billed annually). Has its own API and MCP server, sold separately.
- Where it falls short: You pay for an options platform to get politics data on the side.
4. Open Cabinet: best free cabinet tracker
- A free, open-source tracker of stock trades by 37 senior executive branch officials, from Office of Government Ethics filings.
- Where it falls short: No Congress and no corporate insiders.
5. The official filings: best for verification
- The House Clerk's disclosure search and the Senate's eFD search are free and are the original source for every tool here.
- Where they fall short: Mostly PDFs, with no portfolios, returns or alerts.
The verdict
InsiderCat is the best Quiver Quantitative alternative for anyone who comes to Quiver for political and insider trading data. You get deeper politician portfolios, delay-adjusted returns and the most complete Trump coverage, without paying for datasets you do not use.
