Its own disclaimer names the sources: the Senate's electronic financial disclosure system and the Clerk of the House, with the ProPublica Congress API used to cross-check member details. On 14 September 2026 the trades listing reported 37,219 trades from 1,806 filings, 2.274 billion dollars of volume, 211 politicians and 3,058 issuers — all of it inside a rolling three-year window. Each row carries the traded date, the published date, a "filed after N days" counter, the owner (undisclosed, spouse or joint), the disclosed size band and a price. Fifteen filters sit above it: politician and issuer search boxes, plus committee, party, congress chamber, politician state, asset type, transaction type, trade size, market cap, issuer state, transaction label, gender, sector and issuer country. The other two entry points are an issuer list — 3,058 traded securities ranked by volume, trades and number of politicians, filterable by market cap, sector, state and country — and a politician list with per-member bios, committees and trading history. ## Pricing Free, with nothing to buy. There is no account, no login, no paid tier, no trial and no donation ask, and the site says making it free is the point. The business it feeds is upstream. 2iQ Research sells insider-transaction data on more than 60,000 stocks to hedge funds and quantitative managers through a feed, an API and a scoring model, and publishes no prices for any of it. Capitol Trades is the demonstration, which is worth knowing before treating its roadmap as a commitment to anybody. ## Data & coverage US federal legislators only — House and Senate, no state legislatures, no executive branch, no federal judges. Every ticker in the listing is a US line. The asset-type filter carries 22 values, well beyond equities: stock, non-public stock, preferred shares, ETF, ETN, mutual fund, stock options, futures, crypto, corporate bond, municipal security, REIT, variable annuity, private equity and venture capital funds, ownership interests and several "other" buckets. That breadth is not decoration — the single most-traded issuer on the site is US Treasury bills, at 323 million dollars of disclosed volume across 504 trades on that same date, ahead of Microsoft. Prices are context rather than product. An issuer page shows a last price with 1D, 7D, 30D, 6M, 1Y and YTD changes; Amazon read 256.78 unchanged across five minutes of a Monday session, so treat it as a daily figure and not a quote. ## Integrations None. No API, no export, no webhooks, no spreadsheet add-in, no MCP server. Pushed data amounts to a weekly newsletter and an X account that posts trades as they publish. ## Limitations - The lag is statutory and cannot be engineered away. A member files within 30 days of notification and no later than 45 days after the trade, so a "congressional trade" is history by the time it is public. Late filings are worse and the site shows exactly how bad — that 466-day reporting gap. - Three years of history, rolling. A window that short rules out most of what a researcher would want the data for. - No amounts, only bands, the smallest of which is 1K–15K. Every dollar total on the site, including the headline volume, is an inference from ranges. Anything at or below $1,000 is not reportable at all: the statute covers securities transactions that *exceed* $1,000 (5 U.S.C. § 13104(a)(5)), so the floor of the data is a legal threshold, not a display choice. - Nothing machine-readable. Reading is free; getting the data out is not offered at any price. - The site is marketing for a paid institutional feed. That does not make the numbers wrong, but a free product with no customers has no obligations to them either. ## Alternatives [Quiver Quantitative](https://stockmarketstack.com/tools/quiver-quantitative) is the closest thing in shape — the same disclosure data, but over a REST API and with the history and the export Capitol Trades does not offer. [Unusual Whales](https://stockmarketstack.com/tools/unusual-whales) carries congressional and insider disclosures alongside the options tape, for a reader already paying for flow. [Finnhub](https://stockmarketstack.com/tools/finnhub) and [Financial Modeling Prep](https://stockmarketstack.com/tools/financial-modeling-prep) both expose congressional trading as one endpoint among many. For the filings themselves, the House and Senate disclosure systems are free and authoritative and offer no filtering at all. The rest of the category is at [insider, 13F and congressional trade trackers](https://stockmarketstack.com/categories/insider-13f-trackers). ## FAQ ### Is Capitol Trades free, and do I need an account? It is free and there is no account. There is no sign-up, no login link anywhere in the navigation, no paid tier and no trial. The revenue is elsewhere — 2iQ Research sells insider-transaction data to institutions, and this site is the shop window for it. ### Does Capitol Trades have an API? No. There is no API, no CSV or Excel download and no bulk file. The only download link on the site is a press kit. Anything programmatic has to come from the underlying House and Senate filings, or from a data vendor that resells them. ### How current is the data? As current as the filings, which is not very. Under the STOCK Act a member files within 30 days of being notified of a transaction and in no case later than 45 days after it, so a trade is routinely three to six weeks old the first time anybody outside the filer can see it. Late filings run far longer — one row published on 14 September 2026 covered a trade made on 3 June 2025 and filed 466 days after it, a gap the site prints on every row. ### How far back does the history go? Three years, on a rolling basis. Every page carries the footnote that historical data on the site is restricted to the past three years, so anything older has to be pulled from the House and Senate disclosure systems directly. ### Does it show how much a politician actually traded? No, and neither does the filing. Amounts are disclosed in bands, and the site prints the band — 1K–15K, 15K–50K, 250K–500K and so on. Any dollar volume built from those figures is an estimate stacked on ranges, including the site's own. ## Also from 2iQ Research - [2iQ Insider Transactions Data](https://stockmarketstack.com/tools/2iq-insider-data.md) ## Also worth comparing - [Quiver Quantitative](https://stockmarketstack.com/tools/quiver-quantitative.md) — US political and SEC disclosure data — congress, insiders, lobbying — over one REST API. - [13F.info](https://stockmarketstack.com/tools/13f-info.md) — Every 13F since 2014, free and account-free, from a Rails app you can run yourself. - [OpenInsider](https://stockmarketstack.com/tools/openinsider.md) — Every SEC Form 4, minutes behind EDGAR, through a 40-field screener and no account. - [ChartExchange](https://stockmarketstack.com/tools/chartexchange.md) — The official short interest, IBKR's borrow fee and SEC fails, sold feature by feature. - [Dataroma](https://stockmarketstack.com/tools/dataroma.md) — 83 value investors' 13F portfolios, twenty years of history, free and without an account. - [Fintel](https://stockmarketstack.com/tools/fintel.md) — Ownership, insider and short-interest filings across thirty markets, none of it free.
