Members of Congress have up to 45 days to disclose a stock trade, so no tracker can show you one in real time. Every tool in this roundup starts from the same two free government databases.
The real differences are verification, coverage, how clearly the delay is shown, and price. For most readers a free tool that links to the filing is enough; pay only for alerts or an API. Below, we price out a year of each paid option and show you the one column that tells you how stale a trade was.
Watch it play outEvery tracker waits on the same two government databases
A member of Congress makes a stock trade.
The law gives them up to 45 days to disclose it. Each dot is a day nobody can see the trade.
Then the filing lands in one of two free government databases: the House Clerk or the Senate eFD.
Every tool in this roundup starts from those same two databases. None can show a trade in real time.

The short version
Free: the House Clerk and Senate eFD sites, Capitol Trades, and Yield Theory's tracker.
Alerts: Unusual Whales puts politician data in paid tiers from $42–50 a month, with 25 custom alerts on the cheapest.
Watch it play outA year of alerts costs about $504; the source data is free
Unusual Whales' cheapest plan with custom alerts costs $42 a month, billed annually.
Twelve of those months make one bill.
Pour them into one pool: about $504 a year, for 25 custom alerts.
The cheapest API, Quiver's Hobbyist tier, is about $300 a year, with no commercial rights. Areas follow cost.
Every one of these plans reads data the House Clerk and Senate eFD give away free.

API: Quiver Quantitative's starts at $30 a month; Unusual Whales' at $150.
No tool escapes the 45-day filing window or the value ranges that replace share counts.

How to judge a tracker
We scored each tool on six things: source and verification, coverage, lag display, alerts, API, and price.
Two limits apply to every tool. Under the STOCK Act, members may file up to 45 days after a trade, so the public record itself is late. Filings also report value ranges, not share counts, so any "volume" figure is an estimate. Our guide to how to read congressional disclosures covers each field.
Every tracker sits downstream of the same free filings
Member trades to PTR filed (Up to 45 days later)
PTR filed (Up to 45 days later) to House Clerk, Senate eFD (Free official record)
House Clerk, Senate eFD (Free official record) to Trackers (Same filings, repackaged): Ranges, not shares
The official House and Senate sites
The government publishes filings free, in two unconnected systems. The House Clerk's Financial Disclosure Reports page cites Section 8 of the STOCK Act as its authority. It offers a search of individual reports and year-by-year bulk downloads for 2008 through 2026. Periodic Transaction Reports (PTRs, the forms members file for each trade) are PDFs, and some are scanned images rather than machine-readable text.
The Senate's Electronic Financial Disclosure system, or eFD, holds reports for senators, former senators, and Senate candidates filed from 2012 onward. Senator reports stay available for six years after leaving office. Before you search, eFD makes you accept an Ethics in Government Act clause barring use of reports for commercial purposes, credit decisions, or fundraising, with a civil penalty of up to $10,000.

Neither offers alerts, an API, or a merged view, and the Clerk states no posting cadence. They are the verification layer for everything else: if a tracker row can't be traced to a PDF here, treat it as unverified.
Capitol Trades
Capitol Trades is a free site run by 2iQ Research. Its about page describes "an established and proven process combining automated and manual record collection" and says "2iQ's data analysts take great care to ensure that the data we publish is always accurate."
It covers both chambers, but the footer says "the historical data available on our website is restricted to the past 3 years." On September 20, 2026 the trades page showed 37,037 trades from 1,815 filings by 211 politicians in that window.
Spot the red flag
Tap the line you think is the tell.
Spotted it.Not that line.The "filed after" count. It puts the disclosure lag on every row, which makes it the best thing on the page.
Rows show published and traded dates, owner, type, size range, a reference price, and a "filed after" day count. That last column is the best thing on the page: it puts the disclosure lag on every row.
Alerts are a Twitter feed and a weekly newsletter, not per-member or per-ticker. The site returned "page not found" for /pricing and /faq, so no API or paid tier is published. Our Capitol Trades comparison goes deeper.
Quiver Quantitative
Quiver publishes a Congress Trading dashboard covering both chambers. On September 20, 2026 its most-active list mixed House and Senate members, each with a trade count and an "estimated trade volume."
The data "is parsed from congressional disclosures by Quiver Quantitative," but no manual verification step is described and dashboard rows don't link to filings. Marketing copy says users can react to trades "within moments of being filed," but no cadence is published.
Alerts are premium. Website premium pricing isn't public: /pricing redirects to a sign-up form. The API is priced openly on api.quiverquant.com/pricing:

The API page shows a sample Senate trade with ReportDate, TransactionDate, Ticker, Range, House, Party, and derived fields such as ExcessReturn. The return fields are Quiver's calculations, not disclosed facts.
Unusual Whales
Unusual Whales is mainly an options-flow platform. Its politics page, titled "Track Congressional & Senate Stock Trades," shows trade date, filing date, value range, asset type, and filing-status notes, plus top-trader lists and an annual Congressional Trading Report.
The pricing page includes "politician trade information" in all three paid Dashboard & Tools tiers:

A free account gets "limited data" with 15-minute delayed market data, and politician data isn't listed as free. The API is sold separately, without the website: API Basic is $150 a month with a 7-day trial and 40,000 requests per day, and API Advanced is $375 with unlimited requests. Both include "Congressional and Insider Trades." Commercial plans start at $625 a month, billed annually.

No verification method appears on the pages we fetched. Unusual Whales historically supplied disclosure data to the NANC and KRUZ ETFs; the funds' July 2026 SEC filing says that arrangement has ended, as covered in our NANC and KRUZ explainer. See also our Unusual Whales comparison.
Member research: Top-trader lists show who bought what, not whether the business is worth owning at today's price. Our free NVIDIA issue, NVIDIA's growth has a financing bill, shows that second step: working backward from a test price to the revenue and margins it would require.
Yield Theory's tracker
This one is ours. The politician-trades directory and congressional-trades dataset cover both chambers for 2025–2026 filings. A weekday job parses every machine-readable PTR in the Clerk's 2025 and 2026 indexes and publishes a new snapshot only when filings change; a separate job reads electronically filed Senate PTRs from eFD for the same years. As of the September 28, 2026 snapshots:
House: 918 filings by 142 members. 798 PDFs were machine-readable and produced 11,015 normalized rows.
Senate: 238 electronic filings producing 2,321 rows from 34 senators.
Every row keeps the original filing URL, owner code, value range, transaction date, and filing date. Member and ticker pages show median filing lag and flag rows filed after the 45-day deadline. The most-active ranking and ticker index use the same rows. Browsing and CSV or JSON downloads are free.
The trade-offs are deliberate: two filing years, refreshed on weekdays. Image-only House PDFs are left out rather than OCR-guessed, so affected members' totals run low, and the page says so. There are no alerts or API; in exchange, every number traces to a government-hosted PDF and ranges stay ranges.

What a year of each paid option costs
Monthly prices hide the real commitment. Here is the arithmetic on the prices above, multiplying each by 12. We read the "billed annually" figure as a monthly rate paid once a year.

So the cheapest way to get custom alerts is about $504 a year, and the cheapest API is $300 a year without commercial rights. Every one of those plans reads data the Clerk and eFD give away free.

Cost of one year, billed annually where offered. The Hobbyist tier has no commercial rights.
A useful test before paying: divide the annual cost by the number of trades you would realistically act on. Hypothetical example: if $504 of alerts leads you to research 20 trades a year, $504 ÷ 20 = $25.20 per trade before you've bought anything, and each of those trades is already up to 45 days old.
Try it yourself
This takes about 10 minutes and shows you what any tracker is really giving you.
Find the same trade on Capitol Trades and compare its "filed after" count with your own.
By the end you should be able to answer: did any tool tell you something the free filing didn't, and would you have paid to see it sooner?
Our read
Browsing what members trade? Start free. Capitol Trades has three years of history with lag on every row; our tracker has filing-linked rows you can download and audit.
Want alerts? Unusual Whales is the clearest option, with custom alerts on every paid plan. Quiver has them too, but hides the price behind a sign-up.
Need an API? It's Quiver or Unusual Whales. Quiver is cheaper to start, though its $30 tier has no commercial rights.

Questions readers ask
Is there a free congressional stock tracker?
Yes. The House Clerk and Senate eFD sites are free and authoritative but separate. Capitol Trades and Yield Theory's tracker are free and cover both chambers, and both show filing lag on each row.
Can any tracker show congressional trades in real time?
No. Members have up to 45 days to file under the STOCK Act, so every tracker is at least as late as the filing. A faster refresh only shortens the gap between the filing being posted and you seeing it.
Why do trackers show different totals for the same member?
Filings report value ranges, so any dollar total is an estimate built from bands. Coverage windows differ too: Capitol Trades limits history to three years, and our tracker covers 2025–2026 filings and leaves out image-only House PDFs.
Can I use this data for a business?
Be careful. The eFD terms bar using reports for commercial purposes, credit decisions, or fundraising, with a civil penalty of up to $10,000. Quiver's cheapest API tier also carries no commercial rights.
Go deeper with member research
A tracker tells you what a member of Congress bought. It can't tell you whether the business is worth owning. That's the work our member reports do:
Sales up about 18% on the prior quarter, receivables up about 55%, supply commitments at $279 billion. What NVIDIA’s financing bill means for the price you pay.
Yield Theory is independent stock research for people investing their own money. Here is what's free, what members get, and three pieces to read first.
The thesis, the numbers behind it, and what would break it. Full access is $39 a month.
