Quantgress by the Numbers

Congress trades stocks. Corporate insiders trade stocks. Hedge funds and asset managers file what they hold every quarter. Lobbyists disclose who's paying them and how much. None of this is secret — it's all public record, scattered across a dozen government websites in a dozen different formats. Quantgress pulls all of it into one place and puts it behind a single free API.

Here's what's actually in there: 9.3 million rows, 13 datasets, 25 years of history. From SEC insider filings starting in 2001 to this week's SEC 13F institutional holdings, 14 of those datasets are queryable today with nothing but a free API key.

Congress is trading. We're watching.

27,593 congressional stock trades tracked since 2012, covering 215 sitting and former members of Congress. Split by chamber, that's 11,035 House trades from 135 members and 16,558 Senate trades from 80 senators — filed under the STOCK Act, scraped straight from the House and Senate's own disclosure sites, not a press aggregator.

Corporate insiders leave a paper trail too

78,261 SEC Form 4 insider trades, 2006 through today, across 4,298 companies and 25,656 individual filers — officers, directors, and 10%+ owners moving 26.3 billion shares between them. If a CEO bought or sold their own company's stock in the last 20 years, there's a decent chance it's in here.

The big money: 13F institutional holdings

3.8 million holding records from 8,758 institutional managers — every fund required to file a 13F, going back to 2008 — plus 2.5 million quarter-over-quarter position changes, so you can see what Vanguard, BlackRock, and everyone else added or trimmed last quarter without reading a single PDF.

Follow the lobbying money

55,728 federal lobbying filings from 5,338 registrants. In 2026 alone, filers disclosed $1.6B in lobbying income and $1.9B in lobbying expenses — a live, queryable ledger of who's paying Washington to listen.

Who's getting the government's business

20,260 federal contract awards worth $98.9B combined, spanning 3,851 companies and 50 federal agencies, dating back to 2001. Cross-reference this against the lobbying and donation data and patterns start to show up fast.

Political money, kept legal

116,743 FEC-disclosed corporate and PAC donations totaling $207M+, from 3,446 distinct corporate contributors to 1,543 committees. Because federal law restricts commercial use of raw contributor data, the API also ships an aggregate view — 24 publicly-traded companies' donation totals with no names attached, the same shape industry leader Quiver Quantitative uses for its own paid product.

What executives actually get paid

6,303 Pay-vs-Performance records across 1,779 public companies (FY2022–2025), straight from each company's own SEC XBRL filings. Average tracked CEO total compensation: $13.2 million.

Senators' own disclosed wealth

6,959 individually disclosed assets from senators' Annual Financial Disclosure reports, plus 204 disclosed liabilities — the numbers senators report about their own net worth, not just their trades.

Innovation, tracked

2,428 patent applications and grants across 1,554 assignee companies since 2024, straight from USPTO's open data.

Even the President's trades

413 presidential stock trades from Donald Trump's OGE 278-T disclosures, 236 cleaned and normalized — sourced directly from the OGE/ProPublica filing mirror, not a news summary.

Built for completeness, not just headlines

Behind every summary number is real per-filing work: 941 House disclosure filings and 2,412 Senate disclosure filings individually parsed line-by-line, not estimated from a sample.
