# Coldpine

> Coldpine is the intelligence layer on Congressional stock trading. It parses every U.S. House and Senate financial disclosure (STOCK Act filings), scores each trade by signal strength, detects when multiple members buy the same stock, and ranks members by their real return versus the S&P 500. It answers the question free trade feeds do not: not just what Congress traded, but which trades matter and which members actually beat the market.

Coldpine is a publisher of intelligence on public Congressional disclosures. It is informational only, not investment advice, and it does not connect to anyone's brokerage or execute trades. Data is sourced from the official U.S. House Clerk and Senate eFD disclosure portals.

Key facts:
- Covers both chambers (House and Senate), parsed and scored within hours of disclosure.
- Assigns a signal score (0 to 1) to each trade from four factors: disclosure speed, trade size, cluster activity (multiple members buying the same name), and the member's track record.
- Measures each member's 90-day alpha versus the S&P 500 on disclosed purchases. Most members do not beat the market; Coldpine surfaces the few who do.
- Pricing: free during early access. Every account includes the full database plus the intelligence layer (AI trade narratives, real-time alerts, watchlists, and backtesting), no card required. Paid Pro plans return after early access.
- Operated by Coldpine LLC, a California company. Website: https://coldpine.io

## Research
- [Can Members of Congress Trade Stocks? The Rules](https://coldpine.io/research/can-members-of-congress-trade-stocks) (October 19, 2026): Yes. Members of Congress, their spouses and dependent children can buy and sell individual stocks if they report each trade within 45 days. What the rules require, how the reports work, where the 2026 proposal to stop members buying stocks stands after the House and Senate votes, and how promptly trades are reported. Reporting figures computed live.
- [Do Members of Congress Trade Crypto?](https://coldpine.io/research/does-congress-trade-crypto) (October 19, 2026): A few do, and it is a small share of what they report. Every crypto-linked transaction members of Congress have disclosed since 2023, in three groups: coins held directly, spot bitcoin and ether funds, and crypto-company stocks. Member by member, with who reported the most, the largest reported amounts, bitcoin and ether counted separately, and the split by party. Computed live.
- [Which States' Members of Congress Trade the Most Stocks?](https://coldpine.io/research/congress-stock-trades-by-state) (October 16, 2026): California, by transaction count, and most of that is one member. Every securities transaction on the reports filed this year, grouped by the state the member represents, with the members behind each state's count, the largest filer's share, the ranking with each state's largest filer set aside, and the states with no reported trade. Computed live.
- [How Many Members of Congress Trade Stocks?](https://coldpine.io/research/how-many-members-of-congress-trade-stocks) (October 13, 2026): About one in four, going by the reports they file. Every member of the House and Senate with a securities transaction on a periodic transaction report this year, counted per person and set against the 535 voting seats, with how many reported a ticker-listed stock or fund, how many reported only family-account trades, and the House count for each year since 2023. Computed live.
- [Is Congress Buying or Selling Stocks?](https://coldpine.io/research/is-congress-buying-or-selling-stocks) (October 10, 2026): Members of Congress disclose more purchases than sales, about three for every two. Most of that gap is one filer: without the largest, the split is close to even, and member by member about as many sell more than they buy as the other way round. Every disclosed purchase and sale counted in total, by year, by party, by the dollar ranges on the filings, and over the latest 90 days of reports. Computed live.
- [Does the House or the Senate Trade More Stocks?](https://coldpine.io/research/house-vs-senate-stock-trades) (October 7, 2026): The House discloses more transactions in total and the Senate more per member. Both chambers over the same months of 2026 reports, counted in total, per trading member and per seat, with how long each takes to report and what the purchases did over the next 90 days against the S&P 500. Shown with and without each chamber's largest filer. Computed live.
- [How Big Are Congress's Stock Trades?](https://coldpine.io/research/how-big-are-congress-stock-trades) (October 4, 2026): Filings report every trade in a dollar range, so each one can be counted by size. About seven in ten transactions members of Congress disclose sit in the smallest range, $1,001 to $15,000, and fewer than one in a hundred is above $1 million. Every range counted four ways: all transactions, those with a ticker, without the largest filer, and member by member. Computed live.
- [Do Democrats or Republicans Trade Stocks Better?](https://coldpine.io/research/democrats-vs-republicans-stock-trades) (October 3, 2026): Every disclosed stock purchase in Congress measured over the next 90 days against the S&P 500, split by party three ways: trade by trade, without each party's largest filer, and member by member. Neither party's purchases beat the index trade for trade, about half the members in each party do, and which party looks better depends on the count. Computed live.
- [What Sectors Do Members of Congress Trade the Most?](https://coldpine.io/research/what-sectors-does-congress-trade) (October 2, 2026): Every disclosed stock trade in a sector-classified company, ranked three ways: member by member, by raw trade count, and without the one household that makes up half the count. Technology leads on every measure, energy and defense are a small slice, and Republicans lean further into financials and energy than Democrats do. Computed live.
- [Whose Trades Are They? Spouses, Children and Congress's Stock Disclosures](https://coldpine.io/research/congress-spouse-stock-trades) (October 1, 2026): Most stock trades Congress discloses are not made in the member's own account. Every disclosed trade counted by the owner named on the filing: spouse, dependent child, joint, or the member. About four in five sit in a family account, a single household accounts for more than two in five of all trades, and the typical member is closer to three in five. Computed live.
- [How to Track Congress Stock Trades](https://coldpine.io/research/how-to-track-congress-stock-trades) (September 14, 2026): Every stock trade a member of Congress makes over $1,000 becomes a public record within 45 days. Where the House and Senate publish those reports, how to read one line by line, which dates matter, and how to follow a member, a stock, or a single filing day, with the record's shape computed live.
- [Does Congress Sell Before the Drop?](https://coldpine.io/research/does-congress-sell-before-the-drop) (September 12, 2026): Is a congressional sale a warning? We measured every disclosed sale since 2023 against the next 30 and 90 days, side by side with the purchases and the S&P 500 over the same windows. What members sold went on to do about the same as what they bought, and the biggest drops on the list came after sales made in the middle of a collapse.
- [Which Party Files Late? STOCK Act Compliance by Party](https://coldpine.io/research/which-party-files-late) (September 10, 2026): Republicans miss the STOCK Act's 45-day disclosure deadline more often than Democrats in every way we count it, but the size of the gap depends entirely on the frame. Two Republican senators account for half of their party's late filings, and one Democrat's on-time volume dominates his party's total. Both frames, computed live.
- [The Biggest Cluster Buys in Congress Right Now](https://coldpine.io/research/biggest-cluster-buys-in-congress) (August 28, 2026): When three or more members of Congress buy the same stock inside a 90-day window, we call it a cluster. Every active buy cluster, the members in each, how many still stand without the most active filer, and the sell clusters alongside, computed live from STOCK Act filings.
- [Who Files Late? STOCK Act Deadline Compliance, Ranked](https://coldpine.io/research/congress-stock-act-late-filers) (August 25, 2026): The STOCK Act gives members of Congress 45 days to disclose a trade. Most beat the deadline comfortably; a meaningful slice do not, and a small group of members misses it almost every time, sometimes by years. Here is the compliance record, member by member, from the filing dates themselves.
- [What Stocks Do Before Congress Discloses](https://coldpine.io/research/what-stocks-do-before-congress-discloses) (August 2, 2026): Members of Congress can wait up to 45 days to tell the public about a trade. We measured what more than ten thousand disclosed purchases did between the trade date and the disclosure date, against the S&P 500 over the same window. The average is smaller than you'd guess, and the late filers are not.
- [Every Stock Nancy Pelosi's Household Has Traded](https://coldpine.io/research/nancy-pelosi-stock-trades) (July 7, 2026): Every stock on Nancy Pelosi's financial disclosures, all of them listed under her spouse: the names traded most, how many purchases are call options, how fast she files, and how the purchases did against the S&P 500, computed live from STOCK Act filings.
- [Which AI Stocks Is Congress Buying?](https://coldpine.io/research/ai-stocks-congress-is-buying) (July 7, 2026): The AI-linked stocks members of Congress disclose buying most, from a basket of 26 chipmakers, cloud platforms and AI software names: purchases, sales and buyers per stock, the share of all their purchases, how much rests on the largest filer, and the latest 90 days of reports. Computed live from STOCK Act filings.
- [Which Members of Congress Own SpaceX?](https://coldpine.io/research/which-members-of-congress-own-spacex) (July 6, 2026): SpaceX went public on June 12, 2026 as SPCX, one of the most anticipated IPOs in years. At least two members of Congress own it, one who got in before the IPO and one who bought after. Here's who, from STOCK Act filings.
- [Which Members of Congress Own xAI?](https://coldpine.io/research/which-members-of-congress-own-xai) (July 6, 2026): xAI, Elon Musk's private AI company behind Grok, isn't public, so almost no one can buy it. At least one member of Congress has disclosed a stake. Here's who owns xAI, from STOCK Act filings.
- [Which Members of Congress Actually Beat the Market](https://coldpine.io/research/members-who-beat-the-market) (June 16, 2026): Trading often is not the same as trading well. Most members of Congress do not beat the S&P 500 on their disclosed purchases. Here are the few who do, measured by 90-day alpha vs SPY.
- [The Most Active Stock Traders in Congress](https://coldpine.io/research/most-active-traders-in-congress) (June 16, 2026): A small group of members accounts for an outsized share of all disclosed trading. Here are the ten most active, ranked by disclosed trades, straight from STOCK Act filings.
- [What Is the STOCK Act? Congressional Stock Trading, Explained](https://coldpine.io/research/what-is-the-stock-act) (June 29, 2026): The STOCK Act is the 2012 law that requires members of Congress to disclose their stock trades. What it covers, what it requires, how disclosure actually works, and why enforcement is so weak.
- [Does Congress Actually Beat the Stock Market?](https://coldpine.io/research/does-congress-beat-the-market) (June 29, 2026): Members of Congress are often assumed to be savvy traders. Measured against the S&P 500 over the 90 days after each disclosed purchase, most are not. Here is the data, and the few exceptions.
- [The Most-Traded Stocks in Congress](https://coldpine.io/research/most-traded-stocks-in-congress) (June 29, 2026): Which stocks show up most across Congressional disclosures: the names members buy and sell the most, straight from STOCK Act filings and ranked by Coldpine.

## How it works
- Data is ingested continuously from the House Clerk (financial disclosure PDFs) and the Senate eFD portal (HTML and scanned paper filings), parsed into structured transactions, scored, and published within hours of being disclosed.
- Every transaction links back to the original government filing on house.gov or senate.gov.
- Publisher masthead at https://coldpine.io/about: who publishes Coldpine (Coldpine LLC, independently owned, no sponsored content), how reports are parsed and published, its editorial standards (descriptive never advisory, every return paired with the market over the same window), its corrections route (hello@coldpine.io, checked against the source filing), how to read the filed date versus the published date, and how to cite a page.
- Coldpine maintains public, indexable pages for hundreds of members (at /politicians/) and hundreds of tickers (at /stocks/) drawn from the same disclosure data.
- Senate hub at https://coldpine.io/politicians/senate: every U.S. Senator with a periodic transaction report on file since 2023, ranked by disclosed trades, with a chamber summary (senators on record, trades, buys and sales, trades filed past the 45-day deadline and which senators account for them, reports filed, last report).
- House hub at https://coldpine.io/politicians/house: every member of the U.S. House of Representatives with a periodic transaction report on file since 2023, ranked by disclosed trades with party and district on every row, with the same chamber summary (members on record, trades, buys and sales, late-45 count and how it is spread across the roster, reports filed, last report).
- State pages at https://coldpine.io/politicians/state (index) and https://coldpine.io/politicians/state/{code} (for example /politicians/state/tx): every U.S. Senator and Representative from that state with a periodic transaction report on file since 2023, split by chamber and ranked by disclosed trades, with a state summary (members on record, trades, buys and sales, late-45 count and share, reports, last report) and the member who accounts for the largest share of the state's trades.
- Every parsed Periodic Transaction Report has its own page (at /filings/) with the member, the trades disclosed, tickers, amount ranges, and disclosure lag. The dated, newest-first index is at https://coldpine.io/filings. Every filed date also has a page at https://coldpine.io/filings/day/YYYY-MM-DD (for example /filings/day/2026-09-09) listing every report filed that day with the day's trade count, buy and sale split, most-traded tickers, and how many trades were reported past the 45-day deadline.
- Weekly data drop at https://coldpine.io/data/this-week: one Monday-to-Sunday filing week, counted and stated in one place (reports filed and by how many members, trades disclosed with the buy/sale split, distinct tickers, the disclosed value as the floor and ceiling of the reported brackets, trades filed past the STOCK Act's 45-day deadline, median disclosure lag, who filed, what they traded, the tickers more than one member touched, and the largest disclosed trades). Permanent URL, rewritten every Monday once the week closes, free to cite with a link back. Every earlier week keeps its own permanent page at https://coldpine.io/data/week/YYYY-MM-DD (keyed by the week's Monday), and https://coldpine.io/data indexes all of them with per-week counts.
- Feeds of the newest parsed filings: RSS 2.0 at https://coldpine.io/feeds/filings.xml and JSON Feed 1.1 at https://coldpine.io/feeds/filings.json (50 newest reports, one descriptive item per filing with the member, trade count, buy/sale split, tickers and the 45-day check; JSON items carry a `_coldpine` object with the structured counts). Refreshes with the site's one-hour cache; poll hourly.
- Google News sitemap of filing pages published in the last 48 hours: https://coldpine.io/sitemap-news.xml (publication name Coldpine, one <news:news> entry per filing page and per day roundup, publication_date = when Coldpine parsed and published the report).
- ZIP code lookup at https://coldpine.io/delegation: enter a ZIP and see the two senators and the House member who represent it as they appear in the STOCK Act record since 2023 (trades disclosed, late filings, most-traded stock, last report). Members with no periodic transaction report on file are stated as such.
