How Congress Got Rich

• Key findings
• The median member is worth about $2.1M — roughly 11× the ~$192,700 typical U.S. household (Federal Reserve).
• Median disclosed wealth rose from $1.46M (2018) to $2.10M (2025); across a matched 292-member cohort it grew ~50% and 91 at least doubled.
• The ultra-wealthy tier swelled: members worth over $50M nearly tripled (6 → 17); over $10M more than doubled (23 → 54).
• The richest is Sen. Jim Justice (R-WV) at ~$1.04 billion; the rich list is bipartisan (Scott R, Issa R, Pelosi D, Warner D…).
• The growth is mostly markets and pre-existing fortunes, not trading — the median member's ~50% rise even trails a passive S&P hold. The story is the level, not skill.

1. Introduction: a millionaires' club

The United States Congress is often described as a millionaires' club, and for once the cliché understates the data. The median member — not the average, which a few billionaires distort, but the one in the middle — holds disclosed assets worth about $2.1 million. The typical American household, by the Federal Reserve's measure, is worth about $192,700. The person writing the tax code, the financial regulation, and the health-care law is, at the median, roughly eleven times as wealthy as the person they represent.

This paper does three things with that fact. It measures the gap and the distribution (§3); it tracks the trajectory from 2018 to 2025, when the wealth both grew and concentrated (§4); and it names the rich list and the biggest climbers (§5–6). Then, because the honest answer matters more than the viral one, it explains what actually drove the growth (§7) — and it is mostly not what the headlines assume.

2. Data and methodology

Members of Congress file an annual Personal Financial Disclosure (Form 278) listing each asset they and their immediate family hold, in value ranges (e.g. “$1,000,001–$5,000,000”). We estimate a member's wealth for a given year as the sum of the midpoints of those ranges, taking one filing per member per year.

The exact recipe, because v1.1 found that v1.0's description could not be rebuilt. Filings are restricted to the machine-parsed set and joined to the member roster — without that join, 147 of 2018's 425 parsed filings never matched a member and collapse into a single phantom “member.” One filing per member per year. A member's value is the sum over their asset rows of (value_min + COALESCE(value_max, value_min)) / 2 — note the COALESCE: the top asset category is open-ended (“over $50,000,000”) and carries no ceiling, so its floor stands in as its own ceiling. That convention is not cosmetic. Omit it and the over-$10M tier reads 32→57 instead of 25→54 — which would break this paper's own “more than doubled” claim on an arithmetic artefact rather than on the data.

Per-year coverage, corrected. v1.0 said the parsed set covers “224–253 members per year.” It does not. Rebuilt on the pinned recipe the range is 230 to 415 — 230 in 2018, rising through 348 (2021) to 415 (2023), and 257 for 2025, which is low only because that year's filings are still arriving. The endpoint years are the thin ones; the middle is far thicker than v1.0 claimed. It remains a large sample rather than a census, which is the point the original sentence was reaching for and got wrong.

Three honest cautions frame everything below. First, this is gross asset value, not true net worth: we do not subtract liabilities (mortgages, loans), which the disclosures report separately and sparsely, so levels are best read as order-of-magnitude. Second, brackets are wide, so midpoint sums carry real error bars; we lead with the median (robust) and report changes over matched members. Third — and most important — wealth growth is not trading profit: it is dominated by market appreciation and by spousal, private-business, and real-estate assets that have nothing to do with congressional stock trading. We measure how rich Congress is, not how it got each dollar.

3. The gap, and how concentrated it is

Two numbers carry the section. The median member's $2.1M is the typical experience — eleven times the household median — while the mean of about $18M shows how a few enormous fortunes pull the average into a different universe. Between them sits a steep distribution: of the members we parse, 171 are millionaires, 54 are worth over $10 million, and 17 are worth over $50 million.

Counts among members whose PFD assets are machine-parsed (253 in the latest year). Median member ≈ 11× the ~$192,700 U.S. household net worth (Federal Reserve Survey of Consumer Finances). Verified June 30, 2026.

4. The trajectory: richer, and more top-heavy

The wealth is not static; from 2018 to 2025 it grew and it concentrated. The median member rose from $1.46M to $2.10M. The real movement, though, is at the top: the count worth over $10M jumped from 23 to 54, and the count worth over $50M went from 6 to 17 — nearly tripling. Across a matched cohort of 292 members present in both an early (2018–2020) and a late (2024–2025) filing, median disclosed wealth grew about 50%, and 91 of them — nearly a third — at least doubled.

Matched 292-member cohort: median wealth +~50%, 91 members at least doubled. Tier counts among parsed members each year. Verified June 30, 2026.

5. The rich list

The top of Congress is a bipartisan collection of business fortunes. The single richest member, by a wide margin, is a coal magnate; the rest of the top of the list made their money in healthcare, electronics, finance, and aerospace before they made law about it.

Estimated disclosed assets (bracket-midpoint sum), latest available filing. Nine Republicans, six Democrats in the top 15 — the wealth is bipartisan. Justice (coal), Scott (healthcare), Issa (car alarms), McCormick (hedge funds), Ricketts (brokerage), Sheehy (aerospace) built fortunes before Congress. Verified June 30, 2026.

6. The biggest climbers

Who gained the most while in office? By absolute dollars, the climbers are again bipartisan — and the list separates into two kinds of story. Most of the biggest dollar gains are large portfolios growing a market-like 1.5×–1.6× (Scott, Pelosi, Buchanan); the eye-popping multiples come off smaller bases (Mullin 8.6×, Gottheimer 4.5×, Williams 3.2×).

Change in estimated disclosed assets, earliest (2018–2020) to latest (2024–2025) filing, matched members. Five Republicans, five Democrats — bipartisan. Multiples off small bases (Mullin, Gottheimer) are dramatic but represent smaller absolute dollars than the large-portfolio 1.5× gains. Verified June 30, 2026.

7. What actually made them rich

This is the section that separates analysis from outrage. It is tempting to read Table 2 as proof that office makes members rich — and tempting is exactly why it deserves scrutiny. Three forces explain almost all of the growth, and none of them is “trading on inside information.”

First, the market did most of the work. The S&P 500 roughly doubled between 2018 and 2025. Any member holding a large diversified portfolio would have seen it grow substantially while doing nothing — and the matched cohort's median growth of about 50% actually trails a simple index hold, which tells you the typical member is not beating the market; they are riding it, often through slower-moving assets like real estate. Second, the fortunes are pre-existing. The rich list is coal, healthcare, electronics, hedge funds and aerospace money that arrived before the member did. Third, the disclosures are family-wide — spousal businesses (Pelosi), private companies (Mullin's plumbing firm, Hern's franchises), and inherited holdings sit in these totals and move for reasons unrelated to anyone's vote.

8. Discussion: why the level matters

A reader might fairly ask why wealth that mostly predates office, and mostly grows with the market, is worth a paper at all. The answer is representation and conflict. A legislature whose median member is a multi-millionaire and whose top is a billionaire experiences the tax code, interest rates, health-care costs, and market regulation differently from the household at $192,700. That is true regardless of how anyone made their money, and it shapes which problems feel urgent and which trade-offs feel acceptable. And the holdings that compose this wealth — the individual stocks, the private companies, the real estate — are the raw material of every conflict-of-interest question the rest of GovGreed's work examines. This paper is the denominator under all of it: before you ask whether a member traded a stock well, it helps to know they were already, at the median, a millionaire eleven times over relative to their constituents.

9. Limitations and caveats

• Gross assets, not net worth. We sum disclosed asset-value midpoints and do not subtract liabilities (reported separately and sparsely). Levels are order-of-magnitude estimates.
• Wide brackets. Form 278 reports ranges; midpoint sums carry real error. We lead with the robust median and with matched-member changes, not precise dollar claims.
• Not a census. Coverage is members whose filings are machine-parsed (230–415/year, thinnest at the 2018 and 2025 endpoints); some high-profile members (e.g. Khanna, McCaul) have filings not yet parsed and are excluded from these tallies.
• Growth is not trading profit. Market appreciation, pre-existing fortunes, and spousal/private/real-estate assets dominate. Nothing here attributes wealth growth to congressional trading or to non-public information.
• Household comparison is external. The ~$192,700 U.S. median household net worth is the Federal Reserve's 2022 Survey of Consumer Finances, not derived from our data; it is a reference point, not an exact-year match.
• No accusation. Naming a member's wealth or its growth is reporting a public disclosure, not alleging wrongdoing.

10. Conclusion

Congress is rich, getting richer, and concentrating — the median member an eleven-times-over millionaire, the over-$50M tier nearly tripled since 2018, the top a billionaire. Most of it is the market and money that arrived before the oath, not a trading edge; the median member doesn't even beat the index. But that is the point worth keeping. The defining financial fact about the people who write America's economic rules is not how cleverly they trade. It is how far, before any trade, they already sit from the people those rules are written for.
