Senator Cynthia Lummis (R-WY) presents an unusual profile: her self-dealing exposure centers almost entirely on a single asset class, Bitcoin, rather than traditional stock trading. She bought Bitcoin in 2013 (pre-Senate) on the advice of her son-in-law, a Bitcoin-industry executive, and now holds roughly $100K-$250K in BTC while chairing the Senate Banking Subcommittee on Digital Assets and sponsoring the BITCOIN Act to create a federal Strategic Bitcoin Reserve, an unusually direct overlap between a personal asset and the policy she champions that ethics watchdogs have called a conflict of interest. She receives concentrated crypto-industry campaign money that aligns with her legislative agenda (correlation, not proof of a quid pro quo). Much of her wealth predates office (ranching, real estate, prior elected roles) and her net worth has been broadly stable; no campaign personal-use complaints or staff-to-lobbyist pipeline were found in public records, and she disclosed her Bitcoin holdings, albeit with a self-reported 2021 filing error.

Amounts are the ranges members must report, not exact values. The STOCK Act requires a report within 45 days of a trade; "late" counts days past that deadline, measured to the filing date.

Stock self-trading
25% weight
32
Lummis does not appear to be an active individual-stock trader; her notable holding is Bitcoin (~5 BTC, disclosed at $100K-$250K), a commodity rather than a stock. The relevant concern is asset-policy overlap, not trade volume: she chairs the Banking Digital Assets Subcommittee and sponsors the BITCOIN Act while personally holding the asset. She disclosed her August 2021 BTC purchase ($50K-$100K) via a late PTR her office attributed to a 'filing error.' No evidence of frequent committee-timed equity trades or market-beating churn; score reflects the holding-while-legislating overlap, not trading behavior.
Lummis entered the Senate already wealthy from ranching, real estate, and prior elected office, and her Bitcoin position dates to 2013, pre-Senate. OpenSecrets-derived estimates place her net worth broadly in the $5.7M-$24M disclosure range, roughly stable over her tenure. Bitcoin appreciation reflects market movement on a pre-office asset rather than salary-anomalous growth. No documented enrichment beyond salary plus market is available, so per the rubric this scores 0 (absence is not penalized).

Correlation, not proof. Lummis is the Senate's most prominent crypto advocate and receives concentrated contributions from crypto VCs and executives (e.g., Andreessen Horowitz's Ben Horowitz and Chris Dixon, Multicoin Capital's Kyle Samani, Kraken's chief legal officer, Pantera) while sponsoring/co-sponsoring industry-aligned legislation (BITCOIN Act, GENIUS Act). The donor-vote alignment is unusually tight given her subcommittee chairmanship, but no evidence of an explicit quid pro quo exists; this measures concentration and directional alignment only.
No FEC complaints, enforcement actions, or credible reporting alleging personal use of campaign or leadership-PAC funds were found in public records. Per the rubric, absence of evidence is not penalized; scored 0.
The notable tie is familial rather than a classic staff-to-lobbyist pipeline: Lummis's son-in-law, Will Cole, is a Bitcoin-industry executive (chief product officer at Unchained, and founder of Bitcoin payments firm Zaprite) who advised her 2013 BTC purchase. Watchdogs and a canceled Ripple meeting raised concern that his Bitcoin-maximalist views may shape her Bitcoin-favoring policy. No documented direct financial contracts between Lummis's office and Cole's firms, and no significant staff-to-lobbyist pipeline was found; score reflects the family-industry conflict, not proven contracting.
Lummis's specific 2024 missed-votes percentage could not be retrieved (GovTrack page returned access errors), and no reporting indicates an abnormal absenteeism pattern or a heavy paid-speech/honoraria practice tied to fundraising. With no confirming data, scored 0 per the rubric.
