Brian J. Mast net worth & financial disclosures

Members of Congress must file annual financial disclosure reports listing their assets, income, and liabilities — the basis for any Brian J. Mast net worth estimate. Those reports list holdings in broad dollar ranges rather than exact totals, so published net-worth figures are estimates. We link Brian J. Mast's official filings below and, rather than guess a single number, show the money we can document: campaign funding, disclosed stock trades, and votes.

Official financial disclosures: U.S. House Clerk disclosure search — search "Brian J. Mast" for the filed reports behind any net-worth estimate.
Campaign money raised: $4,308,890 (cycle 2026) — see who funds Brian J. Mast below.
Disclosed stock trades: 87 transactions across 33 tickers — see stock trades below.

Net-worth estimates derive from congressional financial disclosures, which report value ranges. Figures here are documented campaign and trading disclosures, not a personal net-worth appraisal.

About this data

Campaign finance figures are aggregated from public Federal Election Commission filings (public domain). Stock trades, lobbying, and contract figures are derived from disclosures compiled by QuiverQuant. Contributions are grouped by the donor's reported employer — they are not OpenSecrets industry clusters, and the totals combine individual contributions with affiliated PAC activity where reported.

Contributions and disclosures are not proof of influence. They show who gave and what was reported, not why a member voted a particular way. Amounts reflect the cycle or as-of dates noted beside each figure and may be revised as later filings are processed.
