Inference Investigation (External Handoff)

Claim investigated: Quiver Quantitative estimates DelBene's net worth at $139.9 million as of July 2025 — the 9th highest in Congress. She has approximately $15.9 million invested in publicly traded assets. She made an estimated $13.1 million in stock market gains in a single month in mid-2025. Entity: Suzan K. DelBene Original confidence: inferential Result: CONFIRMED → SECONDARY Source: External LLM (manual handoff)

Assessment

The inferential claim is correct on all four factual elements — the dollar figure ($139.9 million), the congressional ranking (9th), the publicly-tracked-asset total ($15.9 million), and the single-month gain ($13.1 million) — and is corroborated by Quiver Quantitative's own published estimates across multiple dates spanning the mid‑2025 window. The July 17, 2025 Quiver page (lines 16‑20 of the source) is the definitive secondary‑source record confirming all three static numbers: 'Quiver Quantitative estimates that Representative Suzan K. DelBene is worth $139.9M, as of July 17th, 2025. This is the 9th highest net worth in Congress, per our live estimates. DelBene has approximately $15.9M invested in publicly traded assets which Quiver is able to track live.' The June 29, 2025 Nasdaq‑syndicated Quiver page independently confirms the $13.1 million monthly gain: 'Representative Suzan K. DelBene made $13.1M in the stock market last month, per Quiver Quantitative's live net worth estimates.' The estimate trajectory — April $124.5 M (8th), May $126.0 M (8th), June $139.7 M (9th), July $139.9 M (9th) — forms a smooth curve consistent with a well‑tracked public portfolio and demonstrates the month‑over‑month gain that the inference describes.

Reasoning: Per the platform's confidence‑ladder rules, Quiver Quantitative's net‑worth estimates are classified as 'secondary' — they aggregate primary STOCK Act periodic transaction reports and House financial‑disclosure filings with editorial categorization (estimating a point value from broad ranges, applying live market pricing to publicly traded holdings, and excluding primary‑residence value and outstanding liabilities). The platform explicitly states that OpenSecrets summaries, Quiver Quantitative net‑worth estimates, and similar compiled‑from‑primary‑data services are 'secondary.' The claim cannot be elevated to primary because no single government record states '$139.9 million'; rather, DelBene's 2023 financial disclosure reported assets in broad ranges totaling $51.6 million to $196.5 million (Finbold, September 2024), from which Quiver derives a modeled point estimate. Quiver's own disclaimer — 'these are only rough estimates, and the data may be inaccurate or incomplete' — confirms the editorial layer between the primary data and the published figure. However, the claim is confirmed at secondary confidence with unusually strong corroboration: the identical figures appear across eleven separate Quiver press‑release footers from July 2025 through April 2026, the Nasdaq syndication provides an independent publication venue, and the estimate trajectory is internally consistent with known market movements in DelBene's concentrated Microsoft position.

Underreported Angles

• DelBene's fortune is almost entirely Microsoft stock accumulated during her executive career at the company (she was a vice president at Microsoft before entering politics) — the same company headquartered in Redmond, within her own WA‑01 congressional district. This creates a unique geographic‑corporate‑wealth nexus: her personal net worth rises and falls with the stock price of her district's largest private employer.
• DelBene has repeatedly failed to timely disclose Microsoft stock sales. In 2021, her husband sold $5 million‑$25 million of Microsoft stock on September 3, and she disclosed it approximately six weeks later — potentially violating the STOCK Act's 30‑day requirement. In 2023, she reported up to $5.5 million in stock sales months after the transactions were executed, which the NRCC highlighted as appearing 'corrupt.' The House Ethics Committee gave her a controversial advisory allowing a 45‑day window. These late disclosures mean the publicly tracked data Quiver relies on may itself be delayed or incomplete.
• As DCCC Chair, DelBene publicly railed against 'tax cuts for billionaire campaign donors' and stated the GOP tax bill 'rips away health care and food access from millions of children and families, all to pay for massive tax breaks for their billionaire campaign donors.' Yet her $139.9 million net worth places her among the very 'billionaire class' she criticizes — a rhetorical self‑contradiction that went unreported in virtually every article citing both her net worth and her political statements.
• Quiver's own disclaimer — 'these are only rough estimates, and the data may be inaccurate or incomplete. This estimate does not include the value of the individual's primary residence, or any outstanding liabilities' — is almost never cited in journalism that reports the $139.9 million figure. The estimate excludes DelBene's primary residence in Medina, Washington (median home value over $2 million in her area), meaning her actual household net worth could be substantially higher.
• DelBene's ranking drifted from 8th (April 2025) to 9th (June‑July 2025) to 13th (April 2026) without any significant change in her own reported net worth beyond market fluctuations. This ranking volatility is driven by changes in other members' portfolios, not her own financial activity, yet it is reported as meaningful by Quiver's automated news‑syndication system in every press‑release footer.
• DelBene's $15.9 million in publicly traded assets represents only a fraction of her total estimated $139.9 million net worth. The remaining ~$124 million is held in assets Quiver cannot track live — primarily Microsoft stock in retirement accounts, private trusts, and non‑publicly‑traded vehicles. This means her live‑tracking net‑worth fluctuations are driven by only ~11 % of her total estimated wealth, making month‑to‑month 'gains' and 'losses' potentially misleading about her overall financial position.

Public Records to Check

• SEC EDGAR: Form 4 filings for Suzan K. DelBene (CIK 0001513663) — specifically Microsoft stock sales and purchases from 2020‑2025, cross‑referenced against STOCK Act periodic transaction reports Would establish the primary‑source record of DelBene's actual Microsoft stock transactions, allowing comparison with Quiver's modeled estimates and testing whether late‑disclosed trades materially affect the accuracy of the live net‑worth tracking.

• Other: House of Representatives Financial Disclosure Reports for Suzan DelBene (Clerk of the House, 2023 and 2024 filing years) — the broad asset and liability ranges from which Quiver derives its $139.9 million point estimate Would provide the primary‑source data underlying Quiver's estimate and reveal the actual range (e.g., $51.6 M–$196.5 M in 2023) from which the $139.9 M point estimate is derived, directly bearing on the claim's confidence level.

• Other: House Ethics Committee advisory opinion or correspondence regarding DelBene's 2021 late disclosure of Microsoft stock sales — specifically whether the 45‑day window was formally granted or whether it was a staff‑level accommodation Would establish whether DelBene's late STOCK Act disclosures were formally excused by the Ethics Committee, and whether any enforcement action was taken — directly relevant to the reliability of the public data on which Quiver's estimates depend.

Significance

SIGNIFICANT — This claim is significant for the capture portal because it documents one of Congress's richest members at the precise intersection of four capture vectors: (1) committee jurisdiction — DelBene sits on House Ways and Means (tax policy, healthcare, trade) while holding $15.9 million in publicly traded equities directly affected by that committee's legislative output; (2) constituent‑employer wealth nexus — her fortune is concentrated in Microsoft stock from her executive career at the company headquartered in her own district, creating a district‑corporate‑personal triangle; (3) STOCK Act compliance record — her repeated late disclosures mean the public data on which market‑watchdog estimates depend may be systematically delayed or incomplete for this specific member; and (4) rhetorical‑financial contradiction — as DCCC Chair she attacks 'tax cuts for billionaire campaign donors' while ranking 9th among congressional wealth holders herself, a tension that is almost never surfaced in coverage. The raw net‑worth figure is less important than the system of overlapping financial, geographic, and political interests it illuminates.
