What Susan Collins' Net Worth and Stock Portfolio Reveal About Senate Finances

Susan Collins’ net worth has become a subject of interest as financial tracking platforms provide real-time insight into lawmakers’ investment activities. According to Quiver Quantitative’s latest assessments from mid-2025, the senator’s financial profile tells a compelling story about how members of Congress manage their personal wealth while serving in public office.

Susan Collins’ Current Financial Standing

According to financial disclosures analyzed by Quiver Quantitative, Susan M. Collins maintained a net worth of approximately $5.9 million as of May 2025, placing her at the 121st position among members of Congress based on tracked wealth estimates. Of this total, roughly $3.5 million was invested in publicly traded securities that financial platforms can monitor in real time. This positions her as a moderately wealthy member of Congress, reflecting years of careful financial management alongside her political career.

The senator’s asset allocation shows a clear preference for publicly traded equities over other investment vehicles, which aligns with transparency requirements under the Stock Act—legislation that mandates lawmakers to disclose their securities transactions.

Portfolio Deep Dive: How Her Stock Picks Have Performed

Analysis of Susan Collins’ stock trading activities, compiled from Stock Act filings covering up to $115.8 million in transactions, reveals some notable investment patterns. Her largest historical trade occurred in February 2015, when she purchased up to $50 million in 3M Company (MMM) stock. That position has appreciated 6.28% in the years since the initial purchase.

More recently, her portfolio included several strategic positions:

• A December 2020 sale of up to $100,000 in Dunkin’ Brands (DNKN)
• A May 2019 sale of up to $100,000 in Red Hat (RHT), which has since gained 1.19%
• A December 2016 purchase of up to $50,000 in Tractor Supply Company (TSCO), which has soared 228.99% since acquisition
• A January 2022 purchase of up to $50,000 in Nvidia (NVDA), delivering impressive returns of 367.74%

These transactions demonstrate a mix of industrial, technology, and consumer discretionary holdings, suggesting a diversified approach to portfolio construction. Her Nvidia purchase proved particularly prescient given that company’s explosive growth during the AI boom that followed 2022.

Campaign Fundraising and Financial Resources

In her most recent FEC disclosure filed on April 13, 2025, Susan Collins reported $570.5 thousand in fundraising activity during the first quarter—the 100th largest total among all Q1 reports filed that year. Individual donors accounted for 76.2% of this fundraising, indicating strong grassroots support.

Against these incoming funds, she disclosed campaign spending of $203.8 thousand during the same period—the 189th highest expenditure level among all politicians’ Q1 reports. By the end of the filing period, Collins maintained $3.2 million in cash reserves available for future campaign activities, ranking 71st among all lawmakers in terms of available campaign funds.

Legislative Priorities and Public Service

Beyond her investment portfolio, Collins’ legislative agenda reflects her focus on healthcare, rural development, and quality-of-life issues. Recent bill proposals include S.1805, which would amend Medicare documentation requirements for nurse practitioners and physician assistants covering diabetic footwear; S.1077, the District of Columbia Local Funds Act of 2025; and S.830, the Lifespan Respite Care Reauthorization Act of 2025.

These policy initiatives demonstrate how her work as a senator extends well beyond financial considerations, though her Susan Collins net worth and investment decisions remain matters of public record and ongoing interest to voters and political observers tracking the financial interests of elected officials.
