Tracking Senator Susan Collins' Net Worth: Recent Market Gains and Investment Portfolio

Recent market performance has boosted Senator Susan M. Collins’ financial standing, with her investment portfolio demonstrating significant activity over the past several years. According to tracking data from Quiver Quantitative, Collins maintains a diverse collection of publicly traded assets, reflecting strategic positioning in both established corporations and high-growth technology companies.

Susan Collins’ Asset Portfolio and Net Worth Standings

Based on the latest financial disclosures, Senator Susan Collins’ net worth stands at approximately $5.9 million, positioning her at the 121st highest net worth among members of Congress. Her publicly tracked investment holdings total around $3.5 million across various equity positions. This portfolio composition reveals a notably tech-forward investment strategy, with substantial allocations to semiconductor and enterprise software companies that have delivered strong long-term returns.

The data underlying these figures comes from comprehensive STOCK Act filings, which provide transparency into trading activity by elected officials. These records show that Collins has been making deliberate investment decisions over an extended period, with some positions dating back more than a decade.

Investment Activity: A Look at Collins’ Stock Holdings

Collins’ trading history reveals several major equity positions established over the years. A significant early purchase occurred in February 2015 when she invested up to $50 million in 3M (MMM), a position that has appreciated 6.28% since the purchase date. This reflects a preference for established industrial companies with broad market exposure.

More recent activity demonstrates a clear pivot toward technology stocks. A January 2022 investment of up to $50,000 in NVIDIA (NVDA) has since surged 367.74%, showcasing the substantial gains from positioning in artificial intelligence and semiconductor leaders. Similarly, a December 2016 purchase of Tractor Supply (TSCO) stock worth up to $50,000 has grown by 228.99%, indicating successful timing in the agricultural and consumer discretionary sectors.

Historical records also document earlier sales, including the disposition of Dunkin’ (DNKN) and Red Hat (RHT) positions, suggesting a portfolio that undergoes periodic rebalancing and adjustment based on market conditions.

Campaign Fundraising and Political Activity

Beyond investment activity, Collins’ recent political fundraising efforts have generated substantial momentum. Her Q1 2025 FEC disclosure revealed $570,500 in campaign contributions, primarily sourced from individual donors comprising 76.2% of total receipts. This fundraising total ranked among the higher reported figures for the quarter across all congressional campaigns.

In terms of deployment, Collins reported campaign spending of $203,800 during the same period, with $3.2 million in cash reserves available for ongoing political operations. These figures demonstrate robust financial capacity for legislative activities and constituent outreach.

Senator Susan Collins’ financial profile—combining a diversified investment portfolio with active political fundraising—illustrates how contemporary elected officials balance personal wealth management with their public service responsibilities.
