The National Pipeline The Arabella Advisors network is the largest dark money infrastructure in the United States, with roughly $5 billion in total revenue between 2019 and 2022 flowing through four managed nonprofits: the Hopewell Fund, New Venture Fund, Sixteen Thirty Fund, and Windward Fund. Major institutional funders include the Berger Action Fund (Swiss billionaire Hansjörg Wyss, the largest identified donor), the Susan Thompson Buffett Foundation ($27 million to Hopewell Fund in 2018 alone), the Open Society Foundations, and others. In November 2025, Arabella rebranded as Sunflower Services; its operations remain functionally unchanged.
Tax filings trace a specific pipeline from this network into Montana. The Hopewell Fund granted $18.4 million to Global Impact of Alexandria, Virginia (Form 990, Schedule I). Global Impact’s 501(c)(4) subsidiary, the Global Impact Social Welfare Fund (GISWF), then pushed money into Montana through two branches: $2 million to the Western Futures Fund (a Wyoming 501(c)(4) with no donor disclosure), and $500,000 to Way Back PAC (also Wyoming-based). Western Futures Fund also fed $150,000 to Way Back PAC, meaning both branches draw from the same upstream source. This pipeline has been active for at least two election cycles, with Western Futures Fund contributing $100,000 to Montana Values Action Fund as far back as 2022.
