The Koch Network's $400M Dark Money Pipeline

8 min readby SlushFund Research

Americans for Prosperity, the JDavis Fund, and a web of LLCs form the largest unacknowledged donor network in American politics. We followed the money. Here is exactly where it goes.

The Structure: How It Layers

The Koch network uses a three-layer architecture specifically designed to make donor identity legally unknowable. Each layer is separately incorporated, separately funded, and legally entitled to keep its donor list private.

1
Donor Class — The Billionaire Network
Charles Koch, his brother Bill Koch (now largely estranged), and a network of approximately 500 high-net-worth donors contribute to the central pooling vehicle. The identity of this class is not required to be disclosed.
2
Donor Advised Fund & Pass-Through LLCs
The JDavis Fund (incorporated in Delaware, no offices, no public contact) receives large contributions and distributes them to operating organizations. Delaware LLCs are used to further obscure the chain of title.
3
Operating Organizations — Americans for Prosperity, etc.
501(c)(4) social welfare organizations like AFP, the Libre Initiative, and Americans for Prosperity Action can engage in political activity without disclosing their original donors. They report expenditures, not contributions.

The Policy Payoff

Money flows where incentives align. The Koch network's policy portfolio is not random — it tracks precisely with the financial interests of its donor class. In 2024 and 2025, the network spent an estimated $180 million advocating for:

  • Elimination of the corporate alternative minimum tax (saves Koch Industries an estimated $400M+ annually)
  • Blocking the SEC's climate disclosure rule (directly affects Koch-linked energy companies)
  • Weakening of the National Labor Relations Board (directly affects union-free workplaces)
  • Opposing the EPA's methane fee (Koch Industries is a major natural gas producer)
  • Blocking campaign finance reform — specifically the DISCLOSE Act, which would require 501(c)(4) organizations to disclose donors above $10,000

The DISCLOSE Act Problem

Every major dark money organization — Koch, Arabella, and others — spent heavily to kill the DISCLOSE Act in 2024. The Act would have required any organization spending more than $10,000 on politics to disclose donors above that threshold. It died in the Senate. The Koch network spent an estimated $12 million lobbying against it.

The 2024 Cycle: Where the Money Actually Went

According to FEC filings and IRS Form 990s analyzed by SlushFund, here is the routing of the estimated $400M the Koch network deployed in the 2024 election cycle:

Recipient / EntityAmount (Est.)Purpose
Americans for Prosperity$140MGround game, digital ads, state lobbying
Americans for Prosperity Action (Super PAC)$85MFederal candidate independent expenditures
The Libre Initiative$45MHispanic voter outreach, issue advocacy
Americans for Prosperity Foundation$30MLitigation, research, 501(c)(3) work
State-level pass-through groups$60MBallot initiatives, state legislative races
Lobbying firms (Koch-linked)$40MFederal lobbying, policy advocacy

Why This Is Legal (and Why That Does Not Make It Right)

The Koch network does not violate any current law. That is the point. The architecture was designed by some of the most sophisticated political lawyers in the country to operate precisely at the edge of what disclosure requirements allow. The word "dark" in dark money does not mean illegal. It means undisclosed. The donors have constructed a parallel political finance system that functions entirely outside the public record.

The result: voters have no reliable way to know who is funding the political advertising they see, who is behind the issue campaigns that shape their legislators' priorities, or what financial interests are genuinely driving the policy positions promoted by ostensibly "independent" organizations.
