About Cascade Investment LLC
Cascade Investment LLC is the private holding company and family office that holds the majority of Bill Gates's fortune outside Microsoft. Headquartered in Kirkland, Washington, it is controlled by Gates as chairman and has been managed by chief investment officer Michael Larson since 1994; it is the successor to Gates's earlier investment vehicle, Dominion Income Management.
Cascade is known for concentrated, long-held anchor stakes in "essential industries" — including Ecolab, Canadian National Railway, Republic Services, Deere & Company, and one of the largest private U.S. farmland portfolios — rather than active trading. It sits inside a clearly documented multi-entity structure overseen by Cascade Asset Management Company, which manages both Gates's personal assets and the endowment supporting the Gates Foundation.
