Horizon Kinetics Holding Corp

Horizon Kinetics Holding Corporation is an investment advisory and independent research firm operating through its wholly-owned registered investment advisor, Horizon Kinetics Asset Management LLC. The company is a fundamental value, contrarian-oriented investment advisor. It offers investment strategies through third-party investment products, including mutual funds, third-party exchange-traded funds ("ETFs"), institutional and retail separate accounts, and other private funds and investment vehicles. Its principal executive offices are located at 470 Park Avenue South, New York, New York 10016. Horizon Kinetics' primary revenue source is advisory fee income from managing client accounts under investment advisory and sub-advisory agreements. These fees, which include both management and performance fees, are influenced by factors such as investment strategy, account size, and servicing needs. Client subscriptions and redemptions, along with market fluctuations, affect the company's assets under management and, consequently, its revenues. Assets under management were approximately $9.6 billion as of December 31, 2025, and $9.8 billion as of December 31, 2024. A key strength of the company is its culture, led by senior investors who have collaborated for over forty years, with its founders continuing to drive the investment process and culture.
