Roundhill Cannabis ETF (WEED) is an actively managed exchange-traded fund that provides concentrated exposure to the largest U.S. multi-state cannabis operators (MSOs) and the global cannabis ecosystem through a portfolio of equities and total return swaps; these swaps deliver targeted investment in cannabis producers, distributors, technology companies, and ancillary businesses while maintaining compliance with regulated investment company diversification requirements. The ETF trades options, features a gross expense ratio of 0.40% (with a contractual net expense ratio of 0.00% through at least July 1, 2025), and focuses on companies benefiting from ongoing legalization trends across U.S. states and international markets. Launched on April 20, 2022, on the Cboe BZX Exchange, WEED is issued and managed by Roundhill Investments LLC, an SEC-registered investment advisor founded in 2018 and headquartered in New York.
In May 2023, the ETF executed a 1-for-5 reverse share split to adjust its share structure amid market conditions. Roundhill Investments, the ETF's sponsor, surpassed $5 billion in assets under management in June 2025, reflecting broader firm growth that supports its thematic ETF offerings, including WEED. The firm continues to expand its product lineup with new launches such as the Uranium ETF (UX) in January 2025 and various WeeklyPay™ and 0DTE covered call strategy ETFs throughout 2025, while transitioning other funds like the Video Games ETF (NERD) to active management in September 2025. These developments underscore Roundhill's strategic focus on innovative, sector-specific investment vehicles amid evolving regulatory landscapes for cannabis.
