F/m Investments has applied to the U.S. Securities and Exchange Commission (SEC) for an exemption to introduce blockchain technology for recordkeeping of some existing shares of its $6.3 billion U.S. 3-Month Treasury Bill ETF (TBIL). The firm aims to test the feasibility of securities tokenization within a regulated framework without altering the product's structure, investment targets, or trading methods. Founded in 2018, F/m Investments currently manages approximately $18 billion in assets.
