Proshares Trust
A family of exchange-traded funds (ETFs) built around leveraged and inverse strategies, ProShares lets everyday investors multiply or reverse the daily moves of major market indexes. The firm grew out of the ProFunds Group, founded in 1997 by Michael Sapir and Louis Mayberg, and launched its ETF lineup in 2006. In 2021 it made history by listing BITO, the first Bitcoin-linked ETF in the United States.
