About Us

Founded in 2018, Defiance ETFs is an exchange-traded funds (ETFs) sponsor and registered investment advisor focused on thematic investing. These themes cut across traditional sectors. They include technologies or practices that are set to transform existing paradigms of how we live, work, receive healthcare and pursue leisure; and could become a $500 billion category over the next five years.1

From quantum computing to sustainable energy solutions; from blockchain to artificial intelligence and smart cars.

Funds invested in thematic ETFs now exceed those in any other industry-defined sector. Indeed at $183 billion, thematic ETFs hold more than double the value of any other single sector. And while they hold less than 2% of industry assets, they account for about 6% of revenue.2 Thematic ETFs have taken in more flows over the past three years than all other sector ETFs combined.3

Thematic investing is by definition a long-term investment strategy, providing exposure to disruptive emerging trends that will mold the categories of tomorrow.

Defiance’s first-mover thematic ETFs seek to capture the most dynamic and disruptive of these trends.
