Hashdex to close its smallest US spot Bitcoin ETF after two years due to low assets.

Hashdex Asset Management is shutting down its spot Bitcoin ETF, DEFI, after two years of operation due to low investor interest and assets never exceeding $18 million. The ETF, which held actual Bitcoin rather than futures, will stop trading on August 17, 2026, with investors receiving cash payouts after liquidation. This closure highlights the competitive nature of the US Bitcoin ETF market, dominated by larger players like BlackRock. Investors in small ETFs should watch asset size and liquidity closely to avoid unexpected closures and taxable events.
