When the SEC approved spot Bitcoin ETFs in January 2024, it felt like a turning point. Roughly a dozen funds launched into a market hungry for regulated Bitcoin exposure. BlackRock, Fidelity, Invesco, Hashdex — the names were credible, the timing felt historic.
On August 3, the Hashdex Bitcoin ETF became the first to blink.
Hashdex Asset Management announced it would close and liquidate the fund, ticker DEFI, listed on NYSE Arca, after assets under management fell to approximately $14.7 million as of July 30. Trading ends August 17. Cash proceeds from the liquidation of roughly 225 BTC will be distributed to shareholders around August 28. It is the first closure of a U.S. spot Bitcoin ETF in history.

The economics were untenable. At its 0.25% expense ratio, $14.7 million in assets throws off only about $37,000 a year in fees — and DEFI's actual fee income was running even lower, at just $6,453 in the first quarter of 2026, an annual pace near $26,000. That is barely enough to cover the cost of operating a fund.
DEFI originally launched in September 2022 as a Bitcoin futures ETF registered under the Securities Act of 1933, before converting to a spot product in late March 2024 — nearly three months after BlackRock's IBIT had already captured the market's attention.
Flows into spot Bitcoin ETFs as a group have dwindled, with net outflows recorded in each of the past three months, according to SoSoValue data. K33 Research head Vetle Lunde framed it directly in a June report: "Much of the market views the opportunity cost of holding BTC as too high while anything AI-related soars."
BlackRock's iShares Future AI & Tech ETF gained about 39% through July and holds roughly $3.6 billion in assets, while the broader crypto market, measured by the CoinDesk 20 Index, fell roughly 36% over the same period.
DEFI's $14.7 million sat against $142.4 million in WisdomTree's BTCW, the next-smallest fund, and $47.08 billion in BlackRock's IBIT. The gap between winner and loser in this market is not competitive. It is structural.
DEFI's closure does not mean Bitcoin ETFs have failed. It means the market has already consolidated around three or four dominant products, and everything else is being squeezed out.
Bloomberg Intelligence ETF analyst James Seyffart had flagged this in advance, predicting that under-subscribed funds would likely shut down toward the end of 2026 or into 2027. The first one just did.
