Hashdex’s DEFI Goes Dark, the First U.S. Spot Bitcoin ETF to Close:
Hashdex Asset Management said its NYSE Arca spot bitcoin ETF DEFI will close. According to its Aug. 3 plan and 8-K, no new creation orders will be accepted after Aug. 17 and trading will be suspended after the close on Monday, the last session. Assets were about $14.7M as of July 30. Shareholders can sell through the close; remaining bitcoin will be liquidated for cash after about Aug. 24 to Aug. 28.
How this was made

The 30-second read
Why it matters
The sponsor’s filings indicate a hard stop on creations and a trading suspension, followed by a cash liquidation distribution after remaining bitcoin is sold, with dates around Aug. 24 to Aug. 28.
Market read
For traders and allocators, DEFI’s exit changes near-term liquidity and execution risk for holders, while reinforcing that ETF survival depends on maintaining sufficient AUM to cover operating costs.
What to watch
Wind-down mechanics (cash liquidating distribution timing, bitcoin price path, and selling costs) can dominate short-term trading behavior more than the underlying thesis on bitcoin exposure.
Background
DEFI is described as the smallest US spot Bitcoin ETF, converted from a futures wrapper after the January 2024 spot approvals.
Ticker impact
Hashdex’s DEFI spot Bitcoin ETF will accept no new creation orders after Aug. 17 and trading will be suspended after the close.
Elevated volatility and liquidity risk into the Aug. 17 creation cutoff and the post-close suspension, with potential discount/premium swings versus NAV during wind-down.
The article cites sponsor 8-K and plan details: no further creations, trading suspension after the close, and a later cash liquidating distribution tied to remaining bitcoin sales and costs.
Market effects
Signals that sub-scale spot Bitcoin ETF share classes can be delisted or wound down when operating costs exceed inflow capacity.
US-listed spot Bitcoin ETF complex faces incremental supply of shares as DEFI exits, though the article frames it as small versus larger peers.
Limited direct global impact; the main effect is within the US spot Bitcoin ETF product lineup and allocator behavior.
Counterpoint
The closure is framed as scale-driven, so it may not imply broader weakness for the spot Bitcoin ETF complex beyond the smallest wrapper.
