U.S. spot Bitcoin exchange-traded funds recorded their first-ever half-year net outflows since launch, according to a DWF Labs report, marking a major shift in the market structure that helped drive Bitcoin’s 2024 and 2025 institutional rally.
DWF Labs said U.S. spot Bitcoin ETFs posted approximately $5.4 billion in net outflows during the first half of 2026. That is the first half-year period in which the category finished negative since spot Bitcoin ETFs began trading in January 2024. Previous half-year periods had produced net inflows, reinforcing the view that ETFs were a structural source of demand for Bitcoin.
The reversal was most visible during a record outflow streak between May 15 and June 3, when spot Bitcoin ETFs suffered 13 consecutive trading days of redemptions. CoinDesk reported that the funds lost more than $4.4 billion during that run before recording a small $3.05 million inflow on June 4. DWF Labs also noted that BlackRock’s IBIT, once the largest source of ETF inflows, saw roughly $5 billion of net redemptions across May and June.
The outflow shift comes as Bitcoin has weakened sharply from its late-2025 highs. Reuters reported this week that Citi cut its 12-month Bitcoin price target to $82,000 from $112,000, citing weaker ETF demand, declining investor appetite and stalled U.S. crypto legislation. Citi also reduced its 12-month ETF inflow assumption to zero from $10 billion.
ETF Bid Turns Into Market Headwind
The first-half outflow data challenges one of the most important assumptions of the post-ETF Bitcoin market: that regulated funds would provide persistent institutional demand and help reduce downside volatility.
That assumption worked during earlier inflow cycles, when ETF issuers absorbed large amounts of Bitcoin and helped support the asset’s rise. But the same structure can amplify pressure when investors redeem shares. ETFs do not only transmit inflows into Bitcoin; they also transmit withdrawals when advisers, hedge funds, institutions or retail allocators reduce exposure.
The shift in IBIT flows is especially important. BlackRock’s fund became the flagship product for institutional Bitcoin access, and its inflows were often treated as a signal of mainstream adoption. Redemptions from IBIT therefore carry more psychological weight than outflows from smaller products, because they suggest demand has weakened even at the highest-quality distribution channel.
The data also shows that ETF flows have become a marginal price driver. When redemptions cluster over several weeks, market makers and authorized participants must manage underlying exposure, creating a direct link between fund flows and spot-market liquidity.
Ether ETFs Also Turn Negative
DWF Labs said U.S. spot Ether ETFs also recorded their first half-year net outflows since launch, with approximately $1.47 billion in net redemptions during H1 2026. That indicates the weakness is not limited to Bitcoin, but reflects a broader reduction in regulated crypto exposure.
Some capital has continued rotating into specific Ether products tied to staking-yield narratives, but the overall direction remains defensive. Investors are reducing crypto allocation at a time when macro uncertainty, higher opportunity costs and renewed interest in artificial intelligence equities have weakened appetite for volatile digital assets.
For the broader market, the first-ever half-year outflow is more than a statistical milestone. It shows that the ETF channel has matured from a one-way adoption story into a two-way liquidity mechanism. That is healthy from a market-structure perspective, but it also means Bitcoin is more exposed to traditional allocation cycles, risk budgets and portfolio rebalancing decisions.
The next test is whether July flows stabilize after the heavy June redemption period. If outflows slow, the first-half drawdown may be treated as a reset after an overheated institutional cycle. If redemptions continue, ETFs could remain a structural drag on Bitcoin prices and weaken confidence in the broader digital asset recovery.
