Key Takeaways
- • U.S. spot Bitcoin ETFs suffered $265.4 million in net outflows on July 31, 2026, reversing the previous session's $233.1 million inflow and ending a brief recovery streak amid Fed rate concerns.
- • Ethereum ETFs posted a marginal $9 million net inflow on July 31, but the gain was heavily concentrated in BlackRock's ETHB (staked Ethereum fund), which alone captured $15.4 million—indicating a lack of broad-based rotation into Ether products.
- • BlackRock's IBIT (Bitcoin) lost $122.7 million, Fidelity's FBTC lost $54.8 million, and Grayscale's GBTC lost $52.6 million on the day, with every displayed Bitcoin product showing flat or negative performance.
- • Over a 10-day window (July 20–31), Ethereum ETFs gained $113.8 million while Bitcoin ETFs lost $27.6 million, suggesting modest relative strength but insufficient evidence of sustained capital rotation.
- • BlackRock's ETHB reported $546.1 million in net assets with a 1.67% trailing 30-day staking rewards rate, but concentrated inflows in a single product do not confirm market-wide Ethereum dominance or signal a durable shift in institutional demand.
Summary
U.S. spot Bitcoin ETFs experienced a sharp reversal on July 31, 2026, posting $265.4 million in net outflows after gaining $233.1 million the previous session. This marks a setback for Bitcoin products, which had staged a limited recovery in late July following a prolonged period of outflows. The sell-off reflects ongoing uncertainty surrounding Federal Reserve policy, a persistent headwind for risk assets including cryptocurrency-linked investments.
The outflow was broad-based across Bitcoin's largest products. BlackRock's IBIT lost $122.7 million, Fidelity's FBTC declined by $54.8 million, and Grayscale's GBTC shed $52.6 million. Smaller Bitcoin products including BITB and ARKB each lost approximately $17–18 million. Every Bitcoin ETF displayed in available performance data showed either flat or negative trading activity on the day.
Ethereum ETFs, by contrast, posted a $9 million net inflow on July 31, extending a period of relative outperformance versus Bitcoin. However, this gain masks significant concentration risk. BlackRock's recently launched ETHB (iShares Staked Ethereum Trust ETF) accounted for $15.4 million of the Ethereum inflow, while competing Ethereum products—including Fidelity's FETH, 21Shares' ETHW, and Grayscale's mini Ether trust—combined to lose $6.4 million. Without ETHB's inflow, the broader Ethereum ETF complex would have posted a net outflow. ETHB's 1.67% trailing 30-day staking rewards rate provides yield differentiation, but a single fund's performance does not validate a sustained shift in capital allocation.
Over a wider 10-session window (July 20–31), Ethereum ETFs accumulated $113.8 million in net inflows while Bitcoin ETFs lost $27.6 million, suggesting modest relative momentum. However, a five-day period (July 24–30) showed Bitcoin funds losing $36.2 million and Ethereum products losing $69.7 million—indicating that gains remain fragile and lack the persistence required to confirm a meaningful rotation from Bitcoin to Ether. The concentration of Ethereum strength in BlackRock's newly launched staking product, combined with outflows across rival Ethereum platforms, points to product-specific inflows rather than broad institutional reallocation toward Ethereum as an asset class.
