U.S.-listed spot-Bitcoin ETFs ended July with $172.4 million in net inflows, reversing two straight months of withdrawals, but a $265.4 million outflow on July 31 pushed weekly flows negative and underscored how fragile institutional demand remains. Fund-level data from the final trading day showed losses across every listed Bitcoin product, led by BlackRock's IBIT at $122.7 million, Fidelity's FBTC at $54.8 million and Grayscale's GBTC at $52.6 million, with BITB and ARKB each shedding roughly $18 million. Spot-Ether ETFs posted a $9 million net inflow that day, but the gain was entirely due to BlackRock's iShares Staked Ethereum Trust ETF, or ETHB, which brought in $15.4 million while FETH, ETHW and Grayscale's mini Ether trust lost a combined $6.4 million and the remaining displayed products were flat. Over the five sessions from July 24 through July 30, Bitcoin funds lost $36.2 million and Ethereum funds lost $69.7 million, while the broader 10-session period from July 20 through July 31 favored Ethereum with $113.8 million in inflows against $27.6 million in Bitcoin ETF outflows. BlackRock reported about $546.1 million in net assets for ETHB on July 31, when its NAV fell 2.85% to $24.04, and listed a trailing 30-day staking rewards rate of 1.67%, a backward-looking figure rather than a guaranteed yield. An iShares filing said the aggregate staking fee was 10% of gross staking consideration as of April 15, with staking consideration net of that fee intended for distribution monthly, but no less frequently than quarterly. The mixed ETF flows came alongside a weaker broader market, with Bitcoin near $62,958 and Ethereum at $1,868 on August 1, though the pricing snapshots were refreshed after the ETF session and do not establish causation. The latest data suggest July 31 reflected concentrated demand for one staked Ether wrapper rather than a broad rotation out of Bitcoin and into Ethereum.
