Spot Bitcoin exchange-traded funds recorded $85.85 million in net inflows on June 12, with Blackrock's iShares Bitcoin Trust (IBIT) accounting for approximately $57.7 million of the total, according to data tracked by Sosovalue. The inflow followed a week in which the 12 tracked Bitcoin funds lost more than $1.67 billion, and none of the products posted net outflows on June 12. Spot Ethereum ETFs recorded $4.95 million in net outflows on the same day, marking a fourth consecutive session of withdrawals and widening the 2026 gap in institutional demand between Bitcoin and Ethereum products.
IBIT Captures Two-Thirds of Bitcoin ETF Inflow on June 12
Blackrock's iShares Bitcoin Trust took in about $57.7 million on June 12, equivalent to roughly 907 BTC and representing close to two-thirds of the day's total inflow across all Bitcoin ETF products. Fidelity's FBTC and the remaining funds split the balance. None of the 12 products posted a net outflow, a breadth measure that market participants monitor as a potential signal that selling pressure is easing.
The June 12 inflow followed a multi-day outflow streak during which the 12 tracked Bitcoin funds hemorrhaged more than $1.67 billion, one of the heavier drawdowns of 2026. On June 11, the funds lost $19 million, with IBIT logging its first inflow of that week. The day's Bitcoin inflow equated to roughly 1,350 BTC based on the data tracked by Sosovalue.
Ethereum ETFs Record Fourth Consecutive Day of Outflows
Spot Ethereum ETFs logged approximately $4.95 million in net outflows on June 12, marking a fourth straight day in the red. The continued withdrawals from Ethereum products contrast with the inflow pattern observed in Bitcoin ETFs on the same day. Spot Ether ETFs, approved more recently than their Bitcoin counterparts, have struggled to attract the same sustained institutional demand, and the four-day outflow run extends a softer stretch for the second-largest crypto asset.
The divergence between Bitcoin and Ethereum ETF flows has been a recurring theme throughout 2026, with Bitcoin products repeatedly outpacing Ethereum funds in net flows. Analysts have described a "winner-take-most" dynamic in the Bitcoin ETF market, in which Blackrock and Fidelity dominate flows while smaller issuers play supporting roles.
ETF Flow Data Reflects Institutional Sentiment Toward Crypto Assets
ETF flows function as a real-time gauge of institutional sentiment toward crypto because the funds buy and sell actual Bitcoin to match investor demand. Sustained inflows can tighten available supply, while heavy outflows can add selling pressure to the spot market. A single $86 million day does not reverse a $1.67 billion weekly outflow, but a session with zero funds posting net outflows is read by analysts as a tentative sign that selling has exhausted itself.
Bitcoin ETF flows have whipsawed throughout 2026, swinging from double-digit outflow streaks to sharp single-day inflows and back, often led by the same one or two large funds. Demand appears to have consolidated around the largest, cheapest, most liquid products, leaving smaller funds competing for a reduced share of flows and amplifying the impact of any single large fund's daily movements.
