US spot Bitcoin ETFs shed $61.53 million over the past week, while their Ethereum counterparts pulled in $27.42 million.

The flow breakdown

Bitcoin ETF outflows of $61.53 million represent a continuation of choppy patterns that have defined much of 2026. The week wasn’t a one-way street either. Late July saw individual days where BTC products lost between $11.6 million and $12 million, while Ethereum ETFs picked up roughly $9 million on those same days.

BlackRock’s products, including IBIT for Bitcoin and ETHA for Ethereum, continue to dominate both volume and net flow leadership. Fidelity’s FBTC and FETH trail behind, with Grayscale’s GBTC still in the mix despite its historically higher fee structure.

July 2026 was particularly bumpy for Bitcoin ETFs, with multiple days of significant outflows that totaled in the hundreds of millions on select trading sessions. Those dramatic single-day moves were frequently offset by Ethereum inflows, creating a tug-of-war dynamic that kept aggregate crypto ETF flows relatively stable even as individual products swung wildly.

Why the rotation matters

Bitcoin has been trading around the $60,000 level recently, and that price action appears to be driving much of the flow behavior. When BTC consolidates or dips, some institutional money rotates into Ethereum products as a way to maintain crypto exposure while shifting risk profiles.

The lack of any major regulatory catalyst behind these flows is telling. No new SEC guidance, no issuer-specific announcements, no structural changes to the products themselves. This appears to be pure market sentiment at work.

What investors should be watching

BlackRock’s continued leadership in both volume and inflows hints at a consolidation of market share among the largest issuers. Both Bitcoin and Ethereum ETFs have accumulated substantial cumulative inflows since their respective launches, even accounting for periodic redemption waves.
