Bitcoin ETFs pull in $217 million after Friday outflow, ether ETF inflows hit 11 days

Bitcoin ETF net assets and monthly performance

By the end of August, bitcoin ETF net assets finished just under $100 billion, slightly below the threshold crossed on August 27, following Friday’s selling. Since launching in January 2024, cumulative net inflows into bitcoin ETFs have reached approximately $55 billion. August outperformed all previous months in 2026 for these funds, with results more than doubling those seen in April.

Despite the strong August rally, bitcoin ETFs continue to carry a net outflow for 2026 of about $2.5 billion. This reflects the volatility that has impacted the sector over the year, with shifts often triggered by external macroeconomic factors and investor sentiment.

Ether ETF inflows show stronger momentum

While bitcoin ETF inflows paused briefly, ether ETFs maintained steady momentum. On Monday, ether ETFs attracted $88 million in net purchases, extending their streak to 11 consecutive days and totaling $1.6 billion in net inflows. This is the longest uninterrupted buying period since a 20-day run concluded in July 2025.

The continued strength in ether ETF inflows contrasts with bitcoin products, highlighting investor interest across major digital assets. Monitoring these trends will provide further insight into shifting market dynamics and portfolio allocation strategies.

Drivers behind ETF flows

Analysts noted that Friday’s outflow in bitcoin ETFs followed monetary policy comments by former Federal Reserve Governor Kevin Warsh during the Jackson Hole symposium, which raised expectations of future interest rate hikes. The subsequent rebound on Monday was interpreted as investors treating the sell-off as a temporary adjustment.

Despite short-term volatility caused by policy expectations, allocators signaled confidence by returning to bitcoin ETFs immediately following Friday’s pause, leaving this week’s upcoming data releases as the determining factor for the prevailing trend.
