Bitcoin ETFs See $462.7M Outflows as Institutional Capital Shifts to Ethereum

Key Facts

1US spot Bitcoin ETFs recorded $462.7 million in net outflows last week, ending a three-week inflow streak.

2Ethereum ETFs attracted $196.9 million in net inflows during the same period.

Amid a notable shift in institutional risk appetite, US spot Bitcoin ETFs experienced significant selling pressure, ending a three-week streak of positive inflows. According to reports, these instruments recorded $462.7 million in net outflows last week, with Thursday alone witnessing $282.7 million in exits—the heaviest daily withdrawal since July. This reversal suggests a potential tactical repositioning by institutional investors following a prolonged period of Bitcoin dominance.

In stark contrast to Bitcoin's performance, spot Ethereum ETFs demonstrated resilience by attracting $196.9 million in net inflows during the same period. BlackRock’s iShares Ethereum Trust led the surge with $148.8 million in fresh capital, while the ARK 21Shares Bitcoin ETF saw the most substantial redemptions on the Bitcoin side, totaling $234.2 million. These moves occur as market data indicates Ethereum's market share has expanded by over 25% quarter-over-quarter, significantly outpacing Bitcoin's 1.5% growth in the same timeframe.

Looking ahead, traders are monitoring Ethereum's ability to penetrate and maintain levels above the $2,531 to $2,567 resistance corridor to confirm genuine momentum. As of the September 15, 2026 snapshot, with authoritative price data unavailable, the focus remains on whether this institutional capital rotation persists. Market participants will also be watching upcoming global economic catalysts, including inflation data and central bank signals, for broader direction.
