Tuesday's ETF flow data marked a significant shift.
Bitcoin funds recorded a collective net inflow of $332.7 million, driven largely by Fidelity's FBTC ($132.7 million) and BlackRock's IBIT ($72.8 million). In contrast, spot Ethereum ETFs experienced significant outflows totaling $135.3 million, with Fidelity's FETH and Bitwise's ETHW leading the decline.
Analysts suggest that this "rebalancing" indicates that institutions are favoring Bitcoin's perceived role as a macroeconomic hedge amid current uncertainties.
This ends a notable trend in August, in which Ethereum ETFs significantly outperformed, attracting $3.87 billion compared to $751 million in Bitcoin outflows, driven by themes such as yield generation and regulatory clarity.
