Ethereum ETFs Outpace Bitcoin in September Inflows
Ethereum spot ETFs have seen a surge in capital, recording $445 million in inflows for September and briefly outpacing Bitcoin products as institutional interest shifts.

September has seen a shift in crypto ETF flows, with Ethereum products attracting more net capital than Bitcoin ETFs through the middle of the month. While Bitcoin has historically dominated the space, Ethereum ETFs recorded approximately $324 million in net inflows through mid-September, compared to roughly $307 million for Bitcoin.
The broader picture for the month shows Ethereum ETFs pulling in around $445 million, while Bitcoin ETFs recorded $467 million. Bitcoin began the month with a strong performance, including a $731 million single-day inflow on September 3. However, the momentum stalled when Bitcoin ETFs saw $463 million in outflows over four consecutive sessions between September 8 and 11.
In contrast, Ethereum ETFs maintained consistent inflows. On September 11, the same day Bitcoin products faced significant outflows, Ethereum ETFs recorded $216 million in inflows. BlackRock’s ETHA product was a key driver, posting $148.8 million in inflows on September 11 and $80.5 million on September 14.
This performance follows a strong August for Ethereum ETFs, which saw $1.75 billion in net inflows, their best monthly performance in a year. Cumulative net inflows for Ethereum ETFs have reached approximately $13.5 billion since launch, compared to over $55 billion for Bitcoin ETFs.
The shift is partly attributed to product differentiation, as some Ethereum ETFs now offer staking features that provide yield not available in Bitcoin products. This feature is particularly relevant for institutional investors looking to justify crypto allocations to risk committees.
Macroeconomic factors also played a role, as the mid-September data arrived ahead of anticipated Federal Reserve decisions. Bitcoin, being more liquid and higher-profile, often experiences more volatile positioning during macro events, while Ethereum has shown more stable flows during this period of uncertainty.
Issuers including BlackRock, Fidelity, and Grayscale continue to actively market Ethereum products to institutions and advisors, further establishing distribution channels for the asset class.
