US spot Bitcoin ETFs saw net inflows of $175.6 million on October 13, 2026, a figure substantially higher than the $24.8 million in net inflows for US spot Ether ETFs on the same day. This divergence highlights differing investor sentiment towards the two leading digital assets as channeled through regulated investment products.
Over the 30-day period preceding October 13, Bitcoin ETFs attracted approximately $2.06 billion in net inflows. In contrast, Ether ETFs experienced a net outflow of $192 million during the same timeframe. This longer-term trend further underscores a stronger institutional appetite for Bitcoin exposure via ETFs compared to Ether.
Key Fund Performance
Fidelity’s Wise Origin Bitcoin Fund (FBTC) was a significant contributor to the daily inflows, posting $103.1 million. On the Ether side, the Grayscale Ethereum Staking Mini Trust led with $16.7 million in inflows, accounting for a substantial portion of the total Ether ETF inflows for the day.
Volatility and Scale
Despite the positive inflows on October 13, Bitcoin ETFs had experienced significant outflows earlier in the month, with $487 million leaving on October 7 and another $244 million on October 8. This suggests a degree of volatility in investor sentiment even within the Bitcoin ETF market.
The scale of assets managed by each type of ETF also reflects this difference in adoption. As of October 13, spot Bitcoin ETFs held approximately $100.75 billion in net assets, while spot Ether ETFs held around $14.48 billion. Since their launch on January 11, 2024, Bitcoin ETFs have accumulated $57.68 billion in net inflows, compared to $13.16 billion for Ether ETFs.
In terms of market representation, spot Bitcoin ETFs account for roughly 6% of Bitcoin’s market capitalization, while spot Ether ETFs represent about 4.7% of Ether’s market capitalization. These figures indicate that while Bitcoin ETFs hold a larger share of their underlying asset’s market cap, both products are becoming increasingly significant channels for institutional investment.
Spot ETFs offer investors a way to gain exposure to Bitcoin or Ether through traditional brokerage accounts, eliminating the need for direct management of digital wallets and private keys. The daily flow data for these products has become a closely watched indicator of institutional interest in digital assets since the Bitcoin ETFs began trading in January 2024.
