Spot Bitcoin ETFs, which allow investors to buy shares tied to Bitcoin’s price, attracted $1.9 billion in net inflows. Spot Ether ETFs, which track Ethereum’s price, drew $697.2 million. Both figures represent the highest weekly inflows for these products in 2026 so far.

Why investors are watching these ETFs

ETFs, or exchange-traded funds, are investment products that let people buy shares representing a basket of assets, like stocks or cryptocurrencies, without owning the assets directly. Spot Bitcoin and Ether ETFs track the current price of Bitcoin and Ethereum, making them a simpler way for investors to gain exposure to these cryptocurrencies.

The recent inflows suggest renewed interest from investors, particularly as crypto prices rise. However, the year-to-date outflows indicate that investor sentiment has been mixed in 2026.
