Crypto ETFs: Crypto Index ETFs Quietly Emerge

The launch of multi-token crypto products (i.e., crypto index ETFs) signals that many issuers believe the next growth phase in crypto ETFs will be driven by investors who want a rules-based basket approach rather than single asset calls. It mirrors how equity investors often move from single-stock investing to index adoption once an asset class matures, and it also reflects the growing preference among advisors for simpler, portfolio building blocks. But flows into the category have been weak, while single crypto asset ETFs gain significant the attention. I believe this trend will partially reverse over time and we will potentially see more inflows into crypto index ETFs as the number of crypto products becomes too overwhelming to easily perform comparative due diligence. Here is what advisors and investors need to know before making a decision on if/when it is appropriate to invest beyond Bitcoin.

What are crypto index ETFs?

Crypto index ETFs diversify beyond Bitcoin in one product. The majority of these are market-cap weighted and look similar under the hood. At the core, these hold a large amount of Bitcoin (typically around 75%), some Ether (around 15%), XRP (5-6%), Solana (3%), and Cardano (less than 1%). Other allocations are typically less than 1% and include Chainlink, Stellar, and Dogecoin. Most of these also have a small, simple number of holdings (either 5 or 10).

Crypto index products remain comparatively under-the-radar versus single crypto asset ETFs. But they appeal to a specific investor mindset: 1) those that already understand the Bitcoin story and want to expand beyond Bitcoin, and 2) those not necessarily interested in making single asset pick. These baskets can also provide small exposure to assets that may not yet have standalone U.S. spot ETFs (although in small percentages). Stellar and Polkadot, for instance, do not yet have spot ETFs but are found in several crypto index ETFs.

The issue is that many investors seem to like picking the winners. Crypto is an exciting field with some interesting narratives like Solana and XRP. Solana and XRP spot crypto ETFs have both seen relatively significant demand since their launch in October despite falling crypto prices. Both Solana and XRP ETFs have gathered over $1 billion in net inflows in each group in just over a month.

With the split between Bitcoin-only investors and those interested in individual token narratives, there is not yet a large crowd in the middle looking for diversified basket exposure. This will likely change over the next few years as investors navigate an overwhelming number of crypto products (currently there are over 150 crypto ETFs including around 75 launched in 2025).
