Altcoin ETF Inflows Stagnate Amid Bitcoin Dominance

Spot altcoin exchange-traded fund (ETF) inflows have come to a halt, according to recent data. Despite live products available on the market, assets without near-term catalysts or strong marketing efforts are seeing zero flows.

XRP ETFs, however, continue to attract significant capital. In the second week of May 2026, XRP ETFs recorded $60.5 million in weekly inflows, marking the highest single-week figure of the year. Cumulative XRP ETF inflows have surpassed $1.39 billion.

The Altcoin Season Index remains low, sitting at approximately 24. This is well below the 75 threshold considered true altcoin season. The dominance of Bitcoin, currently around 60%, is also suppressing broader altcoin capital flows.

Analysts point to post-midterm conditions in late 2026 as a potential trigger for resumed spot altcoin ETF inflows. Specifically, they highlight the passage of the CLARITY Act and a drop in BTC dominance below 55% as necessary conditions for renewed interest in these funds.
