Bitcoin spot ETFs attracted $189.3 million in net inflows.

Ethereum spot ETFs recorded $71.47 million in net inflows.

Solana and XRP spot ETFs added $1.58 million and $5.81 million, respectively.

The latest August 18 ETF flows showed broad-based institutional demand, with Bitcoin, Ethereum, Solana, and XRP spot ETFs all recording net inflows totaling roughly $268 million across the four assets. Bitcoin spot ETFs led the market with $189.3 million in fresh inflows, highlighting continued investor interest in the largest cryptocurrency. Ethereum spot ETFs also posted a strong session, attracting $71.47 million in new capital. Meanwhile, Solana and XRP spot ETFs remained in positive territory, adding $1.58 million and $5.81 million, respectively.

Bitcoin and Ethereum Lead Institutional Demand

Bitcoin once again accounted for the largest share of daily ETF inflows, reinforcing its position as the primary destination for institutional crypto investment. Ethereum followed with solid inflows, while Solana and XRP continued to attract smaller but positive allocations.

The four product categories sit at very different stages of their life cycles. US-listed spot Bitcoin ETFs began trading in January 2024, opening regulated, exchange-listed crypto exposure to conventional brokerage accounts, with Ethereum spot ETFs following in July 2024. Solana and XRP spot ETFs are the newest cohort, and their daily flow figures remain far smaller in scale than those of the two larger, longer-established complexes.

Net inflows are recorded when share creations outpace redemptions, meaning new capital entered the funds over the session. Daily flows for these products have alternated between inflows and outflows since launch, which makes a session in which all four categories post net inflows a comparatively broad day of demand.

The broad participation across multiple digital asset ETFs suggests investors maintained confidence across the crypto market rather than concentrating solely on Bitcoin. Daily ETF flows remain a closely watched indicator of institutional sentiment and capital allocation.

Positive Momentum Continues

The latest figures point to continued institutional interest across the major cryptocurrency ETF market. Beyond single-day prints, market observers track cumulative net inflows and total net assets across these funds as a gauge of longer-horizon adoption. With all four spot ETF categories recording net inflows, investors will be watching upcoming trading sessions to see whether the positive momentum continues. Sustained inflows could support broader market sentiment, particularly if accompanied by stronger spot demand and improving on-chain activity.
