Solana, XRP ETFs Draw Fresh Inflows as Altcoin Fund Activity Splits

Solana (SOL) and XRP (XRP) spot ETFs in the U.S. continued to attract fresh capital, signaling pockets of resilient 'risk appetite' in the altcoin ETF market even as flows across several smaller products remained largely dormant.

According to data compiled by SosoValue, U.S.-listed XRP spot ETFs posted a net inflow of $2.55 million on June 18 ET, flipping back to net positive after the group was flat the prior session. The entire day’s inflow came from Bitwise’s XRP ETF, while the other four listed products reported no additional creations or redemptions.

Despite the modest daily figure, XRP spot ETFs have built up sizable aggregate positioning. Cumulative net inflows stand at $1.45 billion, with $11.98 million in daily turnover. Total net assets were reported at $994.81 million, equivalent to roughly 1.39% of XRP’s market capitalization—an indicator of how meaningful the ETF wrapper has become for U.S. exposure.

Solana spot ETFs also extended their winning streak, recording $2.99 million in net inflows for a fourth consecutive trading day. As with XRP, the inflow was concentrated in a single product: Bitwise’s Solana ETF, which was the only one among eight funds to show net creations on the day. The group has now accumulated $1.13 billion in cumulative net inflows, supported by $38.30 million in daily volume, while total net assets reached $794.01 million—about 1.96% of SOL’s market cap.

The pattern of concentrated inflows suggests institutional and adviser demand may be selectively routing through the most liquid or most established issuers, rather than lifting the entire category. In practice, that can make headline flow numbers appear steady while masking a bifurcated market—where flagship products see consistent 'liquidity inflow' and smaller tickers struggle to sustain momentum.

Elsewhere in the altcoin ETF complex, activity was muted. Dogecoin (DOGE) spot ETFs, which had briefly resumed inflows after a stretch of flat sessions, returned to a standstill. Chainlink (LINK) spot ETFs remained unchanged for a fifth straight session, while Avalanche (AVAX) spot ETFs stayed flat for a sixth consecutive trading day. Hyperliquid (HYPE) spot ETFs, after attracting new capital for three sessions in a row, also posted a flat read on June 18 ET.

Among single-issuer products, VanEck’s BNB ETF (VBNB) extended its flat streak to five sessions. Canary’s Litecoin spot ETF (LTCC) broke a long run of inactivity with a $317,140 net inflow—the first in 17 trading days. Canary’s Hedera spot ETF (HBAR) was flat for a fourth consecutive session, while 21Shares’ Polkadot spot ETF (TDOT) remained unchanged for an eighth.

The broader takeaway from June 18 is not a sweeping rotation into altcoin ETFs, but a selective bid for a handful of large-cap exposures—particularly SOL and XRP—while the long tail of products continues to show limited day-to-day participation. If sustained, the divergence could reinforce a two-tier market in which only the most actively traded funds meaningfully shape 'price discovery' and sentiment.
