SOL and XRP ETFs See Inflows as BTC, ETH Face Outflows
On Dec. 15, SOL and XRP spot ETFs gained inflows while BTC and ETH ETFs saw major investor outflows.
- Bitcoin and Ethereum ETFs faced large outflows totaling $582M+
- SOL and XRP ETFs attracted net inflows on the same day
- Shift signals changing investor sentiment in altcoins
On December 15, 2025, the crypto ETF market witnessed a notable shift in investor sentiment. Spot exchange-traded funds (ETFs) for Solana (SOL) and Ripple (XRP) recorded net inflows, while Bitcoin (BTC) and Ethereum (ETH) ETFs suffered significant outflows.
According to the latest data, BTC ETFs lost $357.69 million, and ETH ETFs saw $224.78 million in outflows. In contrast, SOL ETFs gained $35.2 million, and XRP ETFs brought in $10.89 million in net inflows.
This shift may reflect a growing appetite among investors for alternative layer-1 tokens that are showing stronger relative momentum or potential upside compared to the larger-cap assets like Bitcoin and Ethereum.
What’s Behind the ETF Flow Shift?
Several factors could be driving this divergence in ETF flows.
Diversification Trends: Investors may now be diversifying their crypto exposure, allocating funds to a broader range of assets rather than concentrating solely on BTC and ETH.
Profit-Taking in BTC and ETH: After recent rallies in both BTC and ETH prices, institutional investors may be locking in profits ahead of year-end. This commonly leads to capital rotation, where funds move from top-performing assets into underperforming or emerging ones.
Rising Interest in Altcoins: Solana has seen a massive resurgence in 2025, driven by network upgrades, growing DeFi activity, and strong ecosystem development. Meanwhile, XRP has gained attention as Ripple continues to expand partnerships globally and regulatory clarity improves in the U.S.
Market Signals Point to Changing Investor Preferences
The inflows into SOL and XRP ETFs, while modest compared to the outflows from BTC and ETH, still indicate a shift in sentiment. It reflects a broader trend where investors are starting to recognize potential in networks beyond the two dominant players.
While Bitcoin and Ethereum remain the foundational pillars of the crypto market, altcoins like Solana and XRP are carving out unique positions—both in technology and investor interest. If this trend continues, we may see a more balanced flow distribution across the crypto ETF space in early 2026.
