Crypto ETF Flows: Strong ETH and Solana Demand Offset BTC Outflows on December 10 2025
The crypto platform-Traded Fund (ETF) and platform-Traded Product (ETP) market experienced a day of significant rotation on Wednesday, December 10, 2025, as institutional investors intensified their “flight to quality” into select altcoins while BTC saw minimal net inflows following a week of heavy tradeing. The divergent flow metrics highlight a sophisticated rebalancing of risk ahead of the Federal Reserve’s anticipated interest rate announcement later that day, suggesting capital is being moved to assets perceived to have a more favorable near-term risk-reward profile.
Altcoin ETPs Lead the Charge
ETH (ETH) and Solana (SOL) ETPs saw substantial capital influx, signaling strong conviction in their respective ecosystems. ETH (ETH) ETFs dominated inflows, attracting a massive estimated +$117.71 million in a single day. This daily flow accounted for approximately 62% of the total inflows ETH ETPs had viewn over the preceding seven days, demonstrating a highly concentrated surge in demand. This activity suggests renewed institutional interest in ETH, potentially driven by falling platform balances, positive technical price action, and speculation surrounding the asset’s structural scarcity. Similarly, Solana (SOL) ETFs also recorded robust inflows, adding an estimated +$10.23 million. This marked the continuation of a multi-day purchaseing trend for Solana products, which had accumulated approximately $50.42 million over the trailing seven days, confirming Solana’s position as a favored high-growth altcoin exposure vehicle for institutions viewking high-beta exposure.
BTC Funds Stabilize but Remain fragile
In contrast to the strong altcoin purchaseing, BTC (BTC) ETPs struggled to maintain positive momentum on a weekly basis, despite a small daily uptick. These products registered a modest daily net inflow of approximately +$40.87 million (equivalent to +445 BTC at the prevailing price). This positive daily reading provided a brief reprieve from the sustained tradeing pressure the asset has faced. However, when viewed in a broader context, BTC ETFs still reflected a net weekly outflow of approximately -$182.9 million (or -1,992 BTC). This confirms the recent trend where investors have been using the high liquidity of spot BTC ETFs to take profits or de-risk their positions, contributing to the asset’s price consolidation around the $92,000 level. The overall flow picture on December 10th strongly supports the narrative of market rotation and recycled liquidity. Capital is being selectively reallocated from BTC—where recent gains are being realized and short-term macro caution prevails—into major altcoins that are demonstrating technical strength and benefiting from increased institutional utility.
