Crypto markets ended 2025 on a constructive note, with Bitcoin trading near $88,619 and Ethereum around $2,979 on December 31. The positive momentum was largely driven by a significant rebound in institutional demand through spot exchange-traded funds (ETFs).
U.S. spot Bitcoin ETFs recorded a substantial $355.1 million in net inflows on December 30, marking one of the strongest single-day inflow sessions in the second half of the month. Leading the charge was BlackRock's IBIT with approximately $143.7 million in inflows, followed by Fidelity's FBTC ($78.6 million) and ARK Invest's ARKB ($109.6 million). This surge followed weeks of uneven flows and holiday-driven outflows, suggesting a strategic year-end repositioning by asset managers.
This institutional appetite emerged despite a cautious stance from the Federal Reserve. Following a Federal Open Market Committee meeting, policymakers reiterated that further evidence of sustainably easing inflation would be needed before committing to additional rate cuts in 2026. The strength in Bitcoin ETF inflows, therefore, stood out as a sign that institutional crypto exposure is increasingly being treated as a strategic, long-term allocation rather than a short-term macro trade.
The ETF resurgence extended beyond Bitcoin. Ethereum ETFs returned to net inflows, attracting a combined $67.9 million after a difficult mid-month period, with Grayscale's ETH products accounting for the bulk. Solana-linked ETFs, while smaller in scale, also saw steady interest with $5.2 million in net inflows, led by Bitwise's BSOL and Grayscale's GSOL. Solana traded near $125, maintaining its position as the strongest-performing large-cap altcoin in the ETF universe.
Analysts note that the shifting ETF flows are increasing market volatility. Downside risks of 25% to 40% are being discussed more openly, especially for assets with weaker momentum. In this environment, assets like TRON (TRX), Avalanche (AVAX), Litecoin (LTC), Stellar (XLM), and Bitcoin Cash (BCH) are being monitored for their historical resilience, network utility, and relative liquidity as the market transitions into a potentially more unstable phase.
